Summary

Halophytes are plants that survive in environments where the salt concentration is around 200 mM NaCl. The tolerance of halophytes to salinity relies on controlled uptake and compartmentalization of Na+ and the synthesis of compatible solutes. Identification and isolation of novel genes by genomic approaches will advance the understanding of mechanisms of high salt tolerance. Plant stress tolerance can be improved by manipulating stress-associated genes and proteins and/or overexpression of stress-associated metabolites. Here, we discuss the role of possible genes in stress mitigation and tolerance in halophytes and their overexpression to generate stress-tolerant crop plants.
