Chemical ecology of diatom secondary metabolites and their role in shaping planktonic interactions

Diatoms are small eukaryotic plants with over 1600 species, constituting one of the major components of the phytoplankton in freshwater and marine environments. Diatom blooms are believed to initiate and support the cycle of secondary production and growth of fish larvae that depend predominantly on the eggs and larval stages of planktonic copepods, the dominant constituent of the zooplankton in most aquatic habitats. However, evidence has accumulated over the last decade that has progressively challenged the view that diatoms are good and harmless food items for copepod growth and survival. Numerous laboratory studies have shown that when copepods are fed certain diatom diets, the eggs produced either fail to develop to hatching or hatch into malformed nauplii. The compounds responsible for these effects are short-chain polyunsaturated aldehydes (PUAs) that arrest embryonic development in copepods and sea urchins, and have antiproliferative and apoptotic effects on human carcinoma cells. PUAs are cleaved from fatty acid precursors by enzymes activated within seconds after crushing of cells. The production of these compounds can also be accompanied or complemented by the synthesis of other products derived from the enzymatic oxidation of membrane lipids such as hydroxy acids, epoxyalcohols, and ω-oxo acids mainly derived from eicosapentaenoic acid (EPA) and chloroplastic C16-fatty acids. Such compounds are activated chemical defences against grazers, potentially sabotaging future generations of copepods by inducing poor recruitment. This insidious mechanism, which does not deter the herbivore from feeding but impairs its recruitment, will restrain the cohort size of the next generation. Hence, certain diatom diets can negatively impact both copepod egg hatching success (up to 100%) and larval development and survival, with biomass build-up of blooms on the ocean floor that may have significant consequences for ocean ecology and biogeochemistry. Teratogens were unknown for the marine environment until their discovery in diatoms, whereas they are well known for higher terrestrial plants. This property may partially explain why diatoms cause problems in hatcheries where they are still widely used in aquaculture due to their ease of mass cultivation. Although the effects of such toxins are less catastrophic than those inducing poisoning and death, they are none-the-less insidious occurring through abortions, birth defects and reduced larval survivorship. My presentation will focus on some of the newest findings regarding this unique predator-prey relationship and discuss how chemical defence molecules, such as reactive PUAs and other recently described oxylipins from diatoms, can help shape plant-animal interactions and drive bloom dynamics in the plankton.
