LEA22 — Triticum aestivum

Summary

TRAESCS3A02G254600, designated TaLEA22 (also known as LEA22-3A or RAB25), encodes a protein with a dehydrin domain on wheat chromosome 3A. The product exhibits lipid, phosphoinositide, phosphatidylglycerol, phosphatidylserine, phosphatidate and metal binding activities. TaLEA22 is associated with responses to water, freezing, mannitol and salinity, as well as abscisic acid metabolism, stomatal opening, proline metabolism, hormone metabolism, cellular salinity response, wax anabolism, sucrose metabolism, gluconeogenesis, the TCA cycle, glycan biosynthesis, ATP anabolism, interphase, digestion and clotting. The protein localises to the vesicle membrane, cytosol, cytoplasm and nucleus. TaLEA22 is associated with winter survival, sprouting tolerance, osmotic adjustment capacity, drought sensitivity, biological yield, stand establishment, test weight, plant vigor, relative growth rate, leaf water potential, leaf relative water content, grain iron and zinc content, starch, fructose, sucrose and carbohydrate concentrations, seed dormancy and germination, abscisic acid content and response, and seed, pericarp, coleoptile and leaf colour.
