POL — Brassica juncea

Summary

BJUB06G57280S (symbol POL, preferred name BjPOL) on Indian mustard (Brassica juncea) chromosome B06 encodes a protein with a PP2C/PPM-type phosphatase-like domain and exhibits protein serine/threonine phosphatase activity, phospholipid binding, and metal binding. It localises to the membrane, plasmalemma, and nucleus. This gene is associated with meristem cell maintenance, regulation of meristem organisation, phyllome development, signal transduction, regulation of DNA-templated transcription, and defense response. It has been linked to cytoplasmic male sterility and heterosis, as well as phenotypes including root stem cell maintenance, vascular development, seedling lethality with meristem termination, embryo development, stem cell identity, and short pedicels with a compact inflorescence. Related genes in other species are linked to shoot meristem development, stem cell regulation, and pedicel length.
