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...

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...

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...

This discovery may generate new strategies to fight serious human diseases, and devastating plant blights--including the type of blight involved in the Irish Potato Blight. A study published in the July 23 issue of Cell identifies the mechanism used by several types of common, virulent microbes to infect plants and cause devastating blights. Microbes using this infection mechanism include fungi that are currently causing wheat rust epidemics in Africa and Asia, and a class of parasitic algae,...

In the battle against soil fungi that discolor horseradish roots and can render the entire crop unsellable, University of Illinois researcher Mohammad Babadoost found that subjecting the roots to hot water before planting was most effective in killing the pathogen in propagative root stocks. The final recipe: submerge in water heated to 47 degrees Centigrade for 20 minutes. Babadoost was looking for a reliable, non-chemical method to control Verticillium and Fusarium "“ soil-borne fungi...

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...

Wild potato germplasm that offers resistance to some major potato diseases has been identified by Agricultural Research Service (ARS) scientists. Geneticists Dennis Halterman and Shelley Jansky pinpointed the resistant wild potato species in studies at the ARS Vegetable Crops Research Unit in Madison, Wis. Halterman has identified a wild potato species called Solanum verrucosum that contains a gene with resistance to late blight, considered the most destructive disease of potato. The wild...

Researchers at the Public University of Navarra, the Polytechnic University of Madrid (CBGP), the University of Malaga, the University of Wisconsin and the Valencian Institute of Agricultural Research have managed to sequence the genome of the bacteria responsible for tuberculosis in the olive tree. The study, included in the June issue of Environmental Microbiology, represents the first sequencing of the genome of a pathogenic bacteria undertaken in Spain, being the first genome known...

Findings could lead to new strategies for sustainable agriculture and biofuel production You might think bacteria that "invade" trees are there to cause certain destruction. But like the helpful bacteria that live within our guts, some microbes help plants thrive. To find out what makes these microbe-plant interactions "tick," scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory decoded the genome of a plant-dwelling microbe they'd previously shown could increase...

Soybean Cyst Nematode, Heterodera glycines
2014-01-12 00:00:00

The soybean cyst nematode (Heterodera glycines) is a parasitic worm that infects soybean plants, and other legumes, across the world. It is thought to be native to Asia, but was found in the United States in 1954 and in Colombia in the 1980’s. It can be found in Italy and Iran and its most recent sightings have occurred in Brazil and Argentina, two major areas where soybeans are grown. These worms are highly damaging to American soybean crops, costing the industry as much as 500 thousand...
