FOXI1 and infection: In order to test for the specificity of this effect, four of the strongest RNAi hits from the N. parisii screen were tested for their effect on larval development after infection with P. aeruginosa. We found that RNAi of some genes, like unc-55 and fkh-10, also inhibited arrest on P. aeruginosa, suggesting they are important for a general larval arrest response, or slowing of development upon infection (Fig 1D) [29, 30].
