Analisis Pertumbuhan Garut (Marantha arundinaceae) Pada Beberapa Tingkat Naungan

Arrowroot is a plant that potential to be one of the alternative food source for the community. The intensity of the light received by the plant is one of the influential factors important for plant growth. This study was conducted to determine the arrowroot plant growth analysis at different light. This research was conducted at the Experimental Farm Faculty of Agriculture, University of Sebelas Maret in Jumantono Karanganyar. This study uses a randomized block design Complete (RAKL) one treatment factor with four levels ie without shade, 31% shade, 51% shade and 73% shade. Data were analyzed by analysis of variance and if there is a significant difference continued with DMRT (Duncan Multiple Range Test) level of 5%. The results showed that the treatment of 51% shade known to give better growth results in some growth variables observed were plant height, leaf area index (LAI), segment length and chlorophyll contents.
A Monoclonal Antibody Against the PSTAIR Sequence of p34cdc2, Catalytic Subunit of Maturation‐Promoting Factor and Key Regulator of the Cell Cycle

A homolog of the serine/threonine protein kinase (p34cdc2), encoded by the cdc2+ gene of the fission yeast (Schizosaccharomyces pombe), is a catalytic subunit of maturation‐promoting factor and a key regulator of the cell cycle. We have raised a monoclonal antibody against the most conserved amino acid sequence, the PSTAIR sequence (EGVPSTAIREISLLKE) of p34cdc2 This antibody recognizes 31–34 kDa proteins by immunoblotting in all species examined so far. The proteins recognized by the anti‐PSTAIR antibody are probably either p34cdc2 itself or proteins highly homologous to p34cdc2 in the given species, since, in all species studies to date, they are all precipitated with p13suc1, the fission yeast suc1+ gene product, which binds to p34cdc2 with high specificity. The anti‐PSTAIR immunoprecipitate had no histone H1 kinase activity and did not contain cyclin B, suggesting that the PSTAIR region is masked when p34cdc2 forms a complex with cyclin B as an active kinase. Immunoblotting with the anti‐PSTAIR antibody demonstrated that the fastest‐migrating form of p34cdc2 homologues becomes abundant, when oocytes mature or the cell enters M phase. The possible significance of this observation is discussed in relation to the phosphorylation and activity state of p34cdc2 The observed broad cross‐reactivity of the anti‐PSTAIR antibody against p34cdc2 homologues in various species should permit us to examine the role of p34cdc2 homologues in the regulation of the cell cycle in a variety of organisms.
Lessons in Ecosystem Management from Management of Threatened and Pest Loranthaceous Mistletoes in New Zealand and Australia

Loranthaceous mistletoes are interesting because of their complex dependence on suitable host trees and avian dispersers and because of their patchy distribution at the landscape level. Although their over‐ and under‐abundance in Australia and New Zealand have been widely documented, little attention has been given to the need for an ecosystem approach to their management. Although the current status of mistletoes is very different in Australia and New Zealand, some of the causal factors and the long‐term effects of changes in mistletoe abundance are similar in the two countries. We suggest that mistletoe abundance in pre‐European landscapes was dependent on a series of evolutionary and environmental filters relating to host specificity, pollination, dispersal, infection, environmental habitat quality, predation, and disturbance. European settlement modified these filters in a number of ways, resulting in either increases or decreases in mistletoe abundance. The three broad groups of changes that have occurred with European settlement involve fragmentation, predation, and altered disturbance regimes. Although managers have usually addressed mistletoe over‐ or under‐abundance with short‐term solutions (e.g., pruning infected trees), we suggest that management must address the underlying causes of the problems involving mistletoes. This requires an ecosystem approach to management that addresses both the direct and indirect causes of the current status of mistletoes.
RESPONSE OF SOME BREAD WHEAT CULTIVARS TO SALINITY STRESS BY RE-USE OF SEA WATER UNDER NORTH SINAI CONDITIONS

