UNRAVELING THE ROLE OF ROS IN PLANT DEFENSE AND STRESS ADAPTATION MECHANISMS
Mohamed M. Zayed
Abstract
Reactive oxygen species (ROS) play significant roles in plant growth, development, and in mediating responses to environmental cues. ROS, also known as oxygen radicals and their derivatives, are produced by plant cells during a variety of biotic stress-related events. Plant tolerances under abiotic stress conditions are achieved by increasing the production of compatible osmolytes, compatible solutes, ROS and regulation of ion homeostasis. Nowadays these non-specific stress reactions were mostly described in the scientific literature. Plant metabolites under environmental stress is special topic due high biodiversity of metabolites in plants which occur specific plant defence reaction depending from plant origin. Each plant species may exhibit unique biochemical and physiological responses depending on its origin and ecological niche. For example, adaptations such as specialized root structures, leaf waking or size, night blooming, reproducing without seeds, brightly colored flowers, and poisonous plant parts illustrate how plants adjust to diverse environmental conditions. However, the knowledge about the crop responses under abiotic stress environments is still not properly explicit. Eventually, the development of tolerant cultivars has become a challenge now. Therefore, it is essential to explore novel strategies and integrate modern technologies to better define current limitations and accelerate the development of resilient crop varieties. In this context, our study focuses on emerging technological advancements that hold promise for enhancing crop performance and promoting sustainable agricultural practices under stress-prone environments.
