<em>Oroxylum indicum</em> is an important threatened traditional medicinal plant native to Indian subcontinent. Inter Simple Sequence Repeats (ISSR) markers were used to assess the genetic diversity and population genetic structure of 39 accessions of <em>O. indicum </em> belonging to South and North East India. A total of 92 discernible bands were generated from 17 primers, with 81 (88.04%) being polymorphic, indicating high genetic diversity at the species level. The Nei’s gene diversity (<em>h</em>) was estimated to be 0.2526 within populations, and 0.4027 at the species level. Analysis of molecular variance (AMOVA) showed that the genetic variation was found mainly among populations (68%), but variance within populations was only 32%. In addition, Nei’s differentiation coefficients (<em>G</em><sub>ST</sub>) was found to be high (0.3733), confirming the relatively high level of genetic differentiation among populations. The unweighted pair group method of arithmetic-average (UPGMA) clustering also demonstrated high genetic differentiation between South and North East Indian populations. The estimated gene flow (<em>N</em>m) from <em>G</em><sub>ST</sub> was 0.8393. It indicated that the fragmentation of populations and anthropogenic activities might result in specific evolutionary history. Based on the genetic data, a conservation strategy is proposed for this threatened species. |
