Molecular Characterization using Directed Amplification of Minisatellite-region DNA (DAMD) Marker in Ficus Sycomorus L. (Moraceae)
Abstract
Background:
Ficus sycomorus L. species exhibited great importance with various applications in pharmacology and medicine studies. However, little attention has been given to its molecular characterization.
Objective:
The study aimed to assess DNA genetic diversity among 16 genotypes of F. sycomorus L. species.
Methods:
Directed Amplification of Minisatellite-region DNA (DAMD) marker has been employed to investigate the genetic relationship among the studied genotypes of F. sycomorus L. species based on the estimated Percent Disagreement Values (PDV).
Results:
Twenty-four DAMD primers produced 194 bands, of which, 145 (74.742%) were polymorphic with Polymorphic Information Content (PIC) average of 0.219. DAMD-PCR application highlighted 12 unique markers characteristic for some studied genotypes. Cluster analysis showed that the studied F. sycomorus L. genotypes were split into two main distinguished clusters, each one was considered as a subspecies. In this respect, F. sycomorus14 and F. sycomorus15 genotypes were considered as subspecies too far from the second one containing the remaining genotypes.
Conclusion:
The DAMD assay successfully highlighted genetic diversity within F. sycomorus species. More accurate molecular markers are required to confirm the current data.
