PT — Brassica oleracea var. botrytis

Summary

BoPT, encoded by the gene BOLND125_C08P041250.1 on chromosome 8 of cauliflower (Brassica oleracea var. botrytis), is a metallocarboxypeptidase with carboxypeptidase activity, metal binding and protein binding functions, and belongs to the peptidase M28 family. This gene is associated with a wide range of developmental and physiological processes, including meristem maintenance, flower and root development, leaf vascular tissue pattern formation, seed development, plant organ senescence, and negative regulation of gene silencing by miRNA. It is linked to traits such as callus induction, shoot regeneration, leaf number, flowering time, bolting time, biomass accumulation, seed production, and responses to dehydration and freezing. The encoded protein localises to the endoplasmic reticulum and plasma membrane. Studies of related genes in other species link the family to shoot apical meristem size, photomorphogenesis, cytokinin levels, miRNA-mediated translational repression, and stress tolerance.
