POL — Brassica oleracea var. botrytis

Summary

BoPOL, encoded by gene BOLND125_C04P001250.1_BOLND125_V1 on cauliflower chromosome 4, is a member of the PP2C family and contains a PPM-type phosphatase-like domain, with protein serine/threonine phosphatase activity and phospholipid binding. This gene is associated with G1 phase, M phase, meristem cell maintenance, regulation of meristem organisation, phyllome development, defense response, and signal transduction. It localizes to the membrane, plasmalemma, and nucleus. Phenotypic associations include root stem cell maintenance, vascular development, embryo development, seedling lethal with meristem termination and reduced floral organs, weak suppression of clv1-1 carpel number phenotype, suppression of shoot meristem defects and carpel number in clv1-1, and short pedicels with erecta phenotype and compact inflorescence. Studies of related genes in other species link the family to stem cell regulation, root and shoot meristem maintenance, and embryo development.
