UC San Diego Biologists at UC San Diego have solved a long-standing mystery concerning the way plants reduce the numbers of their breathing pores in response to rising carbon dioxide levels in the atmosphere. In a paper published in this week’s early online edition of Nature, they report the discovery of a new genetic pathway in plants, made up of four genes from three different gene families that control the density of breathing pores—or “stomata”—in plant leaves in response...

Society for Experimental Biology Scientists have identified a new mutant plant that accumulates excessive amounts of starch, which could help to boost crop yields and increase the productivity of plants grown for biofuels. Researchers from the Max Planck Institute of Molecular Plant Physiology looked for excessive starch accumulators in the model plant Arabidopsis thaliana that had been mutated using Agrobacterium tumefaciens. In one of the mutant plants, the starch granules were...

Plants Respond To Leaf Vibrations Caused By Chewing Caterpillars

[ Watch The Video: Plants Respond To Leaf Vibrations Caused By Insects’ Chewing ] University of Missouri-Columbia Previous studies have suggested that plant growth can be influenced by sound and that plants respond to wind and touch. Now, researchers at the University of Missouri, in a collaboration that brings together audio and chemical analysis, have determined that plants respond to the sounds that caterpillars make when eating plants and that the plants respond with more...

Surprising Spread Of Spring Leaf-out Times: Study
2014-06-19 03:54:51

Richard Primack, Boston University Medical Center Observing 1,600 species at 8 botanical gardens globally should impact climate-change models Despite conventional wisdom among gardeners, foresters and botanists that woody plants all "leaf out" at about the same time each spring, a new study organized by a Boston University biologist found a surprisingly wide span of as much as three months in leaf-out times. Significantly, observations the past two springs of 1,597 woody plants in...

Michigan Tech Winter takes its toll on living things. To protect themselves from the elements, bears hibernate, and trees go dormant.   Biologists have observed what happens when trees become dormant, but up to now, they haven’t understood the underlying genetic mechanisms that enable them to start growing again. A team led by molecular geneticists from Michigan Technological University has identified and characterized a gene that tells a poplar tree when winter ends and a spring...

PARMAX™ Professional Series Hybrid LED Pro Panels excel in two critical lighting fundamentals for plants. First, intensity, the more intensity (quantity) of light the better your plants will grow and the second being, spectrum, as light intensity increases, light spectrum becomes more important. (PRWEB) June 03, 2014 PARMAX™ Professional Series Hybrid LED Pro Panels grow lights made by Smart Grow Technologies are much more energy efficient than standard HID (High Intensity Discharge)...

MPG Flea beetles outwit their host plant’s mustard oil bomb and use it for their own purposes Almost all herbivorous insects are specialized to feed on specific host plants and have adapted to their chemical defenses. Flea beetles are important pests of cabbage and other cruciferous plants, such as mustard, horseradish and rapeseed. These plants use a sophisticated defense system, known as the mustard oil bomb, to get rid of their enemies : If plant tissues are wounded, glucosinolates...

Hydro Dynamics, Inc. has launched a new portal related to cavitation based applications in the chemical industry along with a new secondary logo based upon the periodic table. Rome, GA (PRWEB) May 06, 2014 Hydro Dynamics, Inc. (HDI) is launching a new chemistry portal and secondary logo related to its work in the chemical industry...

How Does Your Garden Glow?

By Laurie J. Schmidt, NASA's Jet Propulsion Laboratory Science is full of serendipity -- moments when discoveries happen by chance or accident while researchers are looking for something else. For example, penicillin was identified when a blue-green mold grew on a Petri dish that had been left open by mistake. Now, satellite instruments have given climate researchers at NASA and other research institutions an unexpected global view from space of a nearly invisible fluorescent glow that...

Aquatic Algae Can See A Wide Spectrum Of Light
2014-05-02 03:00:50

[ Watch The Video: Algae “See” A Wide Spectrum Of Light ] Andy Fell, UC Davis Aquatic algae can sense an unexpectedly wide range of color, allowing them to sense and adapt to changing light conditions in lakes and oceans. The study by researchers at UC Davis was published earlier this year in the journal Proceedings of the National Academy of Sciences. Phytochromes are the eyes of a plant, allowing it to detect changes in the color, intensity, and quality of light so that the...

Bittercress (Barbarea vulgaris), also commonly known as Herb Barbara, Rocketcress, Yellow Rocketcress, Winter Rocket, and Wound Rocket, is a European biennial herb. This plant displays a rosette of shiny, dark green leaves at the base and additional pinnately divided leaves on the stem. In the spring, yellow flowers originate in tightly packed terminal groups just above the foliage. Bittercress grows wildly as a weed in many parts of North America. The flowers can be in bloom May...

The Par Rubber Tree (Hevea brasiliensis), is a tree belonging to the family Euphorbiaceae. It is the most economically important member of the genus Hevea. It is of major economic importance because its sap-like extract (latex) can be collected and is the primary source of natural rubber. The Pará rubber tree initially grew only in the Amazon Rainforest. Now most rubber tree plantations are in southeast Asia and tropical Africa. Attempts to cultivate the tree in other areas in South...
