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...

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...

Timing is everything in the long-standing arms race between the flowering plant Arabidopsis and Hyaloperonospora, a downy mildew pathogen. Duke University researchers have found that the little mustard plant cranks up its immune system in the morning to prepare for the greatest onslaught of infectious spores released by the mildew. It isn't news that plants know what time of day it is and change their activities accordingly, but this is the first time that a plant's defensive systems have...

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...

New research finds that crop-killing mildews are able to sneak into plants undetected as "stealth bombers" by shedding genes to conceal themselves thus thwarting the plants' defenses. In a pair of studies, researchers mapped the genomes of two of the plant-killing mildews, and then described how the diseases shed giveaway genes to trigger an immune attack in the host plants. Although powdery mildew plagues seem to come out of nowhere,  they can devastate barley, corn, grapes, potatoes...
