General Information

General Information Comment Organism
malfunction a mutant lacking ppk is more than 10fold less competitive against wild type Pf0-1 in sterile loam soil low in inorganic phosphate, while a ppk and nonpredicted antisense RNA mutant of Pf0-1 does not have increased sensitivity to osmotic, oxidative, and acid stress, it is more sensitive to elevated temperatures in laboratory medium and during growth in sterile soil Pseudomonas fluorescens
physiological function polyphosphate kinase is necessary for optimal competitive fitness in LB broth culture and sterile loam soil Pseudomonas fluorescens
