Molecular nature of spontaneous modifications in gacS which cause colony phase variation in Pseudomonas sp. strain PCL1171.

Journal of bacteriology - 1 Jan 2005

van den Broek Daan, Chin-A-Woeng Thomas F C, Bloemberg Guido V, Lugtenberg Ben J J

Abstract excerpt

Pseudomonas sp. strain PCL1171 displays colony phase variation between opaque phase I and translucent phase II colonies, thereby regulating the production of secondary metabolites and exoenzymes. Complementation and sequence analysis of 26 phase II mutants and of 13 wild-type phase II sectors growing out of phase I colonies showed that in all these cases the phase II phenotype is caused by spontaneous mutations...
