De novoAssembly and Comparative Analyses of Mitochondrial Genomes in Piperales

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 A complete mitochondrial genome was assembled for Saururus.

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.

Observation Five populations had a single genotype.

Observation More than 73% of ISSR diversity occurred across populations.
Observation About 27% of ISSR diversity occurred within populations.
Observation Only two populations displayed novel loci, with one and three loci respectively.
Association ISSR differentiation among populations was uncorrelated with geographic distance on Masatierra.
Observation ISSR variation followed a mosaic pattern.
Association Differentiated local populations accord with the geitonogamous breeding system and suggest low long distance dispersal.
Mechanism The mosaic ISSR pattern may partly result from drift and inbreeding after habitat fragmentation.
Mechanism Mutation and rare gene flow could contribute to the mosaic variation and scarcity of unique alleles.
Observation Plants occurred in dense forest understory.
Observation Plants also occurred in full sunlight in forest openings.
