Morphology of 2‐armed trichomes in relation to taxonomy: Malpighiales
Authors: Rao S. Raja Shanmukha , Sarma Vijayalakshmi
Published: August 2010

The structure, distribution and taxonomic importance of trichomes in the Malpighiaceae have been reported. The development of well known malpighian hair (unicellular 2‐armed T‐shaped hair) has been reported in detail. The trichome evidence clearly suggests that the Malpighiaceae appears to be closely placed to Vochysiaceae and Trigoniaceae rather than to the other Geraniales (sensu lato) and Polygalales and lends support for their placement in a separate ordinal rank Malpighiales (excluding Polygalaceae).
Osmoregulatory effect in some metabolites in response to salinity in Atriplex halimus var. schweinfurthii (Chenopodiaceae) With 4 Figures and one Table
Authors: Sadek L. A.
Published: August 2010

The present work was conducted to elucidate the biochemical adaptation, and revealed that some of the parameters used serve as good indicators of salinity tolerance and drought resistant in Atriplex halimus L. var. schweinfurthii which distributed in the Mediterranean desert of Egypt. The growth of these plants was not affected by salinity. The metabolic role in osmoregulation is achieved through the accumulation of minerals and proline. Salt stress stimulates the accumulation of all these metabolic products. These accumulation decreased rapidly in plants transferred back to control medium.

As suggested for other xerophytic species, it could be assumed that the high tolerance of A. halimus to salinity plays an important role in its ability to endure periods of drought. The role of mineral nutrients and proline accumulation in osmoregulation was discussed.
Juniperus SabinaLINNAEUS im Jura sowie deren Gesamtverbreitung, speziell im Bereich des europäischen Alpenbogens
Authors: Fuchs‐Eckert H. P.
Published: August 2010

Im Zusammenhang mit dem relativ reichen Vorkommen des Sade‐Baums im oberen Teil des Formazza‐Tals (Prov. Novara, Italien), das vom Autor seit mehr als 40 Jahren untersucht wird, hat es sich mittlerweile als notwendig ergeben, diese Lokalitäten in einem größeren phytogeographischen Kontext zu sehen. Besondere Aufmerksamkeit wurde dem einzigen Original‐Fundort im Jura‐Gebirge (Kanton Solothurn, Schweiz) und der Geschichte seiner Entdeckung gewidmet. Von Bedeutung ist ferner die Frage seines einheimischen sowie punktförmigen Vorkommens im allgemeinen und die Verbreitung des Taxons von der Iberischen Halbinsel bis in das östliche Zentralasien bei gleichzeitig detaillierterer Information über das Auftreten der Art im europäischen Alpenbogen zwischen den Seealpen im Westen zum Karst im Osten.
Electrophoretic analysis of the seed proteins of some species in genus Lotus With 4 Figures and one Table
Authors: Sammour R. H. , Hamoud M. A. , Haidar A. S. , Badr A.
Published: August 2010

The seed proteins of a number of accessions of L. corniculatus, L. creticus, L. halophilus, L. polyphyllos, and L. peregrinus were electrophoretically analysed on SDS‐PAGE. The majority of the seed proteins of these species is legumin‐like protein. Although each species showed a distinctive electrophoretic pattern, there was electrophoretic variations between the accessions of L. corniculatus, L. creticus and L. halophilus. These variations were discussed in terms of the morphological and cytological features. Cluster analysis showed that L. halophilus stand apart from the other species and L. creticus and L. polyphyllos are the closest one.

