Fig. 1From: Retention of fatty acyl desaturase 1 (fads1) in Elopomorpha and Cyclostomata provides novel insights into the evolution of long-chain polyunsaturated fatty acid biosynthesis in vertebratesMaximum likelihood phylogenetic analysis of FADS1 and FADS2 amino acid sequences. Values at nodes indicate posterior probabilities, * indicates FADS isolated and functionally analysed in this work. Black arrow (3R WGD) approximates the timing of the teleost duplication.
