Resumen

Abiotic stress in the environment is a major concern and a worldwide problem as plants have their own molecular responsive mechanism to deal with the abiotic stress. Thus, we need to explore those compounds which react against abiotic stress or stimulate other compound to compensate abiotic-induced damages. Plant glutathione transferases or glutathione-s transferases (GSTs) are multifunctional enzymes and consist of many classes. GSTs play an important role in alleviating oxidative stress from plants including H2O2 content, reactive oxygen species, and methylglyoxal, etc. In addition, GSTs being hydrophilic, highly reactive, and stable compound effectively scavenges ROS by inhibiting oxidation of thiol (-SH) group and creating redox buffer that aids in the stabilization of cellular redox state while heavy metals detoxify by binding with -SH group and decreased concentration of metals in cytosol. Thus, GST may be used in innovative agricultural and biotechnological tools to develop abiotic resistant transgenic lines. Therefore, the goal of this chapter is to emphasize the importance of GSTs in order to raise awareness about an environmentally safe compound (GST) that can help to alleviate abiotic stress. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.
