Molecular Diversity of <i>Cipadessa baccifera</i> (Roth) Miq Based on Inter Simple Sequence Repeats

Abstract

Abstract:Medicinal plants are nature's gifts and used in different traditional medicinal systems of India. Most of the medicinal plants are obtained from forest without proper management and knowledge of collection. For the authentication of medicinal plants from the substituted materials, a genetic diversity study is necessary. In the present investigation molecular diversity of Cipadessa baccifera was carried out using dominant ISSR (inter simple sequence repeats) markers in four different accessions of Western Ghats of South India. Five primers were selected from a total of ten primers based on the reproducibility of the bands. The number of polymorphic loci was 13 and the percentage of polymorphic loci was 56.52. The genetic distance among the populations ranged from 0.0910 to 0.3629 and the genetic identity ranged from 0.6087 to 0.9130. The overall observed and effective number of alleles was about 1.5652 and 1.3913. Nei's overall genetic diversity and Shannon information index were 0.2283 and 0.3349. The dendrogram was constructed based on the UPGMA method and the clusters formed depending upon the genetic characters.
