Some trees growing in nutrient-poor forest soil may get what they need by cultivating specific root microbes to create compounds they require. These microbes are exceptionally efficient at turning inorganic minerals into nutrients that the trees can use.

"President Obama called it 'the worst environmental disaster America has ever faced.' So I thought I should face it and head to the Gulf"—these are the opening words on the popular blog Guilty Planet as the author, marine biologist Jennifer Jacquet, embarked on a ten day trip to Louisiana. As a scientist, Jacquet was, of course, interested in the impact of the some four million barrels of oil on the Gulf's already depleted ecosystem, however she was as equally keen to see how Louisianans were coping with the fossil fuel-disaster that devastated their most vital natural resource just four years after Hurricane Katrina.

Scientists have developed a new tool for deciphering the genetics of a native prairie grass being widely studied for its potential as a biofuel. The genetic map of switchgrass is expected to speed up the search for genes that will make the perennial plant a more viable source of bioenergy.

Researchers in Portugal and the U.S. studied the introgression -- the movement of a gene from one species into the gene pool of another -- of rye alien chromatin in the wheat genome, and showed that genomes behave like social entities.

A new article reveals for the first time that microscopic marine algae known as phytoplankton have been declining globally over the 20th century. Phytoplankton forms the basis of the marine food chain and sustains diverse assemblages of species ranging from tiny zooplankton to large marine mammals, seabirds, and fish.

Tiny marine algae, known as phytoplankton, are the backbone of the marine food chain, yet a new study in Nature has found that this backbone is disintegrating. Researchers discovered that since 1950 phytoplankton has declined by approximately 40 percent across the Northern Hemisphere, a decline that corresponds to warming waters due to climate change. Given that phytoplankton feed the oceans' abundance all the way up the food chain—from zooplankton to fish to seabird to sharks to humans—the decline has likely impacted the very structure of the ocean.

Shade-grown coffee farms support native bees that help maintain the health of some of the world's most biodiverse tropical regions, according to a new study.

Could a "hot" flower attract pollinators by serving as a reward in a plant-pollinator mutualism? Many flowering plants produce nectar and pollen as rewards in exchange for pollination services by insects and other animals. Interestingly, however, a few plants have flowers that also produce heat metabolically -- so what is the adaptive function of this flower heating?

Researchers have shown that even the most widely-varying species of plants share remarkable similarities in the composition of proteins in them that undergo phosphorylation, a regulatory mechanism involved in various cellular phenomena. A database released by the group, with information on over three thousand phosphorylated proteins and phosphorylation sites in rice, opens new doors in the study and engineering of plants.

Genetic analysis of giant pandas has shown that features of their landscape have a profound effect on the movement of genes within their population. Researchers found that physical barriers, such as areas lacking bamboo plants and other forest foliage, can separate giant pandas into isolated genetic groups.

An agricultural scientist may have found a way to cut the amount of ammonia produced by cattle, using a key ingredient of the brewer's art: hops.

With a little cross-breeding and some determination, plant physiologist and forage agronomist Dr. Dariusz Malinowski is trying to add more colors to the world of hibiscuses. Malinowski is working on breeding winter-hardy hibiscus in what started as a hobby about four years ago, but in the last year has been added to the strategic plan of the Vernon research program.

A research team has discovered a fundamental entry mechanism that allows dangerous fungal microbes to infect plants and cause disease. The discovery paves the way for the development of new intervention strategies to protect plant, and even some animal cells, from deadly fungal infections.

Citrus growers, beware. Florida winters are getting more extreme, causing plants to flower later and potentially shrinking the growing seasons for some of the state's most vital crops.

Recently, academic debate has been swirling around the existence of unusual quantum mechanical effects in the most ubiquitous of phenomena, including photosynthesis, the process by which organisms convert light into chemical energy. In a new paper, these ideas are put to the test.

Grains, vegetables and fruit taste delicious and are important sources of energy. However, humans cannot digest the main component of plants - the cellulose in the cell wall. Even in ruminants, animals that can metabolize cellulose, the digestibility of the cell wall plays a crucial role in feed utilization. Scientists are therefore looking for ways of increasing the digestibility of animal feed, and of utilizing plant cell walls to generate energy. To do this they must first understand how plant cells develop their cell walls from cellulose and identify the genes and proteins involved. Scientists have now discovered a hitherto unknown protein required for cellulose production.

Participants of the ongoing international biodiversity meeting have learned from local Balinese that local traditions can play a significant role in maintaining natural biodiversity.

The digestibility of the cell wall plays a crucial role in feed utilisation. Scientists are therefore looking for ways of increasing the digestibility of animal feed, and of utilising plant cell walls to generate energy.

Yesterday the U.S. Department of Commerce announced a $4.6 million U.S. Economic Development Administration (EDA) grant for the expansion of the Danforth facility. The money will be used to build a new greenhouse and a pre-incubation feeder facility.

By imaging the cell walls of a zinnia leaf down to the nanometer scale, energy researchers have a better idea about how to turn plants into biofuels. In a paper appearing online in the journal Plant Physiology, a team from Lawrence Livermore led by Michael Thelen has used four different imaging techniques to systematically drill down deep into the cells of Zinnia elegans.
