Neighbor joining tree of the phage integrase gene of as intact predicted prophages in L. sakei strains. Bootstrap values are based on a Jukes-Cantor model (1000 replicates). The integrases of phages infecting other lactobacilli were included as outgroups. For the assignment of groups based on the genomic integration sites, only Latilactobacillus sakei phage integrases have been taken into account