SEM studies of foliar epicuticular wax morphology in some taxa of Euphorbiaceae With one Table and 6 Plates
Authors: Kulshreshtha K. , Ahmed K. J.
Published: August 2010

The wax morphology of 16 species belonging to 13 genera of the family Euphorbiaceae have been studied by scanning electron microscopy. Six main types of wax, i.e., granular, crystalloid plates, ribbon, crust, rod‐shaped, and aggregate type, have been observed. The predominant types are fine granules and crystalloid plates. In several species, however, the wax is sparse or inconspicuous. The present study is not elucidate a clear pattern of relationships between wax morphology of Euphorbiaceae and its taxonomic divisions at sub‐family and tribal level made by some workers. However the studies indicates considerable diagnostic value of way morphological characters ad inter and intra‐generic level.
Habitat features and plant communities of the Holy places, Makkah, Saudi Arabia With 3 Figures and one Table
Authors: El‐Ghani M. M. Abd
Published: August 2010

The present study is an attempt to assess the effect of the environmental factors on the pattern and distribution of the plant communities in the Holy places area in Makkah, Saudi Arabia. Wide variation in topography and soil characteristics have a marked influence on the water resources and consequently on the vegetation. Eleven plant communities recognized by species dominance and habitat features have been distinguished. These include four communities dominated by trees and shrubs, five communities dominated by suffrutescent species and two are dominated by ephemerals. The floristic composition and the habitat features are described and the ecological relationships between the communities are briefly discussed.

Current situation of the raudha's woody plant populations in the Central Saudi Arabia With 3 Figures and 3 Tables
Authors: Shaltout K. H. , Mady M. A.
Published: August 2010

This study evaluates the size‐frequency distribution of six trees and shrubs (Tamarix aphylla, Ziziphus spina‐christi, Calotropis procera, Ricinus communis, Lagonychium farctum, and Lycium shawii) in two raudhas in the Central Saudi Arabia, in order to diagnose their current situation in relation to the prevailing environmental factors. The populations of five species had positively skewed size distributions which may represent rapidly growing populations with high reproductive capacity, and hence the long term stability. On the other hand, the population of Lycium shawii had a bell‐shaped distribution, therefore if its current situation continues, a reduction in its size is expected in the future. However, all the examined populations except those of Tamarix aphylla and Ziziphus spina‐christi seem to be under environmental stress.

Taxonomy of Phyllantheae: A chemical point of view
Authors: Hemalatha A. , Radhakrishnaiah M.
Published: August 2010

The distribution pattern of phenolic acids in 12 species of Phyllantheae is studied. The chemical data show a similarity between Flueggea microcarpa and the species of Phyllanthus. F. microcarpa and F. leucopyrus appear to be conspecific, but they are chemically different. The treatment of Bridelia and Cleistanthus in one group to the exclusion of Glochidion is supported.
Floral anatomy and systematic position of Flindersia R. BR
Authors: Lal Sheela , Narayana L. L.
Published: August 2010

The floral anatomy of Flindersia australis, F. bourjotiana, F. dissosperma and F. schottiana, has been studied. The flower is bisexual, regular, 5‐merous, 5‐cyclic and hypogynous. The sepals are 3‐traced and lateral traces of adjascent sepals arise conjointly. The petals are single traced. There is adnation between the petal midribs and antipetalous staminodal traces. The androecium in Flindersia consists of five fertile stamens and five vascularised staminodes. The massive and annular disc is non‐vascularised and is present between the androecium and gynoecium. The ovary is 5‐carpellary, syncarpous and 5‐locular. The carpels are 3‐traced. Dorsal carpellary traces are suppressed. Judging from the position of the homocarpellary ventrals, the placentation is interpreted as axile. The style is vascularised by the homocarpellary ventrals and terminates in five conduplicate stigmas. It is tentatively suggested that Flindersia along with Chloroxylon can be segregated into an independent family, Flindersiaceae and the family can be considered as a connecting link between Meliaceae and Rutaceae.

A phytogeographical comparison between subalpine forests of Guatemala and Costa Rica
Authors: Islebe G. A. , Kappelle M.
Published: August 2010

