Cereals and Phytohormones Under Salt Stress

Abstract

Cereal crops are occupying a dynamic part in nourishing the whole population of the world. The development and production of these cereal crops are poorly affected when exposed to different environmental abiotic stresses, among which salinity stress plays a major role. Plants that respond to salt stress involve various complex physiological, molecular, as well as biochemical changes in the plant system. Phytohormones play a crucial role in acquiring some adaptational reactions in a plant's system when exposed to salinity. Gibberellins (GAs), ethylene (ET), cytokinins (CKs), salicylic acid (SA), jasmonates, abscisic acid (ABA), and brassinosteroids (BRs) are important plant hormones that respond to salinity stresses via their signalling attributes. The cellular disturbances caused by salinity stress are potentially removed by exogenous phytohormones in plants. Phytohormones extensively regulate some specific genes to deal with saline conditions. In this chapter, the collective information is mentioned which is focused on the role of phytohormones along with the involved genes in the alleviation of salinity stress in cereal crops. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022
