文摘The elaborate redox network of the cell,comprising of events like turnover of reactive oxygen species(ROS),redox sensing,signaling,expression of redox-sensitive genes,etc.,often orchestrates with other bonafide hormonal signaling pathways through their synergistic or antagonistic action in the plant cell.The redox cue generated in plant cells under fluctuating environmental conditions can significantly influence other hormonal biosynthetic or signaling mechanisms,thereby modulating physiology towards stress acclimation and defense.There is also strong evidence of the recruitment of ROS as a‘second messenger’in different hormonal signaling pathways under stress.Moreover,the retrograde signaling initiated by ROS also found to strongly influence hormonal homeostasis and signaling.The present review,in this aspect,is an effort towards understanding the regulatory roles of ROS in integrating and orchestrating other hormonal signaling pathways or vice versa so as to unfold the relationship between these two signaling episodes of plant cells under environmental odds.We also accentuate the significance of understanding the utterly complex interactions,which occur both at metabolic and genetic levels between ROS and phytohormones during stress combinations.Furthermore,the significant and decisive role of ROS turnover,particularly the contribution of RBOH(respiratory burst oxidase homologs)in the synergism of redox and hormone signaling during systemic acquired acclimation under stress is also discussed.
