PHS1 (TRAESCS1D02G265200) — triticum aestivum

Summary

TRAESCS1D02G265200 (TaPHS1) on wheat chromosome 1D encodes a dual specificity protein phosphatase PHS1 with actin-fragmin kinase catalytic and tyrosine phosphatase domains. It exhibits JUN kinase phosphatase, myosin phosphatase, and protein tyrosine phosphatase activities, and is annotated as a structural constituent of the cytoskeleton. TaPHS1 is associated with pre-harvest sprouting and seed dormancy in wheat. It is linked to sprouting tolerance, vivipary, grain color, grain weight, grain number, grain protein content, harvest index, ear number, tiller number, flag leaf senescence, grain filling period, anthesis time, root length and thickness, shoot growth angle, leaf size, chlorophyll content, stomatal opening and closure, auxin sensitivity, water-use efficiency, biotic stress resistance, and disease tolerance. The gene product localizes to the microtubule cytoskeleton, cytoplasm, nucleus, endoplasmic reticulum, mitochondria, and plasmalemma, and is associated with microtubule-based processes, seed germination, meiosis, DNA recombination, and responses to auxin, fungi, and carbon dioxide.
