DA1 — Triticum aestivum

Summary

TRAESCS5B02G071300, designated TaDA1 on bread wheat chromosome 5B, encodes a LIM zinc-binding domain-containing protein belonging to the DA1-like family, with ubiquitin-binding and hydrolase activities. This gene is associated with the regulation of post-transcriptional gene silencing, inhibition of RNAi, glucuronoxylan anabolism, and regulation of DNA re-duplication. TaDA1 has been connected to grain number, grain size, and grain weight traits. Related genes in other species link the DA1 family to similar processes. The gene is also linked to meiotic co-expression patterns.
