摘要: Diatom oxylipins have been observed to deleteriously impact copepod reproductive success. However, field studies revealed very variable and case-dependent results. Therefore, the plasticity of diatom oxylipin metabolism was studied among four clones marine Skeletonema marinoi Sarno et Zingone. by two lipoxygenase (LOX) activity assays carried out at different pH values quantification. The showed no major metabolic differences in terms protein content or growth rate. produced significantly higher levels than other two. LOX measurements also indicated clonal variability fatty acid oxidative metabolism. presence clone-specific may play a role shaping population dynamics conferring selective advantages certain clones.
