The new stresses found in new get across, 09Bc11 and you can B, differ from inside the fungicide sensitivity habits. Filter systems 09Bc11 is actually resistant against boscalid and you can iprodione, while B are responsive to both fungicides. Unwilling alleles segregated inside the an excellent Mendelian step one : 1 styles on the young ones (30R and you may 37S to help you iprodione; 37R and you will 30S in order to boscalid). Linkage are calculated between fungicide opposition characteristics and you can SNP alleles (Fig. 4). Boscalid resistance totally co-segregated (at the a frequency out of >97%) which have an individual non-synonymous SNP allele you to definitely mapped so you’re able to Chr1 around status 1 800 000, whereas iprodione resistance co-segregated (at a frequency off >97%) which have sixteen low-associated SNP alleles towards Chr1 up to reputation dos two hundred 000. Further study of this type of countries revealed that boscalid and you can iprodione resistance was indeed because of brand new identified H272R mutation regarding succinate dehydrogenase gene BcSdhB (Leroux mais aussi al., 2010 ) therefore the understood I365S mutation in the histidine kinase gene Bos1 (Leroux et al., 2002 ), correspondingly.
Mapping out of a couple of fungicide resistance loci in order to chromosome 1 (Chr1). New x-axis represents series assembly coordinates. The fresh new y-axis represents the subtraction out-of frequencies at which an individual nucleotide polymorphism (SNP) is found in respective fungicide resistant (R) minus painful and sensitive (S) vast majority.
