Abstract
Research on the biological control of Pythium damping-off with Enterobacter cloacae has provided important insights into how pathogen-associated and plant-associated factors regulate biological control activity.
The behavior of pathogen propagules, their temporal response to germinating seeds, the exudate molecules eliciting such responses, and the mechanisms of biological control by E. cloacae are all key to understanding efficacy of biological control in this system.
Analysis of these factors may explain the success or failure of biological control on different plant species and in other biological control systems.
Details of how specific attributes of this model system relate to broader concepts of biological control will be described.
