2.7.4.1 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
