Effects of loss of PLCγ and PLCβ function on pBoc rhythmicity in gon-2;gtl-1 double mutant worms. (A and B) pBoc cycles in individual gon-2;gtl-1 mutant worms fed bacteria producing dsRNA homologous to either PLCγ (A) or PLCβ (B). Different colors and symbols represent different animals. (C) Number of pBocs measured in 12 gon-2;gtl-1;PLCβ(RNAi) worms over 20-min observation period.
