Anastomosis groups of Rhizoctonia solani associated with soybean root and hypocotyl rot in Ontario and resistance of accession PI 442031 to different anastomosis groups

Canadian Journal of Plant Pathology, 2005
Rhizoctonia solani is a complex species and causes soybean root and hypocotyl rot worldwide. Identifying anastomosis groups (AGs) prevalent in a region and growing cultivars with resistance specific to those AGs is a potential means to minimize economic losses from this disease. The main objectives of this study were (i) to identify the predominant AGs

Characterization of Anastomosis Group-10 (Ag-10) of Rhizoctonia Solani.

Australasian Plant Pathology, 1995
Isolates of Rhizoctonia solani AG-10 have been collected at low frequency from wheat and barley roots in Washington and Oregon. In Western Australia, AG-10 is collected regularly, but at low frequency, from the roots of cereal, lupin and pasture species. In this study all attempts to induce AG-10 to sporulate were unsuccessful. However, earlier studies

Grouping in Rhizoctonia Solani by Hyphal Anastomosis Reaction

1996
Grouping of strains of Rhizoctonia solani Kuhn (teleomorph: Thanatephorus cucumeris [(Frank) Donk] based on hyphal anastomosis reactions has been described as the principle most helpful to plant pathologists in studies of R. solani during a 15 year period beginning in 1965 (Anderson, 1982).

Use of DAPI for Anastomosis Group Typing of Strains of the Fungus Rhizoctonia solani

Biotechnic & Histochemistry, 1995
Strains of Rhizoctonia solani, a common soil-borne, pathogenic fungus of plants, are assigned to one of 11 anastomosis groups (AGs) based on the occurrence of imperfect fusions (anastomoses) between hyphae of a non-typed strain and a tester strain of one of the 11 AG's.

Genetic variation and pathogenicity of anastomosis group 2 isolates of Rhizoctonia solani in Australia

Mycological Research, 2007
A collection of isolates of Rhizoctonia solani anastomosis group (AG) 2 was examined for genetic diversity and pathogenicity. Anastomosis reactions classified the majority of isolates into the known subgroups of AG 2-1 and AG 2-2 but the classification of several isolates was ambiguous. Morphological characters were consistent with the species, with no

[Ultrastructural analysis of anastomosis group 9 of Rhizoctonia solani].

Acta cientifica venezolana, 1998
The ultrastructure of R. solani AG-9 (S-21, ATCC 62804) was investigated with transmission electron microscopy (TEM). The most important characteristics were those related with cell wall thickness, cytoplasmic matrix composition, number of nuclei and nucleoli and secretory material production.

Genetic diversity, anastomosis groups and virulence of Rhizoctonia spp. from strawberry

European Journal of Plant Pathology, 2007
Virulent Rhizoctonia spp. isolated from strawberry in Israel belonged to anastomosis groups (AG) of: binucleate Rhizoctonia (BNR) AG-A, AG-G, AG-K and AG-F, and to multinucleate Rhizoctonia (MNR) AG 4 subgroup HG-I. In addition, a soil isolate of AG 4 subgroup HG-III was also found to be virulent on strawberry.

Heterogeneity in electrophoretic karyotype within and between anastomosis groups of Rhizoctonia solani

Mycological Research, 1996
Isolates of the soil-borne basidiomycete Rhizoctonia solani vary in cultural appearance, in growth characteristics and in pathogenicity towards plants. Isolates of R. solani can be divided into anastomosis groups (AGs) and this division accommodates part of the observed diversity.

Anastomosis Groups and Pathogenicity of Rhizoctonia Solani Isolates From Tobacco in Italy

1997
Within Rhizoctonia solani the identification of anastomosis groups (AGs) as taxonomic infraspecific groups has become prevalent in recent years since they must be considered biological species. This differentation has been repeatedly confirmed by biochemical and molecular assays, such as isozyme analysis, DNA-DNA hybridization and RFLPs.
