Tracking Movement Of Sugar In Plants
2014-04-09 12:22:18

By Karen McNulty Walsh, Brookhaven National Laboratory A new study published in the Proceedings of the National Academy of Sciences by scientists at the University of Queensland, Australia, overturns a long-held theory in plant science. Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory who are co-authors on this paper conducted critical radiotracer studies that support the new theory that plant sugars play a dominant role in regulating branching at...

Photos And Lab Analysis Needed For Leaf Study
2014-01-23 15:27:34

Brown University Automated remote photography is a convenient, labor-saving research tool for tracking leaf function and doing forest research. But does photography mirror what's actually happening on the ground? A new study finds photography accurately tracks the timing of red pigments in the fall, but the timing of green in the spring and summer — not so much. Every picture tells a story, but the story digital photos tell about how forests respond to climate change could be...

UCLA Biologists Uncover The Secrets Involved In Leaf Size, Shape
2013-10-31 14:36:02

Alan McStravick for redOrbit.com - Your Universe Online Trees, and more specifically, the leaves that adorn them, having predated human's foray into scientific learning, should harbor no mysteries at this point. However, nature continues to surprise us. Whether it is news of gold in eucalyptus leaves, as we learned last week with news out of Australia, or the simple yet profound truth of the math that governs internal leaf structure, human understanding continues to expand with the...

Genetic And Hormonal Signals Responsible For Shape, Function Of Leaves
2013-05-01 09:48:37

Brett Smith for redOrbit.com - Your Universe Online As the spring flowers (finally) begin to bloom across the United States, take a closer look and you may find a whole host of genetic and hormonal signaling that is responsible for the shape and function of various aspects of the leaves of plants. In the latest edition of the open access journal PLoS Biology, a group of UK biologists has detailed new insights into the differences and similarities between flowering plants´ petal and...

How Some Leaves Get Fat: It's In Their Veins
2013-04-11 15:35:43

Brown University A "garden variety" leaf is a broad, flat structure, but if the garden happens to be somewhere arid, it probably includes succulent plants with plump leaves full of precious water. Fat leaves did not emerge in the plant world easily. A new Brown University study published in Current Biology reports that to sustain efficient photosynthesis, they required the evolution of a fundamental remodeling of leaf vein structure: the addition of a third dimension. Leaves, after all,...

Using Kidney Bean Leaves As A Roach Motel For Bedbugs
2013-04-10 07:25:00

Lawrence LeBlond for redOrbit.com - Your Universe Online Bedbug infestations have been on the rise in recent years, and a remedy of yore may just be the answer to controlling a large problem from such a little pest, especially since the critters are becoming increasingly resilient against pesticide control. Researchers from the University of California, Irvine and the University of Kentucky (UKY) have rediscovered a type of plant that can be used as a bedbug trap, effectively stopping...

Trichomes Save Insect From Beetle Predation
2013-02-06 13:07:00

University of Guam Everyone needs to eat. But it's a dog-eat-dog world, and with the exception of the top predators, everyone also gets eaten. To cope with this vicious reality, a tiny insect that eats plants has learned to employ the plant's hairs for physical protection from its beetle predator. The pest is called the cycad aulacaspis scale, and its invasion into numerous countries in recent years has caused immeasurable loss of biodiversity. Cycads belong to an ancient lineage of...
