“…haematococca MPIII and phylogenetic species FSSC 17. Members of this clade are known to induce stem blight on mulberry (Morus alba) trees (Sawada 1959, Sakurai & Matuo 1959, Matuo & Snyder 1973. Additional sequences from South Korea (M. alba, JS-169), were also included in this study, originating from the whole genome sequence of a non-pathogenic endophytic strain published in Kim et al (2017 ; Table 1).…”

The genus Neocosmospora (Fusarium solani species complex) contains saprobes, plant endophytes and pathogens of major economic significance as well as opportunistic animal pathogens. Advances in biological and phylogenetic species recognition revealed a rich species diversity which has largely remained understudied. Most of the currently recognised species lack formal descriptions and Latin names, while the taxonomic utility of old names is hampered by the lack of nomenclatural type specimens. Therefore, to stabilise the taxonomy and nomenclature of these important taxa, we examined type specimens and representative cultures of several old names by means of morphology and phylogenetic analyses based on rDNA (ITS and LSU), rpb2 and tef1 sequences. Sixty-eight species are accepted in Neocosmospora, 29 of them described herein as new; while 13 new combinations are made. Eleven additional phylogenetic species are recognized, but remain as yet undescribed. Lectotypes are proposed for eight species, seven species are epitypified and two species are neotypified. Notes on an additional 17 doubtful or excluded taxa are provided.

“…Snyder and Hansen [ 6 ] represented FSSC as a complex species in the Martiella section [ 1 , 7 , 8 ]. Seven mating populations (MPI–VII) were determined for F. solani [ 9 – 12 ]. Members of FSSC mating populations MPI, MPV, and MPVI were placed in distinct groups by phylogenetic analysis [ 13 ].…”

Morphological and Phylogenetic Analysis of Fusarium solani Species Complex in Malaysia

Members of Fusarium solani species complex (FSSC) have been known as plant, animal, and human pathogens. Nevertheless, the taxonomic status of such an important group of fungi is still very confusing and many new species as well as lineages have been elucidated recently. Unfortunately, most of the new taxa came from temperate and subtropical regions. Therefore, the objectives of the present study were to identify strains of FSSC recovered from different sources in Malaysia. In the present study, 55 strains belonging to the FSSC were examined and phylogenetically analyzed on the basis of internal transcribed spacer (ITS) regions and partial translation elongation factor-1 (TEF-1α) sequences. Based on morphological features, a total of 55 strains were selected for molecular studies. Based on morphological features, the strains were classified into four described Fusarium species, namely Fusarium keratoplasticum, Fusarium falciforme, FSSC 5, and Fusarium cf. ensiforme, and one unknown phylogenetic species was introduced. Although the data obtained from morphological and molecular studies sufficiently supported each other, the phylogenetic trees based on ITS and TEF-1α dataset clearly distinguished closely related species and distinctly separated all morphological taxa. All members of FSSC in this research were reported for the first time for Malaysian mycoflora.

Electrophoretic karyotyping and gene mapping of seven formae speciales in Fusarium solani

et al. 2002

Chromosomal DNAs of 22 strains in 7 formae speciales (f. spp.) of Fusarium solani were compared by pulsed field gel electrophoresis (PFGE) and gene mapping on the chromosomes. Using PFGE, complete separation of the full components of the genome was not attained, due to the limited resolution of large chromosomes, but 5-12 chromosomes with sizes of 0.6-5.7 Mbp were resolvable for every strain. Although each strain had a unique banding profile, similarity in the banding profile was noticed among strains of the same (f. sp.). In gene mapping, the ribosomal RNA gene (rDNA) and putative pathogenesis-related genes encoding kievitone hydratase (khs), pisatin demethylase (pda) and pectate-degrading enzyme (pelA) were located on the chromosomes separated by PFGE. rDNA was always detected on the stacked large bands of 5.2-5.7 Mbp. The khs gene was detected on a chromosome of 2.8-5.4 Mbp in all f. sp. phaseoli strains and one strain of f. sp. pisi. The pda gene was detected on a chromosome of 1.4-5.6 Mbp in f. sp. pisi and pelA was localized on a chromosome of 2.3-2.9 Mbp in f. spp. pisi, xanthoxyli, batatas and mori. The results of PFGE and Southern blot hybridization supported the idea that each f. sp. of F. solani (or mating population of the teleomorph Nectria haematococca) has a distinctive genomic organization, as previously inferred from molecular phylogenetic analyses.
