Association Analysis between Genetic Variants of and and Poly-Unsaturated Fatty Acids in Common Carp ().

The allo-tetraploid common carp, one widely cultured food fish, is able to produce poly-unsaturated fatty acids (PUFAs). The genetic markers on the PUFA contents for breeding was limited. The polymorphisms in and , the rate-limiting enzymes in the PUFA biosynthesis, have not been investigated yet.

Association between the Polymorphisms of and and Poly-Unsaturated Fatty Acids in Common Carp ().

Fatty acid desaturase 2 () is one of the rate-limiting enzymes in PUFAs biosynthesis. Compared with the diploid fish encoding one , the allo-tetraploid common carp, one most important food fish, encodes two fads2 genes ( and ). The associations between the contents of different PUFAs and the polymorphisms of and have not been studied.
