POL — Triticum turgidum subsp. durum

Summary

TRITD6BV1G153930, designated POL (TtPOL), encodes a protein serine/threonine phosphatase with EC 3.1.3.16, belonging to the PP2C/PPM-type phosphatase family and exhibiting phospholipid binding and metal binding activities. This gene is associated with meristem cell maintenance, meristem structural organization, phyllome development, polar cell growth, regulation of intracellular signaling and DNA-templated transcription, defense response, and signal transduction. It localizes to the membrane, plasmalemma, nucleus, and mitochondria. Phenotypic associations include seedling lethality, meristem termination with reduced floral organs, and effects on root stem cell maintenance, leaf development, stem cell specification, embryo development, vascular development, and peroxisomal function. Studies of related genes in other species link the family to grain size, plant height, drought tolerance, tassel branch number, leaf angle, root length, and shoot and root meristem development.
