Table 4 Incongruent patterns observed between nDNA and cpDNA
Population | Morphology-based species identification | Number of samples studied for cpDNA | Number of samples involved in the incongruence | cpDNA haplotype specific to: | nDNA characteristic of*: | Hypothesized evolutionary scenario (see text) |
|---|---|---|---|---|---|---|
Mt Do | A. biramulata | 19 | 18 | A. biramulata (H05 to H08) | A. montana-A. laubenfelsii | Introgression |
Mt Tonta | A. biramulata | 22 | 12 | A. rulei (H65) | A. biramulata | Introgression (or shared ancestral polymorphism) |
Pandop | A. montana | 5 | 3 | A. biramulata (H07) | A. biramulata | Erroneous species identification, which was revised to A. biramulata for population analyses |
2 | A. montana (H58) | A. biramulata | Introgression | |||
Paeoua | A. rulei | 13 | 1 | A. muelleri (H33); closer to A.montana-A. laubenfelsii haplotypes than to A. rulei ones | A. rulei | Introgression |
Ouinee | A. rulei | 16 | 1 | A. muelleri (H33); closer to A.montana-A. laubenfelsii haplotypes than to A. rulei ones | A. rulei | Introgression |
PinPin | A. rulei | 15 | 1 | A. montana (H53); but close (d = 1 change) to the abundant A. rulei haplotype H61 | A. rulei | Population-specific cpDNA haplotype |
Panie | A. montana | 10 | 3 | H64, retrieved with A. rulei haplotypes but close (d = 2 changes) to the common A. montana-A. laubenfelsii haplotype H52 | A. montana-A. laubenfelsii | Shared ancestral polymorphism |
Paeoua | A. montana | 16 | 1 | H11, retrieved with A. biramulata haplotypes | More related to A. montana-A. laubenfelsii than to A. biramulata | Shared ancestral polymorphism |
Mt Do | A. biramulata | 19 | 1 | A. scopulorum (H38) | A. montana-A. laubenfelsii | Shared ancestral polymorphism (at cpDNA) and introgression with A. montana-A. laubenfelsii |
Thio | A. scopulorum | 21 | 1 | A. columnaris and A. nemorosa (H01) | A. scopulorum | Insufficient data to propose an evolutionary scenario |
