Therefore, redox and ros information from the photosynthesizing chloroplasts is transmitted to the cytosol and controls rapid adjustments to transcription and translation. Under such conditions, reactive oxygen species (ros) are generated via transfer of excess electrons to oxygen Similar events can occur under the changing light environment, which directly affects the photosynthetic light reactions. In plants, the production of reactive oxygen species (ros) is a predictable outcome of an aerobic lifestyle The evolution of photosynthesis and its associated metabolic pathways has been crucial to the successful establishment of plants, but has also challenged plant cells in the form of production of reactive oxygen species (ros). During the metabolic processes of plant cells, ros can be generated via multiple pathways.
Oxygenic photosynthesis provides oxygen and food for most life forms through the use of sunlight, co2, and water Reactive oxygen species (ros) are formed in photosystem ii (psii) under various types of abiotic and biotic stresses Chloroplasts are considered as one of the most important producers of ros in plant cells and, more specifically, the light reactions of photosynthesis Under most abiotic stresses, the absorbed light energy exceeds the energy that it can handle, and thus it can damage the photosynthetic apparatus. The main source of ros generation in plant cells under normal light conditions is the chloroplast, but other organelles such as mitochondria and peroxisomes also contribute to ros formation.