Water salinity is a limiting factor stressed plants and associated with low wheat productivity in new reclaimed areas in Egypt such as North Sinai. Sea water is available water resources and renewable and non-exploited, it is necessary to maximize use of this water through scientific research for use in irrigation of wheat, to increase the cultivated area and thus, increase production towards self-sufficiency. So, two field experiments were carried out at Faculty of Environmental Agricultural Sciences, EIArish, Suez Canal University, during 2012/2013 and 2013/2014 seasons aiming to investigate the response of three wheat cultivar (Triticum aestivum. L.; Masr1, Masr2, Sakha93) to four mixing ratios between well-water and sea water (control, 3:1, 2:1 and 1:1). Plants were subjected to salinity treatments at 60 days after sowing (DAS). Results showed that Masr2 and Masr1cvs were superior for yield and its attributes, the superiority was obtained from Masr2 cv as well as seed content of proline and protein. Also, dry leaf content of Na and Cl were higher for Masr2 as compared to the other studied cultivars under low mixing ratio (3:1 Well water: Sea water), while, the K concentration was decreased with the same treatment of Masr2. For soil analysis, EC, Na , Mg, K, HCO3 -2 and Cl increased but Ca decreased under the highest mixing ratio (1 Well water: 1 Sea water). So, it could be recommended to cultivate Masr2 wheat cultivar under North Sinai conditions, using mixing ratio 3 Well water : 1 Sea water to maximize the benefit of sea water and gain economic productivity of bread wheat in this area and similar regions.
Système de recombinaison Xer chez Staphylococcus aureus

The Xer recombination system is involved in the monomerisation of bacterial replicons, such as plasmids and chromosomes, in a wide variety of bacteria. This system is a site-specific recombination system comprised of two tyrosine recombinases, XerC and XerD, which act in concert to convert dimeric chromosomes to monomers by acting at a specific site near the terminus of replication called the dif site. Xer genes and their site of action have been identified in many gram positive and gram negative bacteria. Staphylococcus aureus represents a gram positive bacterium containing a XerCD/dif system. It is a bacteria implicated in many human diseases, such as skin infections, gastroenteritis and toxic shock syndrome, to name a few. Although the genes encoding the XerC and XerD proteins have been identified, not much is known about their mode of action on the dif site. Mutations in xerC have been obtained, but none in xerD, suggesting that this gene may be essential for this organism. The work presented in this paper has allowed us to better understand the XerD protein of S. aureus, not only in the sequencing of the xerD gene but also in the performing of DNA binding assays. It has been shown that XerD binds to the dif site of E. coli, not only alone but also in cooperativity with E. coli XerC. S. aureus XerD is also capable of complementing the mutated XerD protein in E. coli when it comes to chromosomal recombination. However, it does not demonstrate this same ability to complement XerD regarding recombination at the plasmidic cer sites.
Contraction-induced elevation of heat shock protein 72 mRNA content in isolated single skeletal muscle fibers

Heat shock protein 72 (HSP72) is a cytoprotective element that is induced during conditions of cell stress, and which has been shown to restore intracellular homeostasis following cell stress in a variety of tissues, including skeletal muscle. Exercise is a non-specific stress, particularly to skeletal muscle, and it has been previously demonstrated in whole animal and human preparations that exercise can induce elevations in skeletal muscle HSP72 transcription. However, due to fiber -type and muscle recruitment heterogeneity, generation of heat, and the multitude of intracellular disruptions which may occur during whole body exercise, the mechanisms of transcriptional activation remain unknown. This dissertation extends previous knowledge of exercise- induced HSP72 activation from whole animal and human models to the single cell level. Specifically, this dissertation describes the development of an isolated single skeletal muscle fiber model of contraction- activated elevation in HSP72 mRNA via development of quantitative PCR methodology enhanced for these single fibers. This model is used to demonstrate the temporal kinetics of contraction-induced increases in HSP72 mRNA in skeletal muscle, and to test the hypotheses that increased HSP72 mRNA transcription following contractions in single skeletal muscle fibers is independent of the development of heat or extracellular signaling sources, and dependent on the development of fatigue, and on fiber type. Finally this model is employed to test the hypotheses that free cytosolic Ca2+, alterations in phosporylation potential and/or reactive oxygen species generation contribute to contraction-induced elevations of HSP72 mRNA in single skeletal muscle fibers
What relative seafood prices can tell us about the status of stocks

Changes in the distribution of seafood prices can provide useful insights into the availability of different species to fishermen and to fish markets. We propose a log-relative-price-index (LRPI) and demonstrate how such a concept might be useful for exploring long-term changes in wild fish communities as a result of intensive exploitation. We estimate the LRPI for 26 fish species in the Celtic Sea (UK) and for 33 species on Italian fish markets. In both systems the LRPI changed significantly during recent decades, and in the Celtic Sea this probably resulted from a decline in the availability of high trophic level target species such as cod and hake as well as an increase in the availability of low trophic level pelagic species. By contrast, the LRPI of Italian fishes remained relatively constant from 1972 to 1980, but declined thereafter as a result of widespread expansion in fin-fish aquaculture, and a consequential increase in the supply, and hence decrease in the price of high trophic level fish such as seabass and seabream.
The Evolution of Avian Breeding Systems

