Role of RpoS in stress tolerance and environmental fitness of the phyllosphere bacterium Pseudomonas fluorescens strain 122.

Phytopathology - 1 Jun 2009

Stockwell Virginia O, Hockett Kevin, Loper Joyce E

Abstract excerpt

Bacteria living epiphytically on aerial plant surfaces encounter severe and rapidly fluctuating environmental conditions, and their capacity to withstand environmental stress contributes to epiphytic fitness. The stationary phase sigma factor RpoS is a key determinant in stress response of gram-negative bacteria, including Pseudomonas spp. This study focused on the role of RpoS in stress response and epiphytic...
