Three-day egg production on mixed-diets containing toxic or nontoxic food.

<p>Each diet consisted of 500μgC L^-1 of the standard diet (equal carbon of <i>Tetraselmis sp</i>. and <i>Thalassiosira weissfloggi</i>) mixed with 200 μgC L^-1 of either toxic <i>Alexandrium fundyense</i> or non-toxic <i>Alexandrium tamarense</i>. The data are plotted as A) within toxic and non-toxic treatments among expression groups (n = 164), and B) within expression groups between food treatments (n = 165). Abbreviations- Wild-type: Predominantly wild-type isoform expression (PWI); ~1:1: approximately equal isoform expression (EI); Mutant: predominantly mutant isoform expression (PMI). Symbol in B represents statistical differences between EPR on toxic and non-toxic food for the PMI expression group (student’s t-test, <i>p</i><0.05). Conversion to <i>f</i>moles cell^-1 can be made by multiplying pgSTX equivalents by a conversion factor of 2.54.
