From fungi to orchids: a tale of two horizontal gene transfer events.

Horizontal gene transfer (HGT), a process that involves the movement of DNA from one organism to another that does not belong to the same species (or form one genome to another in the same organism), is relatively common in bacteria, rare in eukaryotes, and even more uncommon between fungi and flowering plants. Surprisingly, two HGT events have been reported in orchids both from Ustilaginaceae, a family of smut fungi. Here, we inspected the mitogenome of 61 species and identified the taxonomic extent of the two HGT events in Orchidaceae. We estimated the timing of these events and characterized the fate of the genes that were transferred in the main clades of orchids. These results shed light on the understanding of the HGT phenomenon and the composition of the mitochondrial DNA in plants.
