The methods of biological species identification using nucleotide sequences of short genome regions (DNA markers) are actively developed. This principle formed the basis of the genetic database purposed the identification for all living organisms—Barcode of Life Data System (BOLD). In our study, we estimated the Internal transcribed spacer region (ITS)

Molecular characterization of Lathyrus species using chloroplast DNA trnH-psbA
Biochemical Systematics and Ecology, 2014Lathyrus L. is an important genus contributing in human food, animal feed and fodder. The genetic variation is studied among and within six species sampled over a large geographical area: Lathyrus cicera, Lathyrus sativus, Lathyrus sylvestris, Lathyrus tuberosus, Lathyrus ochrus and Lathyrus aphaca. The phylogenetic relationship among these species was

The ultrastructure of the psbA–trnH intergenic region (hereafter IGR) of the Cactaceae was characterised based on 642 sequences identifying a conserved region and a mutational hot spot with different evolutionary rates. The first section of the IGR includes a highly conserved 3′ UTR of the psbA containing a TATA-box and a stem-loop.

[The utility of trnH-psbA gene for phylogenetic analysis of Huperziaceae and plant barcoding].
Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2011The purpose of study was to discover the phylogenetic relations and plant barcoding of 17 plants from Huperziaceae.Phylogenetic tree of chloroplast trnH-psbA gene of 17 plants from Huperziaceae was constructed by software.It showed that Huperziaceae could be divided into two genera Huperzia and Phlegmariurus and bootstrap value reached 91%.Holub and ...

The genus Tanacetum L. consists of around 160 species of the Compositae-Anthemideae. It holds a crucial position for understanding the phylogeny of the tribe and its subtribal and generic classification. The present study focuses on the phylogenetic relationships of the species and aims at a discussion of the infrageneric classification and boundaries ...

Abstract Hybridization and polyploidization can be major mechanisms for plant evolution and speciation. Thus, the process of polyploidization and evolutionary history of polyploids is of widespread interest. The chloroplast DNA regions trnH-psbA was used to analyze to phylogenetic relationships and maternal donor of Elymus species and their closely ...

This paper presents the first molecular phylogeny of the genus Hemsleya using nuclear ITS and plastid trnH-psbA, rpl16, and trnL DNA sequences to examine the relationships among Hemsleya species. Phylogenetic relationships were elucidated using a combined analysis of all four datasets, however, the number of parsimony-informative characters was still ...
