The genome sequence and gene predictions of Rhizoctonia solani were not determined by the JGI, but were provided by Daniel Wibberg (dwibberg@cebitec.uni-bielefeld.de) and have been published (Daniel Wibberg et al., 2013). Please note that this copy of the genome is not maintained by the author and is therefore not automatically updated.

The fungus Rhizoctonia solani (teleomorph Thanatephorus cucumeris) is responsible for many economically important plant diseases worldwide (Sneh et al., 1996). Donk (1956) initially proposed to designate the genus Thanatephorus as the teleomorphic phases of the R. solani multinucleate anamorph. It is generally accepted that the genus applies to most parasitic fungi like R. solani considered as a very destructive plant pathogen (González-Garcia et al., 2006). R. solani is a species complex of genetically distinct fungi groups in the cantherelloid clade of the phylum Basidiomycota (Binder et al., 2005).

As a fundamentally asexual fungus the anamorph R. solani does not reproduce sexually (Adams, 1996). The pathogen survives and disseminates in form of sclerotia and/or vegetative mycelia (Keijer et al., 1996). However, Rhizoctonia species are strong saprophytes and able to survive in the absence of host plants by feeding on organic matter (Sneh et al., 1996). In general, the infection process of R. solani includes adhesion, penetration, colonization, and host reaction. Isolates of the fungus infect a host plant mostly by formation of infection cushions on rice (Matsuura, 1986).
