    We use cell biological approaches to study effector delivery effector and target protein localisations and co-localisations in infected and uninfected plants and to assay effector-target interactions in situ. The latter adds to the protein-protein interaction data obtained with other techniques.

    That s not to say that an effector always modifies plant behaviour. Sometimes an effector might need the plant to be in a particular state to be able to act. Sometimes the effector might need to act together with some other molecule (perhaps another effector) to have an effect. Sometimes the plant may be able to block the effector s action.
