VIH1 — Triticum aestivum

Summary

TaVIH1 (TRAESCS4D02G027800) on wheat chromosome 4D encodes a protein with inositol hexakisphosphate 1-kinase, PP-IP5 kinase, and 5-diphosphoinositol pentakisphosphate 1-kinase activities (EC 2.7.4.24), belonging to the VIP1_N and His_PPase_superfam domain families. The gene is associated with inositol phosphate anabolism, inositol metabolism, cellular homeostasis, and lipid metabolism. It is linked to upregulation of antifungal innate immune response, jasmonic acid/ethylene-dependent systemic resistance, defense response to fungi, and upregulation of defense response to insects. Associations also include drought tolerance, salt tolerance (SALTTL), phosphate homeostasis, and stem rust infection response. The encoded protein localises to plastid, cytosol, plasmalemma, and cytoplasm. Related genes in other species link the family to ABA sensitivity, inositol pyrophosphate synthesis, abiotic stress tolerance, and Agrobacterium-mediated plant transformation.
