In the flagella of gram negative bacteria there are 4 rings i.e; L,P,S & M whereas in flagella of gram positive bacteria there are only 2 rings i.e; S & M. Right? My question is if there is peptidoglycan layer present in gram positive bacteria, why doesn't it bear P ring as peptidoglycan layer of gram negative bacteria does?
