Synteny analysis is combined with sequence similarity and motif identification to trace the evolution of the putative monocarboxylate (lactate/pyruvate) transporters Jen1p and the dicarboxylate (succinate/fumarate/malate) transporters Jen2p in Hemiascomycetes yeasts and Euascomycetes fungi. It is concluded that a precursor form of Jen1p, named here preJen1p, arose by the duplication of an ancestral Jen2p, during the speciation of Yarrowia lipolytica, which was transferred into a new syntenic context. The Jen1p transporters differentiated from preJen1p in Kluyveromyces lactis, before the Whole Genome Duplication (WGD), and are conserved as a single copy in the Saccharomyces species. In contrast, the ancestral Jen2p was definitively lost just prior to the WGD and is absent in Saccharomyces.
