Approved Strains of Fusarium species

Recently molecular-phylogenetic studies on the species of the genus Fusarium and its allies based on comparative analyses of DNA sequences were much progressed. Many species within the genus were found to be species-complexes containing plural cryptic (hidden) species within their specific circumscription. Division of these species or their redefinition is also in progress. The NARO Genebank has been performing DNA sequence analyses such as Histone H3 gene region, mitochondrion small-subunit ribosomal DNA (mtSSU rDNA), ribosomal DNA (rDNA) ITS regions (including partial sequences of 18S rDNA, ITS1, 5.8S rDNA, ITS2, partial sequences of 28S rDNA), as well as examining their cultural phenotypic characters. It was for the purpose to establish a set of typical Japanese strains of Fusarium species based on the current taxonomic basis. Typical strains which represent individual species were selected as “the Approved Strains for Distribution” of Fusarium species.
