Abstract

Six circular mitochondrial genomes of multi-, bi-, and uninucleate Rhizoctonia isolates were assembled and found that all the genomes contain 14 conserved protein-coding genes, one ribosomal protein (rps3), and 23 tRNA in the same order. The mitogenome sizes of uninucleate isolates were relatively smaller than binucleate and multinucleate stains. The size variations between uninucleate and multinucleate isolates were from both intergenic and intronic regions, whereas the differences between uninucleate and binucleate isolates were predominantly from intergenic regions. The phylogenetic analysis revealed that Rhizoctonia strains of the same nucleate types had a closer relationship.

Keywords: Rhizoctonia; basidiomycota; mitogenome.
