In wild-type germlines, the antisense, but not the sense, probe detected RNAs broadly distributed in the distal germline. To examine
fbf-1 mRNA specifically, dissected
fbf-2(
q738) germlines were hybridized and found staining with the antisense probe throughout the distal arm. To examine
fbf-2 mRNA specifically, dissected
fbf-1(
ok91) germlines were hybridized and found staining with the antisense probe that was most abundant in the distal end.
