Production of volatile sesquiterpenes by Fusarium sambucinum strains with different abilities to synthesize trichothecenes

Article Abstract:

The sesquiterpene synthesis pathway in Fusarium sambucinum yields six volatile sesquiterpenes including beta-farnesene, beta-chamigrene, beta-bisabolene, alpha-farnesene, trichodiene, and an unknown. The volatile fraction is 82% in the predominant sesquiterpene compounds produced by the fungus grown on wheat kernels. The pattern of volatile sesquiterpenes produced by a species depends on the toxigenicity of the strain.

Genetic diversity of Fusarium oxysporum strains from common bean fields in Spain

Article Abstract:

A study of the genetic diversity of Fusarium oxysporum on bean fields in Spain shows that the fungus reproduces asexually most, if not all, of the time. The strains isolated had the same IGS haplotype and similar karyotype patterns, but were different from Fusarium oxysporum species in the Americas.

Production of a new D-amino acid oxidase from the fungus Fusarium oxysporum

Article Abstract:

A new D-amino acid oxidase has been discovered in Fusarium oxysporum. These enzymes are produced by many organisms, but many do not have qualities that make them appropriate for commercial use in the biotechnology industry.
