Plants are very sensitive to light conditions because light is their source of energy and also a signal that activates the special photoreceptors that regulate growth, metabolism, and physiological development. Scientists believe that these light signals control plant growth and development by activating or inhibiting plant hormones. New research from Carnegie plant biologists has altered the prevailing theory on how light signals and hormones interact. Their findings could have implications...

The researchers decided to embark on this study in order to find out which mechanisms are used by plants when they extract water from very dry or somewhat inhospitable land. "In the case of mangrove swamps, for example, the plants are able to extract freshwater from a saltwater environment, despite the fact that the osmotic pressure should make quite the opposite happen", explains Professor Jos© Luis P©rez Díaz, who studies this type of relatively unknown...

Nonindigenous insects and pathogens, including many that cause serious damage, have established in forests in the United States with regularity over 15 decades Nonindigenous insects and pathogens continue to become established in US forests with regularity despite regulations intended to prevent this, according to a study published in the December 2010 issue of BioScience. The study, by a team led by Juliann E. Aukema of the National Center for Ecological Analysis and Synthesis in Santa...

(Ivanhoe Newswire) "“ Children with autism are much more likely to have deficits in their ability to produce cellular energy than typically developing children. The researchers found that cumulative damage and oxidative stress in mitochondria, the energy producer of the cell, could influence the onset and severity of autism, suggesting a strong link between autism and mitochondrial defects. The authors believe that lack of ability to fuel the brain neurons might lead to some of the...

By Shelley Littin, NASA Space Grant intern, University of Arizona New University of Arizona research indicates that leaf vein patterns correlate with functions such as carbon intake and water use "“ knowledge that could help scientists better understand the complex carbon cycle that is at the heart of global climate warming. "Leaves have very different networks of veins. They have different shapes, different sizes, different thicknesses," said Benjamin Blonder, a doctoral student in the...

According to a popular hypothesis, grasses such as maize, sugar cane, millet and sorghum got their evolutionary start as a result of a steep drop in atmospheric carbon dioxide levels during the Oligocene epoch, more than 23 million years ago. A new study overturns that hypothesis, presenting the first geological evidence that the ancestors of these and other C4 grasses emerged millions of years earlier than previously established. The findings are published in the journal Geology. C4 plants...

Innovative research technique reveals C4 grasses older than previously thought A new analysis of fossilized grass-pollen grains deposited on ancient European lake and sea bottoms 16-35 million years ago reveals that C4 grasses evolved earlier than previously thought. This new evidence casts doubt on the widely-held belief that the rise of this incredibly productive group of plants was driven by a large drop in atmospheric carbon dioxide concentrations during the Oligocene epoch. The...

Photosynthesis is arguably the most impressive feat of nature, where plants harvest light energy and convert it into the building blocks of life at fantastically high efficiency. Indeed modern civilization became possible only with the cultivation of plants for food, shelter and clothing. While scientists have been able to discover details of the fascinating process by which plants store solar energy as chemical energy, how developing plants build and regulate their solar reactors is still...

A popular cancer drug could be produced cheaply and sustainably using stem cells derived from trees, a study suggests A popular cancer drug could be produced cheaply and sustainably using stem cells derived from trees, a study suggests. Researchers have isolated and grown stem cells from a yew tree whose bark is a natural source of the anticancer compound paclitaxel. The development could enable the compound to be produced on a commercial scale at low cost, with no harmful by-products....

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...
