SARD1 — Triticum aestivum

Summary

TRAESCS3D02G041800 (symbol SARD1, also known as TaSARD1-3D) on bread wheat chromosome 3D encodes a calmodulin-binding protein belonging to the CBP60 family and is annotated as a sequence-specific DNA-binding transcription factor. The gene is associated with regulation of salicylic acid biosynthesis, systemic acquired resistance, and defense responses to bacteria, oomycetes, and nematodes. It is linked to negative regulation of leaf senescence, cell size control, wax anabolism, and responses to UV-B and abiotic stimuli. The encoded protein localizes to both the cytoplasm and nucleus. Trait associations include coleoptile length, heading time, grain protein content, spike length, tiller number, grains per spike, leaf chlorophyll content, net photosynthetic rate, stem rust and powdery mildew disease responses, nitrate sensitivity, and root and shoot dry weight. Related genes in other species link the family to plant immunity, salicylic acid production, and leaf growth.
