Fig. 1From: Expansion of sweet taste receptor genes in grass carp (Ctenopharyngodon idellus) coincided with vegetarian adaptationThe gene structures of T1R2 genes in grass carp (a) and zebrafish (b). The black lines indicate introns, and the black boxes indicate exons. The six gcT1R2 genes we obtained contained 6 exons and 5 introns as well as the genomic structure of two zebrafish T1R2 genesBack to article page