The Evolution of Avian Breeding Systems deals with three of the most conspicuous and fascinating aspects of the reproductive biology of birds: sexual selection, parental care, and mating systems. Ever since Darwin, birds have provided much of the stimulus for study of these interrelated topics. Researchers have been fascinated by the extent of sexual dimorphism in plumage colours among avian species, and the puzzling development of flamboyant ornamentation or complex courtship displays in male birds. This book provides empirical assessments of the main theories of mate choice by females, and also includes related topics such as the role of sexual selection in speciation. Although most avian species are socially monogamous, others exhibit polygyny, cooperative and classical polyandry, or lek-promiscuity. The effects of extra pair copulations on paternity, as well as their possible effects on the evolution of mating systems are also considered. Chapters devoted to each of the major mating system summarize current thinking about the factors maintaining them. Throughout the book, theoretical discussion is illustrated with examples, drawn from work on a wide range of avian species. This is the first book to combine the themes of sexual selection, parental care, and mating systems, and to focus exclusively on birds. It will be welcomed by researchers in animal behaviour and ornithology with an interest in mating systems, as well as by graduate and advanced undergraduate students taking courses in this area. It is illustrated throughout with original line drawings.

Using Muon Radiography to map the Bedrock Geometry underneath an active Glacier: A Case Study in the Central Swiss Alps

In recent years, muon radiography has been successfully applied to tackle geological issues and has enjoyed an increasing interest, mainly because this methodology enriches the geophysical arsenal by another shallow subsurface imaging tool that may give independent constraints on material density. Muons that originate from the collision of cosmic particles with Earth’s atmosphere are able to penetrate the material in question and can finally be recorded by a detector. The irradiation intensity can then be inverted to the density of the traversed material. Various successful two-dimensional attempts have already been made to image e.g. magma chambers inside volcanoes (Lesparre et al., 2012; Nishiyama et al., 2014; Tanaka et al., 2005), but this method has yet to be applied for mapping the base of glaciers, where the density contrasts between ice and underlying bedrock are even greater than those between magma and host rock. While a high Alpine setup limits the possibilities to deploy traditional geophysical methods for surveying the base of glaciers (because of inaccessible terrain, poor infrastructure or the presence of water in the ice), muon radiography might prove to be a promising alternative. The muon intensity data from stereo observation can be related to the three-dimensional geometry of the interface between the glacier and its bedrock. Given a suitable input model, this relation can be solved within the framework of geophysical inverse problems. The final model then gives geologists invaluable information on erosional mechanisms underneath active glaciers, as this has not yet been observed. We test this methodology for a site within the Jungfrau region, situated in the central Swiss Alps. Our first goal is to demonstrate the feasibility of the method through a case study at the Eiger glacier, starting from a toy model in a first phase and continuing with real data in a second phase. For this purpose, we installed cosmic-ray detectors at two sites inside the Jungfrau railway tunnel that traverses the rock underneath our target glacier. In order to achieve a high angular resolution, emulsion film detectors will be used. Compared to scintillation detectors, we gain also the advantage that no in-situ power supply is needed.
Amino acid content and protein solubility of feather meal as affected by different processing conditions

The effect of processing conditions on feather meal protein was studied by multiple regression technique. Changes in amino acid composition, protein in vitro digestibility and solubility due to chemical and enzymatic treatments were in­ vestigated. It was concluded that in most cases it is difficult to distinguish the effect of processing on feather meal quality from the corresponding effect on amino acid profile and digestibility in vitro. It is therefore critical that the bioavailability of feather meal protein-amino acids be known. evaluation of the Abstract. Amino acid digestibility determinations by excreta analysis and estima­ tions of ileal and plasma amino acid levels in young chickens proved that processing can affect digestibility of feather meal amino acids to the animal. It was concluded that although ileal and plasma studies may provide useful information on the rela­ tive digestibility of dietary feather meal protein, quantitative digestibility measure­ ments by excreta analysis of the individual amino acids have to be used for feather meal quality evaluation.
The Ribonucleotide Reductase Family : Genetics and Genomics

