1 This paper has also appeared in the proceedings of the LSK International Conference held in Seoul, Korea, in August 2002, and has been revised. I thank the audience at the LSK conference for their feedback on the earlier version. 2 I would like to thank Arto Anttila, Vivienne Fong, K.P. Mohanan, and my supervisor Tara Mohanan for their valuable comments and suggestions on an earlier version o...

MaturaseK gene (matK) of chloroplast is highly conserved in plant systematics which is involved in Group-II intron splicing. The size of the gene is approximately 1500 base pairs in length, located with in the intron of trnK. In the present study, matK gene from Cucurbitaceae was taken for the analysis of variants, parsimony site, patterns, transition/ transversion rate and phylogeny. The famil...

background: more than 60 species of the genus lathyrus are distributed in southwest asia. it is the second largest genus of the tribe fabeae, after vicia, in the region (and in iran with 23 species). in the regional flora (flora of turkey, florairanicaand flora of iran), the genus has been divided into 9-10 sections. here we analyzed the phylogeny of lathyrus and its relationship with pisum bas...

DNA barcoding is a tool for species identification. For plant species identification, two of plastid genes (rbcL and matK) were used as standard barcodes. There are limitations of each gene marker but matK is considered to be the closest plant analogue to the CO1 animal barcode. As a mega-biodiversity country, Indonesia has many plant species used for ornamental and/or medical purposes. This st...

A DNA barcode is a DNA fragment used to identify species. For land plants, DNA fragments of plastid genome could be the primary consideration. Unfortunately, most of the plastid candidate barcodes lack species-level resolution. The identification of DNA barcodes of high resolution at species level is critical to the success of DNA barcoding in plants. We searched the available plastid genomes f...

صخلملا Seasonal variation of zooplankton biomass has been carried out at two selected sites on Greater Zab River. Monthly samples of water were collected during period from January to December 2008. Some physico-chemical properties of water were studied including water temperature (from 8 to 30.5 C), hydrogen ion concentration (from 6.3 to 8), EC (from 255 to 821 μs.cm), turbidity (1085 NTU), d...

DNA barcoding of United Arab Emirates (UAE) native plants is of high practical and scientific value as the plants adapt to very harsh environmental conditions that challenge their identification. Fifty-one plant species belonged to 22 families, 2 monocots, and 20 eudicots; a maximum number of species being legumes and grasses were collected. To authenticate the morphological identification of t...

DNA barcodes have been increasingly used in authentication of medicinal plants, while their wide application in materia medica is limited in their accuracy due to incomplete sampling of species and absence of identification for materia medica. In this study, 95 leaf accessions of 23 species (including one variety) and materia medica of three Pharmacopoeia-recorded species of Angelica in China w...

BACKGROUND AND AIMS The popular hybrid orchid Vanda Miss Joaquim was made Singapore's national flower in 1981. It was originally described in the Gardeners' Chronicle in 1893, as a cross between Vanda hookeriana and Vanda teres. However, no record had been kept as to which parent contributed the pollen. This study was conducted using DNA barcoding techniques to determine the pod parent of V. Mi...
