The choice of the molecular target still remains a problem because too few comparative data are available. This is particularly true for hybrid taxa, where differential introgression of genome parts leads to incongruity between data sets. We have studied the potential of three data partitions to reconstruct the phylogeny of mints related to M. x piperita. These included nuclear DNA (ITS), chloroplast DNA (non-coding regions trnL intron, intergenic spacers trnL-trnF, and psbA-trnH), and AFLP and ISSR, markers. The taxonomic sampling was composed of hybrids, diploid and polyploid genomes. Since the genealogy of cultivated mint hybrids is known, they represent a model group to compare the usefulness of various molecular markers for phylogeny inference. Incongruities between ITS, chloroplast DNA, and AFLP-ISSR phylogenetic trees were recorded, although DNA fingerprinting data were congruent with morphological classification. Evidence of chloroplast capture events was obtained for M. x piperita. Direct sequencing of ITS led to biased results because of the existence of pseudogenes. Sequencing of cloned ITS further failed to provide evidence of the existence of the two parental copy types for M. x piperita, a sterile hybrid that has had no opportunity for concerted evolution of ITS copies. AFLP-ISSR data clustered M. x piperita with the parent that had the largest genome. This study sheds light on differential of introgression of different genome regions in mint hybrids.10aDNA: Plant10aHaplotypes10aMentha10aMentha piperita10aPhylogeny10aPolymorphism: Genetic10aPseudogenes1 aGobert, V1 aMoja, S1 aTaberlet, P1 aWink, M  uhttps://lamiaceae.myspecies.info/content/heterogeneity-three-molecular-data-partition-phylogenies-mints-related-m-x-piperita-mentha01865nas a2200181   4500008004100000245007900041210006900120260000800189300001600197490000700213520134500220653002201565100001401587700001201601700001401613700001601627856004001643       2002                        eng d00aHybridization in the Section Mentha (Lamiaceae) Inferred from AFLP Markers0 aHybridization in the Section Mentha Lamiaceae Inferred from AFLP  cDec  a2017–20230 v893 aThe amplified fragment length polymorphism (AFLP) method was used to evaluate genetic diversity and to assess genetic relationships within the section Mentha in order to clarify the taxonomy of several interspecific mint hybrids with molecular markers. To this end, genetic diversity of 62 Mentha accessions from different geographic origins, representing five species and three hybrids, was assessed. Three EcoRI/MseI AFLP primer combinations generated an average of 40 AFLP markers per primer combination, ranging in size from 50 to 500 base pairs (bp). The percentage of markers polymorphic ranged from 50% to 60% across all accessions studied. According to phenetic and cladistic analysis, the 62 mint accessions were grouped into two major clusters. Principal coordinates analysis separated species into well-defined groups, and clear relationships between species and hybrids could be described. Our AFLP analysis supports taxonomic classification established among Mentha species by conventional (morphological, cytological, and chemical) methods. It allows the assessment of phenetic relationships between species and the hybrids M. spicata and M. x piperita, largely cultivated all over the world for their menthol source, and provides new insights into the subdivision of M. spicata, based for the first time on molecular markers.10aGenetic Diversity1 aGobert, V1 aMoja, S1 aColson, M1 aTaberlet, P  uhttp://www.jstor.org/stable/412275602156nas a2200289   4500008004100000245007900041210006900120260000800189300001600197490000700213520134500220653000901565653002301574653002201597653001801619653001401637653001001651653001101661653001401672653000901686653000901695100001401704700001201718700001401730700001601744856010601760       2002                        eng d00aHybridization in the section Mentha (Lamiaceae) inferred from AFLP markers0 aHybridization in the section Mentha Lamiaceae inferred from AFLP  cJan  a2017–20230 v893 aThe amplified fragment length polymorphism (AFLP) method was used to evaluate genetic diversity and to assess genetic relationships within the section Mentha in order to clarify the taxonomy of several interspecific mint hybrids with molecular markers.