We conducted a comparative study on the phytogeographical similarities between the vascular generic floras of subalpine forests in Guatemala and Costa Rica. In total 178 vascular plant genera in 80 families were recorded in Central American subalpine forests, with 103 in Guatemala and 127 in Costa Rica. Woody genera account for less than 30% in subalpine Guatemala and over 50% in subalpine Costa Rica. The Guatemalan subalpine flora consists mainly of wide temperate, holarctic and neotropical herb genera, whereas the Costa Rican subalpine flora is principally made up of neotropical shrub and wide tropical tree genera, next to a small amount of wide temperate herb genera. Almost 30% of the 178 vascular genera are shared between both Central American subalpine floras, resulting in a Sørensen Coefficient of Community of 45%. The major part of the shared flora (57%) is temperate in distribution, the holarctic element being twice as important as the austral‐antarctic element. In conclusion, we state that since the formation of the Panamanian Isthmus plant migration from the holarctic region into subalpine Costa Rica dominated over migration from the austral‐antarctic region towards subalpine Guatemala.
Micromorphological studies of original and mutant cultivars of ornamentals
Authors: Datta S. K. , Shome U.
Published: August 2010

Four original Chrysanthemum, two Rose cultivars and Lantana depressa and their respective gamma ray induced flower colour/chlorophyll variegated mutants were selected for the study of micromorphology of petal/leaf surfaces. Differences were observed among the original and mutant cultivars in cell shape, cell boundaries, cell wall surface and striations. The observations revealed a lot of finer details of petal surface, not only among the original and mutant cultivars but also between the cultivars. Studies clearly indicated that petal micromorphological characters can be utilized not only for identifying the mutants but also a comparative study will help the proper identification of different present day cultivars of Chrysanthemum and Rose and their origin.

Neben morphologischen Untersuchungen werden auch die Verbreitung und Ausbreitung innerhalb Europas beschrieben und kurz diskutiert.
Effect of cement dust on petal morphology of Brassica campestris L
Authors: Misra J. , Pandey V. , Ahmad K. J.
Published: August 2010

Effect of cement dust on petal morphology of Brassica campestris L. was studied under light and scanning electron microscopes. In control (undusted) plants, papillae were striate and coronulate with clear boundaries unlike dusted plants where they were shrunken and collapsed. Number of papillae was also reduced. Cement dust absorbed moisture from petal surface causing water loss and subsequent loosening of the arrangement of papillae. Damage to flower petals will affect the quality of flowers thus causing serious losses in floriculture.
Notes on the Oak‐hornbeam forest communities of the Czech Republic
Authors: Neuhäuslová Z. , Kolbek J.
Published: August 2010

By the revision of the phytocenological material from the oak‐hornbeam forests a new subassociation. Melampyro‐Carpinetum vincetoxicetosum, has been distinguished. It is linked‐up to the warmer and steeper slopes with mesotropic brown earths in the hilly countries of the Czech Republic. This community is compared with the related subassociations Melampy‐ro‐Carpinetum festucetosum heterophyllae (KLIKA 1939) NEUHÄUSL 1982 and Melampyro‐Carpinetum primuletosum veris (MIKYŠKA 1963) NEUHÄUSL 1982. The new unit is documented by phytocenological releves and synecological characteristics.
The desert vegetation communities of the Lower Volga Valley
Authors: Golub V. B.
Published: August 2010

The present paper is a continuation of a set of investigations aimed at description of the Lower Volga valley vegetation (GOLUB and MIRKIN 1986; GOLUB and ČORBADZE 1989; GOLUB et al. 1991). The paper covers desert vegetation communities formed on ecotopes which are not or unimportantly affected by floods and ground waters. Two new classes have been determined i.e. Artemisietea lerchianae (communities on loamy‐sandy and loamy soils) and Artemisietea tschernievianae (communities on sandy soils). Floristic composition syntaxa of lower rank is dependent on pasture load intensity, sod deterioration degree and height of ecotopes position above a lower water level of the water streams.
Pollen morphology of Cicer L. ‐ wild and cultivated annual species
Authors: Chaturvedi M. , Yunus D. , Datta K.
Published: August 2010

