“…Although only a few taxa from the present study were included in more recent phylogenies, the relationships found here were generally consistent with the findings of Steane et al (1999Steane et al ( , 2002Steane et al ( , 2011, for the relationship of Eucalyptus obliqua and E. regnans) and Bayly and Ladiges (2007, for the close relationship of E. triflora, E. spectatrix and E. paliformis). The results from the present study support many of the relationships proposed by Ladiges et al (1989), Hill (2002) and Brooker (2000).…”

“…The phylogenies produced here were more resolved than were previous phylogenies of subgenus Eucalyptus using traditional one-region sequence data (e.g. Steane et al 1999Steane et al , 2002Bayly and Ladiges 2007). These findings demonstrate that phylogenetic analyses based on DArT markers can provide insights into evolutionary relationships among Table 2 (Column 6).…”

“…In addition, closely related co-occurring taxa in subgenus Eucalyptus (sections Aromatica, Capillulus, Cineraceae and Longitudinales) were sampled (often from more than one individual per species from different locations). Eucalyptus cloeziana (subgenus Idiogenes) was included as an out-group to subgenus Eucalyptus on the basis of previous studies (Sale et al 1993;Hill and Johnson 1995;Ladiges et al 1995;Steane et al 1999;Udovicic and Ladiges 2000;Steane et al 2011 …”

Abstract. Eucalyptus is a genus that occurs in a range of habitats in Australia, Papua New Guinea, Timor, Sulawesi and the Philippines, with several species being used as sources of timber and fibre. However, despite its ecological and commercial significance, understanding its evolutionary history remains a challenge. The focus of the present study is the green ashes (subgenus Eucalyptus section Eucalyptus). Although previous studies, based primarily on morphology, suggest that the green ashes form a monophyletic group, there has been disagreement concerning the divergence of taxa. The present study aims to estimate the phylogeny of the green ashes and closely related eucalypts (37 taxa from over 50 locations in south-eastern Australia), using genome-wide analyses based on Diversity Arrays Technology (DArT). Results of analyses were similar in topology and consistent with previous phylogenies based on sequence data. Many of the relationships supported those proposed by earlier workers. However, other relationships, particularly of taxa within the Sydney region and Blue Mountains, were not consistent with previous classifications. These findings raise important questions concerning how we define species and discern relationships in Eucalyptus and may have implications for other plant species, particularly those with a complex evolutionary history where hybridisation and recombination have occurred.

“…Incongruence due to statistical, sampling or computational errors can be addressed by expanded and judicious sampling, addition of phylogenetic characters or by modifying analysis and tree reconstruction models (e.g., Steane et al, 1999Steane et al, , 2002Udovicic and Ladiges, 2000). However, if topological incongruence between morphological and molecular data have their origin in genealogical discordance, the conflict is not easily resolved by modifying the model used in phylogenetic reconstruction, correcting for sampling error, combining data or by other manipulations.…”

Microsatellites retain phylogenetic signals across genera in eucalypts (Myrtaceae)

The utility of microsatellites (SSRs) in reconstructing phylogenies is largely confined to studies below the genus level, due to the potential of homoplasy resulting from allele size range constraints and poor SSR transferability among divergent taxa. The eucalypt genus Corymbia has been shown to be monophyletic using morphological characters, however, analyses of intergenic spacer sequences have resulted in contradictory hypotheses-showing the genus as either equivocal or paraphyletic. To assess SSR utility in higher order phylogeny in the family Myrtaceae, phylogenetic relationships of the bloodwood eucalypts Corymbia and related genera were investigated using eight polymorphic SSRs. Repeat size variation using the average square and Nei's distance were congruent and showed Corymbia to be a monophyletic group, supporting morphological characters and a recent combination of the internal and external transcribed spacers dataset. SSRs are selectively neutral and provide data at multiple genomic regions, thus may explain why SSRs retained informative phylogenetic signals despite deep divergences. We show that where the problems of size-range constraints, high mutation rates and size homoplasy are addressed, SSRs might resolve problematic phylogenies of taxa that have diverged for as long as three million generations or 30 million years.
