Abstract
Rhizoctonia solani is a soil-borne basidiomycete fungus with a necrotrophic lifestyle being classified into fourteen reproductively incompatible anastomosis groups (AGs). AG3-PT (a potato subgroup) is associated with quantitative and qualitative yield losses through stem canker and black scurf in potato. Here we present the first draft sequence of the R. solani [AG3-PT] strain RS-20 with a G-C content of 48.3%. It consists of 11,431 total predicted protein coding regions including 181 tRNA and 31 rRNA coding genes. The initial pBLAST revealed more than 97% hits among AG groups where as only 1.7% of genes hit with other organisms. The R. solani genome is found to be dominated with tri mer repeats. The genome-wide evolutionary studies revealed the close association of AG3-PT with AG3. The draft sequence represents a helpful resource not only for understanding the core genes involved in pathogenecity but also evolution and adaptive behaviour within the R. solani species complex.
