Abstract
Abstract Molecular markers have allowed important advances in the understanding of the genetics, evolution and conservation of Eucalyptus. Eucalyptus is an ecologically and economically important Australian genus of over 700 species, some of which are used worldwide in plantation forestry. Until recently, the average number of molecular markers available for Eucalyptus was limited to sub-genomic levels with at most, a few hundred markers per study. Furthermore, the transferability of markers across species and pedigrees was usually very limited. We here discuss the development and benefits of a genus-wide DArT genotyping array for use in Eucalyptus and results from studies using these markers. This DArT array allows high throughput genotyping, combined with genome wide coverage and high transferability across species.
