Scientists isolate world's oldest recorded plant virus
A Japanese poem written by Empress Koken, in the summer of 752AD, is thought to be the world's first record of a plant virus. Scientists from the John Innes Centre in Norwich (JIC)(1) have today reported, for the first time, the isolation and characterisation of the plant virus (eupatorium yellow... view more (2003-04-25)

Whitefly spreads emerging plant viruses
A tiny whitefly is responsible for spreading a group of plant viruses that cause devastating disease on food, fiber, and ornamental crops, say plant pathologists with The American Phytopathological Society (APS).   view more (2007-01-19)

Genes identified to protect brassicas from damaging disease
Scientists have identified a new way to breed brassicas, which include broccoli, cabbage and oilseed rape, resistant to a damaging virus.   view more (2007-11-01)

Discovery in plant virus may help prevent HIV and similar viruses
In a study that could lead to new ways to prevent infection by human immunodeficiency virus (HIV) and similar organisms, Purdue University researchers have been able to genetically modify a plant to halt reproduction of a related virus.   view more (2007-08-01)

West Nile virus antibodies sought in birds in England
Scientists at the Centre for Ecology and Hydrology at Oxford are investigating live birds to see whether or not West Nile virus is present and being actively transmitted between resident and migratory birds. No infectious virus has as yet been detected. The birds sampled were healthy, implying... view more (2002-10-31)

Structure of the yellow rice mottle virus determined for the first time
Scientists from IRD (Institut de recherche pour le développement, ex-ORSTOM), the Scripps Research Institute and the International Laboratory for Tropical Agricultural technology (ILTAB) have succeeded, after several years of research, in reconstructing a three-dimensional model of the rice... view more (2001-01-26)

More than drought affecting wheat yields
Wheat producers have more than the drought cutting into their yields this year, said two Texas Agricultural Experiment Station researchers.   view more (2006-06-07)

An unexpected outcome of atmospheric CO2 enrichment
Unseen belowground interactions impact the composition of natural plant communities. Mycorrhizae, symbiotic associations between soil fungi and plant roots, help plants acquire soil nutrients but also drain substantial carbon from plants. Whether mycorrhizae help or hinder plant growth depends upon... view more (2003-05-22)

Genome circularization and RNA virus replication
As featured on the cover of the August 15th issue of G&D, an Argentinian research team, led by Dr. Andrea Gamarnik, report on their recent discovery of a novel mechanism of dengue virus replication.   view more (2006-08-01)

Rotavirus can spread beyond the intestine
A new study in PLoS Medicine has shown that children who have rotavirus, a very common cause of diarrhea in children, and who have antigens (protein fragments from the surface of the virus) in their blood, also have infectious virus in their blood.   view more (2007-04-17)

Avian flu virus unlikely to spread through wastewater and drinking water treatment systems, Cornell researchers find
A close relative of the highly pathogenic avian influenza virus (H5N1) can be eliminated by waste and drinking water treatments, including chlorination, ultraviolet (UV) radiation and bacterial digesters. The virus is harmless to humans but provides a study case of the pathways by which the... view more (2007-01-04)

West Nile Virus infections detected in Britain
A paper in the Journal of General Virology reveals that evidence of West Nile virus infections has been found in birds in Britain, according to a team of scientists led by the Centre for Ecology and Hydrology (CEH) at Oxford. There are no known cases of human infection and no disease reported in... view more (2003-07-18)

Battling virus disease of watermelon with bottlegourds
New help may be on the way for beleaguered growers of popular cucurbit crops like cucumbers and watermelons. Many varieties of the widely grown bottlegourd (Lagenaria siceraria) appear to have resistance to Zucchini yellow mosaic virus (ZYMV), a scourge of commercial cucurbits that includes... view more (2007-10-03)

Molecular Anatomy of Influenza Virus Detailed
Scientists at the National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), part of the National Institutes of Health in Bethesda, Md., and colleagues at the University of Virginia in Charlottesville have succeeded in imaging, in unprecedented detail, the virus that causes... view more (2007-01-02)

Scientists discover new species of Ebola virus
Scientists report the discovery of a new species of Ebola virus, provisionally named Bundibugyo ebolavirus, November 21 in the open-access journal PLoS Pathogens.   view more (2008-11-21)

FURTHER STEPS TOWARDS A VACCINE AGAINST HIV
For white blood cells in the human body to be infected by the HIV virus, proteins in the virus must be allowed to interact with a number of different components on the surface of the white blood cell. Ideally anti-HIV preventive therapy or vaccines would prevent several of these interactions taking... view more (1999-03-11)

Thale cress goes on the defensive
Thale cress has a complicated defence technique against insects and microorganisms that use the plant as a source of food.   view more (2007-05-15)

UC Riverside Researchers Discover Model Organism For Studying Viruses that Affect Humans
Researchers at the University of California, Riverside have discovered that a simple worm, called C. elegans, makes an excellent experimental host for studying some of the most virulent viruses that infect humans.    view more (2005-08-18)

New host species for avian influenza identified
In a new study published online in the open-access journal PLoS Pathogens, Dr. Vincent J. Munster, of Erasmus Medical Center, Rotterdam, and colleagues identify new host species for avian influenza A virus (H5N1) and provide important information on the distinctions between the ecology and... view more (2007-05-11)

Bee disease a mystery
Scientists are one step closer to understanding the recent demise of billions of honey bees after making an important discovery about the transmission of a common bee virus.   view more (2008-06-30)

Grazer diversity counteracts plant diversity effects on ecosystem functioning in seagrass beds
Several influential experiments have shown that high plant diversity enhances ecosystem productivity, animal diversity, and invasion resistance. Yet theory predicts that plant and herbivore diversity, which often co vary in nature, should have countervailing effects on ecosystem properties. In the... view more (2003-07-02)

Sick Beans lead to Nanotech
Plant viruses as chemically "programmable" building blocks for nanobiotechnology Farmers get little joy from the cowpea mosaic virus, which attacks legumes. Chemists and molecular biologists at the Scripps Institute in La Jolla are, on the other hand, completely taken with this virus. They are not... view more (2002-02-05)

Seed banks preserve plant diversity
'Some seed gene banks contain more higher plant species per square meter than anywhere else on the planet', write Simon Linington and colleagues of the Millenium Seed Bank, Kew, in the October issue of Biologist. This helps to 'ensure plant diversity is available long term for use in development or... view more (2003-10-02)

New virus threatens High Plains wheat crop
Triticum mosaic virus poses a new threat to Texas wheat, according to Texas AgriLife Research scientists in Amarillo.   view more (2008-08-22)

Catastrophic shift in species diversity and productivity of an ecosystem
Ecology and environmental management is largely predicated on the view that ecosystems respond to environmental changes in a smooth and straightforward way. However, in Ecology Letters, May, Schmitz reports on a long-term field experiment that may prompt a hard, critical look at this reigning view.... view more (2004-05-04)
