The spatial expression pattern of Ss-riok-1 in the post-free-living first-stage and second-stage larvae.DIC (A, C) and fluorescence (B, D) images of transgenic S. stercoralis post-free-living L1-L2 stage larvae expressing Ss-riok-1p::gfp::Ss-era-1t. (A, B) GFP expression in the pharynx (P), head neurons (HN), body neurons (BN) and tail phasmidial neurons (ph) and longitudinal nerve tracts (L), GFP expression is also observed in the neurons (R) with positional homology to neurons of C. elegans in retrovesicular ganglion (RVG). (C, D) GFP expression in the commissures between body neurons and longitudinal nerve tracts (arrow). Scale bars = 100 µm.
