The disease is caused by <i>Candidatus</i> Liberibacter spp., which is vectored by the psyllids <i>Diaphorina citri</i> Kuwayama and <i>Trioza erytreae</i>. Secretory proteins are important in bacterial pathogenesis and structure components. Some of them are expressed at a high level. To obtain the highly-expressed secretory protein genes (SPGs) for antiserum preparation, six candidate SPGs were chosen from <i>Candidatus
