P5CS1 — Phaseolus vulgaris

Summary

PHAVU_001G236900, designated PvP5CS1 on chromosome 1 of French bean (Phaseolus vulgaris), encodes a protein with glutamate 5-kinase activity, glutamylphosphate reductase activity, and D1-pyrroline-5-carboxylate synthetase activity. This gene is associated with L-proline biosynthesis, response to desiccation, hyperosmotic salinity response, response to salt, response to oxidative stress, response to abscisic acid, root development, embryo development ending in seed dormancy, and transition from vegetative to reproductive phase. The encoded protein localises to the cytoplasm, mitochondria, plasmodesma, and Golgi complex. PvP5CS1 is linked to proline content, photosynthetic rate, salt tolerance, proline accumulation, drought tolerance, stress tolerance, pollen development, pollen fertility, embryo development, salt stress tolerance, reactive oxygen species accumulation, water stress tolerance, root elongation at low water potential, NADP/NADPH ratio, inflorescence architecture, plant height, flowering time, freezing tolerance, salt response, drought response, reduced proline accumulation under salt stress, proline deficiency with oxidative stress under salt, proline deficiency with salt stress hypersensitivity, reduced proline accumulation with salt hypersensitivity and increased oxidative stress, salt stress response, arsenic tolerance, proline synthesis, root meristem size, fertility, and pollen sterility. Related genes in other species link the family to osmotic stress