Pollen morphological studies have been carried out in all the annual species of Cicer L. including four varieties of the cultivated species C. arietinum, using LM and SEM. Pollen grains are 3‐zonocolporate with large lolongate endocolpia in C. arietinum, C. cuneatum, C. judaicum, C. pinnatifidum, C. reticulatum and C. yamashitae, and 3‐parasyncolporate in C. bijugum, C. chorassanicum and C. echinospermum. Exine surface ornamentation in these species is reticulate, fossulatereticulate or pitted at the mesocolpium. In case of reticulate exine surface, the number of lumina/cm2 counted at the mesocolpium has been used as an additional parameter for delineating the species. A pollen morphological similarity between the wild species C. reticulatum and the cultivated species C. arietinum with respect to apertural feature and exine surface ornamentation supports the view of LADIZINSKY and ADLER (1976a, b), that the former species could be the possible wild progenitor of the cultivated chickpea.
Monerma P. BEAUV. (Poaceae) – not an illegitimate name
Authors: Scholz H.
Published: August 2010

The two names Hainardia and H. cylindrica proposed in 1967 for the widely distributed Mediterranean taxa so far known under Monerma and M. cylindrica are to reject as illegitimate in favour of the latter names, both legitimate, well‐established and used in taxonomic literature. Some modern trends intending the protection of illegitimate names are critically reflected in brief.

An analysis of the early floral development of Pittosporum tobira (THUNB.) AITON and some remarks on the systematic position of the family Pittosporaceae
Authors: Erbar C. , Leins P.
Published: August 2010

In Pittosporum tobira all floral organs are initiated in a strictly acropetal succession. It is striking that sepals and petals show an extremely early hyponastical development. Important floral characters for placing the family Pittosporaceae near the Apiales (Araliaceae and Apiaceae) are the early sympetaly, only gradual differences in the gynoecium development and placentation, and the fact that a nectar secreting area is situated at the base of the dorsal carpel flanks (ovary superior in Pittosporaceae, inferior in Apiales).

Viscid latex, which plays an important role in the dispersal of the seeds by exozoochory, is produced by the multicellular epidermal hairs in the septal (placental) region.
Die morphologische Vielfalt der generativen Diasporen – Präsentation eines Lehr‐ und Lernschemas

Published: August 2010

In einem vor allem für Lehr‐ und Lernzwecke gedachten Schema wird in zweidimensionaler tabellarischer Form ein Überblick über die strukturellen Möglichkeiten der Angiospermen gegeben, generative Diasporen zu bilden. Berücksichtigt werden die Merkmale Gynoeceumstyp/Diasporentyp/Perikarpanatomie. Dabei sind die Diasporen (mit Spring‐/Streu‐ und Schließfrüchten) gegen die morphologischen Gestaltungsmöglichkeiten des Gynoeceums (chori‐/coenokarp und ober‐/unterständig) aufgetragen. Die Tabelle zeigt, wie die Angiospermen in der Lage sind, aus unterschiedlichen Teilen des Gynoeceums und der Blüte sowie Blütenständen gleiche Funktionstypen zu erzeugen. Nicht berücksichtigt werden die Ausbreitungsweisen, die in der tabellarischen Darstellungsweise den morphologischen Möglichkeiten in der dritten Dimension überlagert wären. Nur sehr wenige Gestaltungsmöglichkeiten finden keine Entsprechung.
Spergulo morisonii–Corynephoretum canescentis (Frühlingsspark‐Silbergrasflur) – Lebensstrategien von Binnendünen‐ und Lockersandbesiedlern
Authors: Frey W. , Hensen I.
Published: August 2010

Im Spergulo morisonii‐Corynephoretum canescentis (Frühlingsspark‐Silbergrasflur; Typische Variante undCladonia‐Variante) sind drei Lebensstrategien von biologischer Relevanz: die der Einjährigen Pendler, die der Besiedler mit Fern‐ und Nahausbreitung und die der Chamaephytischen Ausdauernden mit Fern‐und Nahausbreitung.

Bei den Einjährigen Pendlern tritt die übersandungsunempfindliche AssoziationskennartSpergula morisonii, die Nahausbreitung mit generativen Diasporen aufweist und eine mächtige Diasporenbank aufbaut, bestimmend auf. Bei den Besiedlern bedingen vor allem das SilbergrasCorynephorus canescensund die LaubmoosePolytrichum piliferumundCeratodon purpureusdie hohen Gruppenmengenanteile, bei den Chamaephytischen Ausdauernden sind es die strauchigen FlechtenCetraria aculeataundCladoniauncialis. Diese Arten zeigen ein ausgeprägtes klonales Wachstum und Reproduktionsverhalten. Hierdurch vermögen sich die Arten effektiv auszubreiten und zu regenerieren.

