Biology, survival and mating genes of Cylindrocladium buxicola.

A new fungus, Cylindrocladium buxicola, which can cause a severe disease on boxwood (Buxus spp.), was recently observed in North America. The fungus was positively identified by DNA sequence comparisons as the cause of box blight. Whole boxwood plants required wounding for successful infection. In field studies, survival of C. buxicola in Southern Ontario was low after the winter, but inoculum retained viability throughout the fall. Whole genome sequencing of two C. buxicola isolates revealed the presence of the MAT1-1 gene in an European isolate and MAT1-2 in a North American isolate, implying the possibility for sexual reproduction. The origin and introduction of this pathogen into North America is not known, but it is suspected of having been introduced by nursery stock.
