MSP — Cucumis sativus

Summary

CsMSP (CSA_6G488340) on cucumber chromosome 6 encodes the oxygen-evolving complex 33 kDa subunit (OEC33), a component of the photosystem II (PSII) oxygen-evolving complex. The gene product exhibits oxygen-evolving activity, NAD(P)H dehydrogenase (quinone) activity, and protein phosphatase regulator activity, and localizes to the chloroplast thylakoid lumen and PSII complex. CsMSP is associated with photosystem II stabilization and assembly, light reactions of photosynthesis, pigment anabolism, and chloroplast disassembly. It is linked to leaf width and length, plant height, chlorophyll content, net photosynthetic rate, photosynthetic ability, and photosynthetic rate. The gene is also associated with drought tolerance, salt tolerance, osmotic response sensitivity, zinc sensitivity, herbicide sensitivity, disease tolerance, oxidative stress response, leaf senescence, root meristem development, adventitious root development, meristem growth and identity, and male and female gamete generation.
