psbB — Brassica juncea

Summary

BJUB05G58700S (symbol psbB) on chromosome B05 of Indian mustard (Brassica juncea) encodes a chlorophyll-binding protein that is a core component of Photosystem II, belonging to the PSII_PsbB and PS_antenna-like families. The gene is associated with photosynthetic electron transport in Photosystem II, chlorophyll anabolism, and the general process of photosynthesis. Its product localises to the chloroplast thylakoid membrane and Photosystem II. Associations with flavonoid content and stomatal opening have also been recorded. Related genes in other species link the family to the structural integrity and light-harvesting function of Photosystem II.
