Citrus fruit pathogen genome sequenced

"Citrus greening" (also known as Huanglongbing, HLB, or yellow dragon disease) is a tree disease, caused by the bacteria Candidatus Liberibacter asiaticus and Candidatus Liberibacter africanus. The bacterium is transmitted by psyllid insects.

Ca. Liberibacter asiaticus' genetic sequence has been saved to GenBank, an open access database sponsored by the National Center for Biotechnology Information (NCBI), a division of the National Library of Medicine (NLM) at the National Institutes of Health (NIH).
