NYC1 — Cucumis sativus
Summary
CsNYC1 (CSA_1G250130) on cucumber chromosome 1 encodes a protein with chlorophyll b reductase activity (EC 1.1.1.294) and additional annotated activities including 7-hydroxymethyl chlorophyll a reductase, pheophytinase, and RCC reductase activities, belonging to the Chl_b_Red and short-chain dehydrogenase/reductase families. The gene is associated with chlorophyll breakdown and the chlorophyll cycle, as well as cell dedifferentiation, sex determination, meristem development, flower development, and regulation of programmed cell death and the hypersensitive response. It is linked to leaf yellowing tolerance, chlorophyll content, stem senescence, yield traits, seed maturation, disease tolerance, and root morphology. The product localizes to the thylakoid, chloroplast thylakoid membrane, envelope, and stroma. Related genes in other species are linked to leaf cell death, chlorophyll catabolism, stay-green phenotypes, and disease symptom development.
