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...

U.S. Department of Agriculture (USDA) scientists in Athens, Georgia, have reported for the first time that several species of Aspergillus niger, or black aspergilli, are capable of infecting corn and peanuts as endophytes. The researchers also showed that, under laboratory conditions, these species produced mycotoxins. Using a molecular procedure they developed, USDA Agricultural Research Service (ARS) research leader Charles Bacon, microbiologist Dorothy Hinton, and Edwin Palencia, a...

By Robert Sanders, UC Berkeley Hydrodynamic model of spore plumes explains how plume gives spores an extra oomph Long before geese started flying in chevron formation or cyclists learned the value of drafting, fungi discovered an aerodynamic way to reduce drag on their spores so as to spread them as high and as far as possible. One fungus, the destructive Sclerotinia sclerotiorum, spews thousands of spores nearly simultaneously to form a plume that reduces drag to nearly zero and even creates...

Candida albicans, a fungus that kills more than 10,000 people with weakened immune systems each year, grows more dangerous as it forms and extends long strands of cells called hyphal filaments. In a paper published this month, UT Health Science Center San Antonio microbiologists describe a key factor involved in this damaging growth. This finding may eventually lead to targets for antifungal strategies, the scientists said. Patricia Carlisle, a Ph.D. student at the Health Science Center, and...

Two opportunistic pathogens that were once thought to be very different have evolved some sexual reproduction and disease-causing habits that are not only similar but also suggest that in the microbial world sex and virulence are closely linked, according to a review published this week in the online journal mBioâ“ž¢. "Although the mechanisms used by bacterial and fungal species to promote genetic exchange are distinct, recent studies have uncovered surprising...

Scientists today described development and successful initial tests on a substance that acts as a sunscreen for the microscopic spores of a fungus, brightening prospects for wider use of the fungus as a means of wiping out insect pests that attack food crops. "Our finding is especially important for the environment because improving the effectiveness of biological control treatments like this will help to reduce dependence on chemical pesticides," said team leader Robert W. Behle, Ph.D. Behle...

Scientists at the University of East Anglia, have shown that fungus-farming ants are using multiple antibiotics as weed killers to maintain their fungus gardens.Research led by Dr Matt Hutchings and published today in the journal BMC Biology  shows that ants use the antibiotics to inhibit the growth of unwanted fungi and bacteria in their fungus cultures which they use to feed their larvae and queen.These antibiotics are produced by actinomycete bacteria that live on the ants in a mutual...

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...

  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
