MAP1LC3A and infection: Each of these lysogens exhibits a phage-resistance phenotype mediated through repressor-mediated superinfection immunity (LC3, TP901-1, Dub35A) [32], superinfection exclusion of heterologous phages (LC3, TP901-1) [13,14], or other phage-resistance mechanisms such as potential abortive infection systems (Dub35A).
