Aeluropus lagopoides is a halophytic grass growing in different sabkhas of Saudi Arabia. In this study, 14 inter-simple sequence repeat (ISSR) and 15 sequence-related amplified polymorphism (SRAP) molecular markers were selected to investigate the genetic diversity within and among five natural populations of A. Lagopiodes. The genetic diversity varied within and among populations. ISSR markers were slightly more efficient than SRAP markers in evaluating genetic diversity. Average polymorphism information content, effective number of alleles, Nei’s genetic diversity, and Shannon’s information index values of ISSR markers were higher than SRAP. Analysis of molecular variance revealed about 40% genetic variation among the population and 60% within the population. Overall, the genetic diversity was lowest in Jouf (40%), while the Qaseem populations were the highest (60%). Jizan populations were highly dissimilar to other regions. A Mantel test indicated a positive correlation between geographic and genetic distance. The cluster analysis showed three groups; the first group comprises Jouf and Salwa populations, the second group comprises Qareenah and Qaseem, and the third group comprises the Jizan population. This observation matched the geographic distribution of the species. These findings can help in the conservation of a diverse population of A. lagopoides in saline regions as well as rehabilitation of these degraded unique habitats. |
