We defined putative imports for each branch of the ClonalFrame tree as a genomic region for which the probability of recombination never goes below 80% and reaches 95% in at least one site. Such putative imported DNA segments were extracted from each of the genomes and, for each of them, we searched the GenBank nucleotide database for similarities with the highest normalized BLASTN score along with a percent identity (pcident) of at least 95% in the whole nucleotide BLAST database (updated February, 2016).
