Figure 9. Post-embryonic stage expression patterns of
smp-1 and
smp-2 visualized by gfp transcriptional reporters.
smp-1::gfp expression was observed in all four quadrants of body wall muscle, all four enteric muscles, all sex-specific muscles of hermaphrodite and male, in distal tip cells throughout their migration and in cells of the head tentatively identified as sensory neuron support cells (not shown). We also observed
smp-1::gfp expression in epidermal cells hyp 4, in the head (A, arrowhead), and hyp 10, in the tail whip (B, arrowhead), gonadal sheath cell, sperm and excretory system (data not shown). (D) We have also tentatively identified inner labial neurons (data not shown) and the AVL neuron cell body (arrowhead) and axon (arrow), which is located in the nerve ring and sends its axon along the ventral nerve cord into the tail. (C)
smp-2::gfp expression was observed in a mononuclear pharyngeal cell (
m6) (open arrow), in tentatively identified URAV/D motorneurons and inner labial neurons, in intestinal cells and in the sphincter muscle (data not shown).
smp-2::gfp is also expressed in the body wall and head muscle quadrants (C, white arrow and white arrowhead, respectively).
