PSP — Cicer arietinum

Summary

LOC101498281 (CaPSP) on chickpea chromosome 5 encodes a protein with L-phosphoserine phosphatase activity and magnesium binding, belonging to the HAD-like serine phosphatase family. The gene is associated with L-serine anabolism, L-serine metabolism, sulfur amino acid metabolism, and localizes to the plastid. CaPSP is associated with pollen development, root development, embryo development ending in seed dormancy, cell cycle, cell death, circadian rhythm, and photorespiration. Associations with chlorophyll content, tapetum development, plant growth, root growth, and male fertility have also been noted. Related genes in other species link the family to embryo development, serine biosynthesis, and cadmium tolerance, as well as associations with nitrogen content, root thickness, and photochemical quenching.
