Abstract
In order to meet the food requirements of our growing population, the agricultural
land has been expanded worldwide but still certain constraints (stress factorsabiotic and biotic) exist that limit the yield of many crops. These constraints/stress
factors cause severe damage to the crop. These abiotic stresses including drought,
salinity, cold and extreme temperature, etc. led to a drastic reduction in the yield
of the number of crops and among all of these, salinity is becoming more severe
problem day by day. Salinity hampers the growth and development of plants by
inducing several changes like osmotic stress, ion toxicity, oxidative stress (ROS),
membrane disorganisation, etc. and thus poses a major threat to agricultural yield.
Several approaches have been applied to develop salt-tolerant plants to reduce the
destruction of crops caused by salinity. In this regard, conventional breeding
proved very tedious while in vitro techniques proved useful as they provide keen
