Overview of major genes that involved in abiotic stress resistance through ROS regulation in crop plants. Plant cells perceive abiotic stress signals and transduce them through various signaling pathways including secondary signaling molecules, plant hormones, and transcriptional regulators. The regulation of gene expression by different transcription regulators results in the induction of various defense pathways, such as, reactive oxygen species (ROS) scavenging and antioxidative metabolism. Transcription regulators also mediate ROS producing systems and activate the expression of stress-responsive gene so as to confer tolerance to the environmental stresses. CDPK, calcium-dependent protein kinase; CIPK, calcineurin B-like protein-interacting protein kinase; MAPK, mitogen-activated protein kinase; PK, protein kinase; PP, protein phosphatase; SRO, similar to RCD one.
