Karymorphological and Molecular Studies on Seven Species in Polygonoideae (Polygonaceae) in Egypt
Chromosome Botany (2012) 7: 17-22 © Copyright 2012 by the International Society of Chromosome Botany Karymorphological and molecular studies on seven species in Polygonoideae (Polygonaceae) in Egypt Magdy Hussein Abd El-Twab1, Ahmed M. Abdel-Hamid and Hagar Ata A. Mohamed Department of Botany and Microbiology, Faculty of Science, Minia University 61519, El-Minia City, Egypt 1Author for correspondence: ([email protected]) Received January 22, 2012; accepted February 29, 2012 ABSTRACT. Seven species in four genera of the Polygonoideae (Polygonaceae) in Egypt were subjected to karyomorphological and molecular studies in order to identify their chromosomal characteristics and investigate their phylogenetical relationships by the conventional staining method and the 5S rDNA PCR. Seed germination after treatment with low temperature stratifi cation and acidifi cation by concentrated H2SO4 was studied. Three rates of germination were obtained in response to the cold stratifi cation and acidifi cation: 1) High in Polygonum equisetiforme, Persicaria lanigera, Pe. lapathifolia and Pe. salicifolia; 2) low in Rumex dentatus; 3) no effect in R. pictus and Emex spinosa. Variation in the chromosome complements number, length and structure were detected for Po. equisetiforme (2n=58; new count); Pe. lanigera (2n=40; new count); Pe. lapathifolia (2n=22); Pe. salicifolia (2n=60); Emex spinosa (2n=18; a new count); Rumex dentatus (2n=40); and R. pictus (2n=18; a new count). Eighteen polymorphic bands of 5S rDNA were used to determine the similarities among the taxa with the similarity coeffi cient ranging between 0.2 and 0.67. KEYWORDS: Acidifi cation, Chromosomes, 5S rDNA, Polygonaceae, Stratifi cation. The Polygonaceae is cosmopolitic to temperate regions have been widely used to elucidate generic relationships (Täckholm 1974; Boulos 1999). -

DNA Barcoding of Commercialized Plants; an Examination of Amomum (Zingiberaceae) in South-East Asia

Hugo de Boer, Department of Organismal Biology, Systematic Biology, Uppsala University, Sweden. Dr. Hien Le Thu, Institute of Biotechnology (IBT), Vietnam Academy of Science and Technology (VAST), Hanoi, Vietnam. Abstract Trade and commercialization of non‐timber forest products, like cycas palms, rattans, and orchids form a serious threat to biodiversity in South‐East Asia. The intensity at which these resources are collected, as well as the techniques used, are unsustainable. To distinguish between common and endangered species is complicated, especially of related species within the same family or genus. Molecular barcoding applied to plants uses DNA‐sequences to contribute to identification and distinction between species. In this paper we investigate the possibility of finding suitable barcodes for Amomum Roxb., a genus of well‐known medicinal plants in South‐East Asia, by comparing three genetic markers matK, ITS and trnL.

The C4 Plant Lineages of Planet Earth

E-mail: [email protected] Received 30 November 2010; Revised 1 February 2011; Accepted 2 February 2011 Abstract Using isotopic screens, phylogenetic assessments, and 45 years of physiological data, it is now possible to identify most of the evolutionary lineages expressing the C4 photosynthetic pathway. Here, 62 recognizable lineages of C4 photosynthesis are listed. Thirty-six lineages (60%) occur in the eudicots. Monocots account for 26 lineages, with a Downloaded from minimum of 18 lineages being present in the grass family and six in the sedge family. Species exhibiting the C3–C4 intermediate type of photosynthesis correspond to 21 lineages. Of these, 9 are not immediately associated with any C4 lineage, indicating that they did not share common C3–C4 ancestors with C4 species and are instead an independent line. The geographic centre of origin for 47 of the lineages could be estimated. These centres tend to jxb.oxfordjournals.org cluster in areas corresponding to what are now arid to semi-arid regions of southwestern North America, south- central South America, central Asia, northeastern and southern Africa, and inland Australia. -

Faculty of Science and Technology, Universiti Kebangsaan Malaysia, 43600 Bangi, Selangor, Malaysia Email: [email protected] ABSTRACT Malaysia has initiated, produced and launched a National Policy on Biological Diversity in 1998 which contains policy statement, principles, objectives, rationales, strategies and above all action plans of programmes. The policy places great importance on taxonomy in realising the true dimension of biodiversity in the country and that taxonomy is a cornerstone of biodiversity has long been accepted and understood. Yet, many taxonomic institutions such as National Natural History Museum and National Herbarium are not within sight. Taxonomy is not prioritised within the R & D mechanism, capacity building is not undertaken with an accepted vigour, systematic research centres are not established, school and university curricula have not addressed taxonomic curricula, proper training of taxonomists and parataxonomists are not planned, and data management is not adequately placed either. Ironically the rate of ecosystem and habitat degradation and loss, species loss and genetic erosion are occurring at a rate unsurpassed in the past. Is there any crisis in Malaysian taxonomy and plant taxonomy in particular? The taxonomic community is small and aged. The reference collections are still small, the scientific productivity in term of publication of papers to report new species, new records, taxonomic revisions, phylogenetic relationships, variations, species loss and conservation efforts are still inadequate. The floristic treatments for the Tree Flora of Sabah and Sarawak and the Flora of Peninsular Malaysia are going-on. An attempt is made here to relate the richness of biodiversity to taxonomy so that the latter’s impediments could be properly addressed. -

Contents Introduction 1 Lao Flora Listed by Lao Script 13-121 Lao Flora Listed by Genus and Species 123-238 Introduction This introduction1 provides a brief synopsis of the forest habitats and ecoregions found in Lao PDR, as well as an overview of the related research on plant taxonomy. This is followed by a description of the structure and contents of the present volume and a citation of sources used to compile the present checklist. 1. Forest habitats and ecoregions in Lao PDR 1.1. Forest habitats Forest classifications can be vegetation-related (which implies that the factors used to distinguish forests are the physiognomic or floristic characteristics of the vegetation), biophysically- and climate-related (where broad environmental or geographic characteristics become the distinguishing factors), or management- related (which involves utilizing combinations of vegetation and non-vegetation criteria). These modes of classification are scale-specific: while global-scale classifications are largely based on climatic criteria such as rainfall and temperature, classification systems used at country- or smaller regional-level scales emphasise floristic and physiognomic characteristics as well as physical site factors (Wong, Delang, Schmidt-Vogt, 2007). These latter variables were taken into account by the National Office of Forest Inventory and Planning (NOFIP) when it classified the forests of Lao PDR (Manivong and Sandewall, 1992).
