Cumulative concentration of SA and its metabolites among different scenarios of a vector-host-pathogen interaction in citrus. Data represent the cumulative mean concentration of each molecule ± standard deviation (SD) of six biological replicates per treatment. Statistical analysis was performed with ANOVA with Tukey post-hoc tests. Different letters indicate significant differences between the samples (P < 0.05). White bars represent citrus plants exposed to uninfected psyllids, and black bars denote plants challenged with CaLas-infected psyllids. Abbreviations: OI = One-time inoculation, PI = Pulsed inoculation, and CI = continuous inoculation
