TL;DR: The data collectively suggest that the identified SDR protein NYC1 plays essential roles in the regulation of LHCII and thylakoid membrane degradation during senescence.
Journal ArticleDOI
Chlorophyll a oxygenase (CAO) is involved in chlorophyll b formation from chlorophyll a
TL;DR: It is demonstrated that a chlorophyll a oxygenase is involved inchlorophyll b formation and that an overlapping region of a nuclear genome was deleted in all mutants and that this encodes a protein whose sequence is similar to those of methyl monooxygenases.
Journal ArticleDOI
Arabidopsis STAY-GREEN, Mendel's Green Cotyledon Gene, Encodes Magnesium-Dechelatase
TL;DR: It is reported that Mendel’s green cotyledon gene, STAY-GREEN (SGR), encodes Mg-dechelatase, which is not only involved in chlorophyll degradation but also contributes to photosystem degradation.
Journal ArticleDOI
Participation of Chlorophyll b Reductase in the Initial Step of the Degradation of Light-harvesting Chlorophyll a/b-Protein Complexes in Arabidopsis
TL;DR: It is reported that chlorophyll b reductase, which catalyzes the first step of chlorophyLL b degradation, plays a central role in LHCII degradation, and that trimeric L HCII is a substrate of LHC II degradation.
Journal ArticleDOI
The sugar-metabolic enzymes aldolase and triose-phosphate isomerase are targets of glutathionylation in Arabidopsis thaliana: detection using biotinylated glutathione.
TL;DR: This work examined glutathionylated proteins in the suspension-cultured cells of Arabidopsis using biotinylated GSH, which identified two proteins as the key enzymes for sugar metabolism, triose-phosphate isomerase (TPI) and putative plastidic aldolase.
