P5CS — Phaseolus vulgaris

Summary

PHAVU_010G015400, symbol P5CS (PvP5CS) on French bean chromosome 10, encodes a protein with glutamate 5-kinase activity and glutamylphosphate reductase activity, and is associated with the L-proline biosynthetic process. The protein contains multiple conserved domains including Glu_5kinase/ProBA and aldehyde dehydrogenase domains, and localises to the cytoplasm. This gene is associated with response to salt and salinity stress, cell wall assembly, and proline content. It is also linked to drought tolerance, photosynthetic rate, and the SALTTL trait. Studies of related genes in other species connect the P5CS family to additional traits such as plant height, root length and volume, leaf chlorophyll content, net photosynthetic rate, transpiration rate, stomatal resistance, and abscisic acid sensitivity.
