KEY MESSAGE : The role of transporters in imparting salt tolerance to mangroves is not yet understood. Identification of the role of transporters in halophytes is promising, as far as the development of genetically engineered salt tolerant crops is concerned. Mangroves are models for stress tolerance and they provide a reservoir for some of the novel genes and proteins, involved in salt tolerance. Biochemical or physiological mechanisms contribute to salt tolerance depending on variations in the environment. A great deal of research on salinity tolerance of plants, probes into water relations, photosynthesis, and accumulation of various in-organic ions and organic metabolites. The ability of the plant to react to high salinity depends on the genes that are expressed during stress. The mechanism of salinity tolerance becomes complicated when the responses of plants varies with salinity and environmental conditions. During the onset and development of salt stress within a plant, major processes such as photosynthesis, protein synthesis and lipid metabolisms are affected. The present review attempts to dissect out the role of transporters in salt tolerance of mangroves.
