Phylogeny and estimated genetic divergence times of banana cultivars (Musa spp.) from Java Island by maturase K (matK) genes
The size of PCR-amplified matK ranged from 844 to 860 bp and showed a high variability. The haplotype diversity was 0.9048 with nine haplotypes. Haplotype distribution map revealed the lineage patterns of banana cultivars from Java. Reconstruction of genetic relationships using the maximum likelihoo...

| Tóm tắt: | The size of PCR-amplified matK ranged from 844 to 860 bp and showed a high variability. The haplotype diversity was 0.9048 with nine haplotypes. Haplotype distribution map revealed the lineage patterns of banana cultivars from Java. Reconstruction of genetic relationships using the maximum likelihood, maximum parsimony and Bayesian inference algorithms produces tree topologies and classifications that are grouped according to their genomic groups, into three main clades, i.e., AA/AAA, AAB and ABB. Based on the previously derived age constraints and fossil data, we estimate (Musaceae) that genetic divergence times of all samples occurred during the Eocene (95% HPD: 51.9 Mya), Musa acuminata group (AA, AAA, AAB) with Musa balbisiana group (BB and ABB) occurred during the Oligocene (95% HPD: 26 Mya), and the separation on each banana cultivars occurred during the Middle Miocene to Pliocene (95% HPD: 16.5–2.5 Mya). |
