description: Quantum teleportation plays a key role in modern quantum technologies. Thus, it is of much interest to generate alternative approaches or representations aimed at allowing us a better understanding of the physics involved in the process from different perspectives. With this purpose, here an approach based on graph theory is introduced and discussed in the context of some applications. Its main goal is to provide a fully symbolic framework for quantum teleportation from a dynamical viewpoint, which makes explicit at each stage of the process how entanglement and information swap among the qubits involved in it. In order to construct this dynamical perspective, it has been necessary to define some auxiliary elements, namely virtual nodes and edges, as well as an additional notation for nodes describing potential states (against nodes accounting for actual states). With these elements, not only the flow of the process can be followed step by step, but they allow us to establish a direct correspondence between this graph-based approach and the usual state vector description. To show the suitability and versatility of this graph-based approach, several particular teleportation examples are examined, which include bipartite, tripartite and tetrapartite maximally entangled states as quantum channels. From the analysis of these cases, a general protocol is discussed in the case of sharing a maximally entangled multi-qubit system.

description: The level densities and radiative strength functions (RSFs) of $^{50,51}$V have been extracted using the ($^3$He,$αγ$) and ($^3$He,$^3$He$^{\prime} γ$) reactions, respectively. From the level densities, microcanonical entropies are deduced. The high $γ$-energy part of the RSF is described by the giant electric dipole resonance. A significant enhancement over the predicted strength in the region of $E_γ \lesssim 3$ MeV is seen, which at present has no theoretical explanation.

description: This paper analyzes the factors guiding Internet and e-commerce implementation by agribusiness firms. The relationship between Internet/e-commerce strategies and manager perceptions on the barriers and factors to e-commerce adoption are analyzed in a supply-chain management framework. Using factor analysis and an ordered Probit model, results indicate that the implementation of Internet/e-commerce strategies is more likely to be adopted in larger firms with a global scope. Also, manager perceptions regarding supply-chain functions influencing transaction costs are more strongly associated with Internet/e-commerce adoption than other functions influencing production costs.

description: Coupling by the resonant dipole-dipole energy transfer between cold cesium Rydberg atoms is investigated using time-resolved narrow-band de-excitation spectroscopy. This technique combines the advantage of efficient Rydberg excitation with high-resolution spectroscopy at variable interaction times. The coherent character of the process is studied by back and forth transfer in the np+np ns+(n+1)s reaction. Decoherence in the ensemble has two different origins: the atom motion induced by dipole-dipole interaction and the migration of the s-Rydberg excitation in the environment of p-Rydberg atoms.

description: We show how the theory of the critical behaviour of $d$-dimensional polymer networks of arbitrary topology can be generalized to the case of networks confined by hyperplanes. This in particular encompasses the case of a single polymer chain in a bridge configuration. We further define multi-bridge networks, where several vertices are in local bridge configurations. We consider all cases of ordinary, mixed and special surface transitions, and polymer chains made of self-avoiding walks, or of mutually-avoiding walks, or at the tricritical $Θ$-point. In the $Θ$-point case, generalising the good-solvent case, we relate the critical exponent for simple bridges, $γ_b^Θ$, to that of terminally-attached arches, $γ_{11}^Θ,$ and to the correlation length exponent $ν^Θ.$ We find $γ_b^Θ = γ_{11}^Θ+ν^Θ.$ In the case of the special transition, we find $γ_b^Θ({\rm sp}) = \frac{1}{2}[γ_{11}^Θ({\rm sp})+γ_{11}^Θ]+ν^Θ.$ For general networks, the explicit expression of configurational exponents then naturally involve bulk and surface exponents for multiple random paths. In two-dimensions, we describe their Euclidean exponents from a unified perspective, using Schramm-Loewner Evolution (SLE) in Liouville quantum gravity (LQG), and the so-called KPZ relation between Euclidean and LQG scaling dimensions. This is done in the case of ordinary, mixed and special surface transitions, and of the $Θ$-point. We provide compelling numerical evidence for some of these results both in two- and three-dimensions.

