PCR With Specific Primers for Detection of Rhizoctonia solani Anastomosis Groups Reveals Lack of Specificity

Journal of Phytopathology, Volume 173, Issue 5, September/October 2025.
ABSTRACT Several specific primers based on the internal transcribed spacer (ITS) region of rDNA have been used to discriminate anastomosis groups (AGs) and subgroups in Rhizoctonia solani, but the efficacy of these primers was not evaluated considering several known AGs.

Inter-Isolate Heterokaryosis in Thanatephorus Cucumeris I. Between Isolates of Similar Pathogenicity [PDF]

Australian Journal of Biological Sciences, 1972
Previous investigations in this laboratory of heterokaryosis in T. cucumeris have utilized mutant progeny of one field isolate. The work has now been extended to include four field isolates, of different geographic origin, yet of similar host specificity in their pathogenic reactions (viz.
