Abstract: The cosmopolitan species Avicennia marina (Forsk.) Vierh (Acanthaceae) lives in mangrove forests, which are the most productive and chemically active ecosystems. Mangroves in coastal areas around the world have gotten worse because of human interference, control, and activities in them, such as reclaiming land, growing populations, overgrazing, polluted factory spills, and dumping waste. This has emerged very significantly after the Gulf War, and its damage will remain for a long time until we can grow it again and protect the rest of it. All of the above led to this study, which shows how genetically different A. marina is in different places. The study included testing the genetic accessions of A. marina samples under study collected from different sites along the Arabian Gulf of the Saudi Arabia Kingdom. This was done using the Inter Simple Sequence Repeat (ISSR).11 out of 16 primers were able to bind to cut the DNA of the species and give clear and stable bands, the rest did not give any clear bands so they were excluded. The total number of similar bundles was 1165, and the total number of dissimilar bundles was 1118; hence, the polymorphism rate of the studied species was calculated as 96.0%. This percentage of genetic variability is significant for progress in growth and plant regeneration in the face of unfair practices against it, in addition to adverse environmental conditions in most years. This result concerns knowing the genetic diversity of the plant community is an essential step towards the design of programs for plant breeding as well as preserving it from extinction.
