PT — Glycine max

Summary

GmPT (GLYMA_10G088000V4) encodes a metallocarboxypeptidase with carboxypeptidase activity, metal binding and protein binding functions, and contains peptidase M28 and TFR-like dimer domains. The gene is associated with negative regulation of gene silencing by miRNA, plant organ senescence, meristem cell maintenance, regulation of seed maturation, Pi homeostasis, nitrogen fixation, leaf vascular tissue pattern formation, embryogenesis, and response to salt. It localizes to the endoplasmic reticulum and plasmalemma. GmPT is linked to drought tolerance, leaf water potential, transpiration rate, stomatal resistance, grain weight, and shoot regeneration. Associations also include flowering time, leaf development, senescence, root architecture, cytokinin levels, freezing tolerance, and seed production. Studies of related genes in other species connect the family to shoot meristem size, photomorphogenesis, miRNA translation inhibition, cytokinin levels, and heat tolerance.
