sentence: Inactivation of tpbA altered diverse loci including genes related to EPS production ( pelACDF induced approximately 4-fold ) , transport ( PA2204 repressed approximately 5-fold , PA4142 – PA4143 induced approximately 3-fold ) , type IV pili ( PA4302 to PA4306 repressed approximately 4-fold ) , and a putative adhesin and its regulator ( PA4624 – PA4625 induced approximately 4-fold ) ( Tables S1 and S2 ) .
