TL;DR: This work assembled 89 scaffolds to generate 34 Mbp of nearly contiguous T. reesei genome sequence comprising 9,129 predicted gene models, providing a roadmap for constructing enhanced T.Reesei strains for industrial applications such as biofuel production.

TL;DR: A better understanding of mycoparasitism is offered, and the development of improved biocontrol strains for efficient and environmentally friendly protection of plants is enforced.
Journal ArticleDOI
Complete genome sequence of DSM 30083(T), the type strain (U5/41(T)) of Escherichia coli, and a proposal for delineating subspecies in microbial taxonomy.

TL;DR: Analyses of the genome sequences of a large number of E. coli strains and of strains from > 100 other bacterial genera indicate a value of 79-80% dDDH as the most promising threshold for delineating subspecies, which in turn suggests the presence of five subspecies withinE.
Journal ArticleDOI
Comparative genomics reveals mechanism for short-term and long-term clonal transitions in pandemic Vibrio cholerae.

TL;DR: Based on the comparative genomics, it is concluded that V. cholerae undergoes extensive genetic recombination via lateral gene transfer, and, therefore, genome assortment, not serogroup, should be used to define pathogenic V.cholerae clones.
Journal ArticleDOI

TL;DR: Comparison of the genomes of two members of the B. cereus group revealed differences in terms of virulence, metabolic competence, structural components, and regulatory mechanisms, as well as shared and unique genes among these isolates in comparison to the genome of pathogenic strains B. anthracis Ames and B. cerealus.