Development of methods for regional flood estimates in the province of British Columbia, Canada
Creators: name: Wang, Yuzhang
Publisher: name: University of British Columbia
Year: 2009

description: Flood estimation in the province of British Columbia is often based on either single-site frequency analysis or graphical peak-flow regionalization procedures. These methods involve large uncertainties, especially at short-term record stations and ungauged sites, because of the vague selection of frequency distributions and delineation of homogeneous regions. To reduce these uncertainties and overcome the drawbacks of the current methods, an innovative regional frequency analysis was proposed in this study. L-moments were used for the three stages, namely delineating and testing homogeneous regions, identifying and fitting regional distributions, and developing regional functions for the transfer of information from gauged to ungauged watersheds. Based on the most recently available flood database, the province of British Columbia was divided into 19 homogeneous regions of which 14 are non-mixture regions and five are mixture regions. A mixture means in some years the annual floods are generated by one mechanism, while in other years they are generated by other physically different mechanisms. It was found that either the generalized logistic (GLOG) or the generalized extreme value (GEV) may be considered as the regional parent distribution for any of the non-mixture regions, whereas the non-parametric distribution can be used for the mixture regions. In the non-mixture regions, hierarchical approaches and regression models were developed for gauged and ungauged watersheds. For the hierarchical approaches, the first two parameters of the GLOG or GEV distribution were estimated from at-site data while the third parameter was from the region. For the regression models, the parameters of the GLOG or GEV distribution were regressed on the catchment size. In the mixture regions, a non-parametric method was combined with the regression method for the development of regional models. Monte Carlo simulation studies showed that the developed hierarchical approaches were substantially more accurate than the single-site methods, especially for long-term flood quantiles. In particular, it was shown that about three times more data were required for the single-site models to be as accurate as the developed hierarchical approaches. The proposed regression models were validated through split-sampling experiments. Statistical tests showed that the quantiles from the regression models were in good agreement with those from actual observations.

description: An equilibrium statistical system is known to be stable if the fluctuations of global observables are normal, when their dispersions are proportional to the number of particles, or to the system volume. A general theorem is rigorously proved for the case, when an observable is a sum of linearly independent terms: The dispersion of a global observable is normal if and only if all partial dispersions of its terms are normal, and it is anomalous if and only if at least one of the partial dispersions is anomalous. This theorem, in particular, rules out the possibility that in a stable system with Bose-Einstein condensate some fluctuations of either condensed or noncondensed particles could be anomalous. The conclusion is valid for arbitrary systems, whether uniform or nonuniform, interacting weakly or strongly. The origin of fictitious fluctuation anomalies, arising in some calculations, is elucidated.

description: We consider three-dimensional (3D) localization and imaging of space debris from only one two-dimensional (2D) snapshot image. The technique involves an optical imager that exploits off-center image rotation to encode both the lateral and depth coordinates of point sources, with the latter being encoded in the angle of rotation of the PSF. We formulate 3D localization into a large-scale sparse 3D inverse problem in the discretized form. A recently developed penalty called continuous exact l0 (CEL0) is applied in this problem for the Gaussian noise model. Numerical experiments and comparisons illustrate the efficiency of the algorithm.

description: Production strategies pursued by households and individuals in a peasant community of the Bolivian Altiplano are shaped by access to resources, social networks and institutions, wealth, and the ability to develop urban rural linkages. In times of climatic stress such as the low rainfall of 1995, the household economic portfolio shifts to activities less vulnerable to climate. The ability to shift is conditioned by access to resources, social capital, stage in the life cycle and wealth. A typology developed to understand how strategies take shape during a drought is used to evaluate access to information during el Niño (1997-8) and impacts on potato production in 1998-99. The relationship between diversification and use of climate forecasts (local and modern) is evaluated. The study proposes that diversification and use of forecasts may go hand in hand, and should be considered in the profile of potential users.

