Rhizoctonia solani may be a plant infective plant with a good host vary and worldwide distribution. it absolutely was discovered over a hundred years agone. R. solani ofttimes exists as thread-like growth on plants or in culture, and is taken into account a soil-borne infectious agent.
The basidiomycete Rhizoctonia solani Kühn (teleomorph: Thanatephorus cucumeris (Frank) Donk) is well-known as a plant pathogenic fungus causing economically vital diseases to many agricultural and husbandry crops worldwide (Ogoshi 1987; Sneh et al. 1991; 1996). Species in Rhizoctonia in general aren't well understood thanks to the absence of distinct morphological options and since of the shortage of knowledge concerning union and union relationships (Vilgalys and Cubeta 1994). supported hyphal conjugation reactions, isolates of R. solani are divided into conjugation teams (AGs), of that fourteen AGs are delineated (Sneh et al. 1991, 1996; Carling et al. 1999a,b, 2002). The AGs appear to be genetically isolated and R. solani is regarded an oversized species complicated composed of the many genetically distinct teams with terribly numerous life histories, doubtless comprising many species (Anderson 1982; Kuninaga 1996; Vilgalys and Cubeta 1994; Cubeta and Vilgalys 1997). However, the teams can not be distinguished by their sexual stages as a result of the lack of the many isolates to fruit in culture, that is that the reason why most researchers recognize R. solani as one species divided into Ags and AG subgroups (Ogoshi 1987).
Rhizoctonia solani, the foremost widely known species of Rhizoctonia was originally delineated by Julius Kühn on potato in 1858. Rhizoctonia solani is a fungus plant that doesn't manufacture any parthenogenetic spores (called conidia) and solely often can the plant manufacture sexual spores (basidiospores). In nature, R. solani reproduces asexually and exists primarily as vegetative mycelium and/or sclerotia. in contrast to several fungus fungi, the basidiospores aren't penned in a very fleshy, plant organ or mushroom. The sexual mature structures and basidiospores (i.e. teleomorph) were 1st discovered and delineated very well by Prillieux and Delacroiz in 1891. The sexual stage of R. solani has undergone many name changes since 1891, however is currently familiar as Thanatephorus cucumeris.
