Rhizoctonia solani: Mitotic Division in Vegetative Hyphae
Mohamed N. Shatla, J. B. Sinclair
American Journal of Botany, Vol. 53, No. 2 (Feb., 1966), pp. 119-123

Abstract
The mode of division in vegetative nuclei of an isolate of Rhizoctonia solani Kuhn, (Pellicularia filamentosa [Pat.] Rogers), from diseased cotton seedlings was studied with the aid of light and phase-contrast microscopy. The studies were made using the squash technique and refluxed aceto-carmine for staining. Observations showed that mitotic mode of division similar to that in higher plants was present and the haploid chromosome number was four at metaphase. These findings are discussed with respect to the modes of division proposed for vegetative nuclei in the fungi.

Abstract
Such characters as surface ultrastructure of asexual and sexual propagules, wall and septal ultrastructure, the fine structure of ascal tips, and ultrastructural aspects of nuclear division have taxonomic significance for major groups of fungi. Information derived from fine-structural analyses can be correlated with that obtained from light-microscopic, chemical, and developmental investigations. The versatility of electron-microscopic facilities makes them powerful research tools in the hands of the innovative taxonomist.

Abstract
The Rhizoctonia solani complex represents an economically important group of soilborne basidiomycete pathogens that occur on many plant species throughout the world (41). Identification and study of Rhizoctonia species has always presented a challenge because of their ill-defined taxonomy and our poor understanding of their natural history. Although identification of isolates as R. solani is largely dependent on vegetative characters, members of this group are known to be associated with a Thanatephorus teleomorph, or sexual stage. Several recent reviews discuss the taxonomy of different groups in Rhizoctonia (34,41,44). Although previous research has focused primarily on taxonomic characterization and identification of R. solani, very little information about their
population biology and genetics is available. In this paper, we
review some recent progress in understanding the population biology and genetics of fungi in the R. solani complex and discuss possible research avenues for investigating R. solani genetic diversity in natural populations.
