Other claims from this paper (6)
- Observation Phylogenetic and comparative genomic analyses uncovered extensive HGT from Fagaceae hosts in M. yamamotoi, affecting coding and non-coding regions
- Observation Almost 60% of the M. yamamotoi mtDNA is of foreign origin
- Observation Seven M. yamamotoi chromosomes are entirely foreign, with structural signatures consistent with circle-mediated HGT
- Observation Six protein-coding genes in the M. yamamotoi mtDNA are of foreign origin
- Observation One chimeric gene was detected in the M. yamamotoi mtDNA
- Observation A foreign atp1 gene has replaced the missing native copy in M. yamamotoi, a rare functional HGT in plant mitochondria
