Coffea dactylifera phylogenetic analysis
We sampled wild Coffea dactylifera from DR Congo and performed a phylogenetic analysis alongside with 21 other coffee species. DNA extractions were sent to Diversity Arrays Technology (Canberra, Australia). A consensus phylogenetic tree was constructed using ASTRAL-III, based on DArTseq polymorphic genetic markers. C. dactylifera was identified as a sister species to C. anthonyi within the “Coffea eugenioides-group” of the AFR-subclade.
