Phylogenetics of 20 Species ofEucalyptus Based on Sequences of the Chloroplast matK Gene
With the enrichment of public databases, the release ofEucalyptus genome sequence data has gradually been increasing. In this study, 21Eucalyptus chloroplastmatK gene sequences were downloaded from the NCBI database for analytical use. Depending on the software used, we found the phylogenetic trees obtained could differ from the morphological taxonomic status according to Hill & Johnson, which is accepted as the academic standard. These differences might relate to the sequence data not being comprehensive, as the amount of information obtained can't represent the entire genome sequence. When phylogenetic trees constructed from the MP method, the ML method, the NJ method, the UPGMA method and the Bayes method were compared to the results of sequence information site analysis and the morphological classification status, the results showed that the phylogenetic tree constructedfrom UPGMA method was consistent with the sequence information site analysis results, and the phylogenetic tree constructed from MP method was more credible. However, further information needed to confirm these results will require follow-up studies.
