Crop Killing Fungi
2012-10-19 05:11:14

April Flowers for redOrbit.com - Your Universe Online An enormous international team of experts, almost 500 members strong, has developed a ranking system of the ten most important phytopathogenic fungi on a scientific and economic level. Topping the list is the rice blast fungus Magnaporthe oryzae. A survey conducted among the researchers resulted in a list of the most important phytopathogenic fungi, with each researcher choosing three that he or she thought most significant. The...

Plant Has Bacterial Community Inside The Root
2012-08-03 12:17:17

Plants choose the soil bacteria that they allow into their roots Soil is the most species-rich microbial ecosystem in the world. From this incredible diversity, plants specifically choose certain species, give them access to the root and so host a unique, carefully selected bacterial community from which they then benefit in a variety of ways. To achieve this, the plant's immune system must be able to tell which of these bacteria are friends and which foes. Researchers from the Max Planck...

Researchers have identified the set of tools an infectious microbe uses to persuade a plant to open the windows and let the bug and all of its friends inside. The microbe is Pseudomonas syringae, a successful bacterial pathogen that produces characteristic brown spots in more than 50 different species of plant. The signal it uses is a molecule called coronatine, which to the plant looks just like its own jasmonic acid, a signal that is part of the plant's immune system. The pathogen...

More than 600 million people could be fed each year by halting the spread of fungal diseases in the world's five most important crops, according to research published today in the journal Nature. Furthermore, data reviewed by scientists suggests that in 70% of cases where infectious disease causes the extinction of a type of animal or plant, an emerging species of fungus is behind the problem. Evidence suggests this figure is increasing. The scientists behind the study, from the...

From improving food security to their use as biotechnology power horses, Trichoderma fungi are increasingly being exploited by industry. Current advances in the field are brought together and highlighted in a special issue of Microbiology published online on 27 December. Trichoderma are free-living fungi widely used in agricultural biotechnology. Some species of Trichoderma are specifically used as biocontrol agents to control plant pathogens including Fusarium species. Their success is...

A protein called enhanced disease susceptibility 1 (EDS1) plays a central role in plants' ability to defend themselves from pathogens. But in the almost two decades since it was discovered, how EDS1 works at the molecular level has been a mystery. Solving the mystery will help scientists enhance disease resistance in crops. Two papers published in the Dec. 9 issue of Science (http://www.sciencemag.org/magazine) demonstrate how EDS1 activates different components of the plant immune system,...

Discovery could lead to improved disease resistance in food crops Researchers at the University of Missouri have found a key process in a plant's immune system response that may help future crops fight off dangerous diseases. "We study how Arabidopsis, a common weed related to the mustard plant, fends off infectious agents," said Walter Gassmann, professor of plant sciences and researcher for the Christopher S. Bond Life Sciences Center and Interdisciplinary Plant Group. "We have...

Planting tall fescue grass as a ground cover in peach orchards helps protect peach trees from nematodes that attack tree roots, according to U.S. Department of Agriculture (USDA) scientists. In a study published in the Journal of Nematology in 2010, Agricultural Research Service (ARS) plant pathologists Andy Nyczepir at the Southeastern Fruit and Tree Nut Research Laboratory in Byron, Ga., and Susan Meyer at the Nematology Laboratory in Beltsville, Md., tested several tall fescue varieties...

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...