Die beiden Varianten unterscheiden sich durch die Anteile Besiedler/Chamaephytische Ausdauernde. In der Typischen Variante dominieren die Besiedler (BFNg,kl) mitCorynephorus canescens, in derCladonia‐Variante treten die Chamaephytischen Ausdauernden (ChAFNkl) in den Vordergrund. Dies ist auf die stabileren Oberflächenverhältnisse zurückzuführen.

Published: August 2010

On the basis of extensive fieldwork, a first survey of carnivorous plants occurring on inselbergs is provided. Inselbergs are mostly dome‐shaped granitic or gneissic outcrops with scarce vegetation cover. They are important habitats for carnivorous plants in wooded tropical areas. Three families of carnivorous plants (Droseraceae, Lentibulariaceae, Nepenthaceae), including four genera and 45 species are reported from various inselberg habitats. Carnivorous plant families and genera are represented on inselbergs proportionally to their importance in the regional species pool.
On the genera Hammatolobium FENZL and Tripodion MEDIK. (Papilionaceae, Loteae s. 1.)
Authors: Tikhomirov V. N. , Sokoloff D. D.
Published: August 2010

The comparative analysis of the morphological features in Tripodion and Hammatolobium shows that they cannot be treated as members of the same genus. Tripodion tetraphyllum and Hammatolobium are considered to differ from each other in both of the features used by LASSEN (1986) to distinguish the genera Tripodion s. l. (incl. Hammatolobium) and Anthyllis s. str. T. tetraphyllum has dehiscent and not lomentaceous fruits and differs in this important character from Hammatolobium as well as from Anthyllis s. str. The standards of Hammatolobium lotoides and H. kremerianum differ from the standard of T. tetraphyllum and resemble the ones of certain species of Anthyllis. Two subgenera of Hammatolobium are accepted.

Revisionula incompleta Ornithogalorum Austro‐Africanorum (Hyacinthaceae)
Authors: Müller‐Doblies Ute , Müller‐Doblies Dietrich
Published: August 2010

For the well advanced Flora of Namaqualand edited by A. LE ROUX a state of the art list of accepted Ornithogalum names, recently the second genus in size among southern African Hyacinthaceae (after Lachenalia) and now the largest one, is needed. The present sketchy revision is the preliminary harvest of 20 years of occasional encounters with this genus in the field and subsequent observations on cultivated plants, which could solve quite a number of questions and the preliminary lumping of taxa in the last revision (OBERMEYER 1978).

The present treatment is intended to be an addition to OBERMEYER'S revision. Its backbone is the enlarged species list. Synonyms are only repeated if there are corrections or additions concerning further type specimens. The keys are still based on OBERMEYER'S.

In the recent Ornithogalum list for southern Africa by REID 1993 only four species are added to OBERMEYER'S revision. One of these additions is reduced to synonymy in the present paper, whereas all the 54 species recognized by OBERMEYER 1978 are tentatively maintained. Additionally 26 species are resuscitated from synonymy and 40 new species are described, mainly from the winter‐rainfall region (western Cape and southern Namibia). Thus with a total of 123 southern African species Ornithogalum is again the largest genus of Hyacinthaceae in southern Africa. More details about differences with OBERMEYER'S treatment concerning name changes, resuscitations, and the infrageneric taxonomy proposed are presented in a detailed summary at the end of the paper.

