Gene : NYE1 A. thaliana

DB identifier  ? AT4G22920 Secondary Identifier  ? locus:2127153
Name  ? NON-YELLOWING 1 Brief Description  non-yellowing 1
TAIR Computational Description  non-yellowing 1;(source:Araport11)
TAIR Curator Summary  Similar to the tomato senescence-inducible chloroplast stay-green protein 1. It is upregulated during maximal senescence in the Arabidopsis life cycle, especially in senescent leaves. Acts antagonistically with SGR2 to balance chlorophyll catabolism in chloroplasts with the dismantling and remobilizing of other cellular components in senescing leaf cells.
TAIR Short Description  non-yellowing 1
TAIR Aliases  ATNYE1, NYE1, SGR, SGR1

SGR1_ARATH developmental stage Constitutively expressed at low level during leaf development, but up-regulated during seed maturation and senescence, when the leaf color changes from green to yellow.
SGR1_ARATH function Magnesium chelatase involved in chlorophyll a degradation in the chlorophyll-protein complexes of photosystem I (PSI) and photosystem II (PSII) (PubMed:27604697). Contributes to the degradation of PSI and PSII in the thylakoid membranes (PubMed:27604697). Required to trigger chlorophyll degradation during natural and dark-induced leaf senescence (Probable) (PubMed:17468209). Mediates chlorophyll degradation during embryo degreening (PubMed:24043799, PubMed:28873256). Recombinant SGR1 possesses high dechelating activity against chlorophyll a, very low activity against chlorophyllide a, and no activity against chlorophyll b (PubMed:27604697). Magnesium dechelation of chlorophyll a by SGR1 activates chlorophyll b degradation by inducing the expression of NYC1, an enzyme involved in chlorophyll b degradation (PubMed:29425814).
SGR1_ARATH similarity Belongs to the staygreen family.
SGR1_ARATH tissue specificity Expressed in roots, leaves, seeds, flowers, buds, petals, sepals and siliques.
