Road maintenance may accidentally spread the seeds of invasice plants, according to Penn State researchers. "The road graders that are used during these operations can act like a plow, pushing seeds along the road," said Emily Rauschert, senior project associate and applied ecologist in crop and soil sciences. "They can pick up seeds of an invasive grass and spread them several orders of magnitude further than the natural dispersal." The researchers created a computer simulation based on...

The genetic 'wiring' that helps a seed to decide on the perfect time to germinate has been revealed by scientists for the first time. Plant biologists at The University of Nottingham have also discovered that the same mechanism that controls germination is responsible for another important decision in the life cycle of plants "” when to start flowering. Their discovery throws light on the genetic mechanisms that plants use to detect and respond to vital environmental cues and could be a...

WASHINGTON, Feb. 28, 2011 /PRNewswire/ -- Socially conscious shoppers are latching on to a new gardening trend this spring - and it's not only fashionable flowers or subliminal scents. Cutting-edge chains like Sloat Garden Centers in California, Calloway's and Cornelius Nursery in Texas, and Earl May Seed and Nursery in the Midwest are partnering with the Weed Out Hate Initiative to market Sunflower Peace Seeds. With the public increasingly attuned to violence on our own shores as well...

A Los Angeles photographer has developed a technique to create extremely detailed images of flowers. Using technology used by NASA on Mars, David Leaser's innovative Nightflowers collection shows large scale botanicals with such detail you can literally see the pollen glistening on the stamens. The images have attracted the attention of Architectural Digest, and they will be introduced at their 10th Anniversary Home Design Show on March 17 in New York City. Los Angeles, CA (PRWEB) February 8,...

When it comes to pollen formation, seed plants go for overproduction Plants producing flower pollen must not leave anything to chance. The model plant thale cress (Arabidopsis), for instance, uses three signaling pathways in concert with partially overlapping functions. The yield becomes the greatest when all three processes are active; however, two are sufficient to form an acceptable quantity of flower pollen. In a new study, Peter Huijser and his colleagues at the Max Planck Institute for...

Study yields new model that can help managers calculate when plants will burst bud under different climate scenariosThe opening of buds on Douglas-fir trees each spring is the result of a complex interplay between cold and warm temperatures during the winter, scientists with the U.S. Forest Service's Pacific Northwest Research Station have found.Their research"”which is featured in the December issue of Science Findings, a monthly publication of the station"”led to the development...

From southern Africa's pineapple lily to Western Australia's swamp bottlebrush, flowering plants are everywhere.  Also called angiosperms, they make up 90 percent of all land-based, plant life. New research published this week in the Proceedings of the National Academy of Sciences provides new insights into their genetic origin, an evolutionary innovation that quickly gave rise to many diverse flowering plants more than 130 million years ago. Moreover, a flower with genetic programming...

Two proteins involved in powdery mildew infection in plants also play an important role in fertilisation Mildew infections not only cause unsightly vegetable patches, they can also result in extensive crop failure. Interestingly, the processes involved in infections with this garden pest are similar to those involved in fertilisation. Scientists from the Max Planck Institute for Plant Breeding Research in Cologne and the University of Zurich have identified two proteins in the model plant...

The seeds that you plant in your backyard garden next spring "” and farmers sow in their fields "” may have a guardian angel that helps them sprout, stay healthy, and grow to yield bountiful harvests. It's a thin coating of chemicals termed a "seed treatment" that can encourage seeds to germinate earlier in the season, resist insects and diseases, and convey other advantages. These new seed defenders are the topic of an article in the current issue of Chemical & Engineering...

"How do hearts, wings or flowers get their shape?" asks Professor Enrico Coen from the John Innes Centre. " Unlike man-made things like mobile phones or cars, there is no external hand or machine guiding the formation of these biological structures; they grow into particular shapes of their own accord." "Looking at the complex, beautiful and finely tuned shapes produced by nature, people have often wondered how they came about. We are beginning to understand the basic genetic and chemical...

Iris is a genus of flowering plants with showy flowers ranging in color from gold, copper-red or yellow to white, blue, blue-violet, lavender, tan, maroon and purple. Pink and apricot colored irises have also been bred in some species. The name "Iris" can be applied to the genus or to any of the species within it. It is also applied to various subdivisions within the genus. Description There are many species of iris widely distributed throughout the northern temperate zone. Their...
