DA2 — Triticum turgidum subsp. durum

Summary

TRITD6AV1G091060 (TtDA2) encodes a RING-type domain-containing protein with ubiquitin ligase activity and zinc binding capability. This gene is associated with the regulation of seed size, organ growth, and cell division, as well as amylopectin and starch anabolism, protein ubiquitination, and NO storage. It has been linked to grain weight, grain size, grain yield, amylose content, starch content, protein content, and grain filling period. Associations also include cold stress response, lodging resistance, pathogen resistance, senescence, and nutritional quality. Studies of related genes in other species connect this family to seed size, organ size, cell proliferation, leaf senescence, and additional traits such as grain width, grain length, spikelet number, tiller number, heading time, and flour protein content.
