Bulletin No. 6 Bulletin 6 of the European Dry Grassland Group Introduction During the last three months our organization has developed dynamically. We have invited Michael Vrahnakis to cooperate in the EDGG Executive Committee. The fourth EDGG sub-group has been established focussing on dry grassland biodiversity in Southern and Eastern Europe. The num- ber of members is gradually increasing and the number of involved coun- tries has reached 42. The preparation of the 7th European Dry Grassland Meeting is reaching completion and many of us will meet in May in Smo- lenice (Slovakia). In July, there will be an international EDGG research expedition in Central Podilia, Ukraine, which you can join. We invite you to read the details of our spring news included in this Bulletin issue. Ad- ditionally, you will find here three longer contributions: i) the results of floristic investigations on kurgans in the southern Ukraine, ii) a brief in- troduction to Mediterranean type ecosystems and iii) a survey of Greek grassland habitats. We wish you pleasant reading and a beautiful and successful growing season for 2010.

The main aims of the SEEDGG are (i) the establish- ment of a comprehensive database for dry grasslands; (ii) using the database for analyses of diversity pat- terns, large-scale consistent classifications and for conservation planning; (iii) building a platform for research activities for conservation of dry grasslands in SE Europe. The establishment of the joint data- base, the standardisation of header data and species lists, the compilation of existing data, and the regula- tion of data usage is coordinated by Steering Com- mittee of presently eight persons, supported by one or two representatives for each of the countries covered. We agreed to use Turboveg (Hennekens & Schamineé 2001) for the database. The header data will be unified for all countries and common species list for vascular plants, bryophytes, liverworts and lichens will be elaborated considering the most recent taxonomic solutions.

  • Polyploidy19 Program.Pdf
    Preface Yves Van de Peer The study of polyploidy dates back more than 100 years to the work of biologists such as Hugo de Vries and G. Ledyard Stebbins Jr. It has since then been realized that polyploidy is widespread and commonplace in plants. Although polyploidy is much rarer in animals, there are also numerous cases of currently polyploid insects, fishes, amphibians and reptiles. For a long time, ancient polyploidy events, dating back millions of years, were much less well documented and it was not until the advent of genomic technologies that conclusive evidence of ancient whole genome duplications (WGD) events became available and we now have evidence for tens, or even hundreds, of ancient WGD events. Explanations of the short-term success of polyploids are usually centered on the effects of genomic changes and increased genetic variation, which are mediated by changes in gene expression and epigenetic remodeling. Increased genetic variation, together with the direct cytogenetic conse- quences of genome doubling, can potentially affect the morphology and physiology of newly formed polyploids and could lead to alterations of ecologically and envi- ronmentally suitable conditions. For instance, it has repeatedly been proposed that polyploids have increased environmental robustness than do diploids, potentially leading to evolutionary advantages during periods of environmental turmoil. More- over, polyploidy has also sometimes been linked with higher diversification rates. Long(er)-term implications of WGD might be evolutionary innovation and increase in biological complexity by the biased retention of regulatory and developmental genes, which, given time, might diversify in function or cause rewiring of gene regulatory networks.

As a result of their direct plant-plant connections with their host plant, parasitic plants have special opportunities for horizontal gene transfer, the nonsexual transmission of genetic material across species boundaries. There is increasing evidence that parasitic plants have served as recipients and donors of horizontal gene transfer (HGT), but the long-term impacts of eukaryotic HGT in parasitic plants are largely unknown. Results: Here we show that a gene encoding albumin 1 KNOTTIN-like protein, closely related to the albumin 1 genes only known from papilionoid legumes, where they serve dual roles as food storage and insect toxin, was found in Phelipanche aegyptiaca and related parasitic species of family Orobanchaceae, and was likely acquired by a Phelipanche ancestor via HGT from a legume host based on phylogenetic analyses.

As a result of these direct plant-to-plant connections with their host plants, parasitic plants have unique opportunities for horizontal gene transfer (HGT), the nonsexual transmission of genetic material across species boundaries. There is increasing evidence that parasitic plants have served as the recipients and donors of HGT, but the long-term impacts of eukaryotic HGT in parasitic plants are largely unknown. Three parasitic plant genera from Orobanchaceae (Triphysaria versicolor, Striga hermonthica, and Orobanche aegyptiaca (syn. Phelipanche aegyptiaca)) were chosen for a massive transcriptome-sequencing project known as the Parasitic Plant Genome Project (PPGP). These species were chosen for two reasons.

In this study, the morphological features, current taxonomy, taxonomical history, and phylogenetic analysis based on rDNA Bayesian inference, as well as comparative analysis of ITS1 and ITS2 secondary structures, were investigated. It was found that A. borysthenicus is distant from A. onobrychis according to phylogenetic analysis. Moreover, A. borysthenicus has differences from the investigated taxa in its secondary structures of ITS1 and ITS2 transcripts. These data suggest that A. borysthenicus should be treated as a separate species rather than a synonym to A.

Plants steams can be used for animal grazing, in wind erosion control, to reduce water flow rates, and to increase evaporation and transpiration. In the NW of Iran (East Azerbaijan Province), rangelands previously used to animal grazing were changed to agricultural land use; this vegetation is unsuitable vegetation coverage. We studied Astragalus onobrychis to determine its stem biomass characteristics. Data were collected using an accidental sampling methodology (1*1 m). In total, 8 plots were identify and 40 samples were collected for this research. In the minimum, maximum and mean stem biomass for this plant were found to me 20.3, 51.2 and 31.5 g, respectively.
