The psyllid has approximately 20,000 potential genes — an impossible number to complete — but the group will annotate as many as possible.

They are gearing up to publish their first «release» of the official gene set as a collaborative paper, which will be a vital resource in finding a way to stop the psyllid from spreading the citrus greening pathogen.

But before they can figure out a way to disrupt the insect's transmission of the bacterium, they need a starting point, namely, a list of potential genes to target on the psyllid genome.

The bacteria that causes HLB is carried by the Asian citrus psyllid, a tiny insect that feeds on leaves and stems of infected citrus trees, then carries the bacteria to healthy trees.

These symptoms are associated with a bacterium called «Candidatus Liberibacter asiaticus,» referred to as CLas for short, which is spread from tree to tree by its tiny insect vector, the Asian citrus psyllid (Diaphorina citri).

Published in Infection and Immunity, they present a possible mechanism for how CLas can infect its psyllid vector.

Although this link remains to be tested directly, understanding its mechanism could yield an important target for disrupting the psyllid - CLas interaction.
