P5CS1 — Phaseolus vulgaris

Summary

PHAVU_008G230300 (PvP5CS1) on chromosome 8 of French bean encodes a protein with glutamate 5-kinase activity, glutamylphosphate reductase activity, and D1-pyrroline-5-carboxylate synthetase activity. The gene is associated with the L-proline biosynthetic process, response to desiccation, hyperosmotic salinity response, response to salt, transition from vegetative to reproductive phase, response to oxidative stress, root development, embryo development ending in seed dormancy, salinity response, response to thirst, and response to abscisic acid. The encoded protein localizes to the cytoplasm, mitochondria, Golgi complex, and plasmodesmata. PvP5CS1 is associated with 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, arsenic tolerance, proline synthesis, root meristem size, fertility, and pollen sterility. Related genes in other species link the family to heat tolerance, drought resistance, root elongation, and abiotic stress tolerance.
