Popis: | Sequence analysis of the cytochrome b gene of Guignardia bidwellii showed that the occurrence of the most important resistance mechanism for QoI fungicides, the G143A mutation, is relatively unlikely. This is due to the presence of an intron directly after codon 143. A mutation in this codon (from glycine to e.g. alanine) would presumably lead to incorrect mRNA maturation and a non-functional, lethal protein. Intron sequences have not been detected in immediate vicinity to the codons 129 and 137; therefore, the occurrence of those two mutations cannot be excluded. Since the effects of these mutations on field performance on QoI fungicides are rather low, the overall resistance risk of G. bidwellii to this fungicide class is estimated to be low. |
