Phylogenetic relationships betweenLeymus(Poaceae, Triticeae) and related diploid Triticeae species based on isozyme and genome-specific random amplified polymorphic DNA (RAPD) markers

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology (2011)

Abstract To investigate the phylogenetic relationships between Leymus and related diploid species of the Triticeae tribe, the esterase isozyme (EST), superoxide dismutase (SOD) isozymes, and genome-specific random amplified polymorphic DNA (RAPD) markers were used to analyze for 14 Leymus species, together with two Psathyrostachys species (Ns), three Pseudoroegneria species (St), two Hordeum species (H), Lophopyrum elongatum (Ee), Australopyrum retrofractum (W), and Agropyron cristatum (P). The data were used to construct dendrograms by means of UPGMA in the NTSYS-pc computer program. The results suggested that (1) isozyme analysis can be used in the systematic studies of these perennial Triticeae; (2) there is a close relationship between Leymus, Psathyrostachys juncea, three Pseudoroegneria species, and Lophopyrum elongatum; (3) the Ns genome-specific RAPD marker was present in all 14 polyploid species of Leymus, while the Ee and P genome-specific RAPD markers were absent in 14 polyploid species of Leymus; the St, W and H genome-specific RAPD markers were present in some species of Leymus; (4) Leymus species have multiple origins, and different Leymus species derived their genomes from different donors.

Relationships among six medicinal species of Curcuma assessed by RAPD markers

Journal of Medicinal Plants Research (2011)

Xue-Mei Zou Zhuojun Dai Chunbang Ding Li Zhang Yonghong Zhou

The random amplified polymorphic DNA (RAPD) markers were applied to detect the genetic relationships and diversity among 33 accessions of Curcuma species in China, which involved six medicinal species. A total of 115 products were amplified by 21 primers, among which 106 products (92.17%) were found to be polymorphic. 3 to 8 polymorphic bands were amplified by each polymorphic primer, with an average of 5.48 bands. The data of 115 RAPD bands were used to generate Jaccard’s similarity coefficients and to construct a dendrogram by means of UPGMA. The results show that the genetic similarity coefficient relatively of these six species is large, from the cluster diagram, the genetic relationships are not associated with their geographical distributions. Key words: Curcuma, cluster analysis, genetic diversity, random amplified polymorphic DNA, similarity coefficient.
