Resistance to Cry21A was compared among wild type N2, egl-9(sa307), egl-9(sa307) transformed with cpr-1::gfp, and egl-9(sa307) animals transformed with cpr1::egl-9. Two representative worms are shown for each strain 48 h after feeding on E. coli-expressed Cry21A. Wild-type animals and egl-9(sa307) animals transformed with cpr1::egl-9 are similarly sensitive to Cry21A whereas egl-9(sa307) animals and egl-9(sa307) animals transformed with cpr-1::gfp are relatively resistant.