In order to place correctly a synonym excluded from Ornithogalum, the genus Physodia SALISB. 1866 is resuscitated, and four new specific combinations are proposed.
Psammophora and other sand‐coated plants from southern Africa
Authors: Neinhuis Christoph , Müller‐Doblies Ute , Müller‐Doblies Dietrich
Published: August 2010

Whereas Psammophora is well known as a sand‐bearing plant since its description (DINTER & SCHWANTES 1926), although not yet enough studied, such behaviour has hitherto not been reported of Monocotyledons. In this class, however, psammophory is no rare event, as is shown by a list of about 30 species out of the following families and genera of the superorder Liliiflorae: Asphodelaceae (Trachyandra divaricata), Anthericaceae (Chlorophytum viscosum), Hyacinthaceae (14 Albuca spp., two Dipcadi spp., five Ornithogalum spp.), Amaryllidaceae (Bokkeveldia watermeyeri with two subsp., Brunsvigia cf. bosmaniae, two Strumaria spp., both Namaquanula spp.), and Iridaceae (one sp.). In this paper the topography of the secretion on the epiderm is investigated by SEM. A smooth epiderm may be covered evenly with secretion, mostly, however, we find a localization of the secretion: it is confined to ribs and/or papillae or glandular hairs. Chemically the secretion, which is as clear as water and brittle when dry, consists probably of polysaccharids, which are very slowly soluble in water. In a young stage of the leaves the secretion is sticky and viscous, as to allow the sinking of small particles. As to the function mimesis, protection against being eaten away and against high insolation, or against abrasion by sandy winds are discussed.

Published: August 2010

Summary

The first escapes of Giant hogweed were recorded already in the middle of the 19th century, whereas the still active exponential spread began about the sixties of this century. As in other neophytes this progress is promoted by strong modification of habitats by man. According to germination experiments and investigations of the soil seedbank the high reproduction rate of Giant hogweed plays an important role, too. The actual distribution in Germany is shown on a map.

Spatial distribution characteristics of glacial relief flora of the high mountains of the Caucasu
Authors: Shetekauri Sh.
Published: August 2010

The role of the glacial relief of the Caucasus in the spatial distribution of high‐mountain flora was the subject of investigation. It was established that different types of relief forms (moraine, glacial trough, cirque) represent the environments for refuges of endemic and floristic elements. Glacialinterglacial effects exert essential influence on the development of peculiarities of vertical flora distribution‐location and also on the arrangement of different rich floristic centres.
Die Wurzelsysteme der endemischen Echium‐Arten auf Tenerife (Kanarische Inseln) und ihre Beziehungen zum Wuchsort
Authors: Werner M. , Lüpnitz D.
Published: August 2010

Die Wurzelsysteme der tenerfenischen Echium‐Arten entwickeln sich recht uneinheitlich, immer aber gemäß den örtlichen Gegebenheiten wie Bodenstruktur, Tiefgründigkeit, Wasserführung und entsprechend dem artspezifischen Bauplan. Die meisten Arten sind weder ausgeprägt flach‐ noch tiefwurzelnd. Sie besitzen aber in der Mehrzahl eine Hauptwurzel, die nur dort pfahlartig in die Tiefe wächst, wo der Untergrund es zuläßt. Die Existenz feuchterer „Taschen”︁, nach denen sich das Wurzelwachstum ausrichtet, sind die wichtigste Wasserquelle für die Mehrzahl der Echium‐Arten. Sie bewirken eine beträchtliche Variabilität ihrer Wurzelsysteme. Eine günstige Wasserversorgung bieten auch Felsspalten und ‐klüfte. E. simplex und E. giganteum haben sich auf die Erschließung solcher Standorte spezialisiert. E. auberianum ist der einzige Gattungsvertreter mit einem ausgeprägt flach streichenden Wurzelsystem, was in engem Zusammenhang mit dem Bodenwasserhaushalt des von ihm besiedelten losen Bimssteins steht.
Reproductive ecology of Mimosa pigra L. in Egypt
Authors: Sheded M. G. , Hassan L.
Published: August 2010

