CIARC_P001 — Cicer arietinum

Summary

CIARC_P001 (PSBA, psbA) encodes the D1 protein of photosystem II, a core component of the photosynthetic reaction centre. 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 within photosystem II. In chickpea, PSBA is associated with photosynthetic electron transport in photosystem II, response to herbicide, and RNA metabolism. Studies of related genes in other species connect the PSBA family to protein content, though this association is not yet established in chickpea.