description: The rise in the domestic price of oil products implied by the new import parity pricing policy for domestic crude oil is likely to pose some problems for macroeconomic management. In this paper an attempt has been made to quantify the short-run adjustment problems involved, using the ORANI 78 model of the Australian economy. Results are presented for a range of variables of interest, including macroeconomic variables, industrial and workforce composition and farm incomes. With fixed real wages, farm incomes are projected to decline by between 6 and 8 per cent.

description: Quantum mechanics is often developed in the position representation, but this is not necessary, and one can perform calculations in a representation-independent fashion, even for wavefunctions. In this work, we illustrate how one can determine wavefunctions, aside from normalization, using only operators and how those operators act on state vectors. To do this in plane polar and spherical coordinates requires one to convert the translation operator into those coordinates. As examples of this approach, we illustrate the solution of the Coulomb problem in two and three dimensions without needing to express any operators in position space.

description: The primary purposes of this study are to measure major relationships describing the responses of different components of sheep and beef farming capital stock in New Zealand to changes in economic conditions, and to investigate the way in which this capital stock has changed over time. These objectives are pursued by attempting to specify an econometric model that recognises joint production between sheep and beef cattle and also takes account of joint firm/household decision making. Aggregate New Zealand data for the period 1952/53 to 1973/74 are fitted to the model using Full Information Maximum Likelihood estimation.

description: The presence of noise in non linear dynamical systems can play a constructive role, increasing the degree of order and coherence or evoking improvements in the performance of the system. An example of this positive influence in a biological system is the impulse transmission in neurons and the synchronization of a neural network. Integrating numerically the Fokker-Planck equation we show a self-induced synchronized oscillation. Such an oscillatory state appears in a neural network coupled with a feedback term, when this system is excited by noise and the noise strength is within a certain range.

description: Substantial variations in landowner's share under sharecropping arrangements are documented. Partial relationships between landowner's share and land quality and between landowner's share and physiological population density are explained by extensions of the competitive theory of share tenancy. It is shown that high landowner's share can be expected to be associated with high land quality and or high physiological density. The tendency for increases in population to be associated with increases in landlords' shares can be ameliorated by land-saving technological change.

description: Our starting point is a class of braid matrices, presented in a previous paper, constructed on a basis of a nested sequence of projectors. Statistical models associated to such $N^2\times N^2$ matrices for odd $N$ are studied here. Presence of $\frac 12(N+3)(N-1)$ free parameters is the crucial feature of our models, setting them apart from other well-known ones. There are $N$ possible states at each site. The trace of the transfer matrix is shown to depend on $\frac 12(N-1)$ parameters. For order $r$, $N$ eigenvalues consitute the trace and the remaining $(N^r-N)$ eigenvalues involving the full range of parameters come in zero-sum multiplets formed by the $r$-th roots of unity, or lower dimensional multiplets corresponding to factors of the order $r$ when $r$ is not a prime number. The modulus of any eigenvalue is of the form $e^{μθ}$, where $μ$ is a linear combination of the free parameters, $θ$ being the spectral parameter. For $r$ a prime number an amusing relation of the number of multiplets with a theorem of Fermat is pointed out. Chain Hamiltonians and potentials corresponding to factorizable $S$-matrices are constructed starting from our braid matrices. Perspectives are discussed.

description: Reconstructing the Galactic evolution of lithium (Li) is the main tool used to constrain the source(s) of Li enrichment in the Galaxy. Recent results have suggested a decline in Li at supersolar metallicities, which may indicate reduced production. We exploit the unique characteristics of the Gaia-ESO Survey open star cluster sample to further investigate this issue and to better constrain the evolution of Li at high metallicity. We trace the the upper envelope of Li abundance versus metallicity evolution using 18 clusters and considering members that should not have suffered any Li depletion. At variance with previous claims, we do not find any evidence of a Li decrease at high metallicity. The most metal-rich clusters in the sample ([Fe/H] about 0.3) actually show the highest Li abundances, with A(Li) > 3.4. Our results clearly show that previous findings, which were based on field stars, were affected by selection effects. The metal-rich population in the solar neighbourhood is composed of relatively old and cool stars that have already undergone some Li depletion; hence, their measured Li does not represent the initial interstellar medium abundance, but a lower limit to it.

