P5CS2 — Brassica oleracea var. botrytis

Summary

BoP5CS2 (BOLND125_C08P042650.1_BOLND125_V1) on cauliflower chromosome 8 encodes a protein with glutamate 5-kinase activity and glutamylphosphate reductase activity, possessing domains characteristic of glutamate-5-kinase and aldehyde dehydrogenase families. This gene is associated with proline transport, L-proline biosynthetic process, hyperosmotic salinity response, microsporogenesis, seed germination, embryo development ending in seed dormancy, response to abscisic acid, and signal transduction. It localises to the cytoplasm, mitochondria, and plasmodesmata. Associations include proline content, pollen fertility, flowering time, embryo lethal proline-rescuable with cotyledon defects, vegetative development, fertility, freezing tolerance, growth and development, salt tolerance, embryo development, pollen development, proline accumulation, salt stress tolerance, sodium ion accumulation, and root meristem size. Related genes in other species link the family to proline biosynthesis, abiotic stress tolerance, root elongation, flowering time, and pathogen resistance.
