An
unc-129::gfp reporter was introduced in
ten-1(
ok641) mutant animals. This reporter in expressed in the DA/DB neurons that project circumferentially from the ventral cord to innervate the dorsal body muscles, and also weakly in the dorsal muscle cells. Consistent with the lack of any obvious Unc phenotype, no defects were observed in the DA/DB neurons of
ten-1(
ok641) mutants. Unexpectedly however, a 20-fold increase in the expression levels of the reporter was observed in the dorsal muscle cells of mutants, as judged by the intensity of the GFP signal.
