Prophages are highly dynamic components in the bacterial genome and play an important role in intraspecies variations. There are at least two prophages in the chromosomes of Candidatus Liberibacter asiaticus' (Las) Floridian isolates. Las is both unculturable and the most prevalent species of Liberibacter pathogens that cause huanglongbing (HLB), a worldwide destructive disease of citrus. In th...

Citrus greening (Huanglongbing, HLB) is one of the most destructive diseases of citrus worldwide. In South Asia HLB has been known for more than a century, while in Americas the disease was found relatively recently. HLB is associated with three species of 'Candidatus Liberibacter' among which 'Ca. Liberibacter asiaticus' (CLas) has most wide distribution. Recently, a number of studies identifi...

Lasiodiplodia theobromae is a fungal pathogen associated with perennial tropical fruit plants worldwide. In citrus, L. causes stem-end rot (Diplodia rot), damaging postharvest disease that aggravated when trees are also infected the citrus greening bacteria ‘Candidatus Liberibacter asiaticus’. Due to latent infection of during preharvest stage, it becomes difficult control by chemical or physic...
