ALX8 — Triticum aestivum

Summary

TRAESCS5B02G121500 (symbol ALX8, also known as Sal1) on wheat chromosome 5B encodes a protein with inositol bisphosphate phosphatase activity (EC 3.1.3.7), inositol-1,4-bisphosphate 1-phosphatase activity, and 3'(2'),5'-bisphosphate nucleotidase activity, belonging to the inositol monophosphatase-like family. The gene is associated with inositol phosphate metabolism, phosphoinositide-mediated signaling, auxin export, miRNA catabolism, sulfate assimilation, detection of oxidative stress, pre-harvest sprouting, regulation of jasmonic acid biosynthesis, and membrane fission. It is linked to drought tolerance, salt stress tolerance, freezing tolerance, aluminum resistance, seed germination, stomatal closure, leaf senescence, biomass yield, root growth, and phototropism. The encoded protein localizes to the plasma membrane, vesicle membrane, and ER body. Related genes in other species are linked to polar auxin transport, gravitropism, and stress-responsive gene expression.
