Infection model for sensor performance. a Halo blight symptoms in infected “cacahuate” bean plants with Pseudomonas savastanoi pv. phaseolicola PSFR-01 (Pp) under greenhouse conditions. b, c HR response in tobacco leaves before and after infiltration with i sterile solution of 10 mM MgCl₂, ii Pseudomonas sp. isolated from leaf blight in bean plants in the field (Plb), iii P. savastanoi pv. phaseolicola PSFR-01 re-isolated from experimentally infected bean (Ppb), and iv P. savastanoi pv. phaseolicola PSFR-01 reference strain. d Bean plant showing symptoms of leaf blight, the isolated Pseudomonas sp. was used for testing the sensor. e Colony morphology of three tested Pseudomonas, lower pictures were taken under UV light to show fluorescence
