Abstract
- The locations of two mutations that prevent adhesion of Pseudomonas fluorescens Pf0-1 to sand columns and seeds (adn, adhesion) were identified. Both lie in a single gene showing homology to the NtrC/NifA family of transcription activators. The predicted 55 kDa protein encoded by adnA is most closely related to activators involved in expression of flagellar proteins, consistent with the lack of flagella in adnA strains. Constitutive adnA expression restored motility and adhesion to an adnA strain, demonstrating that the observed phenotypes are due to lack of AdnA and not a consequence of other mutations or polar effects of mutations in adnA on other genes.
