Bacterial QS expands the Xanthomonas campestris pv. campestris invasion of host tissue to trigger host-chlorophagy and maximize disease symptom

Using QS-responsive whole-cell bioreporters of Xcc and cabbage (Brassica
oleracea) as a model system and confocal microscopy, we show a detailed
chronology of QS-facilitated Xcc colonization in the host mesophyll
region. We report the QS-enabled bacterial localization of parenchymal
chloroplast within heterogeneously invaded host mesophyll tissue, leading
triggered leaf-chlorosis and systemic infection.
