POL — Triticum turgidum subsp. durum

Summary

TRITD1AV1G006720 (POL, also known as TtPOL) on durum wheat chromosome 1A encodes a protein serine/threonine phosphatase with EC 3.1.3.16, possessing 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, defense response, and signal transduction. It localizes to the nucleus, membrane, plasmalemma, and mitochondria. Phenotypic associations include seedling lethality, meristem termination with reduced floral organs, stem cell maintenance and specification, leaf and vascular development, embryo development, and suppression of shoot meristem defects. Studies of related genes in other species link the POL family to traits including grain size, plant height, drought tolerance, tassel branch number, leaf angle, root length, and seed germination.
