Citrus Huanglongbing, one of the most devastating citrus diseases, is caused by ‘ Candidatus Liberibacter asiaticus’ ( CLas). Polyamines are aliphatic nitrogen-containing compounds that play important roles in disease resistance and are synthesized primarily by two pathways: an arginine decarboxylation pathway and an ornithine decarboxylation pathway. However, it is unclear whether polyamines play a role in the tolerance of citrus to infection by CLas and, if so, whether one or both of the core
