BACTERIAL AVIRULENCE GENES

Annual Review of Phytopathology, 1996
▪ Abstract  Although more than 30 bacterial avirulence genes have been cloned and characterized, the function of the gene products in the elictitation of resistance is unknown in all cases but one. The product of avrD from Pseudomonas syringae pv. glycinea likely functions indirectly to elicit resistance in soybean, that is, evidence suggests the gene

Visualization of Bacterial Genes in Action

Science, 1970
The 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 ...

Noise in bacterial gene expression

Biochemical Society Transactions, 2018
Abstract The expression level of a gene can fluctuate significantly between individuals within a population of genetically identical cells. The resultant phenotypic heterogeneity could be exploited by bacteria to adapt to changing environmental conditions.

Bacterial Gene Expression and Biotechnology

1985
This 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.

Homology among bacterial catalase genes

Canadian Journal of Microbiology, 1990
Catalase activities in crude extracts of exponential and stationary phase cultures of various bacteria were visualized following gel electrophoresis for comparison with the enzymes from Escherichia coli. Citrobacter freundii, Edwardsiella tarda, Enterobacter aerogenes, Klebsiella pneumoniae, and Salmonella typhimurium exhibited patterns of catalase ...

Bringing gene order into bacterial shape

Trends in Genetics, 2001
A 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.

Two kinds of insertions in bacterial genes

Molecular and General Genetics MGG, 1972
Six insertion mutations in the gal operon of E. coli and two insertion mutations in the xycIIOP operon of bacteriophage lambda were tested for homology by annealing separated strands of lambda dgal DNA carrying the insertions, and inspection in the electron microscope.

Bacterial genes in humans?

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).
