Abstract:
1. A method for testing for the presence of a plant pathogen in a plant sample comprising: a) preparing a plant sample for testing for the presence of a plant pathogen; b) adding beads to the plant sample, wherein the beads bind to a plant pathogen; c) adding emitter cells to said beads, the emitter cells comprising receptors which are expressed on the surface of the emitter cells and are specific to the plant pathogen to be detected, wherein binding of the plant pathogen to the receptors result in an increase in calcium concentration in the cytosol of the emitter cell, wherein the emitter cells further comprise an emitter molecule that emits a photon in response to the increase in intracellular calcium; and d) detecting photon emission, wherein photon emission is indicative of a plant pathogen in the sample.
