Abstract [en]

Arbuscular mycorrhizal (AM) fungi are important symbionts to most of the terrestrial plants. Recent genome sequencing projects revealed that many AM fungi have repetitive genetic elements in their genomes and among these repetitive genetic elements, cut-and-paste DNA transposable elements were very prevalent. For example, in Rhizophagus irregularis, up to 21% of the genome assembly content was associated with cut-and-paste DNA transposable elements. In Diversispora epigaea, up to 23% of the genome content can also be attributed to cut-and-paste DNA transposable elements. While cut-and-paste DNA transposable elements are very abundant in AM fungi, detailed studies on these repetitive elements have been lacking. In this study, we revealed the diversity of cut-and-paste DNA transposable elements in Claroideoglomus claroideum and identified many potentially autonomous transposable elements in the genome assembly of C. claroideum. The evolutionary relationship between the DNA transposons we identified and the established sequences in public databases were also investigated.
