angroves, the distinctive plant populations of tropical and sub-tropical coastlines, have attracted considerable scientific
attention during the last few decades. High salinity, periodical tidal influence, strong winds, high temperatures, high
precipitation and extremely anaerobic soils are the typical physiognomies of this vegetation.They possess unique morphological
and physiological adaptive features to cope with these extreme conditions. Mangrove forest provides support significantly to
the coastal inhabitants both productive and protective ways. Since industrial revolution, due to elevated salinity, caused by
several environmental and anthropogenic liabilities, it suffers much throughout the world. As the mangroves are assemblage
of heterogeneous group of taxa, they exhibit differential magnitude of adaptability in relation to sustainability. Apart from the
different morphological and physiological adaptive traits, wide genetic plasticity complies as a vital role towards sustainability.
Present work describes the molecular (enzymes and genetic polymorphism) validation of four mangroves (Bruguiera
gymnorrhiza, Excoecaria agallocha, Heritiera fomes and Xylocarpus grnatum) from Indian Sundarbans, of which first two
are well-growing and rest suffer much from enhanced substrate salinity since last three decades. Peroxidase and Superoxide
Dismutase (in different isoforms) are antioxidant enzymes subsidizing the combating forces against ROS-damaged crisis of
pant cell in traumatic substrate. In the present work, it was revealed that, both the enzymes show excess isoforms in Bruguiera
and Excoecaria than the other two. It also presumed that genetic diversity is allied to morphological variance and survival
of the plants. DNA polymorphic experiments with molecular markers (RAPD and ISSR) also revealed that percent DNA
polymorphism are higher in the first two taxa over Heritiera and Xylocarpus. Enzyme and marker assisted molecular study
might be pointed out towards the differential sustainability among the studied taxa in the presently elevated saline regime of
Sundarbans mangrove swamps.
