| Abstract |
If the cuticle acts as a protective barrier against environmental insults, several pathogens have developed strategies that use it as a way to infect C. elegans. The fungus Drechmeria coniospora produces spores that attach to the cuticle, before hyphae invade the body. Mutants with an altered surface coat, the outermost layer of the cuticle, including bus-2, bus-4, bus-12 and bus-17 show increased adhesion of fungal spores (Rouger et al, 2014; Zugasti et al, 2016). We unexpectedly found that D. coniospora spores attach unusually densely around the mouth of unc-119 mutants. Interestingly, this phenotype is not rescued by the C. briggsaeunc-119 construct that is conventionally used to rescue neuronal unc-119 phenotypes.