Exactness of the cluster variation method and factorization of the equilibrium probability for the Wako-Saito-Munoz-Eaton model of protein folding

description: I study the properties of the equilibrium probability distribution of a protein folding model originally introduced by Wako and Saito, and later reconsidered by Munoz and Eaton. The model is a one-dimensional model with binary variables and many-body, long-range interactions, which has been solved exactly through a mapping to a two-dimensional model of binary variables with local constraints. Here I show that the equilibrium probability of this two-dimensional model factors into the product of local cluster probabilities, each raised to a suitable exponent. The clusters involved are single sites, nearest-neighbour pairs and square plaquettes, and the exponents are the coefficients of the entropy expansion of the cluster variation method. As a consequence, the cluster variation method is exact for this model.

description: This investigation examines the impact of intensive farm management advice on levels and productivities of resource use on samples of farms. A total of 60 members of 13 farm management advisory services and 60 non-members, matched by locality, were studied in two farming regions of Western Australia. A production model has been formulated and analysed which discriminates between effects of differences and changes in resource use and productivity over time and between members and non-members. Major differences between members and non-members over time have been rates of growth of inputs and outputs rather than systematic changes of production relationships.
Analysis of three factors influencing the performance of fishing cooperative organizations of Yucatan, Mexico
Creators: name: Torres-Lara, Ricardo
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of the study is to explore and understand the influence of several factors that potentially contribute to differences in performance of cooperative fisheries organizations in Yucatan State, Mexico. The three independent variables examined in this study, as influences on fisheries cooperatives performance are organizational issues, market structure issues, and the ability of cooperatives to adapt to external change. These factors were identified as potentially important for fisheries cooperatives performance in the region based on (1) my six-year experience working with these fisheries cooperatives as a fisheries manager in Yucatan State, and (2) a review of the relevant literature on organizational and economic influences on cooperatives performance. The performance of fisheries cooperatives, the dependent variable in this study, is expressed in two alternative ways. One, based on the judgment of members, uses the stated satisfaction of a cooperative's member with its performance. A second approach for characterizing performance is based on the physical production of the cooperatives in terms of the average catch over a five-year period. The central tool for data collection and analysis is a mixed-methods design that includes a survey, face-to-face interviews, personal observation, and secondary sources of information. I calculated non-parametric correlation coefficients (Spearman's rho) between the independent and dependent variables. All correlations were statistically significant at the 0.01 level. These results support the predicted relationship between the variables that is, that cooperatives with more operational rules, stronger market position, and higher adaptive ability are more likely to be have members more satisfied and to report higher catches. Multivariate analyses show that the most important variable influencing cooperatives' performance is the number of operational rules, which in fact explain a little bit more than 70% of the performance variability, expressed as average catch per cooperative. The results of the study are discussed in terms of their empirical support for social science theories, their contribution of new theoretical insights into the study of cooperatives, and the implications for the management of natural resources.

