As a major food source for much of the world, rice is one of the most important plants on earth.
Both plant and human diseases that can travel with the wind have the potential to spread far more rapidly than has been understood, according to a new study, in findings that pose serious concerns not only for some human diseases but also a new fungus that threatens global wheat production.
Canadian scientists say they've created a new class of green fungicides to provide a more environmentally friendly alternative to conventional fungicides. The University of Saskatchewan researchers led by Professor Soledade Pedras say their new fungicides -- called paldoxins -- can duplicate the work of conventional pesticides in helping protect corn, wheat and other crops that are used for food and biofuel production.
Exploiting a little-known punch/counterpunch strategy in the ongoing battle between disease-causing fungi and crop plants, scientists in Canada are reporting development of a new class of "green" fungicides that could provide a safer, more environmentally-friendly alternative to conventional fungicides.
Phytophthora blight, caused by Phytophthora capsici, is a major plant disease that affects many crop species worldwide, including chile peppers in New Mexico. Farmers' observations suggested that Phytophthora capsici caused less damage in pepper crops of the hot pepper varieties than low-heat pepper varieties.
North Carolina State University scientists and colleagues have completed the genome sequence and genetic map of one of the world's most common and destructive plant parasites â€“ Meloidogyne hapla, a microscopic, soil-dwelling worm known more commonly as the northern root-knot nematode.
By Marina, Maria Maiale, Santiago Javier; Rossi, Franco Ruben; Romero, Matias Fernando; Rivas, Elisa Isabel; Garriz, Andres; Ruiz, Oscar Adolfo; Pieckenstain, Fernando Luis The role of polyamine (PA) metabolism in tobacco (Nicotiana tabacum) defense against pathogens with contrasting pathogenic strategies was evaluated.

Virginia Tech scientists say that there has been a change in the status of the fungus causing Asian Soybean Rust but that the new information is still too preliminary for any action on the part of the Commonwealth's soybean producers.
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...
