SDE15-transgenic citrus plants are more susceptible to HLB and canker. A, The Las titers in the SDE15-transgenic citrus and EV-transgenic control citrus were determined by TaqMan qPCR at 0, 1, 2, 3, and 4 months post inoculation (mpi) with Las. Each Ct value was represented by means ± se (nSDE15 = 7, nEV = 5). Asterisks represent significant differences in the Las titer between SDE15-transgenic citrus and EV-transgenic control by one-way ANOVA with post hoc test (**P < 0.01). B, Leaf images taken at 3 mpi with Las via budding grafting. C, Canker symptoms were more severe on the SDE15-transgenic citrus than the wild-type citrus at 5 d post inoculation (dpi) with XccA 306. D, Bacterial growth analyses of XccA 306 in the SDE15-transgenic and wild-type Duncan grapefruit. Bacterial cells were infiltrated into citrus leaves at a concentration of 106 CFU mL−1. Error bars indicate se (n = 4). Asterisks represent significant differences in the bacterial population between the SDE15-transgenic citrus and nontransgenic control by one-way ANOVA with post hoc test (**P < 0.01 and ***P < 0.001).
