Mutator MUT-16 and CSR-1 AGO promote expression of chemosensation genes required for dauer formation. Log2 mRNA levels for flp-21, gpa-1, gpa-3, and gpc-1 genes in wild-type, csr-1 hypomorph, and mut-16(pk710) strains, normalized to y45f10d.4, are shown. * P < 0.05 and $ P < 0.005 compared to wild-type, one-way ANOVA with LSD post hoc test. N ≥ 3 biological replicates. Error bars represent propagated SD.
