Molecular Variation and Phylogeny within Fusarium avenaceum and Related Species

Many recent articles feature research on the Fusarium tricinctum species complex (FTSC), and their authors present different ideas how isolates of this can be identified at level. In previous studies, our aim was to investigate phylogeny FTSC strains, which researchers have morphologically as avenaceum, arthrosporioides, anguioides. current study, phylogenetic maximum parsimony likelihood analyses DNA sequences translation elongation factor 1-alpha (TEF1) combined TEF1 beta-tubulin (TUB2) supported existence least four main groups among these strains. Main Group I mainly contains F. avenaceum while II two subgroups, one primarily includes arthrosporioides other European anguioides III strains from plants that originated Asia, including are mostly isolated trees, form IV. A fifth group (Main V) only by sequences. The previously found us based TUB2 could connected new FTSC, were addition, we significantly differ Groups I-V, grouped some them single, intermediate, or sister groups. All work, single intermediate may represent subgroups constitute intraspecific variation. Regardless whether they belonged groups, all analysed able enniatins 2-amino-14,16-dimethyloctadecan-3-ol, but did not produce beauvericin.
