Photosynthetic Antenna Size Regulation as an Essential Mechanism of Higher Plants Acclimation to Biotic and Abiotic Factors: The Role of the Chloroplast Plastoquinone Pool and Hydrogen Peroxide
Abstract:The present chapter describes the mechanisms of reactive oxygen species formation in photosynthetic reactions and the functional significance of reactive oxygen species as signal messengers in photosynthetic cells of plants. Attention is given to the acclimation mechanisms of higher plants to abiotic and biotic factors such as increased light, drought, soil salinity and colonization of plants by rhizosphere microorganisms. Special attention is paid to the reactions of reactive oxygen species with the component… Show more
“…The antenna size of the supercomplex is adjusted in response to long-term high-light intensity (Wu et al 2020). Plants' acclimation to changing light conditions may be regulated even by the expression of lhcb genes (Borisova-Mubarakshina et al 2022). Effective plant acclimation to prolonged periods of high light is crucial for plants' survival and competitiveness.…”
