DA2 — Triticum aestivum

Summary

TRAESCS6A02G189300, designated TaDA2 (also known as TaGW2-6A), encodes a RING-type zinc finger protein with ubiquitin ligase activity, placing it in the Sip5/DA2 family on wheat chromosome 6A. The gene is associated with the regulation of seed size, organ growth, and starch anabolism, as well as protein ubiquitination and SCF-dependent proteasomal degradation. It has been linked to numerous agronomically important traits, including grain weight, grain length and width, grain number per spike, ear weight, spike length, plant height, peduncle length, tiller number, days to heading, grain filling period, flour and grain protein content, test weight, drought tolerance, and lodging resistance. Studies of related genes in other species connect the family to seed size, organ size, cell proliferation, and leaf senescence, as well as organ growth regulation.
