University of Oxford Scientists have discovered vital clues as to how the pathogen responsible for the Irish potato famine adapted to spread between different plant species. Researchers at Oxford University and The Sainsbury Laboratory (Norwich, UK) looked in unprecedented detail at how Phytophthora infestans, a pathogen that continues to blight potatoes and tomatoes today, evolved to target other plants. The study, published today in the journal Science, is the first to show how...

Max-Planck-Gesellschaft An international team of scientists reveals that a unique strain of potato blight they call HERB-1 triggered the Irish potato famine of the mid-19th century It is the first time scientists have decoded the genome of a plant pathogen and its plant host from dried herbarium samples. This opens up a new area of research to understand how pathogens evolve and how human activity impacts the spread of plant disease. Phytophthora infestans changed the course of...

Research by UC Riverside plant pathologists is the first to show that RNA silencing regulates plant defense against the notorious Phytophthora pathogens When a pathogen attacks a plant, infection usually follows after the plant´s immune system is compromised. A team of researchers at the University of California, Riverside focused on Phytophthora, the pathogen that triggered the Irish Famine of the 19th century, and deciphered how it succeeded in crippling the potato plant´s...

Pacific Southwest Research Station/USDA Forest Service Science that makes a difference... Climate change is projected to have far-reaching environmental impacts both domestically and abroad. A recently published report by the USDA Forest Service's Pacific Southwest Research Station (PSW) examines the impact of climate change on forest diseases and how these pathogens will ultimately affect forest ecosystems in the Western United States and Canada. Drawing on a large body of published...

Scientists are reporting a key advance toward development of a way to combat the terrible plant diseases that caused the Irish potato famine and still inflict billions of dollars of damage to crops each year around the world. Their study appears in ACS' bi-weekly journal Organic Letters. Teck-Peng Loh and colleagues point out that the Phytophthora fungi cause extensive damage to food crops such as potatoes and soybeans as well as to ornamental plants like azaleas and rhododendrons. One...

Scientists recommend effective treatment for spraying pear trees Diseases caused by a species of fungus called Phytophthora syringae are responsible for significant economic losses on a wide range of plants, including pear. In the Pacific Northwest region of the United States, disease occurs during the winter in nursery stock, especially on trees that are harvested and stored in coolers or in outdoor sawdust beds. Recent field observations by growers suggest that increased nitrogen content in...

10-year cooperative research effort provides basis for containment Synthesizing more than 10 years of cooperative research on the exotic invasive, quarantine sudden oak death pathogen, the USDA Forest Service's Pacific Southwest Research Station (PSW) recently published "Sudden Oak Death and Phytophthora ramorum: A Summary of the Literature." This 181-page comprehensive report covers a wide range of topics, including a history of sudden oak death, identification and distribution of the...

Wet conditions have Illinois pumpkin growers on the alert for signs of Phytophthora blight in their fields. This disease nearly destroyed the pumpkin industry in 1999, causing up to 100 percent crop losses in parts of the state. While it's not a new disease to this industry, it is the most devastating and it's already showing up in Illinois. Mohammad Babadoost, University of Illinois Extension specialist in fruit and vegetable pathology, said, "An outbreak of Phytophthora blight in Illinois...

Potatoes offering elevated levels of phytonutrients thought to promote health could add a new dimension to the consumer diet. But the journey from farm to fork can be a perilous one fraught with sundry microorganisms ready to attack the spuds, either while they're still in the ground or during storage. In Aberdeen, Idaho, Agricultural Research Service (ARS) scientists Rich Novy and Jonathan Whitworth are taking on the late-blight fungus, Phytophthora infestans, best known for its role in the...
