GO — Oryza sativa Indica Group

Summary

BGIOSGA013704 (OiGO, also known as AMP1, COP2, HPT, MFO1) on chromosome 3 of Indica rice encodes a metallocarboxypeptidase with carboxypeptidase activity, belonging to the peptidase M28 family and containing a TFR-like dimerisation domain. The gene is associated with numerous developmental and physiological processes, including photomorphogenesis, flower development, meristem maintenance, leaf vascular tissue pattern formation, root development, embryo development, seed maturation, plant organ senescence, detection of insects, and negative regulation of miRNA-mediated gene silencing. It is linked to traits such as shoot regeneration, leaf formation rate, root architecture, biomass accumulation, dehydration resistance, flowering time, senescence, and seed production. The encoded protein localises to the endomembrane system, endoplasmic reticulum, and plasma membrane. Studies of related genes in other species connect the family to shoot meristem size, cytokinin levels, miRNA translational repression, and abiotic stress responses.
