OE33 — Pisum sativum
Summary
PSAT4G089880 (OE33, PSBO) on garden pea chromosome 4LG4 encodes the PsbO family protein, a 33 kDa subunit of the oxygen-evolving complex (OEC) with oxygen-evolving activity, NAD(P)H dehydrogenase (quinone) activity, and protein phosphatase regulator activity. The gene is associated with photosystem II stabilization, assembly, and repair, nonphotochemical quenching, thylakoid membrane organization, chloroplast disassembly, de-etiolation, meristem growth, and gamete generation. It localizes to the chloroplast photosystem II, thylakoid lumen, and OEC complex. The gene is linked to photosynthetic rate, photochemical quenching, drought tolerance, salt tolerance, oxidative stress tolerance, cold stress tolerance, herbicide sensitivity, zinc sensitivity, leaf senescence, disease tolerance, and root and inflorescence morphology traits. Studies of related genes in other species connect the family to photoinhibition resistance, osmotic stress tolerance, and reactive oxygen species homeostasis.
