E112 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0530450 (HvE112) on barley chromosome 5H encodes a protein with cellulose synthase (UDP-forming) activity, also annotated with protein-cysteine S-palmitoyltransferase, cellulase, and SUMO transferase activities, and contains cellulose synthase and zinc finger RING domains. The gene is associated with primary cell wall biogenesis, cellulose microfibril organization, anisotropic cell growth, and regulation of microtubule dynamics. It localizes to the CESA complex, cortical microtubules, and the cell plate. Traits linked to HvE112 include plant vigor, brittle culm, amylopectin content, seed protein content, stem length, biomass yield, root hair length, herbicide sensitivity, and responses to powdery mildew and insect damage. Studies of related genes in other species connect the family to secondary wall thickening, cellulose content, root growth, and seed mucilage development.
