Fig. 2From: Real-time monitoring of Ralstonia solanacearum infection progress in tomato and Arabidopsis using bioluminescence imaging technologyThe light intensity of Ralstonia solanacearum FJ91-LUX is linearly correlated to its concentration. a Regression analysis of bioluminescent signals versus bacterial concentrations. The bioluminescent signals of the bacteria at the indicated concentrations were measured. Data are shown as the mean ± SD (n = 3). b Bioluminescent signals of bacteria after successive subculturing. Data are shown as the mean ± SD (n = 3). c Light intensity of FJ91-LUX after continuous growth on solid media. Data are shown as the mean ± SD (n = 4)Back to article page
