03. Molecular basis of salt stress tolerance in crop plants
Main Article Content
Abstract
Plant growth, survival, biomass production and yield are sensitive to abiotic stress factors. Salt stress is major problem for crop plant growth and yield and thus, salinity regard as a main limiting factor in crop productivity. Modern molecular biology tools if we use it explicate salt stress tolerance mechanism and then specific stress related gene expression is used to generate stress tolerant crops. Identification of genes that play important role in salt tolerance in plants when exposed to high salt levels in soil is very important tool to improve plant tolerance in stress condition. In a high salt concentration expression the genes represent salt tolerance mechanism and that information helpful to recover the plant growth under high salt. In high salt concentration, expressions of many genes encoding proteins increase and improve crop plant growth and productivity. In this review, we sum up the work which has been formerly reported about molecular basis of stress tolerance mechanism of crop plants under high salt levels.
