NID-1 localization in
cg118 and cg119 mutant animals.
Animals were stained with anti–NID-1 antiserum (A, C, E, G, H, and I)
or anti-myosin A (B, D, F, and J). (A and B) Twofold stage
cg118 mutant embryo shows NID-1 localization under body
wall muscle (arrowheads) and on the surfaces of the pharynx (p),
intestine (i), and gonad (g). (C and D) Threefold stage
cg118 mutant embryo showing NID-1 accumulation at the
basal surfaces (arrowheads) and edges (arrows) of body wall muscle
quadrants and on the surfaces of the pharynx (p) and intestine (i). (E
and F) Twofold stage cg119 mutant embryo showing
complete lack of staining by anti–NID-1 antibodies. (G) L1 stage
cg118 mutant larva showing NID-1 accumulation at nerve
ring (nr), under body wall muscle (arrow), and on the surfaces of the
pharynx (p), intestine (i), and gonad (g). (H) Late L4 stage
cg118 mutant larva showing NID-1 accumulation on the
developing spermatheca (st), uterus (u), and vulva (vu), and at the
distal tip cell (dt). Weaker accumulation on the surface of the gonad
is also seen (arrow). (I and J) Ventral view of cg118
mutant adult hermaphrodite showing NID-1 accumulation at the ventral
edges of the ventral body wall muscle quadrants (arrows) and at the
edges between adjacent muscle cells (arrowheads).
