ADIPOR2 and Glucose intolerance: (B–D) Introduction of a wild-type fld-1(+) transgene in control N2 worms has no effect on their growth but restores glucose intolerance in the paqr-2(tm3410);fld-1(et49) double mutant, which shows that fld-1(et49) is a loss-of-function mutation that protects paqr-2 mutant worms from glucose toxicity; transgenic worms are positive for the pharyngeal GFP marker.