Mimosa pigra L. is a rare shrub restricted to the Nile banks and granite islands of Aswan. It is considered one of the endangered species in Egypt (EL‐HADIDI et al. 1992). Maximum germination percentage (100%) was obtained after pretreating the seeds with mechanical scarification. Optimum temperature for seed germination was 35 °C. The germination and growth of radicle and plumule of Mimosa pigra L. responded to matric potential. The germination and seedling growth declined rapidly with the reduction of matric potential. Seed bank, seed rain, seed dispersal and seedling establishment were examined and discussed. The study recommends maintaining of Mimosa pigra population in situ for conservation and conducting experimental research in situ and ex situ on its propagation.
On the occurrence of an additional diploid taxon — Withania obtusifolia TÄCKH. (Solanaceae) — from the natural population of South India
Authors: Sundari G. Thirupur , Sudhakaran S. , Ganapathi A.
Published: August 2010

The genus Withania (Solanaceae) — which is widely known as “Aswagantha” in Ayurvedha — is useful in the diagnosis of tuberculosis to arthritis. It is known as “Indian ginseng”. It has a world‐wide distribution with ten species. Earlier taxonomists recorded a single species (tetraploid) Withania somnifera DUNAL from the natural populations of South India. Extensive field survey and critical perusal of literature revealed the presence of an additional diploid taxon of Withania (Withania obtusifolia TÄCKH.) from the natural populations. The present paper is aimed to describe the morphological and cytogenetic variations exhibited by the two taxa of Withania with the aid of biosystematic studies.
On the status of Diphasiastrum oellgaardii (Lycopodiaceae, Pteridophyta)
Authors: Vogel J. C. , Rumsey F. J.
Published: August 2010

In a recent publication HORN (1997: 9) enthusiastically states that with the study by STOOR et al. (1996), which he co‐authored, “the biosystematics of Diphasiastrum in Europe has finally been resolved”. These authors present a scheme showing six taxa, three basal taxa (Ausgangsarten) and three taxa of hybrid origin in a triangular form to illustrate the relationships of European Diphasiastrum and they include a new taxon of hybrid origin, D. oellgaardii. The evidence for the origin and identity of D. oellgaardii is based solely on molecular data derived from allozyme electrophoresis. The interpretation of the allozyme data presented by the authors is open to dispute. The analysis of their data appears to be incorrect as STOOR et al. (1996) misapply the concept of additive banding patterns and fixed heterozygosity to homoploid hybrid taxa. Furthermore, the photograph in STOOR et al. (1996) of D. oellgaardii at its type locality resembles a growth form of D. alpinum frequent in the British Isles. In the light of these concerns we recommend caution and suggest that this name should not be adopted for individuals apparently intermediate between D. alpinum and D. tristachyum until further research is presented.

Embryology of Phryma leptostachya L. (Verbenaceae) with considerations of its systematic status and affinities
Authors: Ramana R. Venkata , Rao P. S. Prakasa , Dutt B. S. M. , Narayana L. L.
Published: August 2010

Some embryological aspects – structure and development of the microsporangium, microporogenesis and male gametophytes; embryogeny and some features of seed‐coat of Phryma leptostacha L. have been studied. The microsporangial wall develops confirming to the Dicot type of Davis (1966). The anther tapetum is secretory and displays dual origin. Endothecial cells exhibit fibrous thickenings. The tricolpate pollen grains are shed at 3‐celled stage. The embryogeny follows the Hyoscamus variation of the Solanad type (Johansen 1950) or the Period‐I, Series C, Megarchetype IV of Soueges (1948). The mature embryo is dicotyledonous. Only a papery layer of endosperm encompasses the embryo. In the light of the present study with the other relevant informations from diverse sources the taxonomic status of the taxon Phryma leptostachya L. is examined. It is suggested, that this genus is undoubtedly related to some verbenaceous taxa and so merits to be retained in a separate tribe (Phrymeae) of its own nearer but not within the sub‐family Verbenioideae, a view expressed by Thorne (1976, 1983, 1992) and Takhtajan (1980, 1987).

