Fig. 7. Defects in the migration of the QR neuroblast and its descendants in the
src-1(cj293) mutant. (A) Schematic representation of the AVM and ALM
neuronal cells that originate from the QR neuroblast and the PVM descendant of
the QL neuroblast. (B-E) The GFP signals produced from mec-7::gfp in
wild-type worms (B) and the src-1(cj293) mutant (D) were visualized
by epifluorescence. The merged GFP and DIC images are shown in C and E. Scale
bar: 20 µm. (F) The genetic interaction of the aberrant AVM phenotype in
the src-1(cj293) mutant with the ced-5/-12 mutations. The
final positions of AVM and PVM in the wild-type and indicated mutant worms
were scored according to their relative distance from the stationary Vn.a and
Vn.p cells shown on the x-axis.
