Pleiotropic effects of gaca on pseudomonas fluorescens pf0-1 in vitro and in soil

Abstract

Pseudomonas species can exhibit phenotypic variation resulting from gacS or gacA mutation. P. fluorescens Pf0-1 is a gacA mutant and exhibits pleiotropic changes following the introduction of a functional allele. GacA enhances biofilm development while reducing dissemination in soil, suggesting that alternative Gac phenotypes enable Pseudomonas sp. to exploit varied environments. © 2013, American Society for Microbiology.
