WebbThe Situation: Citrus huanglongbing (HLB), previously called citrus greening disease, is one of the most destructive diseases of citrus worldwide. Originally thought to be caused by a virus, it is now known to be caused by unculturable phloem-limited bacteria. There are three forms of greening that have been described. WebbThe phloem-limited bacteria are adapted to the unique phloem environment as they lack many genes necessary for core metabolic processes; however; this property makes them unculturable in an artificial medium [ 29 ].
