GO — Zea mays

Summary

ZM00001EB060200 (symbol GO, also known as VP8) on maize chromosome 1 encodes a metallocarboxypeptidase (EC 3.4.17.21) with a peptidase M28 domain and a TFR-like dimerisation domain. The gene is associated with the regulation of seed maturation, endosperm and embryo development, meristem maintenance, photomorphogenesis, leaf vascular pattern formation, and anthocyanin and vitamin A/E anabolism. It is linked to traits including plant height, biomass yield, peduncle length, salinity tolerance, and abscisic acid concentration, as well as phenotypes such as shoot regeneration, leaf initiation rate, flowering time, senescence, and root architecture. The encoded protein localises to the endoplasmic reticulum and plasma membrane. Studies of related genes in other species connect the family to shoot meristem size, cytokinin levels, miRNA-mediated translational repression, and dehydration stress resistance.
