DVR — Brassica oleracea

Summary

BoDVR (BOLC102_C09P061320.1_BOLC102_V1) on cabbage chromosome 9 encodes a DVR-like protein with NAD(P)-binding domains and 3,8-divinyl protochlorophyllide a 8-vinyl reductase activity. The gene is associated with chlorophyll metabolism, including both biosynthesis and breakdown, as well as anthocyanin biosynthesis. It has been linked to chloroplast development, thylakoid grana stacking, chlorophyll b accumulation, and petal greening. Localisation evidence connects the product to chloroplast thylakoids, envelope, plastids, and mitochondria. Associations with leaf color and respiration rate have also been recorded. Studies of related genes in other species link the DVR family to chlorophyll b content, petal color, chloroplast development traits, and photochemical quenching, with phenotypes including pale-green leaves, reduced growth, and disorganized thylakoids.