description: Obesity has been linked with numerous health issues as well as an increased risk of breast cancer. Although effects of direct obesity in patient outcomes is widely studied, effects of exposure to obesity-related systemic influences in utero have been overlooked. In this study, we investigated the effect of multigenerational obesity on epithelial cell migration and invasion using decellularized breast tissues explanted from normal female mouse pups from a diet induced multigenerational obesity mouse model. We first studied the effect of multigenerational diet on the mechanical properties, adipocyte size, and collagen structure of these mouse breast tissues, and then, examined the migration and invasion behavior of normal (KTB-21) and cancerous (MDA-MB-231) human mammary epithelial cells on the decellularized matrices from each diet group. Breast tissues of mice whose dams had been fed with high-fat diet exhibited larger adipocytes and thicker and curvier collagen fibers, but only slightly elevated elastic modulus and inflammatory cytokine levels. MDA-MB-231 cancer cell motility and invasion were significantly greater on the decellularized matrices from mice whose dams were fed with high-fat diet. A similar trend was observed with normal KTB-21 cells. Our results showed that the collagen curvature was the dominating factor on this enhanced motility and stretching the matrices to equalize the collagen fiber linearity of the matrices ameliorated the observed increase in cell migration and invasion in the mice that were exposed to a high-fat diet in utero. Previous studies indicated an increase in serum leptin concentration for those children born to an obese mother. We generated extracellular matrices using primary fibroblasts exposed to various concentrations of leptin. This produced curvier ECM and increased breast cancer cell motility for cells seeded on the decellularized ECM generated with increasing leptin concentration. Our study shows that exposure to obesity in utero is influential in determining the extracellular matrix structure, and that the resultant change in collagen curvature is a critical factor in regulating the migration and invasion of breast cancer cells.

description: The most effective method to manage mosquito population is to kill aquatic stages (egg, larva and pupa) of mosquito than the aerial adult stage. The susceptibility test was evaluated against larvae of Anopheles stephensi in the laboratory conditions maintaining the temperature of 27±2ºC and 70±80% Relative Humidity. The combination of the seed extracts of Trachyspermum ammi (ajwain), mustard oil and naphthalene were taken in the ratio 1:2:1. Results of the larval susceptibility test after 25 hours of treatment revealed that the combination of the three components are significant in killing the larval population of Anopheles stephensi to some extent. It has also been noticed that the rise in dose from 1ml/199ml to 7ml/99ml of water increased the larval mortality.

description: Skyrmions have attracted significant interest due to their topological spin structures and fascinating physical features. The skyrmion phase arises in materials with Dzyaloshinskii-Moriya (DM) interaction at interfaces or in volume of non-centrosymmetric materials. However, although skyrmions were generated experimentally, one critical intrinsic relationship between fabrication, microstructures, magnetization and the existence of skyrmions remains to be established. Here, two series of CoFeB ultrathin films with controlled atomic scale structures are employed to reveal this relationship. By inverting the growth order, the amount of defects can be artificially tuned, and skyrmions are shown to be preferentially formed at defect sites. The stable region and the density of the skyrmions can be efficiently controlled in the return magnetization loops by utilizing first-order reversal curves to reach various metastable states. These findings establish the general and intrinsic relationship from sample preparation to skyrmion generation, offering an universal method to control skyrmion density.

A linear programming model considered appropriate for solving such models is described, in which the multi-dimensional criterion function is expressed as a linear combination of the appropriately-weighted objectives. An empirical application is then discussed, the objectives of the firm being the maximization of tax-free cash and assets on hand at the end of the planning period. Finally, the appropriate length of the planning horizon, and some approaches to capital budgeting under non-certainty, are discussed.

description: A translation invariant N-polaron system is investigated at arbitrary electron-phonon coupling strength, using a variational principle for path integrals for identical particles. An upper bound for the ground state energy is found as a function of the number of spin up and spin down polarons, taking the electron-electron interaction and the Fermi statistics into account. The resulting addition energies and the criteria for multipolaron formation are discussed.

description: We present an analytical model to account for the inertial dynamics of a magnetic vortex. The model is based on a deformation of the core profile based on the Döring kinetic field, whereby the deformation amplitudes are promoted to dynamical variables in a collective-coordinate approach that provides a natural extension to the Thiele model. This extended model accurately describes complex transients due to inertial effects and the variation of the effective mass with velocity. The model also provides a quantitative description of the inertial dynamics leading up to vortex core reversal, which is analogous to the Walker transition in domain wall dynamics.

description: In this note, we determine the representation content of the free, large N, SU(N) Yang Mills theory on a sphere by decomposing its thermal partition function into characters of the irreducible representations of the conformal group SO(4,2). We also discuss the generalization of this procedure to finding the representation content of N=4 Super Yang Mills.

