Runxian Yu; Xudong Chen; Lingjie Long; et al. Genome Biology and Evolution 2023. doi:10.1093/gbe/evad041
Other claims from this paper (13)
- Method / resource Nine new mitochondrial genomes representing perianth-bearing Piperales and a sister-clade member were assembled.
- Method / resource Three complete or nearly complete mitochondrial genomes were obtained from Aristolochiaceae.
- Method / resource A complete mitochondrial genome was assembled for Saururus.
- Observation Aristolochia had many more short mitochondrial repeats than other angiosperms.
- Observation Approximately 30% of repeats under 350 bp could mediate recombination.
- Observation Perianth-bearing Piperales mitochondrial genomes had conserved protein-coding gene repertoires.
- Observation Perianth-bearing Piperales mitochondrial genomes varied in tRNA gene copy number.
- Observation Group II introns nad1i728, cox2i373 and nad7i209 shifted from cis to trans splicing.
- Observation A cox1 region was likely derived from an independent horizontal transfer.
- Observation An atp8 region was likely derived from an independent horizontal transfer.
- Observation Specific substitution types were enriched in different magnoliid lineages.
- Observation Aristolochiaceae had the highest A:T > T:A substitution ratio among investigated angiosperms.
- Method / resource The study reports the first mitochondrial genomes for Piperales.
