摘要: The fungus Magnaporthe oryzae is a serious pathogen of rice and other grasses. Telomeric restriction fragments in isolates that infect perennial ryegrass (prg) are hotspots for genomic rearrangement undergo frequent, spontaneous alterations during fungal culture. telomeres rice-infecting very stable by comparison. Sequencing chromosome ends from number prg-infecting revealed two related non-LTR retrotransposons (M. Retrotransposons or MoTeRs) inserted the telomere repeats. This contrasts with uninterrupted sequences. Genetic evidence indicates MoTeR elements responsible observed instability. MoTeRs represent new family telomere-targeted transposons whose members found exclusively fungi.
