Fig. 8From: Expansion of sweet taste receptor genes in grass carp (Ctenopharyngodon idellus) coincided with vegetarian adaptationThe gene expressions of gcT1R2s in the tongue of grass carp transition from carnivory to herbivory. Relative mRNA expression was quantified using real-time PCR and normalized against EF1 as a housekeeping gene. All values represent the mean ± S.E.M. (n = 6). Values marked with different lowercase letters are significantly different (one-way ANOVA, P < 0.05)Back to article page
