Climate change opens new avenue for spread of invasive plants
Plants that range northward because of climate change may be better at defending themselves against local enemies than native plants.   view more (2008-11-20)

Regulations for health-promoting gentech food products
Newly published report lists regulations for health-promoting gentech food products Differences between EU and US clarified A new report has been published listing the regulations for food crops and medicinal plants that contain extra health-promoting ingredients as a result of genetic modification... view more (2001-12-12)

Plants tell caterpillars when it's safe to forage
The world is filled with cues that could influence the daily feeding patterns of an organism. Many plants, for example, respond to foraging damage by releasing specialized chemical signals-volatile organic compounds that evaporate in the air-that attract the forager's natural enemies.   view more (2006-05-16)

Alarm pheromone causes aphids to sprout wings
Chemical communication within insect species is often much more sophisticated than expected. When aphids are attacked by predators such as ladybird beetles, they release an alarm pheromone, (E)-ß-farnesene, that has long been known to cause other aphids to walk around or drop from the plant.   view more (2005-05-18)

Multi-million-dollar Smith Institute To Be Dedicated At Hebrew University Agriculture Faculty
The multi-million-dollar Robert H. Smith Institute of Plant Sciences and Genetics in Agriculture will be dedicated on Tuesday, Oct. 21, at the Hebrew University Faculty of Agricultural, Food and Environmental Quality Sciences in Rehovot. The dedication includes the inauguration of two new... view more (2003-10-20)

How size matters
The beauty of nature is partly due to the uniformity of leaf and flower size in individual plants, and scientists have discovered how plants arrive at these aesthetic proportions.   view more (2007-12-13)

When Plants Think Alike
Biologists have discovered that a fundamental building block in the cells of flowering plants evolved independently, yet almost identically, on a separate branch of the evolutionary tree--in an ancient plant group called lycophytes that originated at least 420 million years ago.    view more (2008-05-28)

Predators: an overlooked player in plant-pollinator relationships
Biologists have long recognized that predators can help to shape ecological communities -- wolves promote the growth of young trees through predation on moose, otters keep kelp forests thriving by preying on sea urchins, etc. Yet we have seldom considered the consequences of predation on animals... view more (2003-08-13)

Organic nitrogen gives new clue to biodiversity
Scientists have found that organic nitrogen is more important for plant growth than previously thought and could contribute to maintaining diversity in grasslands.   view more (2006-04-12)

Annuals converted into perennials
Annual crops grow, blossom and die within one year. Perennials overwinter and grow again the following year. The life strategy of many annuals consists of rapid growth following germination and rapid transition to flower and seed formation, thus preventing the loss of energy needed to create... view more (2008-11-10)

Why do insects like to eat some plants more than others?
In a study appearing in the forthcoming issue of The American Naturalist, Tom E. X. Miller, Andrew J. Tyre, and Svata M. Louda (all of the University of Nebraska, Lincoln) examined herbivore dynamics, specifically why plants aren't all eaten at the same rate.   view more (2006-11-14)

Plants uptake antibiotics
Scientists at the University of Minnesota have been evaluating the impact of antibiotic feeding in livestock production on the environment.   view more (2007-07-12)

Plants Can Protect Themselves From Aphids And Locusts
Moscow biologists have proved that people can use the capability of some plants to protect themselves from vermin insects with the help of biologically active substances. It has been found that plants can protect themselves from vermin insects. One way is to use substances which the plants... view more (2003-12-15)

Deep in the ocean, a clam that acts like a plant
How does life survive in the black depths of the ocean? At the surface, sunlight allows green plants to "fix" carbon from the air to build their bodies.   view more (2007-02-21)

Green corridors lead nowhere
Green corridors, which have become a common feature of urban planning and conservation over the past decade, may make very little difference to the diversity of plants found in our towns and cities, ecologists have found. Speaking at the British Ecological Society’s Winter Meeting, to be held... view more (2001-12-10)

Scientists discover genetic key to growing hardier, more productive plants
A team of scientists led by University of Connecticut plant biologist Roberto Gaxiola has discovered an overlooked genetic key to generating plants that are more productive, more drought resistant and can grow in soils low in nutrients.   view more (2005-10-07)

UWE scientists find link between wilting plants and impotence
Researchers studying plant behaviour have discovered similarities between the processes preventing plants from wilting and humans from suffering impotence. Data recently published by the University of the West of England shows the same chemical chain of events is involved in both situations - and... view more (2002-02-21)

Higher carbon dioxide, lack of nitrogen limit plant growth
Earth's plant life will not be able to "store" excess carbon from rising atmospheric carbon dioxide levels as well as scientists once thought because plants likely cannot get enough nutrients, such as nitrogen, when there are higher levels of carbon dioxide   view more (2006-04-13)

Will global warming increase plant frost damage?
Widespread damage to plants from a sudden freeze that occurred across the Eastern United States from 5 April to 9 April 2007 was made worse because it had been preceded by two weeks of unusual warmth, according to an analysis published in the March 2008 issue of BioScience.   view more (2008-03-03)

A biological technique could save up to 2 million euros at sewage treatment plants
A new method for treating the smell of rotten eggs emitted by sewage plants, developed in conjunction by a researcher at the Universitat Autònoma de Barcelona's Engineering School (ETSE) and a researcher from the University of California, could lead to worldwide savings of two million euros... view more (2003-07-15)

Desert plant may hold key to surviving food shortage
The plant, Kalanchoe fedtschenkoi, is unique because, unlike normal plants, it captures most of its carbon dioxide at night when the air is cooler and more humid, making it 10 times more water-efficient than major crops such as wheat. Scientists will use the latest next-generation DNA sequencing to... view more (2008-06-20)

Tropical plants go with the flow ... of nitrogen
Tropical plants are able to adapt to environmental change by extracting nitrogen from a variety of sources, according to a new study that appears in the May 7 early online edition of The Proceedings of the National Academy of Sciences.   view more (2007-05-08)

UBC researchers reveal dwarf aquatic plants' hidden ancestry
A team of UBC researchers has re-classified an ancient line of aquatic plants previously thought to be related to grasses and rushes. The discovery clarifies what may be one of the biggest misunderstandings in botanical history.   view more (2007-03-15)

South Pacific plant may be missing link in evolution of flowering plants
A new University of Colorado at Boulder study involving a "living fossil plant" that has survived on Earth for 130 million years suggests its novel reproductive structure may be a "missing link" between flowering plants and their ancestors.   view more (2006-05-18)

"Facts needed, not just opinions": Risk assessment research initiated to determine effects of genetically modified plants on soil ecosystems
Do genetically modified plants present a risk to the environment? "Most of the arguments used both in support and against the use of genetically modified crops to date have not been based upon facts, but rather emotion," claims George Kowalchuk of the Netherlands Institute of Ecology... view more (2001-06-11)
