Epichloae endophytes of family Clavicipitaceae (comprising genera Epichloë and Neotyphodium) are fungal symbionts of Pooideae grasses. The associations formed, range from mutually beneficial to antagonistic and the nature of this relationship is dependent upon the importance of vertical (via host seeds) versus horizontal (ascospore mediated) transmission of the fungus. These endophytes can enhance...
Blue mussels (Mytilus edulis) collected from Flødevigen Bay, Norway, in 2001 and 2002 were analysed for yessotoxins (YTXs) by ELISA and yessotoxin (YTX), 45-hydroxyYTX, and carboxyYTX by LC-MS. Results from the two methods were compared to evaluate the ELISA. The response in the ELISA was 3–13 times higher than LC-MS, probably due to the antibodies binding to other YTX analogues not included in the...
The Protoceratium reticulatum cell density at Flødevigen reached a maximum of 2200cells/L on 16 May 2001. The levels of yessotoxins (YTXs) in blue mussels (Mytilus edulis) at the same site increased sharply by 14 May and peaked on 28 May, after which they steadily declined. No other algal species present showed a similar pattern of correspondence. Together with the recent finding that Norwegian strains...
The 1,3-enone isomer (1) of heptanor-41-oxoyessotoxin (2) was isolated from extracts of Protoceratium reticulatum during large-scale production of yessotoxin (4). We found that 2 readily isomerizes to 1 in the presence of dilute ammonia and present evidence for the existence of 40-epi-2 (3) that also isomerizes to 1. 1–3 were detected by LC–MS methods both in extracts of P. reticulatum cultures and...
We have developed a simple and effective method for isolating pectenotoxin-2 (PTX-2) from Dinophysis cells collected from a natural bloom. A two-step extraction procedure followed by two column chromatography steps produced PTX-2 in high purity suitable for use as an analytical standard and for toxicological studies. Incubation of purified PTX-2 with the supernatant from ultracentrifuged blue (Mytilus...
