GCN5 — Triticum aestivum

Summary

TaGCN5 (TRAESCSU02G003200) on bread wheat chromosome NW_025225271.1 encodes a protein with a bromodomain and a GNAT acetyltransferase domain, and exhibits histone acetylase activity toward H3 and H4, as well as NADH diphosphatase, xyloglucan 6-xylosyltransferase, and clathrin light chain binding activities. The gene is associated with co-transcriptional chromatin reassembly, cuticle pattern formation, regulation of cutin and wax anabolism, xyloglucan and mucilage biosynthesis during seed coat development, starch biosynthesis regulation, miRNA processing, and vegetative phase change. It is linked to traits including starch grain size and content, biomass yield, ear number, photosynthetic ability, wheat stripe rust disease response, temperature stress responses, root hair length, lateral root length, anthocyanin content, and cell cycle traits. Studies of related genes in other species connect the family to thermotolerance, drought and chilling stress responses, pathogen resistance, trichome development, root meristem function, and floral organogenesis.
