A collection of 110 isolates of Puccinia triticina in 2007 from different European wheat-growing regions were examined for their sensitivity to the demethylation inhibiting (DMI) fungicide epoxiconazole and the expression and mutations of the target gene, cyp51. The cyp51 gene was highly conserved across Europe. A mutation at codon 134 (Y134F) was identified in only five isolates. This mutation had a limited impact, if any, on the sensitivity of P. triticina towards epoxiconazole. Over the… CONTINUE READING
