Abstract excerpt
Restriction and modification (R-M) systems are generally thought to protect bacteria from invasion by foreign DNA. This paper proposes the existence of an alternative role for the phase-variable R-M systems encoded by the hsd loci of Mycoplasma pulmonis. Populations of M. pulmonis cells that arose during growth in different environments were compared with respect to R-M activity and surface antigen production....
