Early Responses During Plant-Bacteria Interactions in Tobacco Cell Suspensions

Abstract

Bacteria that induce a hypersensitive response in tobacco leaves initiate a net uptake of extracellular H + and a net increase in extracellular K + in tobacco suspension cells. Other studies have shown that these interactions also result in a transient increase in lipid peroxidation and O 2 - production. The relationships between these early plant responses were studied simultaneously using suspension-cultured tobacco cells and compatible, incompatible, and saprophytic bacteria (...)
