چکیده

The regulation of Agrobacterium tumefaciens heat shock genes involves a transcriptional activator (RpoH) and repressor elements (HrcA-CIRCE). Using proteome analysis and mutants in these control elements, we show that the heat shock induction of 32 (out of 56) heat shock proteins is independent of RpoH and HrcA. These results indicate the existence of additional regulatory factors in the A. tumefaciens heat shock response.

The dnaKJ operon of Agrobacterium tumefaciens: transcriptional analysis and evidence for a new heat shock promoter.

The dnaKJ operon of Agrobacterium tumefaciens was cloned and sequenced and was found to be highly homologous to previously analyzed dnaKJ operons. Transcription of this operon in A. tumefaciens was stimulated by heat shock as well as by exposure to ethanol and hydrogen peroxide. There were two transcripts representing the dnaKJ operon: one containing the dnaK and dnaJ genes and the second conta...

The groESL operon of Agrobacterium tumefaciens: evidence for heat shock-dependent mRNA cleavage.

The heat shock response of the groESL operon of Agrobacterium tumefaciens was studied at the RNA level. The operon was found to be activated under heat shock conditions and transcribed as a polycistronic mRNA that contains the groES and groEL genes. After activation, the polycistronic mRNA appeared to be cleaved between the groES and groEL genes and formed two monocistronic mRNAs. The groES cle...

Proteome analysis in the study of the bacterial heat-shock response.

In recent years, it has become clear that, in addition to the regulation of the expression of specific genes, there are global regulatory systems that control the simultaneous expression of a large number of genes in response to a variety of environmental stresses. The first of these global control systems, and of substantial importance, is the heat-shock response. The heat-shock response is ch...

Heat shock activation of the groESL operon of Agrobacterium tumefaciens and the regulatory roles of the inverted repeat.

Deletions were constructed in the conserved inverted repeat (IR) found in the groESL operon of Agrobacterium tumefaciens and in many other groE and dnaK operons and genes in eubacteria. These deletions affected the level of expression of the operon and the magnitude of its heat shock activation. The IR seems to operate at the DNA level, probably as an operator site that binds a repressor under ...

Bacteriophage release in a lysogenic strain of Agrobacterium tumefaciens.

Bacteriophage release in a lysogenic strain of Agrobacterium tumefaciens V-1 is temperature-sensitive. At 25 C and 30 C, phage was released in a ratio of 1 plaque-forming unit per 100 bacteria; at 35 C, although bacterial growth was not inhibited, phage release was suppressed. Phage synthesis was induced by heat shock, 42 C for 30 min, ultraviolet irradiation, and mitomycin C. Induction by ultr...