Applying high‐throughput Top‐Down MS to an entire proteome requires a yet‐to‐be‐established model for data processing. Since Top‐Down is becoming possible on a large scale, we report our latest software pipeline dedicated to capturing the full value of intact protein data in automated fashion. For intact mass detection, we combine algorithms for processing MS1 data from both isotopically resolved (FT) and charge‐state resolved (ion trap) LC‐MS data, which are then linked to their fragment ions for database searching using ProSight. Automated determination of human keratin and tubulin isoforms is one result. Optimized for the intricacies of whole proteins, new software modules visualize proteome‐scale data based on the LC retention time and intensity of intact masses and enable selective detection of PTMs to automatically screen for acetylation, phosphorylation, and methylation. Software functionality was demonstrated using comparative LC‐MS data from yeast strains in addition to human cells undergoing chemical stress. We further these advances as a key aspect of realizing Top‐Down MS on a proteomic scale.
Top‐down protein characterization facilitated by ion/ion reactions on a quadrupole/time of flight platform
Authors: Huang Teng‐yi , McLuckey Scott A.
Published: August 2010

In comparison to bottom‐up proteomics approaches, whereby peptides derived from proteolytic digestion are analyzed, top‐down approaches, involving direct analysis of intact proteins, provide higher specificity for protein identification and are better‐suited for the characterization of sequence variants. However, top‐down protein characterization usually requires more sophisticated instrumentation and methodologies to deal with the more complex tandem mass spectra derived from dissociation of high mass multiply charged intact proteins. Gas‐phase ion/ion reactions are universally applicable and have proved to be useful in mixture analysis and top‐down biomolecule characterization. The coupling of the ion/ion proton transfer reaction in the context of MS/MS has been demonstrated to expand informing power in top‐down protein characterization, particularly with platforms that employ electrodynamic ion trap and TOF mass analysis. In addition, probing protein primary structure using ion/ion electron transfer dissociation usually provides extensive structurally informative fragmentation and also allows for the localization of labile PTMs. Here, the performance of the widely used quadrupole/TOF platform, equipped with ion/ion reaction functionality, for top‐down protein characterization is summarized, and various methodologies employing ion/ion reactions are reviewed.
Three‐dimensional models of arteries constructed using multidetector‐row CT images to perform pancreatoduodenectomy safely following dissection of the inferior pancreaticoduodenal artery

Background/purpose

During a pancreatoduodenectomy (PD) it is important that the anatomy of the arcade of blood vessels in the head of the pancreas is fully understood before the surgery in order to reduce intraoperative bleeding. In most of the patients our group has treated, the inferior pancreaticoduodenal artery (IPDA), one of the efferent arteries of the head of the pancreas, has formed a short common trunk with the first jejunal artery (FJA). Thus, by first locating the origin of the FJA, it was easier to locate the IPDA. There are two ways to locate the IPDA: (1) by measuring the distance between the origin of the superior mesenteric artery (SMA) and that of the FJA; (2) by measuring the distance between the origin of the middle colic artery (MCA) and that of the FJA. Here, we report our measurements of both distances using three‐dimensional (3D) models of arteries constructed with multidetector‐row computed tomography (MD‐CT) images and discuss which is the better measurement to determine the location of the IPDA during PD.

Methods

A total of 140 patients underwent 64‐MD‐CT imaging to acquire early and late arterial phase scans. The distance between the origin of the SMA and that of the FJA and the distance between the origin of the MCA and that of the FJA origin were measured.

Results

In patients whose IPDA formed either a common trunk with the FJA or arose directly from the SMA, the IPDA or the common truck was located in parallel with the SMA at a very short distance of approximately 18 mm from the MCA origin towards the center. The distance between the SMA origin and the IPDA was significantly longer (approximately 36 mm). Therefore, locating the MCA origin during PD helped determine the location of the IPDA. However, in patients whose anterior inferior pancreaticoduodenal artery (AIPDA) and posterior inferior pancreaticoduodenal artery (PIPDA) arose separately, the distance between the AIPDA origin and the MCA origin was approximately 18 mm, the distance between the AIPDA origin and the PIPDA origin was approximately 19 mm, and the distance between the PIPDA origin and the SMA origin was 19 mm. Thus, locating the SMA helped determine the location of the IPDA during PD in these patients.

Conclusion

Based on our findings that the distance between the IPDA origin and the MCA origin was short, we have shown that it is effective to locate the MCA origin in order to determine the location of the IPDA.
