An international team of scientists has developed a new technique to aid crops at risk from a devastating agricultural parasite commonly known as the 'honey fungus', one of the most serious diseases of trees and shrubs across the northern hemisphere. The development allows crop to be screened for natural resistance by adding DNA with fluorescent genes to the fungus before being planted out. The research, a collaboration between the United States Department of Agriculture's Agricultural...

Pathogenic fungi have been found to protect themselves against unwanted genetic mutations during sexual reproduction, according to researchers at Duke University Medical Center. A gene-silencing pathway protects the fungal genome from mutations imposed by a partner during mating. This pathway was discovered in Cryptococcus neoformans, a fungus that commonly infects humans, causing over one million cases of lung and brain infection each year, and more than 600,000 deaths. A related species,...

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...

An international team of scientists calls for protecting complementary food for infants in developing countries "“ especially those where corn is a staple food "“ against fumonisin, a toxin produced by fungi. Until now, physicians thought the growth retardation of children in those regions was to be blamed on the poor nutritional value of the complementary maize porridge they receive when breast milk is no longer sufficient. But toxins indeed are involved, the scientists report in...

A new breakthrough by scientists at the University of Sheffield has shed light on how the Earth's first plants began to colonise the land over 470 million years ago by forming a partnership with soil fungi. The research, which was published today (2 November 2010) in Nature Communications, has provided essential missing evidence showing that an ancient plant group worked together with soil-dwelling fungi to 'green' the Earth in the early Palaeozoic era, nearly half a billion years ago. The...

OMAHA, Neb., Oct. 29 /PRNewswire-USNewswire/ -- A Creighton University School of Medicine researcher has been awarded a $2.7 million grant by the National Institutes of Health (NIH) to investigate a possible link between the ingestion of tortillas and corn-based food products contaminated with a fungal toxin and increased risk for birth defects. The three-year award is a collaborative effort among investigators at Creighton, the U.S. Department of Agriculture-Agricultural Research Service...

They are one of the most highly prized delicacies in the culinary world, but now scientists have discovered that black truffles are locked in a gender war for reproduction. The research, published in New Phytologist as the truffle season begins, represents a breakthrough in the understanding of truffle cultivation and distribution. The teams, led by Dr Francesco Paolocci and Dr Andrea Rubini from the CNR Plant Genetics Institute in Perugia and by Dr Francis Martin from INRA in Nancy, carried...

Relationships among organisms, or mutualisms, might be more important to global ecosystem health than previously thought, argues a research team involving UA professor Judith Bronstein Mutually beneficial partnerships among species may play highly important but vastly underrecognized roles in keeping the Earth's ecosystems running, a group of evolutionary biologists suggests in a study. The authors present evidence that human impacts may be forcing these mutualist systems down unprecedented...

University of North Carolina, Greensboro researchers are studying native grasses to develop a better understanding of the workings of fungal endophytesLegend has it that five railroad surveyors killed by Indians in 1854 in New Mexico lost their lives because they unwittingly allowed their horses to graze on "sleepy grass" the night before. The next morning, under attack, the surveyors jumped on their horses to escape--but the animals were frozen in place. Without the means for a quick...

Scientists will investigate forest change, marine viruses, honey bees, stream biodiversity, evolutionary history Despite centuries of discovery, most of our planet's biodiversity remains unknown. The scale of that unrecognized biodiversity is a vital question, scientists believe, given its rapid and permanent loss around the globe. To respond to the need for more knowledge and a better understanding of Earth's biodiversity, the National Science Foundation (NSF) has awarded 14 grants in its...

Leafcutter ants are found in warmer regions of Central and South America. These remarkable social insects have evolved an advanced agricultural system. They feed on a specialized fungus that grows only in the underground chambers of the ants' nest. The ants actively cultivate their fungus, feeding it with freshly-cut vegetation and maintaining it free from pests and weeds. This is done by a symbiotic relationship with a colony of bacteria that grows on the ants that protect the fungus. The...
