Draft genome sequence of the potato pathogen Rhizoctonia solani AG3-PT isolate Ben3.

ABSTRACT

The basidiomycetes fungus Rhizoctonia solani AG3 is responsible for black scurf disease on potato and occurs in each potato growing area world-wide. In this study, the draft genome sequence of the black scurf pathogen R. solani AG3-PT isolate Ben3 is presented. The genome sequence of R. solani AG3-PT isolate Ben3 consists of 1385 scaffolds. These scaffolds amount to a size of approx. 51 Mb. Considering coverage analyses of contigs, the size of the diploid genome was estimated to correspond to 116 Mb. Gene prediction by applying AUGUSTUS (3.2.1.) resulted in 12,567 identified genes. Based on automatic annotation using GenDBE, genes potentially encoding cellulases and enzymes involved in secondary metabolite synthesis were identified in the R. solani AG3-PT isolate Ben3 genome. Comparative analyses including the R. solani AG3 isolate Rhs1AP, also originating from potato, revealed first insights into core genes shared by both isolates and unique determinants of each isolate.
