Classic fungal natural products in the genomic age: the molecular legacy of Harold Raistrick.
Covering: 1893 to 2017Harold Raistrick was involved in the discovery of many of the most important classes of fungal metabolites during the 20th century. This review focusses on how these discoveries led to developments in isotopic labelling, biomimetic chemistry and the discovery, analysis and exploitation of biosynthetic gene clusters for major classes of fungal metabolites including: alternariol; geodin and metabolites of the emodin pathway; maleidrides; citrinin and the azaphilones; dehydrocurvularin; mycophenolic acid; and the tropolones. Key recent advances in the molecular understanding of these important pathways, including the discovery of biosynthetic gene clusters, the investigation of the molecular and chemical aspects of key biosynthetic steps, and the reengineering of key components of the pathways are reviewed and compared. Finally, discussion of key relationships between metabolites and pathways and the most important recent advances and opportunities for future research directions are given.

Arginine acts as an inhibitor of the biosynthesis of several mycotoxins.
It is well known that the type and the availability of nitrogen have a great influence on the biosynthesis of certain mycotoxins. Here it is shown that some amino acids have no influence, some others strongly support and a third group inhibits the biosynthesis of ochratoxin (OTA) by Penicillium nordicum even in a complex medium, such as PDA. Arginine (Arg) is one of the strong OTA inhibiting amino acids. It was shown that Arg not only inhibits OTA in Penicillium but also citrinin (CIT) biosynthesis in Penicillium verrucosum, Penicillium expansum and Penicillium citrinum and alternariol (AOH), alternariol monomethylether (AME) and tenuazonic acid (TeA) biosynthesis in Alternaria alternata. The minimal inhibitory concentration of Arg differs depending on the mycotoxin and the species analysed. However, the OTA biosynthesis by P. verrucosum and P. nordicum was most sensitive. Growth, on the other hand, was much less affected by Arg. Urea, a metabolite of Arg catabolism, shows a similar inhibitory activity. In wheat medium containing 50mM Arg almost no OTA was produced by Penicillium, in contrast to plain wheat medium.
