Despite the recent identification of numerous components of the ROS signalling network, understanding how ROS-derived signals are integrated to eventually regulate biological processes as plant growth, development, stress adaption, and programmed cell death remains a challenge. The outcome or fine-tuning of biological responses to changed ROS levels is determined by interactions with other signalling molecules. At every stage of plant growth, the network of redox signals orchestrates metabolism to regulate energy production and use, interfering with major signalling agents (hormones) to respond to changing environmental stimuli. By altering the cell’s redox balance, ROS may serve as a “second messenger”, influencing the activities of specific proteins or gene expression. One of the particular early stress responses in the plant’s acclamatory performance is the molecular language linked with ROS-mediated signal transduction, which leads to gene expression modulation. ROS level changes in space and time are viewed as signals for a variety of biological activities, including growth, development, tolerance to abiotic stress factors, and correct response to stress. They destroy biomolecules and trigger genetically programmed cell suicide events at high concentrations, but operate as a second messenger in intracellular signalling cascades that mediate a variety of responses in plant cells at low concentrations. Depending on their abundance in plants, ROS can play both detrimental and helpful effects. The orchestration of the plant response to abiotic stress and the driving of changes in transcriptomic, metabolic, and proteomic networks that lead to plant acclimation and survival is mediated by the integration of these signalling events, which is mediated by an interplay between ROS and different plant hormones. Early and late signal transduction events involving essential signalling molecules such as reactive oxygen species (ROS), various plant hormones, and other signalling molecules are required for this response. Improving crop tolerance to abiotic stress conditions necessitates a thorough understanding of plant responses to environmental changes. ![]() Because of the growing rate and intensity of global climate changes, the effects of these adverse conditions on plant productivity have become increasingly worrying in recent years. Each year, abiotic stress factors such as drought, heat, salinity, and cold, as well as their many combinations, take a toll on agricultural productivity all over the world. ![]()
