University of Zurich Powdery mildew is one of the most dreaded plant diseases: The parasitic fungus afflicts crops such as wheat and barley and is responsible for large harvest shortfalls every year. Beat Keller and Thomas Wicker, both plant biologists from the University of Zurich, and their team have been analyzing the genetic material of wheat mildew varieties from Switzerland, England and Israel while the team headed by Paul Schulze-Lefert at the Max Planck Institute for Plant Breeding...

Plants, too, have an immune system that protects them against diseases. The early detection of pathogens and the subsequent immune response, in particular at the cell wall, work as a protective shield. However, the pathogens that cause plant diseases have their weapons, too. Some are able to suppress the natural cell wall reaction in plants. "One particularly ingenious attacker, powdery mildew, can even reprogram cells in such a way that they adapt their architecture and metabolism to...

CONKLIN, N.Y., June 30, 2011 /PRNewswire/ -- Does a company garden make sense? It does when the company growing the garden specializes in distributing a fungicide. "All the employees have pitched in; from starting seeds a few months ago, to digging the garden and planting, it's been a team effort," says Pete Yeager, President of GreenCure Solutions. "It's a nice diversion in the middle of a busy day to step outside and check on the garden." The garden gives the company the opportunity...

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...

Scientists have sequenced the genome of a major fungal disease that affects barley and other cereal crops, a breakthrough that could lead to significant advances in our understanding of how plant diseases evolve Scientists have sequenced the genome of a major fungal disease that affects barley and other cereal crops, a breakthrough that could lead to significant advances in our understanding of how plant diseases evolve. The research, published today in the journal Science, suggests that...

University of Missouri researchers study traits that make Norton grapes resistant to debilitating mildew In a few years, a sip of Cabernet Sauvignon, Merlot or Pinot Noir may include a taste of the "Show-Me" State. The state grape of Missouri "“ the Norton variety grown at many vineyards around the state "“ is resistant to powdery mildew, a fungal pathogen that affects winemaking grapes around the world. Now, researchers at the University of Missouri are working to identify...

Two proteins involved in powdery mildew infection in plants also play an important role in fertilisation Mildew infections not only cause unsightly vegetable patches, they can also result in extensive crop failure. Interestingly, the processes involved in infections with this garden pest are similar to those involved in fertilisation. Scientists from the Max Planck Institute for Plant Breeding Research in Cologne and the University of Zurich have identified two proteins in the model plant...

Powdery mildew is a fungus that infects both crop and ornamental plants. Each year, powdery mildew and other plant pathogens cause immense crop loss. Despite decades of intense research, little is known of the plant molecules that allow fungal hyphae to invade the host's epidermal cells. A European research group lead by Ueli Grossniklaus, a plant geneticist at the University of Zurich, now published a study in Science shedding a new light on mildew susceptibility in plants and its surprising...

STANFORD, CA "“ Like waves of soldiers guarding a castle gate, multiple genetic defenders cooperate to protect plant cells against powdery mildew disease, according to a new study. Powdery mildew is a common fungal infection in plants that attacks more than 9,000 species, including many crops such as barley and wheat, and horticultural plants such as roses and cucumbers. The researchers, including Shauna Somerville and M³nica Stein of the Carnegie Institution's Department of Plant...
