An intron in the cytochrome <i>b</i> gene of <i>Monilinia fructicola</i> mitigates the risk of resistance development to QoI fungicides

Abstract

This is the first complete Cyt b gene sequence published for M. fructicola or any other Monilinia species, forming the basis for molecular analysis of QoI fungicide resistance. Sequence analysis revealed that the G143A mutation responsible for high levels of QoI fungicide resistance in many plant pathogenic fungi may not develop in M. fructicola unless genotypes emerge that lack the 1166 bp intron.
