One factor that may play a role in their ecological success is the production of complex secondary metabolite compounds that can have anti-predator, allelopathic, or other toxic effects on marine organisms, and also cause seafood poisoning in humans. Our knowledge about the genes involved in toxin biosynthesis in dinoflagellates is currently limited due to the complex genomic features of these organisms. Most recently, the sequencing of dinoflagellate transcriptomes has provided us with valuable insights into the biosynthesis of polyketide and alkaloid-based toxin molecules in dinoflagellate species. This review synthesizes the recent progress that has been made in understanding the evolution, biosynthetic pathways, and gene regulation in dinoflagellates with the aid of transcriptomic and other molecular genetic tools, and provides a pathway for future studies of dinoflagellates in this exciting omics era. Keywords: dinoflagellates; toxins; transcriptomics; polyketides; alkaloids 1. Introduction Marine microbial eukaryotes are a diverse group of organisms comprising lineages that differ widely in their evolutionary histories, ecological niches, growth requirements, and nutritional strategies [1–5].

  • Influence of Environmental Parameters on Karenia Selliformis Toxin Content in Culture

Route de l'aéroport, km 1, 3003 Sfax, Tunisie Abstract: Karenia selliformis strain GM94GAB was isolated in 1994 from the north of Sfax, Gabès gulf, Tunisia. This species, which produces gymnodimine (GYM) a cyclic imine, has since been responsible for chronic contamination of Tunisian clams. A study was made by culturing the microalgae on enriched Guillard f/2 medium. The influence of growing conditions on toxin content was studied, examining the effects of (i) different culture volumes (0.25 to 40 litre flasks), (ii) two temperature ranges (17-15°C et 20-21°C) and (iii) two salinities (36 and 44). Chemical analyses were made by mass spectrometry coupled with liquid chromatography (LC-MS/MS). Results showed that (i) the highest growth rate (0.34 ± 0.14 div d-1) was obtained at 20°C and a salinity of 36, (ii) GYM content expressed as pg eq GYM cell-1 increased with culture time. The neurotoxicity of K. selliformis extracts was confirmed by mouse bioassay. This study allowed us to cal- culate the minimal lethal dose (MLD) of gymnodimine (GYM) that kills a mouse, as a function of the number of K.

It is prevalent in tropical regions worldwide, including in Australia. Ciguatoxins are produced by some species of Gambierdiscus. Therefore, screening of Gambierdiscus species identification through quantitative PCR (qPCR), along with the determination of species toxicity, can be useful in monitoring potential ciguatera risk in these regions. In Australia, the identity, distribution and abundance of ciguatoxin producing Gambierdiscus spp. is largely unknown. In this study we developed a rapid qPCR assay to quantify the presence and abundance of Gambierdiscus lapillus, a likely ciguatoxic species. We assessed the specificity and efficiency of the qPCR assay. The assay was tested on 25 environmental samples from the Heron Island reef in the southern Great Barrier Reef, a ciguatera endemic region, in triplicate to determine the presence and patchiness of these species across samples from Chnoospora sp., Padina sp.
