abstract：:A new alginate regulatory gene, algQ, was identified in a chromosomal region which, when tandemly amplified, induces mucoidy in Pseudomonas aeruginosa. The algQ gene was found closely linked to the previously identified algR gene. Both algQ and algR were required for transcription of the key alginate biosynthetic gene...
