Survey of Plant Pigments: Molecular and Environmental Determinants of Plant Colors
ACTA BIOLOGICA CRACOVIENSIA Series Botanica – ABSTRACTS (Vol. 51/1, 2009) ACTA BIOLOGICA CRACOVIENSIA Series Botanica 51/1: 7–16, 2009 SURVEY OF PLANT PIGMENTS: MOLECULAR AND ENVIRONMENTAL DETERMINANTS OF PLANT COLORS EWA MŁODZI ŃSKA* Department of Plant Physiology, Wroclaw University, ul. Kanonia 6/8, 50-328 Wrocław, Poland Received January 7, 2009; revision accepted February 20, 2009 * e-mail: [email protected] It is difficult to estimate the importance of plant pigments in plant biology. Chlorophylls are the most important pigments, as they are required for photosynthesis. Carotenoids are also necessary for their functions in photosynthesis. Other plant pigments such as flavonoids play a crucial role in the interaction between plants and animals as visual signals for pollination and seed scattering. Studies related to plant pigmentation are one of the oldest areas of work in plant science. The first publication about carotenoids appeared in the early nineteenth century, and the term "chlorophyll" was first used in 1818 (Davies, 2004). Since then, the biochemical structure of plant pigments has been revealed, as have the biosynthetic pathways for the major pigments that provide a useful variety of colors to blossoms and other plant organs. There is widespread interest in the application of molecular methods to improve our knowledge of gene regulation mechanisms and changes in plant pigment content. Genetic modification has been used to alter pigment production in transgenic plants. This review focuses on flower pigmentation, its biochemistry and biology. It presents a general overview of the major plant pigment groups as well as rarer plant dyes and their diversity and function in generating the range of colors observed in plants. -
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. -
Czech Forest (Site) Ecosystem Classification
Czech Forest (Site) Ecosystem Classification Jiří Viewegh 1 Introduction Ecosystem (site) classification of forests in Czech Republic is among those based on environmental factors. Initially, it was developed using a phytosociologal basis, but later, in view of operational application, the emphasis was placed on the environment of forest ecosystems. Climatic and soil studies helped to characterize environmental conditions and their relationships to forest communtieis. As the development of a true ecological classification is difficult, existing forest ecosystem classifications are driven either by vegetation or environment. These two different approaches influenced the development of forest classification (commonly referred to as forest typology) in former Czechoslovakia. "Typological System of Forest Management Planning Institute" is the name of a recently established forest site classification. Taking into consideration extensive changes in forest cover, which have resulted in profiound changes in forest communities and the associated forest floor and soil properties (degradation stages), the classification system is based upon relatively stable environmental conditions. In addition to characterizing humus forms and plant communities of climax (potential) vegetation, the systen also attempts to quantify potential production of forest ecosystems (e.g., yield class and canopy position of trees). This typological system, which was developed by Plíva and Průša (Plíva 1971-1976) has been applied in Czech forests since 1970. As the composition of most of the original forests was changed to Norway spruce (Picea abies) monocultures in last 200 years, two environmental (site) factors were used in organizing the system. These are soil and climatic properties, the latter are represented by forest vegetation zones which express altitudinal zonation of forest vegetation in Czech Republic. -

AB S TRACT : The phylogeographical structure of the European xerothermophilous grass species of Melica ciliata – M. transsilvanica complex (Poaceae) was assessed based on sequences of the non- coding trnL-trnF region of chloroplast DNA and AFLP data (obtained from the previous studies). Eleven haplotypes were detected within 88 populations collected from the entire distribution area. The clear geographic structure of cpDNA haplotypes was found. One main haplotype was wide- spread across Europe and was unique for all central and northern European population. The second high-frequency haplotype was distributed only on the Balkan Peninsula. In a marked contrast with non-variable more northerly populations, the greatest haplotype variation was revealed on the Iberian and Apennine Peninsulas, and somewhat smaller on the Balkan Peninsula, suggesting diversity centres and main glacial refugia in these regions. Among these southern refugia, probably mainly the Iberian Peninsula could have significantly contributed to postglacial re-colonisation of the more northerly parts of Europe. The some Apennine and Balkan lineages were clearly distinct and spread locally.

Duplications and Expression of DIVARICATA-Like Genes in Dipsacales
Duplications and Expression of DIVARICATA-Like Genes in Dipsacales Dianella G. Howarth* and Michael J. Donoghue *Department of Biological Sciences, St. John’s University, Queens, NY; and Department of Ecology and Evolutionary Biology, Yale University, New Haven, CT The genetics underlying flower symmetry shifts between radial and bilateral symmetry has been intensively studied in the model Antirrhinum majus. Understanding the conservation or diversification of this genetic pathway in other plants is of special interest in understanding angiosperm evolution and ecology. Evidence from Antirrhinum indicates that TCP and MYB transcription factors, especially CYCLOIDEA (CYC), DICHOTOMA (DICH), DIVARICATA (DIV), and RADIALIS (RAD) play a role in specifying dorsal identity (CYC, DICH, and RAD) and ventral identity (DIV) in the corolla and androecium of monosymmetric (bilateral) flowers. Previous data indicate that the ECE clade of TCP genes (including CYC and DICH) underwent two duplication events around the diversification of the core eudicots. In this study, we examined the duplication events within Dipsacales, which contains both radially and bilaterally symmetrical flowered species. Additionally, we report here the phylogenetic relationships of the DIV-like genes across core eudicots. Like TCP genes, we found three core eudicot clades of DIV-like genes, with duplications occurring around the diversification of the core eudicots, which we name DIV1, DIV2, and DIV3. The Antirrhinum genes, DIVARICATA and its sister DVL1, fall into the DIV1 clade. We also found additional duplications within these clades in Dipsacales. Specifically, the Caprifoliaceae (bilaterally symmetrical clade) duplicated independently in each of the three core eudicot DIV clades. Downloaded from Using reverse transcription polymerase chain reaction (rtPCR), we showed that most of these copies are expressed across floral tissues in the Dipsacales species Heptacodium miconioides. -

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. -

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.
