The present study included two experiments to examine the effect of salinity and diet on the expression of the [DELTA]6 Fadlike gene.
Homology analysis showed that the [DELTA]6 Fadlike protein of Litopenaeus vannamei shared 77%, 73%, 73%, and 70% sequence homology with that of Macrobrachium nipponense, Scylla paramamosain, Portunus trituberculatus and Eriocheir sinensis, respectively (Fig.
In conclusion, this study is the first to report the [DELTA]6 Fadlike gene in Litopenaeus vannamei, involving the investigation of its expression in relation to HUFA biosynthesis under different salinity conditions or from different dietary lipid sources.
