The Mangroves are highly threatened by certain ecologically condition and there arise a need of critical management and protection of those species because of  vital role in protecting the coastal areas of their ecosystem. The diversity of these plants with respect to genetics is well understood but the genetic variations of those species in gulf countries were scattered on the basis of reports from literature. The main aim of the current review is to collect all the available literature for creating a comprehensive viewpoint of different works on the basis of genetic variations in Mangroves. With so little known, it will be important to monitor the responses of mangroves to global warming to minimize the impacts and reestablishing mangroves.
