[Metabolic adaptation to a fatty diet: growth and morphogenesis of Artemia salina (L)].

Dietary AMP deficiency induces the morphogenesis of supernumerary gonopodes on abdominal segements. The AMP concentration threshold inducing supernumerary gonopodes depends on the lecithin and albumin concentration of the diet. The AMP concentration threshold corresponding to maximal xanthine oxidase activity depends to the maximal rate of protein biosynthesis. The results suggest the existence of a relation between the developmental physiology of Artemia and AMP and lipid metabolisms, relation which would imply the activity of xanthine oxidase.
