Abstract

Abiotic stress like drought, salinity, heat, and UV radiation results in a reduction of crop growth and yield that threatens the food security at the global level. Different mechanisms has been developed by wheat plant to tackle these abiotic stresses and maintain their growth and yield under harsh conditions. Phytohormones are diverse group of molecules synthesized by plants like abscisic acid (ABA), ethylene (ET), and jasmonate (JA) which are found to be involved in regulation of the protective responses under various abiotic and biotic stress conditions. Exogenous application of phytohormones especially salicylic acid helps wheat crop to cope with abiotic stresses.
