POL — Brachypodium distachyon

Summary

BdPOL (BRADI_2G31973V3) on chromosome 2 of Brachypodium distachyon encodes an uncharacterized protein with annotated serine/threonine phosphatase activity and phospholipid binding, and is associated with meristem cell maintenance, regulation of meristem organisation, phyllome development, polar cell growth, defense response, and signal transduction. It localises to the nucleus, plasmalemma, and mitochondria. Phenotypic associations include seedling lethality, meristem termination with reduced floral organs, root stem cell maintenance, leaf development, stem cell identity, stem cell specification, embryo development, weak suppression of clv1-1 carpel number phenotype, suppression of shoot meristem defects and carpel number in clv1-1, short pedicels with erecta phenotype and compact inflorescence, stem cell maintenance, peroxisomal function, and vascular development. Studies of related genes in other species link the PP2C family to traits such as grain size, plant height, drought tolerance, tassel branch number, leaf angle, root length, and seed germination, as well as phenotypes including pedicel length, meristem development, and embryo patterning defects.
