"We found that simultaneous RNAi depletion of the redundantly functioning paralogs
pgl-1 and
pgl-3 (Kawasaki et al., 2004) caused
msp-3 expansion in 20% of worms (supplementary material Fig. S5; Table 1). This expansion was also observed in 18% of worms only fed
pgl-1 RNAi, and in 30% only fed
glh-1 RNAi. We also observed an expanded
msp-3 domain in 18% of
glh-4(
gk224)
glh-1(
ok439) double mutants, in 31% of
pgl-1(
bn101) single mutants and in 20%of
pgl-3(
bn104) single mutants. Proximal germlines in
pgl-1(
bn101);
pgl-3(
bn104) did not show an expansion of the
msp-3 domain, but these double mutants contained very severe germline proliferation defects that might have masked this phenotype."