UNITED STATES OF AMERICA – Mississippi • 183 isolated teeth; Catahoula Formation; SC 2013.28.643 (Fig. 28A–C), SC 2013.28.644 to 28.650, SC 2013.28.651 (Fig. 28D–F), SC 2013.28.652, SC 2013.28.653, SC 2013.28.654 (2 teeth), SC 2013.28.655 (11 teeth), SC 2013.28.656 (16 teeth), SC 2013.28.657 (20 teeth), SC 2013.28.658 (21 teeth), SC 2013.28.659 (20 teeth), SC 2013.28.660 (13 teeth), SC 2013.28.661 (37 teeth), SC 2013.28.662 (17 teeth), SC 2013.28.663 (15 teeth).
Description
Isolated teeth are highly laterally compressed (labio-lingually) and approximately as tall (apico-basally) as they are elongated (mesio-distally). The crown constitutes the upper two-thirds of a tooth and is covered with smooth enameloid. The labial crown face is weakly convex and the lingual face weakly concave (Fig. 28C, F). In mesial/distal view, the crown may be lingually curved. In labial/lingual view, unworn teeth have a roughly rhomboidal outline. The mesial margin may be uniformly convex or sinuous, with the basal portion being most convex but transitioning apically to concave. The distal margin is sinuous, with the basal portion being most convex but transitioning apically to concave. The apical part of the crown is formed into a cusp-like projection (Fig. 28B). The crown tapers basally towards a narrow bony projection, and the crown foot is marked by the enameloid boundary (Fig. 28E).
Remarks
Our sample includes teeth that are worn to varying degrees. These teeth demonstrate that the cuspidate crown apex exhibits the initial signs of in vivo wear (polished and somewhat flattened wear facet), and with continued use the cusp is worn completely away to a flat, relatively horizontal surface that reveals the internal dentine (compare Fig. 28A to D). Some teeth are worn nearly to the crown base, indicating a long period of tooth retention within the jaws and possibly pointing to a durophagous diet.
Diplodus sp. was recently reported from the upper Rupelian Givhans Ferry Member of the Ashley Formation in Dorchester County, South Carolina by Cicimurri et al. (2022). These teeth are easy to distinguish from those of all other bony fishes by their laterally compressed crowns with sinuous anterior and posterior margins. Our Catahoula Formation teeth represent the first occurrence of this taxon from the Gulf Coastal Plain of the USA.

Information Communication Technologies in Teaching English as a Foreign Language: Teacher Perspective
Creators: name: Paneru Dev Raj

Subjects: Information communication technology, English as a foreign language, Exemplary teacher, Communicative approach, Educational significance

description: This phenomenological case study explores the status of information communication technology integration in teaching English as a foreign language in Czech elementary schools from the teacher perspective. Technologies are significantly emerged educational components in European school, yet, little is known how these affect the process of teaching-learning linking teacher practices in class considering the development of learning English upon communication skills as defined by intercultural dimension. Due to the persisting inconsistencies between educational perspectives and teachers’ practices in response to an ever-increasing need of achieving the educational significance of modern information technologies, the phenomenon i.e. technology integration in teaching English with a goal of learning upon skills of communication scopes interactive research participation on comprehensive focus. The research on comprehensive focus is idealized on the scheme of exploring this phenomenon on constructing learning as a better substitute of the one limitedly designed to reporting the increasing use of technologies with a mechanical educational focus. Studies on the phenomenological concept that lends subjectivity epistemology in (social) construction do bring some comprehensive ideas in this regard as, teachers under such model develop competencies and practice technology integration on constructing learning within 21st-century school classrooms on the interface of multiple contexts. However, along with existing research approaching this phenomenon in an inconsistent perspective, phenomenological studies exploring educational potentials of technologies in teacher’s qualitative pedagogical perceptions, skills, and practices of using technologies on comprehensive focus, are still very few in the European setting. Thus, this phenomenological case study explored how technologies are part of the exemplary English teachers everyday teaching in the selected Czech Elementary Schools. The study found the exemplary (teacher) practitioners significantly interactive in their pedagogical perceptions, skills of use, and reflections regarding their practice of technology integration in teaching English within the intercultural theme of communication upon developing the phenomenon as a learning process. Though differences of stimuli and barriers as encountered by each teacher regarding the use of individual technologies in the class were individually contextualized

