Genetic diversity of Cordia myxa L. assessed by ISSR markers

Abstract

A large number of species of Cordia (Boraginaceae) are found across the tropical and subtropical parts of the planet. Cordia species are mentioned in popular medicine as being used to cure a variety of ailments affecting a variety of human organs. Population genetic structure, genetic diversity, and phenotypic variation are unknown for this species in Iran. For this reason, we collected morphological as well as molecular data on this plant species, which is significant in its own right. We employed 70 plants that were randomly picked from seven geographical communities spread throughout four provinces to conduct our research. These populations' genetic diversity variables were analyzed. The results of the structure and K-Means grouping analyses indicated the existence of five distinct gene pools in the nation, which were isolated from one another geographically. Genetic and geographical separation were shown to be correlated using the Mantel analysis. Among communities, AMOVA found considerable genetic differences, with within-population variance accounting for around 55% of the overall genetic variability. Upcoming breeding and conservation efforts for this vital medicinal plant in the nation may benefit from these findings.