Ribonucleotide reductase (RNR), a universal enzyme present in essentially all living cells and organisms, has a central role in DNA replication and repair by catalyzing production of deoxyribonucleotides from the corresponding ribonucleotides. Three major classes of RNRs are known, differing in their cofactor requirements: class I RNRs (with subclasses Ia and Ib) carry a stable tyrosyl radical and are oxygen-dependent, class II RNRs require the vitamin B12 cofactor 5’-deoxyadenosylcobalamin and are oxygenindependent, and class III RNRs carry a stable glycyl radical and are oxygen-sensitive. Despite these differences, all classes have a similar reaction mechanism and the same highly specific catalytic core structure, indicating that they evolved from a common ancestor. Biochemical studies of RNRs from selected model organisms in combination with the vast number of deduced RNR sequences from publicly available complete genomic sequences show that whereas eukaryotes and their viruses with few exceptions contain only class Ia RNRs, all three major RNR classes are found among prokaryotes and bacteriophages and quite often one organism encodes more than one class of RNR. They are compiled in an open access database, called RNRdb for Ribonucleotide Reductase database that is available at http://rnrdb.molbio. su.se. RNRs are produced in a strictly controlled way depending upon growth phase and environmental cues. We describe a comprehensive summary of how the expression of RNR genes is regulated in several eubacterial organisms and in yeast. Due to RNR’s importance for the realization of DNA replication, it has been recognized as a possible target for antiproliferative Eduard Torrents, Margareta Sahlin and Britt-Marie Sjoberg 2 therapy. We present a comprehensive summary of RNR-specific inhibitors that have reached clinical trials and/or are currently used in clinical therapy.
C-Myc et lymphomagenèse dans les cellules B infectées par le virus d’Epstein-Barr

Ce travail visait a etudier l’implication de l’oncogene c-myc dans la lymphomagenese, et ce dans un contexte d’infection des cellules B par le virus d’Epstein-Barr (EBV). Il s’est articule autour de trois axes. Dans un premier temps, nous avons montre que les facteurs c-Myc et NF-κB sont les deux principaux systemes transcriptionnels actives dans les cellules B EBV+ en latence III, responsables de leur phenotype, de leur profil de proliferation et de leurs proprietes biologiques. Nous avons ensuite initie un travail concernant l’etude des roles de c-Myc et de l’EBV dans la regulation de l’expression d’une molecule de co-signalisation de la reponse immune : la proteine B7-H1. Nous montrons que l’EBV augmente l’expression de cette proteine, alors que c-Myc la reprime, aux niveaux transcriptionnel et de son export a la membrane cellulaire. Enfin, nous avons elabore de nouveaux vecteurs placant l’oncogene c-myc (ou le gene rapporteur luciferase) sous le controle de la region regulatrice situee en 3’ du locus des genes des immunoglobulines (LCR 3’IgH) : les vecteurs pHEBo-pVH-Luc/Myc-LCR 3’IgH. La transfection du vecteur contenant c-Myc dans la lignee EREB2-5, dependante de l’œstrogene pour sa proliferation, a permis sa transformation en une lignee proliferante independante de cette hormone. En cela, il pourrait s’agir d’un nouvel outil moleculaire d’interet permettant d’etudier a la fois l’activite transcriptionnelle de LCR 3’IgH et le pouvoir transformant de c-Myc.
Isolation and characterization of a nitrite reductase gene and its use as a probe for denitrifying bacteria. [Pseudomonas stutzeri]

The dissimilatory nitrite reductase gene (nir) from denitrifying bacterium Pseudomonas stutzeri JM300 was isolated and sequenced. In agreement with recent sequence information from another strain P. Stutzeri (strain ZoBell), strain JM300 nir is the first gene in an operon and is followed immediately by a gene which codes for a tetraheme protein; 2.5 kb downstream from the nitrite reductase carboxyl terminus is the cytochrome c{sub 551} gene. P. stutzeri JM300 nir is 67% homologous to P. aeruginosa nir and 88% homologous to P. stutzeri ZoBell nir. Within the nitrite reductase promoter region is an fnr-like operator very similar to an operator upstream to a separate anaerobic pathway, that for arginine catabolism in P. aeruginosa. The denitrification genes in P. stutzeri thus may be under the same regulatory control as that found for other anaerobic pathways of pseudomonads. The authors have generated gene probes from restriction fragments within the nitrite reductase operon to evaluate their usefulness in ecology studies of denitrification. Probes generated from the carboxyl terminus region hybridized to denitrifying bacteria from five separate genera and did not cross-hybridize to any nondenitrifying bacteria among six genera tested. The denitrifier probes were successful in detecting denitrifying bacteria from samples such asmore » a bioreactor consortium, aquifer microcosms, and denitrifying toluene-degrading enrichments. The probes also were used to reveal restriction fragment length polymorphism patterns indicating the diversity of denitrifiers present in these mixed communities. « less
