Salt-Induced Effects on Crop Plants and Counteract Mitigating Strategy by Antioxidants System

Abstract

Salinity is one of the important menaces to crop plants. Most of the plants including agricultural crops are glycophytic and are unable to complete their life cycle in high concentration of salt. This chapter summarizes the consequences of salinity on crop plants, oxidative biomarkers, and their effects in plants under salt stress, and discusses the mitigation strategies of the plants to cope with salt stress by both the enzymatic and nonenzymatic defense system. Oxidative stress biomarkers can be classified as the molecules which are adapted in the microenvironment by relationships with reactive oxygen species and antioxidant system molecules which alter in response to the increasing redox stress. Plants adopt mainly two strategies to counteract the effects of high salt concentration, namely enzymatic and nonenzymatic strategies. Soil salinity poses a significant threat to production of agricultural crops worldwide. The advancement in omics is being used in elucidating important plant processes in response to various abiotic stresses. © 2022 John Wiley & Sons Ltd. All rights reserved.
