    ABSTRACT: Environmental factors can cause changes in the content of the fungal genome during evolution. In this study, a fungus used as a biocontrol agent, Trichoderma virens FT-333 (from a tropical marine climate) has been isolated. The genome (38.6 Mbp; GC content, 49.43%) has a total of 12 751 proteins. Gene ontology (GO) terms (cellular component and molecular function) and KEGG analyses demonstrated the importance of the secretion function in FT-333. Compared to the other Trichoderma species, copy number of genes related to defense and nutrient utilization was variable. © FEMS 2015. All rights reserved.

    ABSTRACT: We report the draft genome sequence from Aeromonas salmonicida sp. strain CBA100, which was characterized as an antibiotic-resistant bacterium isolated from infected rainbow trout. The total size of the genome is 4 788 109 bp, with a G + C content of 60.55%. Comparison of its open reading frames shows that the closest homologue to one third of the genes of strain CBA100 are found in A. hydrophila. The strain contains several efflux pumps and putative genes that confer resistance to multiclass antibiotics, including macrolide, β-lactamics, florfenicol and quinolones. The antibiogram profile suggests that efflux pumps are the main mechanism of resistance to non-β-lactamic antibiotics. This is the first genome of a Chilean isolate of A. salmonicida, which should shed light on the design of strain-specific vaccines against this pathogen and reduce the use of antibiotics for preventive treatment in Chilean aquaculture. © FEMS 2014.

    ABSTRACT: We announce the genome sequence for Xanthomonas species strain Nyagatare, isolated from beans showing unusual disease symptoms in Rwanda. This strain represents the first sequenced genome belonging to an as-yet undescribed Xanthomonas species known as species-level clade 1. It has at least 100 kb of genomic sequence that shows little or no sequence similarity to other xanthomonads, including a unique lipopolysaccharide synthesis gene cluster. At least one genomic region appears to have been acquired from relatives of Agrobacterium or Rhizobium species. The genome encodes homologues of only three known type-three secretion system effectors: AvrBs2, XopF1 and AvrXv4. Availability of the genome sequence will facilitate development of molecular tools for detection and diagnostics for this newly discovered pathogen of beans and facilitate epidemiological investigations of a potential causal link between this pathogen and the disease outbreak. © FEMS 2014.

    ABSTRACT: Among other factors, a distinct gene redundancy is discussed to facilitate high metabolic versatility of rhodococci. Rhodococcus opacus 1CP is a typical member in that respect and degrades a multitude of (chlorinated) aromatic compounds. In contrast to the central pathways of aromatic degradation in strain 1CP little is known about the degree of gene redundancy and to what extent this is reflected on protein level within the steps of peripheral degradation. By means of degenerated primers deduced from tryptic peptides of a purified phenol hydroxylase component and by using the amplified fragment as a labelled probe against genomic 1CP-DNA, three gene sets encoding three different two-component phenol hydroxylases pheA1/pheA2(1-3) could be identified. One of them was found to be located on the megaplasmid p1CP which confirms the role of these elements for metabolic versatility. Protein chromatography of phenol- and 4-chlorophenol-grown 1CP-biomass gave first evidences on a functional expression of these oxygenases, which could be initially characterised in respect of their substrate specificity.
