DVR — Cucumis sativus

Summary

CSA_3G151460 (DVR, also known as CsBPG1, CsDVR, PCB2, BPG1, or CsPCB2) in cucumber (Cucumis sativus) on chromosome 3 encodes a protein with 3,8-divinyl protochlorophyllide a 8-vinyl reductase activity (EC 1.3.1.75), placing it in the DVR-like family with a NAD(P)-binding domain. The gene is associated with chlorophyll metabolism, including chlorophyll anabolism and photoprotection, as well as carotenoid anabolism, photorespiration, secondary metabolism, and homeostasis. It has been linked to leaf color, leaf chlorosis, chlorophyll content, and salt tolerance (SALTTL). The encoded protein localizes to the chloroplast thylakoid, chloroplast envelope, plastid, and mitochondria. Related genes in other species are associated with chlorophyll biosynthesis, greening, and chloroplast development traits such as thylakoid organization and starch granule formation.
