POL — Brachypodium distachyon

Summary

BdPOL (BRADI_1G03690V3) on Brachypodium distachyon chromosome 1 encodes a protein with a PP2C domain and PPM-type phosphatase-like domain, possessing protein serine/threonine phosphatase activity, phospholipid binding, and metal binding. This gene is associated with meristem cell maintenance, meristem structural organization, phyllome development, polar cell growth, regulation of intracellular signaling, defense response, signal transduction, and regulation of DNA-templated transcription. It localizes to the nucleus, membrane, plasmalemma, and mitochondria. Phenotypic associations include seedling lethality, meristem termination with reduced floral organs, root stem cell maintenance, leaf development, stem cell specification, embryo development, suppression of shoot meristem defects, short pedicels with compact inflorescence, and vascular development. Studies of related genes in other species link the family to traits including plant height, grain size, drought tolerance, tassel branch number, leaf angle, root length, and seed germination.
