Gene expression, adaptation to high osmolarity and glycerol accumulation 

In addition to the hyperosmolarity sensing MAP kinase, other upstream protein kinases in N. crassa, including the Os-1 histidine kinase, have been simi- 

In Botrytis, dicarboximide and phenylpyrrole resistant laboratory strains [12,18] and less sensitive field isolates [13, 19] are usually found to be mutated in Dafl, the histidine kinase homologous to Os-1. However, field isolates less sensitive to dicarboximide fungicides were reported to retain wild-type levels of sensitivity to phenylpyrroles [18-20]. Vignutelli et al. [21] crossed a field resistant strain of Botrytis with a sensitive one and found that dicarboximide resistance segregated separately from phenylpyrrole resistance, suggesting different genes regulate
