Fig. 2. SRA-13 expression pattern. (A) Expression of the sra-13::gfp translational reporter in the two pairs of AWA and AWC chemosensory neurones in the head of an adult animal (arrows). A 3D reconstruction of confocal sections through the head region is shown. (B) Expression of the sra-13::gfp transcriptional reporter in the body wall muscles and hypodermis of an L4 animal and (C) in the vulval muscles that control egg-laying in the adult hermaphrodite. (D) Nomarski image of the animal shown in C. Scale bars: 10 µm in A,D; 50 µm in B.
