Identification and Characterization of Spontaneous Auxotrophic Mutants in Fusarium langsethiae.

Analysis of 49 strains of originating from northern Europe (Russia, Finland, Sweden, UK, Norway, and Latvia) revealed the presence of spontaneous auxotrophic mutants that reflect natural intraspecific diversity. Our investigations detected that 49.0% of strains were auxotrophic mutants for biotin, and 8.
