Diverse and abundant phages exploit conjugative plasmids.

Phages exert profound evolutionary pressure on bacteria by interacting with receptors on the cell surface to initiate infection. While the majority of phages use chromosomally encoded cell surface structures as receptors, plasmid-dependent phages exploit plasmid-encoded conjugation proteins, making their host range dependent on horizontal transfer of the plasmid. Despite their unique biology and biotechnological significance, only a small number of plasmid-dependent phages have been characterized.

Exploration of Social Spreading Reveals That This Behavior Is Prevalent among and Pseudomonas fluorescens Isolates and That There Are Variations in the Induction of the Phenotype.

Within soil, bacteria are found in multispecies communities, where interactions can lead to emergent community properties. Studying bacteria in a social context is critical for investigating community-level functions. We previously showed that cocultured Pseudomonas fluorescens Pf0-1 and sp.

Interspecies Social Spreading: Interaction between Two Sessile Soil Bacteria Leads to Emergence of Surface Motility.

Bacteria often live in complex communities in which they interact with other organisms. Consideration of the social environment of bacteria can reveal emergent traits and behaviors that would be overlooked by studying bacteria in isolation. Here we characterize a social trait which emerges upon interaction between the distantly related soil bacteria Pf0-1 and sp.

Draft Genome Sequence of sp. Strain SL1, a Putative Polyhydroxyalkanoate-Producing Halophile.

Halomonas sp. strain SL1, a halophilic gammaproteobacterium, was isolated from samples from the Great Salt Lake in Utah. We report here the draft genome sequence of SL1, which has an estimated total sequence length of 3.

Draft Genome Sequence of Ralstonia sp. MD27, a Poly(3-Hydroxybutyrate)-Degrading Bacterium, Isolated from Compost.

Ralstonia sp. strain MD27, a novel biopolymer-degrading betaproteobacterium, was isolated from compost samples. This organism has been shown to utilize the biopolymer poly(3-hydroxybutyrate) [P(3HB)] as a carbon source for growth.

Draft Genome Sequences of Pseudomonas fluorescens Strains SF39a and SF4c, Potential Plant Growth Promotion and Biocontrol Agents.

Pseudomonas fluorescens SF4c and SF39a, strains isolated from wheat rhizosphere, have potential applications in plant growth promotion and biocontrol of fungal diseases of crop plants. We report the draft genome sequences of SF4c and SF39a with estimated sizes of 6.5 Mb and 5.

Draft Genome Sequence of Rice Isolate Pseudomonas chlororaphis EA105.

Pseudomonas chlororaphis EA105, a strain isolated from rice rhizosphere, has shown antagonistic activities against a rice fungal pathogen, and could be important in defense against rice blast. We report the draft genome sequence of EA105, which is an estimated size of 6.6 Mb.
