SPL17 — Triticum aestivum

Summary

TRAESCS5D02G273900, designated TaSPL17 on bread wheat chromosome 5D, encodes a protein containing an SBP domain with DNA-binding transcription activator activity. The gene is associated with ear development, flower development, fruit development, and the regulation of secondary shoot formation. It has been connected to growth, cell growth, morphogenesis, and cell organisation, as well as to phenylpropanoid and carbohydrate metabolism, coumarin anabolism, lignin anabolism, and secondary cell wall biogenesis. TaSPL17 is linked to the upregulation of the vernalization response, activation of defence response to bacteria, and response to wounding. The encoded protein localises to the nucleus. Studies of related genes in other species link the family to grain size, grain yield, tiller number, plant height, and bacterial blight disease resistance.
