Illegitimate and Homologous Rearrangements, an intricate relationship?

Participants : David P. Parsons, Guillaume Beslon, Carole Knibbe.

We have introduced homologous horizontal transfer in the aevol model. First results show that this process interacts in a complex way with both non-homologous transfer (that creates homologous sequences) and mutation rate (that destroys homologous sequences). We have shown that homologous transfer is useful only in strict conditions (small mutation rate and small - but non-null - non-homologous rate) [27] . This result confirms the genericity of the indirect selection mechanism we previously shown to be at the origin of scaling laws in genomes and transcriptomes [25] .
