PT — Glycine max

Summary

GmPT (GLYMA_19G203400V4) encodes a metallocarboxypeptidase with peptidase M28 and TFR-like dimer domains, and is associated with carboxypeptidase activity and metal binding. In soybean, this gene is linked to the regulation of seed maturation, meristem cell maintenance, plant organ senescence, nitrogen fixation, phosphate homeostasis, and response to salt stress. It localizes to the endoplasmic reticulum and plasma membrane. GmPT is associated with drought tolerance, leaf water potential, transpiration rate, and stomatal resistance, as well as grain weight and harvest index. Phenotypic associations include shoot regeneration, biomass accumulation, flowering time, leaf development, root architecture, and senescence. Studies of related genes in other species link the family to shoot meristem size, photomorphogenesis, cytokinin levels, miRNA-mediated translational repression, and heat tolerance.
