A Co-Cultivation System to Study the Molecular Responses of Plant Hosts and Interacting Bacteria

Source: Nathoo, N., et al. A Hydroponic Co-cultivation System for Simultaneous and Systematic Analysis of Plant/Microbe Molecular Interactions and Signaling. J. Vis. Exp. (2017).This video demonstrates a hydroponic co-cultivation system for studying plant–bacteria interactions under sterile conditions. Plant seedlings are transferred into a sterile, acidic growth medium, incubated, and inspected for contamination before inoculation with Agrobacterium. The activated bacteria attach to plant roots, transfer T-DNA into plant cells, and promote molecular changes that enhance bacterial colonization.
