    Project Details

    Description

    In recent years several reports have shown that small molecules - homoserine lactone derivatives - are excreted from bacteria and received by neighbouring cells in which they cause induction or repression of specific genes. The major goal of the project is to investigate the impact of these molecules in the plant root environment with respect to the physiological performance of root associated bacteria, the effect on virulence, secondary metabolite production, motility and exoenzyme production, and the activation of pathogenesis traits.
    A first important objective for the DTU group is to construct a specific monitoring system for homoserine lactones based on the green fluorescent protein in order to make detection of these signals compatible with the fluorescence microscopes. The project was terminated by a contracters' meeting in Copenhagen in December 1999.
