Chloroplast genome analysis of Australian eucalypts - Eucalyptus, Corymbia, Angophora, Allosyncarpia and Stockwellia (Myrtaceae)

Abstract

We present a phylogenetic analysis and comparison of structural features of chloroplast genomes for 39 species of the eucalypt group (genera Eucalyptus, Corymbia, Angophora, and outgroups Allosyncarpia and Stockwellia). We use 41 complete chloroplast genome sequences, adding 39 finished-quality chloroplast genomes to two previously published genomes. Maximum parsimony and Bayesian analyses, based on *7000 variable nucleotide positions, produced one fully resolved phylogenetic tree (35 supported nodes, 27 with 100% bootstrap support). Eucalyptus and its sister lineage Angophora+. Corymbia show a deep divergence. Within Eucalyptus, three lineages are resolved: the 'eudesmid', 'symphyomyrt' and..
