PSBA — Brassica juncea

Summary

BJUA01G04520S (symbol PSBA, also known as BjPSBA) encodes a protein with the PSII_D1 domain, a core component of photosystem II. The product possesses oxidoreductase activity acting on diphenols with oxygen as acceptor, oxygen-evolving activity, chlorophyll binding, electron transfer activity, and iron binding. It is localised to the chloroplast thylakoid membrane as part of photosystem II. The gene is associated with photosynthetic electron transport in photosystem II, photoprotection, chlorophyll fluorescence, chlorophyll anabolism, digestion, and response to herbicide. It has been linked to traits including chlorophyll content, flavonoid content, stomatal opening, and salt tolerance. Studies of related genes in other species connect the PSBA family to leaf temperature regulation.
