Analysis of the gacS-gacA regulatory genes of spontaneous mutants of Pseudomonas fluorescens biocontrol strain PfG32R



Analysis of the gacS-gacA regulatory genes of spontaneous mutants of Pseudomonas fluorescens biocontrol strain PfG32R



Journal of General Plant Pathology 72(3): 159-167



Pseudomonas fluorescens strain PfG32R, a potential biocontrol agent against soilborne pathogens, frequently loses its antifunloal activity and ability to produce enzymes. To characterize genetically the instability of these bacterial functions, we analyzed gacS and gacA genes of PfG32R and three spontaneous mutants of PfG32R (NR1, NR9, and ASW6), which had lost their ability to produce proteases and antifungal activities.
