New alleles of the wheat domestication gene Q reveal multiple roles in growth and reproductive development

Greenwood, Julian; Finnegan, E. Jean; Watanabe, Nobuyoshi; Trevaskis, Ben; Swain, Steve M

Description

The advantages of free threshing in wheat led to the selection of the domesticated Q allele, which is now present in almost all modern wheat varieties. Q and the pre-domestication allele, q, encode an AP2 transcription factor, with the domesticated allele conferring a free-threshing character and a subcompact (i.e. partially compact) inflorescence (spike). We demonstrate that mutations in the miR172 binding site of the Q gene are sufficient to increase transcript levels via a reduction in...[Show more]
