POL — Triticum turgidum subsp. durum

Summary

TRITD1BV1G008190 (POL, also known as TtPOL) encodes a protein serine/threonine phosphatase with EC 3.1.3.16, belonging to the PP2C and PPM-type phosphatase families, and exhibits phospholipid binding and metal binding activities. The gene is associated with meristem cell maintenance, meristem structural organization, phyllome development, polar cell growth, regulation of intracellular signaling, and defense response. It localizes to the nucleus, membrane, plasmalemma, and mitochondria. Phenotypic associations include seedling lethality, meristem termination with reduced floral organs, and effects on stem cell maintenance, leaf development, embryo development, and vascular development. Studies of related genes in other species link the family to grain size, plant height, drought tolerance, root length, tassel branch number, and shoot and root meristem development, though these are not established for durum wheat.
