POL — Brassica napus

Summary

BnPOL (POL, DARMORV10_A05P00910.1) on chromosome A05 of oilseed rape encodes a protein with a PP2C domain and PPM-type phosphatase-like domain, annotated with protein serine/threonine phosphatase activity and phospholipid binding. The gene is associated with meristem cell maintenance, regulation of meristem organisation, anther and phyllome development, sexual reproduction, and programmed cell death. It is linked to defense response, signal transduction, DNA repair, homologous recombination, RNA processing, and homeostasis. Localisation evidence connects the product to the membrane, plasmalemma, and nucleus. The gene has been associated with cytoplasmic male sterility and phenotypes including root stem cell maintenance, vascular development, embryo development, and meristem termination with reduced floral organs. Related genes in other species link the family to shoot and root meristem development, stem cell regulation, and pedicel length.
