Why plants' soapy defences against disease don't always wash.
Natural soaps are an important weapon in the armoury that plants deploy to protect against disease attack, but a report today, in the international journal Nature, describes how disease-causing microbes can turn these plant defences to their own advantage. Scientists at the Sainsbury Laboratory (SL)[1] Norwich, UK, have discovered that fungi that... view more... (2002-08-19)
At the root of nutrient limitation, ecosystems are not as different as they seem
Anyone who has thrown a backyard barbecue knows that hot dogs are inexplicably packaged in different numbers than buns - eight hot dogs per pack versus 10 hot dog buns. Put in ecological terms, this means that weenie roasts are "hot-dog limited" - the extra buns are worthless without hot dogs to fill them. view more (2007-11-09)
Flowering plants speed post-surgery recovery
Contact with nature has long been suspected to increase positive feelings, reduce stress, and provide distraction from the pain associated with recovery from surgery. Now, research has confirmed the beneficial effects of plants and flowers for patients recovering from abdominal surgery. view more (2008-12-29)
Discovery about evolution of fungi has implications for humans, says U of M researcher
As early fungi made the evolutionary journey from water to land and branched off from animals, they shed tail-like flagella that propelled them through their aquatic environment and evolved a variety of new mechanisms (including explosive volleys and fragrances) to disperse their spores and reproduce in a terrestrial setting. view more (2006-10-23)
How plants manage calcium may reduce effects of acid rain
A new understanding of how plants manage their internal calcium levels could lead to modifying plants to avoid damage from acid rain. The pollutant disrupts calcium balance in plants by leaching significant amounts of the mineral from leaves as well as the agricultural and forest soils the plants live in. view more (2007-03-12)
Pesticides in the nation's streams and ground water
Today, the U.S. Geological Survey released a report describing the occurrence of pesticides in streams and ground water during 1992-2001. view more (2006-03-03)
New Method Confirms Importance of Fungi in Arctic Nitrogen Cycle
A new method to calculate the transfer of nitrogen from Arctic mushrooms to plants is shedding light on how fungi living symbiotically on plant roots transfer vital nutrients to their hosts. view more (2006-05-10)
The emerging scientific discipline of aeroecology
In the history of science and technology, there is an infrequent combination of empirical discoveries, theories and technology developments converge that make it possible to recognize a new discipline. view more (2008-08-04)
Air pollution damages plants
If you live in a large town or city, have you ever wondered why some plants do not grow well in your garden, despite your best efforts? It is, in part, because of air pollution. At a symposium on the biology of air pollution hosted by the Institute of Biology this week in London, delegates heard from experts about the effects of pollutants on... view more... (1999-10-27)
Outwitting pesky parasites
Across the southern United States, an invisible, yet deadly parasite known as the root-knot nematode is crippling soybean crops. view more (2007-07-16)
Same gene protects from 1 disease, opens door to another
Botanists at Oregon State University have discovered that a single plant gene can cause resistance to one disease at the same time it produces susceptibility to a different disease - the first time this unusual phenomenon has ever been observed in plants. view more (2007-08-29)
Urban water ecology at the ESA annual meeting
Increasingly, human urban development overlaps with habitat for wild animals and plants, creating environments that degrade natural landscapes. view more (2009-08-03)
Research into lost marine life helps Iran
Research at the University of Bradford is helping Iran's Government in a US$130m claim that the 1991 Gulf War damaged its fisheries industry. Iran is making the claim to the United Nations that oil, which spilled into Persian Gulf sea following the Iraqi invasion of Kuwait, has affected its fish stocks and marine life. The University's Department... view more... (2003-11-12)
DMSO raises a stink at sewage treatment plants
Researchers believe they've found the source of a stinking problem that has plagued areas surrounding sewage treatment plants for decades. view more (2005-12-21)
Genetic engineering of plants: nature was first
Queen Mary and Westfield College scientists studying resistance to infection in plants have discovered by chance that a natural form of genetic engineering has already brought foreign genes into their genetic make-up. view more (1998-09-01)
Scientists Discover What Plants Do During Long Winter Nights
In research published today scientists at the John Innes Centre (JIC), Norwich(1), report on what plants do during the hours of darkness. During daylight hours plants use the energy from sunlight to power the production of food (sugar) from carbon dioxide and water. This process (photosynthesis) is well understood, but what happens when the sun... view more... (2003-12-29)
Heterosis in populations in nature of a domesticated plant
Few studies quantify evolutionary processes in populations of domesticated plants in traditional farming systems. In February's Ecology Letters, Pujol, David and McKey show that these systems offer unusual opportunities for studying microevolution. view more (2005-02-08)
Subproducts resulting from disinfecting drinkable water
For his PhD thesis, Unai Iriarte Velasco analysed strategies for reducing levels of subproducts from the disinfection of drinkable water and their application in optimising the functioning of water treatment plants. view more (2005-09-09)
Study shows genetically engineered corn could affect aquatic ecosystems
A study by an Indiana University environmental science professor and several colleagues suggests a widely planted variety of genetically engineered corn has the potential to harm aquatic ecosystems. The study is being published online this week by the journal Proceedings of the National Academies of Sciences. view more (2007-10-09)
New crops needed for new climate
Global food security in a changing climate depends on the nutritional value and yield of staple food crops. Researchers at Monash University in Victoria, Australia have found an increase in toxic compounds, a decrease in protein content and a decreased yield in plants grown under high CO2 and drought conditions. view more (2009-06-29)
