Stress-induced proteins of Agrobacterium tumefaciens

FEMS Microbiology Ecology
Ran RosenEliora Z Ron

Abstract

The pattern of proteins produced by bacteria represents the physiological state of the organism as well as the environmental conditions encountered. Environmental stress induces the expression of several regulons encoding stress proteins. Extensive information about the proteins which constitute these regulons (or stimulons) and their control is available for very few bacteria, such as the Gram-positive Bacillus subtilis and the Gram-negative Escherichia coli (gamma-proteobacteria) and is minimal for all other bacteria. Agrobacterium tumefaciens is a Gram-negative plant pathogen of the alpha-proteobacteria, which constitutes the main tool for plant recombinant genetics. Our previous studies on the control of chaperone-coding operons indicated that A. tumefaciens has unique features and combines regulatory elements from both B. subtilis and E. coli. Therefore, we examined the patterns of proteins induced in A. tumefaciens by environmental changes using two-dimensional gel electrophoresis and dual-channel image analysis. Shifts to high temperature, oxidative and mild acid stresses stimulated the expression of 97 proteins. The results indicate that most of these stress-induced proteins (80/97) were specific to one stress stimulon....Continue Reading

Trending Feeds

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
