Latest Secretion Stories
In order to interact with the environment, bacteria secrete a whole arsenal of proteins. Researchers have now found how one of the transportation systems used for this purpose – the type VI secretion system – works for the single-celled organism Agrobacterium tumefaciens.
Bacteria have evolved different systems for secreting proteins into the fluid around them or into other cells.
Scientists from Queen Mary, University of London have discovered the workings behind some of the bacteria that kill hundreds of thousands every year, possibly paving the way for new antibiotics that could treat infections more effectively.
A team of biologists at the University of York has made an important advance in our understanding of the way cholera attacks the body.
All living organisms are made up of cells, behind these intricate life forms lie complex cellular processes that allow our bodies to function.
Carnegie Mellon University researchers have discovered that an element commonly found in nature might provide a way to neutralize the potentially lethal effects of a compound known as Shiga toxin.
Single-celled bacteria communicate with each other using coded messages to coordinate attacks on their targets.
A protein called enhanced disease susceptibility 1 (EDS1) plays a central role in plants' ability to defend themselves from pathogens.
Agrobacterium tumefaciens is the causal agent of crown gall disease (the formation of tumours) in over 140 species of dicot. It is rod shaped. Symptoms are caused by the insertion of a small segment of DNA into the plant cell. It is an alphaproteobacterium of the family Rhizobiaceae which includes the nitrogen fixing legume symbionts. They are pathogenic and provide no benefit to the plant. It also affects a wide variety of plants. In an economical sense it affects walnuts, grape vines,...
