The introduction of mutations in either of rtsAB contributed to reduced invasion gene expression in the these genes reduced hilA expression in both relA spoT strain , we examined the effects of both mutations relA spoT strains , indicating that the loss of hilA expression and overexpression of RtsA/B on the expression in the relA spoT strain was not due to repression by these of a hilA-lacZ fusion in relA spoT strains .
