Abstract
A set of over 8000 Diversity Arrays Technology (DArT) markers developed for genomic studies of Eucalyptus was tested for its utility in population and phylogenetic studies. Small-scale population studies of E. camaldulensis, E. cladocalyx, E. globulus, E. grandis, E. nitens, and E. urophylla (from subgenus Symphyomyrtus) and E. pilularis (subgenus Eucalyptus) demonstrated the potential of DArT markers to differentiate species, identify interspecific hybrids and resolve biogeographic disjunctions within species. Phylogenetic reconstruction of 94 eucalypt species using the DArT markers was largely congruent with traditional taxonomy and ITSbased phylogenies, but provided greater resolution. DArT offers high-throughput genome-wide genotyping suitable for population genetic, phylogenetic and evolutionary studies across the full range of Eucalyptus species.
