psbA — Brassica juncea

Summary

BJUUNNG02850S (psbA) in Indian mustard (Brassica juncea) encodes a protein with the PSII_D1 domain, belonging to the D1/D2, Photo_RC_L/M_CS, Photo_RC_L/M, and Photo_II_D1/D2_sf families. 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 photosystem II complex in the chloroplast thylakoid membrane. This gene is associated with photosynthetic electron transport in photosystem II, photoprotection, chlorophyll fluorescence, digestion, and response to herbicide. It has also been connected to chlorophyll content and the SALTTL trait. Related genes in other species link the family to the enzyme class 1.10.3.9.
