Plants May Use Newly Discovered Language To Communicate
2014-08-15 03:42:31

[ Watch The Video: Attack Of The Parasitic Plants! ] Virginia Tech The discovery throws open the door to a new arena of science that explores how plants communicate with each other on a molecular level A Virginia Tech scientist has discovered a potentially new form of plant communication, one that allows them to share an extraordinary amount of genetic information with one another. The finding by Jim Westwood, a professor of plant pathology, physiology, and weed science in the...

Scientific program features the connections between healthy plants and world food availability and security. St. Paul, Minnesota (PRWEB) August 06, 2014 Plant health scientists from around the globe will gather August 9–13 at the Joint Meeting of The American Phytopathological Society (APS) and The Canadian Phytopathological Society (CPS) at the Minneapolis Convention Center in Minneapolis, Minnesota. The 2014 APS-CPS Joint Meeting theme is “Plant Health Connections,” providing the...

UC Riverside-led team describes the strategy by which Botrytis cinerea blocks the defense system of its host plants A research team led by a molecular plant pathologist at the University of California, Riverside has discovered the mechanism by which an aggressive fungal pathogen infects almost all fruits and vegetables. The team discovered a novel "virulence mechanism" — the mechanism by which infection takes place — of Botrytis cinerea. This pathogen can infect more than 200 plant...

Sexual Reproduction Second Choice For Powdery Mildew
2013-07-15 12:33:46

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...

Rice Blast Research A Step Closer To Controlling Devastating Crop Diseases
2013-06-18 11:57:00

University of Exeter Like a stealthy enemy, blast disease invades rice crops around the world, killing plants and cutting production of one of the most important global food sources. Now a study by an international team of researchers has shed light on how the rice blast fungus, Magnaporthe oryzae, invades plant tissue. The finding is a step towards learning how to control the disease, which by some estimates destroys enough rice to feed 60 million people annually. The team, from the...

Cause Of The Irish Potato Famine Revealed
2013-05-21 11:53:17

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...

While most farmers consider viruses and fungi potential threats to their crops, these microbes can help wild plants adapt to extreme conditions, according to a Penn State virologist. Discovering how microbes collaborate to improve the hardiness of plants is a key to sustainable agriculture that can help meet increasing food demands, in addition to avoiding possible conflicts over scare resources, said Marilyn Roossinck, professor of plant pathology and environmental microbiology, and...

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...

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...
