Abstract:
OBJECTIVETo investigate 4 populations of 80 samples of Vitex trifolia var. simplicifolia collected from Shandong and Jiangxi province and analyze their intraspecies genetic variance.
METHODInter-simple sequence repeat (ISSR) technique was applied for the study.
RESULTFifteen specific and stable primers were selected from 100 primers. A total of 129 sites were generated, and 115 of them (89.15%) were polymorphic. The data analyzed by PopGene demonstrated that the average polymorphic site percentage among the four populations was 71.89%. The average Shannon's information index was 0. 220 4. According to cluster analysis and the law of geographic variation, the populations were classified into two large groups: the Shandong group and the Jiangxi group.
CONCLUSIONThese results will provide the information for protection and utilization of V. trifolia var. simplicifolia and also further data for the study of genetic variation and species differentiation of V. trifolia var. simplicifolia.
