Bacterial gene expression at low temperatures
Extremophiles, 2012Under suboptimal environmental conditions such as low temperatures, many bacteria have an extended lag phase, altered cell structures, and composition such as a less fluid (more rigid) and leaky cytoplasmic membrane. As a result, cells may die, enter into a starvation mode of metabolism or a physiologically viable but non-culturable (VBNC) state.

Bacterial Gene Expression and Biotechnology
1985This brief review article has been intended to give a few up-to-date examples of the dramatic impact that our knowledge of gene expression (especially bacterial gene expression) has had in the area of biotechnology. This area is in a state of such rapid growth that it has only been possible to present a limited overview of the subject matter.

Bacterial plant oncogenes: Therol genes' saga
Genetica, 1994The rol genes are part of the T-DNA which is transferred by Agrobacterium rhizogenes in plant cells, causing neoplastic growth and differentiation. Each of these bacterial oncogenes deeply influences plant development and is finely regulated once transferred into the plant host.

Bringing gene order into bacterial shape
Trends in Genetics, 2001A different arrangement of a cluster of genes involved in division and cell-wall synthesis separates bacilli from other bacteria in a phylogenetic analysis. We conclude that the relationships between these genes are not random and might reflect significant events in the evolution of the coupling between growth and division in bacteria.

Ectopic gene conversions in bacterial genomes
Genome, 2007We characterized the gene conversions found between the duplicated genes of 75 bacterial genomes from five species groups (archaea, nonpathogenic and pathogenic firmicutes, and nonpathogenic and pathogenic proteobacteria). The number of gene conversions is positively correlated with the size of multigene families and the size of multigene families is ...

Visualization of Bacterial Genes in Action
Science, 1970The morphology of active structural and putative ribosomal RNA genes was observed by electron microscopy after lysis of fragile Escherichia coli cells. Conclusions drawn are: most of the chromosome is not genetically active at any one instant; translation is completely coupled with transcription; the 16 ...

Trends in Biotechnology, 2001
In the June issue of Trends in Biotechnology, we reported on a paper in Science (Steven Salzberg et al., 8 June) that cast doubt on the original conclusions of the two human genome sequence reports (Nature, 15 February and Science, 16 February).

Bacterial polysaccharide synthesis and gene nomenclature
Trends in Microbiology, 1996Gene nomenclature for bacterial surface polysaccharides is complicated by the large number of structures and genes. We propose a scheme applicable to all species that distinguishes different classes of genes, provides a single name for all genes of a given function and greatly facilitates comparative studies.

Dynamics of Bacterial Gene Regulatory Networks
Annual Review of Biophysics, 2018The ability of bacterial cells to adjust their gene expression program in response to environmental perturbation is often critical for their survival. Recent experimental advances allowing us to quantitatively record gene expression dynamics in single cells and in populations coupled with mathematical modeling enable mechanistic understanding on how ...
