Reconstruction of Phylogenetic Relationships of Larch Larix sukaczewii Dyl. Based on Chloroplast DNAtrnK Intron Sequences

To reconstruct the systematic relationships of larch Larix sukaczewiiwe used the chloroplast trnK intron sequences of L. decidua, L. sukaczewii, L. sibirica, L. czekanovskii, and L. gmelinii.Analysis of phylogenetic trees constructed using the maximum parsimony and maximum likelihood methods showed a clear divergence of the trnK intron sequences between L. sukaczewii and L. sibirica. This divergence reaches intraspecific level, which supports a previously published hypothesis on the taxonomic isolation of L. sukaczewii.
