All multicellular organisms are in an arms-race against the vast armies of rapidly mutating microbial pathogens that are seeking access to their rich stores of nutrients. The challenges for the organism are two-fold. First to develop appropriate immune defense molecules, and second to generate the diversity needed to combat a rapidly changing pathogen population.
Immunologists have had much success in determining the varied means by which animals accomplish this, but this integrated vision of immunity generally does not stray across the line that divides animals from plants.
However, it is obvious that plants can resist many infectious disease agents very effectively, and in their article John McDowell and Stacey Simon from Virginia Polytechnic Institute and State University in Blacksburg, USA (Developmental and Comparative Immunology, doi:10.1016/j.dci.2007.11.005) review the multiple lines of defense that plants use against pathogenic microbes. Preliminary evidence leads them to conclude that the rate at which diversification occurs in the plant immune surveillance genes is stimulated by the presence of pathogens, a new and intriguing aspect of plant immunity.
“I have followed plant immunity research for quite some time and have seen the progress in this area. It is important to publish this article in our journal because it provides a very exciting immunological insight", said Kenneth Söderhäll, one of the Editors-in-Chief of the ISDCI journal.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
