Clustering of trichothecene-producing Fusarium strains determined from 28S ribosomal DNA sequences
Article Abstract:
The five prime end of the large nuclear ribosomal DNA (rDNA) of the coding region of Fusarium strains were analyzed to determine the genetic relationship of the trichothecene-producing microbe. Sequence analysis of the DNA at the five prime end of the large nuclear rDNA indicated a correlation between trichothecene production and the phylogenetic placement of a large number of Fusarium species. Furthermore, the correlation between trichothecene production and rDNA sequence indicated the need for a revision of the systematics of the Fusarium strains.

The faeA genes from Asperigillus niger and Aspergillus tubingensis encode ferulic acid esterases involved in degradation of complex cell wall polysaccharides
Article Abstract:
A research was conducted to investigate the characterization and cloning of a gene encoding a ferulic acid esterase, faeA, from Aspergillus niger and Aspergillus tubingensis. The faeA gene was induced by growth on wheat arabinoxylan and sugar beet pectin. Polyclonal antibodies were utilized in the analysis of supernatant samples from Aspergillus cultures. Results indicated a lipaselike serine active site in the gene product when there was spacing within the catalytic trade from lipases.
