    Abstract
    Root depth, as an important component of root architecture, plays a significant role in growth, grain yield determination and abiotic stress tolerance in crop plants, but its genetic basis remains poorly elucidated. In this study, a panel composed of 323 wheat accessions was assessed for variation in root depth and genotyped with the Wheat 660K SNP Array. GWAS detected significant association between a 125 bp miniature inverted‐repeat transposable element in the promoter of the TaVSR1‐B gene with root depth at the booting stage. We showed that the MITE repressed TaVSR1‐B...
