An osmosensing histidine kinase mediates dicarboximide fungicide resistance in Botryotinia fuckeliana (Botrytis cinerea)

Field strains of Stemphylium vesicarium with a resistance to dicarboximide fungicides correlated with changes in a two-component histidine kinase

“…This observation was consistent with the findings of other authors who were able to observe cross-resistance between dicarboximides and phenylpyrroles only in B. cinerea and N. crassa laboratory mutants with high resistance to dicarboximides (Fujimura et al 2000;Ochiai et al 2001;Leroux et al 2002;Oshima et al 2002;Cui et al 2002, Cui et al 2004 or in A. alternata (Dry et al 2004) and A. brassicicola (Avenot et al 2005) highly resistant field isolates. In B. cinerea field isolates with moderate-low dicarboximide resistance (Leroux et al 2002), no cross-resistance was observed between dicarboximides and phenylpyrroles, as in S. vesicarium S + and R 1 phenotypes.…”

Nested PCR‐RFLP is a high‐speed method to detect fungicide‐resistant Botrytis cinerea at an early growth stage of grapes

“…There was agreement between the results of DNA sequence analysis of the genes responsible for the fungicide resistance in the present isolates (Fig. 2) and those of previous reports 13, 16, 17. This suggests that a single base mutation in the genes in B. cinerea isolated from vineyards confers resistance to these fungicides.…”

“…The authors collected B. cinerea isolates from vineyards in the 2006 and 2007 growing seasons and determined their sensitivity to fungicides (Table 1). The mechanisms of resistance to these fungicides have been reported previously 5, 9, 13, 16, 17. There was agreement between the results of DNA sequence analysis of the genes responsible for the fungicide resistance in the present isolates (Fig.…”

Exploring mechanisms of resistance to dimethachlone in Sclerotinia sclerotiorum

“…This result is consistent with results observed for dicarboxamide‐resistant isolates of S. sclerotiorum or other pathogens, e.g. DCF‐resistant isolates of B. cinerea , N. crassa and M. fructicola . However, other studies showed that dimethachlone‐insensitive field isolates did not grow more slowly under osmotic pressure .…”
