ATL1 — Triticum aestivum

Summary

TRAESCS7D02G252300 (TaATL1) on wheat chromosome 7D encodes a RING-type E3 ubiquitin transferase of the ATL1/ATL16-like family, with annotated dual-specificity protein kinase and MEKK activity. The gene is associated with regulation of defence response to bacteria, salicylic acid-mediated signalling, systemic acquired resistance, the stress-activated MAPK cascade, and apoptotic processes. It has been linked to flowering time in wheat and to traits including grain iron and zinc content, grain yield, harvest index, test weight, plant vigour, stand establishment, stem rust and powdery mildew disease response, drought sensitivity, leaf chlorophyll content, net photosynthetic rate, and quantum yield. Localisation evidence connects the product to the TGN transport vesicle membrane, early endosome, ER, and plasmalemma. Related genes in other species are linked to enhanced disease resistance, dwarfing, spontaneous lesions, and nonhost resistance.
