P5CS — Cicer arietinum

Summary

GmP5CS on chickpea chromosome 3 encodes a protein with glutamate 5-kinase activity and glutamylphosphate reductase activity, and is associated with L-proline biosynthetic process, proline metabolism, proline breakdown, regulation of proline anabolism, arginine metabolism, glutamate metabolism, polyamine anabolism, chlorophyll a anabolism, H2O2 biosynthetic process, and homeostasis. The gene is linked to proline content, photosynthetic rate, stomatal resistance, transpiration rate, leaf chlorophyll content, cell membrane stability, plant height, and drought tolerance. The encoded protein localises to both cytoplasm and nucleus and is also associated with DNA binding, transcription cis-regulatory region binding, nucleus fragmentation, embryogenesis, biofilm formation, chemotaxis, and nitrogen fixation. Studies of related genes in other species connect the family to net photosynthetic rate, root volume, leaf area index, grain weight, acid sensitivity, leaf chlorosis, salt tolerance, root length, and abscisic acid sensitivity.
