DPE1 (TRAESCS2D02G166600) — triticum aestivum

Summary

TRAESCS2D02G166600, designated TaDPE1 on bread wheat chromosome 2D, encodes a 4-alpha-glucanotransferase belonging to the glycoside hydrolase family 77. The enzyme possesses heteroglycan and starch binding activities and is localized to the amyloplast and cytosol. TaDPE1 is associated with starch metabolism, starch breakdown, maltose breakdown, glucose metabolism, and polysaccharide breakdown. It is also linked to grain iron and zinc content, grain protein content, grain yield per plant, seed weight, grain length, test weight, harvest index, heading time, stand establishment, plant vigor, drought sensitivity, starch mobilization, sugar content, and coleoptile, pericarp, seed coat, leaf, and grain color. The gene is also associated with DNA metabolism, epigenetic regulation of gene expression, cell organization, cell cycle, and male sterility. Related genes in other species link the family to starch degradation and embryo development.
