Free amino acid profiles of permissive hosts (P) of <i>Candidatus</i> Liberibacter asiaticus (<i>C</i>Las) and non-permissive (NP) plants.

<p>Permissive hosts comprise phloem sap of young and mature flush shoots of three citrus species, periwinkle plants and whole <i>Diaphorina citri</i> nymphs and adults, while non-permissive host comprise young and mature shoots of curry leaf, orange jasmine and white sapote. Results are based on mean values obtained for growth stages of each plant species (three replicates) and are shown as the ratios of accumulation between the two host categories. Asterisk indicates significant differences according to t-test (P<0.05).
