    DNA-Barcoding of Some Medicinal Plant Species in Saudi Arabia Using rbcL and matK Genes

    Abdulrahman Alasmari*

    Phyton-International Journal of Experimental Botany, Vol.89, No.4, pp. 1059-1081, 2020, DOI:10.32604/phyton.2020.010952

    Abstract In the Kingdom of Saudi Arabia (KSA), thousands of plants are considered to have therapeutic value. The ambiguous use of identification mainly morphological characteristics of many plants has resulted in the adulteration and displacement of plant products which undermine their therapeutic value and weak documentation of plant resources. The aims of this study were therefore to evaluate genetic variability and explore the phylogeographic architecture for Saudi medicinal plant samples using rbcL and matK genes as barcodes for genomic identification. The matK and rbcL sequences collected for these samples were used as key markers for examining the relationship between Saudi medicinal… More >

    Morphology and Genetic Studies of Cymodocea Seagrass Genus in Tunisian Coasts

    Ramzi Bchir1,2,*, Aslam Sami Djellouli1, Nadia Zitouna3, Didier Aurelle4, Gerard Pergent2, Christine Pergent-Martini2 and Habib Langar1

    Phyton-International Journal of Experimental Botany, Vol.88, No.2, pp. 171-184, 2019, DOI:10.32604/phyton.2019.05261

    Abstract Specimens of Cymodocea (Viridiplantae, Magnoliophyta) collected on the Tunisian coasts showed a particular morphological and anatomical difference with the classical descriptions of Cymodocea nodosa (Ucria) Asch. the only species of this genus reported in the Mediterranean Sea. In order to precise the taxonomic identity of the new specimens we aimed in this work (i) to verify the identity of the new forms, (ii) to evaluate the genetic diversity of the population, (iii) to test the validity of the existing identification keys of the Tunisian Cymodocea populations. Four stations located in two regions of the Tunisian coasts were sampled. Leaf morphological… More >