description: We analyze the stationary problem for the Toda chain, and show that arising geometric data exactly correspond to the multi-support solutions of one-matrix model with a polynomial potential. For the first nontrivial examples the Hamiltonians and symplectic forms are calculated explicitly, and the consistency checks are performed. The corresponding quantum problem is formulated and some its properties and perspectives are discussed.

BCVEGPY2.0: A upgrade version of the generator BCVEGPY with an addendum about hadroproduction of the $P$-wave $B_c$ states

description: The generator BCVEGPY is upgraded by adding the hadroproduction of the $P$-wave excited $B_c$ states (denoted by $B_{cJ,L=1}^*$ or by $h_{B_c}$ and $χ_{B_c}$) and by improving some features of the original one as well. We denote it as BCVEGPY2.0. The $P$-wave production is also calculated by taking only the dominant gluon-gluon fusion mechanism (with the subprocess $gg\to B_{cJ,L=1}^*+\bar{c}+b$ being dominated) into account as that for $S$-wave. In order to make the addendum piece of the upgraded generator as compact as possible so as to increase its efficiency, we manipulate the amplitude as compact as possible with FDC (a software for generating Feynman diagrams and the algebra amplitudes, and for manipulating algebra formulae analytically etc) and certain simplification techniques. The correctness of the program is tested by checking the gauge invariance of the amplitude and by comparing the numerical results with the existent ones in the literature carefully.

Towards genetic modification of the lignin biosynthetic pathway in interior spruce (Picea glauca x engelmanni complex)
Creators: name: Gray-Mitsumune, Madoka
Publisher: name: University of British Columbia

description: Although the lignin biosynthetic pathway has been altered successfully in angiosperm species via genetic engineering approach, this has not yet been achieved in gymnosperm species. Therefore, the goal of my thesis research was to apply the transgenic approach to economically important interior spruce (Picea glauca x engelmanni complex). In the first half of my thesis, the poplar PAL2-GUS fusion gene was introduced into hybrid poplar (Populus tremula x P. alba) and interior spruce in order to evaluate the potential use of this promoter for directing xylem-specific gene expression. In transgenic poplar, the poplar PAL2 promoter directed the expression of the GUS gene in the tissues associated with synthesis of phenolic compounds (epidermal/subepidermal cells) and in the tissues associated with lignin synthesis (xylem and phloem cells). In contrast, in transgenic spruce, the activity of the poplar PAL2 promoter was detected only in the tissues associated with lignin and suberin synthesis. The differences in the activity of the poplar PAL2 promoter between the two hosts suggest that the gene regulation system that leads to the synthesis of essential structural components such as lignin and suberin is more likely to be conserved than that leading to the synthesis of specialized phenolic compounds. The second half of this thesis investigated a contribution of coniferin (β-glucosidase (CG) in lignin synthesis in spruce. CG is believed to be involved in the last steps of the lignin biosynthetic pathway by releasing the lignin precursor, coniferyl alcohol, from its glucosides form, coniferin, before polymerization in the cell wall. An antisense construct against the CG gene was prepared using the lodgepole pine CG cDNA sequence and was introduced into interior spruce. Among 45 antisense lines examined, no transgenic lines contained reduced levels of endogenous CG mRNA levels. The failure of the antisense CG gene to cause inhibitory effects on the endogenous CG expression levels in transgenic spruce could be attributed to low expression of the antisense gene, or to insufficient sequence homology between the antisense and target CG sequences. To my knowledge, this is the first study to employ an antisense approach in a gymnosperm species
