SPL17 — Triticum aestivum

Summary

TaSPL17 (TRAESCS5A02G265900) on bread wheat chromosome 5A encodes an SBP-domain protein with sequence-specific DNA-binding and zinc-binding activity, localised to the nucleus. This gene is associated with ear development, flower development, fruit development, and regulation of secondary shoot formation, as well as upregulation of the vernalization response and activation of defence response to bacteria. It has been connected to ear number and bacterial disease resistance, and linked to growth, cell cycle, morphogenesis, and epigenetic regulation of gene expression. Studies of related genes in other species connect the family to tiller number, grain size, grain yield, plant height, root elongation, and bacterial blight disease resistance.
