Gene discovery, annotation and orthology in the Asian citrus psyllid genome

The citrus industry is currently in a state of emergency due to the uncontrollable spread of Huanglongbing (citrus greening disease). The bacterium associated with this disease is Candidatus Liberibacter asiaticus (CLas), and it is transferred to the phloem of citrus trees by its insect vector, the Asian citrus psyllid (Diaphorina citri).

Since not much is known about the genetics and genomics of the psyllid, a multi- pronged approach was used to analyze the psyllid genome to identify genes that could be involved in pathogen transmission and psyllid survival. The approach will also improve genome assembly and gene identification.
