Genomic patterns of species diversity and divergence in Eucalyptus
Corey J. Hudson, Jules S. Freeman, Alexander A. Myburg, Brad M. Potts, and René E. Vaillancourt
We examined genome-wide patterns of DNA sequence diversity and divergence among six species of the important tree genusEucalyptus and investigated their relationship with genomic architecture.
Using c. 90 range-wide individuals of each Eucalyptus species (E.grandis, E. urophylla, E. globulus, E. nitens, E. dunnii and E. camaldulensis),
genetic diversity and divergence were estimated from 2840 polymorphic
diversity arrays technology markers covering the 11 chromosomes. Species
differentiating markers (SDMs) identified in each of 15 pairwise
species comparisons, along with species diversity (HHW) and divergence (FST), were projected onto the E. grandis reference genome.
