Study of Genetic Diversity of Hara Trees on the Coast of Hormozgan Province Using Rapid Molecular Method

Abstract

In order to study the genetic diversity of Hara trees in the coastal waters of Hormozgan province, using 40 RAPD molecular samples, 40 samples of Hara leaves were collected at different stations (ports of Jask, Dumitry, Tiba and Qeshm Island) and transferred to the laboratory. After extraction of DNA They were examined by 30 primers in polymerase chain reaction. The results showed that the highest mean genetic variation in Qeshm population was 0 458 with a standard deviation of 0.033 and the lowest mean of genetic diversity in Jask population was 0.423 with a standard deviation of 0.056. Also, using the PopGene software, the average Shannon information index was 0.643 for four populations. The value of Fst index was 011/0 and the gene flow rate was 25.854, and the UPGMA dendrogram, based on the Nei genetic distance, did not show a clear separation between the populations. Also, molecular variance analysis showed that there is a high variation (99%) within the studied populations. The results of this research can provide useful information for conservation and management programs of this kind with indigenous value of Iran.
