Two novel aflatoxin-producing species from Argentinean peanuts, Page 1 of 1

| /docserver/preview/fulltext/ijsem/58/3/725-1.gif

  • Two novel species from section from different species of (peanuts) in Argentina are described as sp. nov. and sp. nov. Their novel taxonomic status was determined using a polyphasic taxonomic approach with phenotypic (morphology and extrolite profiles) and molecular (-tubulin and calmodulin gene sequences) characters. resembles and in producing aflatoxins B and B, cyclopiazonic acid, kojic acid and aspergillic acid, but in addition it produces aflatoxins G and G, aflavarins, aflatrem, aflavinines, parasiticolides and paspaline. This species also includes several isolates previously assigned to group II and three Australian soil isolates. produces aflatoxins B, B, G and G, kojic acid, chrysogine and parasiticolide, and some strains produce aspergillic acid. The type strain of is CBS 117610 =IBT 25020 and that of is CBS 117635 =IBT 27196. The Mycobank accession numbers for sp. nov. and sp. nov. are respectively MB 505188 and MB 505189 (http://www.mycobank.org).

  • The GenBank/EMBL/DDBJ accession numbers for the -tubulin and calmodulin gene sequences of the strains examined in this study are shown in Fig. 1 F1 and Supplementary Fig. S1.

  • A neighbour-joining phylogenetic tree based on calmodulin gene sequences and colour versions of Figs 2 F2 and 3 F3 are available as supplementary material with the online version of this paper.
