Resistant wheat goes for the gut to protect against Hessian flies
Resistant wheat plants stave off attacks by Hessian fly larvae by essentially destroying the fly's midgut and its ability to absorb nutrients, according to a study by Purdue University and the US Department of Agriculture.

Brown biologist solves mystery of tropical grasses' origin
Brown University biologist Erika Edwards and a colleague have found that rainfall, not temperature, was the primary trigger for the evolutionary beginnings of C4 tropical grasses. Their results are published in the Proceedings of the National Academy of Sciences.

Moss helps chart the conquest of land by plants
Clues to how the first land plants managed to avoid drying out might be provided by bryophytes, a group that includes the mosses, many of which retain remarkable drought tolerance. Some mosses can become so dry they crumble in the hand, but, if remoistened, will begin making proteins within minutes. Research published in the Jan. 29 issue of the journal Science, reveals several components of the signaling pathway that underlies the moss' Lazarus-like behavior.

ARS scientists turn to a wild oat to combat crown rust
Agricultural Research Service scientists are tapping into the DNA of a wild oat, considered by some to be a noxious weed, to see if it can help combat crown rust, the most damaging fungal disease of oats worldwide.

Invasive plants are beneficiaries of climate change in Thoreau's woods
Invasive plants could become even more prevalent and destructive as climate change continues, according to a new analysis of data stretching back more than 150 years. The Harvard University scientists who conducted the study say that non-native plants, and especially invasive species, appear to thrive during times of climate change because they're better able to adjust the timing of annual activities like flowering and fruiting.

Virus pulls bait and switch on insect vectors
A common plant virus lures aphids to infected plants by making the plants more attractive, but when the insects taste the plant, they quickly leave for tastier, healthier ones. In the process, the insects rapidly transmit the disease, according to Penn State entomologists.

Ecologists discover forests are growing faster
Speed is not a word typically associated with trees; they can take centuries to grow. However, a new study to be published the week of Feb. 1 in the Proceedings of the National Academy of Sciences has found evidence that forests in the Eastern United States are growing faster than they have in the past 225 years. The study offers a rare look at how an ecosystem is responding to climate change.

Gene function discovery: Guilt by association
Scientists have created a new computational model that can be used to predict gene function of uncharacterized plant genes with unprecedented speed and accuracy. The network, dubbed AraNet, has over 19,600 genes associated to each other by over 1 million links and can increase the discovery rate of new genes affiliated with a given trait tenfold. It is a huge boost to fundamental plant biology and agricultural research.

Are new genes always better?
Revegetation seems like a beneficial strategy for conserving and restoring damaged ecosystems, and using a variety of species can help increase biodiversity in these systems. But what risks are involved with introducing seeds from other locations to plants located near the damaged site? When new, foreign genes are introduced to a damaged site, neighboring populations may experience initial negative effects; however, over time, the negative effects may diminish and the maladapted foreign genes will decrease.

Better food makes high-latitude animals bigger
New research suggests that animals living at high latitudes grow better than their counterparts closer to the equator because higher-latitude vegetation is more nutritious. The study, published in the February issue of the American Naturalist, presents a novel explanation for Bergmann's Rule, the observation that animals tend to be bigger at higher latitudes.

The almond tree's secret weapon
Has the almond tree developed a unique way of drawing potential pollinators? A group of researchers at the department of environmental and evolutionary biology and the department of science education at the University of Haifa-Oranim speculate that the toxin called amygdalin that is found in almond tree nectar is in fact an evolutionary development intended to give that tree an advantage over others in its surroundings.

The roots of food security
Scientists at the Max Planck Institute for Developmental Biology in Tübingen, Germany, describe that the plant hormone auxin together with an increased cell cycle activity leads to a boost in root branching in the common thale cress Arabidopsis thaliana. In addition, they showed that two proteins that are crucial for embryo development also play a critical role in root branching. These results could be used to raise plants that are fast-growing even in dry and nutrient-poor soils.

Green energy management
Plants use energy derived from sunlight to form sugars from carbon dioxide and water by the process of photosynthesis. Recent discoveries made by a research group at Ludwig-Maximilians-Universitaet in Munich provide new insights into the control circuit that enables plants to make optimal use of incident light.

Natural pest control saves coffee berry
A predator for the devastating coffee berry borer has just been discovered in Africa. Dr. Juliana Jaramillo from the International Centre of Insect Physiology and Ecology in Kenya and Dr. Eric Chapman from the University of Kentucky have identified a previously unknown predatory thrips which feeds on the eggs and larvae of the coffee berry borer. Their study is published online in Springer's journal Naturwissenschaften -- The Science of Nature.
