Un nouvel algorithme pour la detection des transferts horizontaux de genes partiels entre les especes et pour la classification des transferts inferes
In this article we are describing a new algorithm for detecting and validating partial horizontal gene transfers (HGT). The presented algorithm is based on a sliding window procedure which analyzes fragments of the given multiple sequence alignment. A bootstrap procedure incorporated in our method can be used to estimate the support of each inferred partial HGT. The new algorithm can be also applied to confirm or discard complete (i.e., traditional) horizontal gene transfers detected by any HGT inferring algorithm. While working on a full-genome scale, the introduced algorithm can be used to assess the level of mosaicism of the whole species genomes as well as the rates of complete and partial HGT underlying the evolution of the considered set of species.
