General Information

General Information Comment Organism
physiological function isoform GR2 is an important regulator of leaf senescence. Seed development of the homozygous GR2 knockout mutant is blocked at the globular stage. GR2 RNAi plants display early onset of age-dependent and dark and H2O2-induced leaf senescence, accompanied by the induction of the senescence-related marker genes SAG12 and SAG13. Genes related to leaf senescence, oxidative stress, and phytohormone pathways are upregulated directly before senescence in RNAi plants. H2O2 accumulates to higher levels in RNAi plants than in wild-type plants and the levels of H2O2 peak in RNAi plants directly before the early onset of leaf senescence. RNAi plants show a greater decrease in GSH/GSSG levels than wild-type plants during leaf development Arabidopsis thaliana
physiological function transgenic Arabidopsis plants with decreased chloroplastic/mitochondrial isoform GR2 levels are highly sensitive to excess light and accumulate high levels of H2O2. Photosystem II activity is significantly decreased and plants show inhibition of electron transfer between QA and QB and decreased redox potential of QB. The levels of photosystem II proteins and complexes are decreased in transgenic plants Arabidopsis thaliana
