GID1 — Triticum aestivum

Summary

TRAESCS1A02G255100, designated TaGID1 on wheat chromosome 1A, encodes a protein with an alpha/beta hydrolase fold and carboxylesterase activity that also binds gibberellin. The gene is associated with gibberellin-mediated signalling, the transport of the GA-GID1 complex to the nucleus, and the subsequent degradation of DELLA repressors. TaGID1 has been connected to a wide range of traits, including stem length, plant vigor, grain iron and zinc content, test weight, seed set percent, stand establishment, and leaf area. It is also linked to responses to light quality, blue and UV light, temperature stress, drought, and wheat powdery mildew and stem rust. Additional associations include floral organ morphogenesis, regulation of leaf morphogenesis, and auxin biosynthesis.
