What recognizes what in plant disease resistance?

... leucine-rich repeat domain, the authors show that association is mediated by a completely different region on N's Toll-interleukin-1 receptor homology domain, which is structurally similar to animal innate immunity molecules. These findings provide novel insights into how R proteins recognize pathogen Avr prote...

FSU researchers determine a critical factor in workings of proteins

...w theory has been proven to accurately predict the association rate for proteins. Their theory is outlined in the...tational Science and department of physics. "Rapid association between proteins is crucial in a wide array of biological processes, such as the utilization of and ...

Scientists find new genetic clue to cause of Alzheimer's disease

...nges in the SORL1 gene. Again, they found the same association between SORL1 variations and Alzheimer's disease. ...., Ph.D., of the Mayo Clinic further confirmed the association of SORL1 variations and Alzheimer's. "We are seeing the gene implicated in multiple data sets, acr...

Scientists discover a new risk factor for Alzheimer's

...Hyslop's team studied did not reveal a significant association between SORL1 and Alzheimer's. Non-SORL1 causes might have been overrepresented and SORL1-associated causes underrepresented in these data sets, St George-Hyslop explained. Alternatively, these data sets may have contained several different Alzheimer...

E. coli bacteria migrating between humans, chimps in Ugandan park

...s the result of direct or indirect (environmental) association between the chimps and humans working in the park. Both make use of local streams and other environmental features. Regardless of the route of transmission, it places both at risk, Goldberg said. "We’re as concerned about potential effects on ...

Reminding doctors which antibiotics to prescribe cuts C. difficile infection rates

...t broad-spectrum antibiotic use, despite the known association between these compounds and CDI. BACKGROUND Drugs such as cephalosporins---so-called broad-spectrum agents because of their action against many types of bacteria---damage normal intestinal flora in addition to killing disease-causing microbe...

Common parasitic infection leads to increased risk for HIV infection

...e first to demonstrate a statistically significant association between trichomoniasis and HIV infection. Trichomoniasis, caused by the parasite, Trichomonas vaginalis infects more than 170 million people worldwide each year. On its own, it usually does not cause serious complications. Some men may experience a ...

Genes and genius: Researchers confirm association between gene and intelligence

... they share an environment. But in spite of the association between genes and intelligence, it has been difficult to find specific variations that influence intelligence. The genes identified in the past were those that had profoundly negative effects on intelligence ?genes that cause mental retardation, for ...

"However, substantial evolutionary change may also occur in the absence of speciation, so basal species are not necessarily, or even likely a more conserved model of the ancestor. "We...

The strong association between PVL and CA-MRSA makes the toxin an excellent marker to track community strains, but the assumption that it is the major virulence determinant driving this epidemic is simply not true." These findings are significant because some infectious...
