Characterization of three-nucleate Rhizoctonia AG-E based on their morphology and phylogeny.

ABSTRACT: The genus Rhizoctonia has been classified into two main groups according to the number of nuclei. Binucleate Rhizoctonia strains have two nuclei in each cell, whereas multinucleate Rhizoctonia fungi were observed to have a variable number of nuclei ranging from 4 to 16 in each cell. In the study, twelve Polish isolates were tested. According to ITS1-5,8S-ITS2 rDNA sequences, the isolates were classified in the AG-E. Their affiliation to AG was confirmed by anastomosis reactions with tester isolates. The number of nuclei was counted with DAPI staining under a fluorescent microscope, and the diameter of the hyphae was also measured. Not all AG-E isolates had the same number of nuclei in their cells: one group among these fungi produced cells with a diverse number of nuclei, usually 3; howeve
