Scientists at the Donald Danforth Plant Science Center have made several scientific discoveries demonstrating the significant roles Heterotrimeric G proteins play in plant development and yield. Sona Pandey, Ph.D., principal investigator at the Danforth Plant Science Center and her collaborators have published several papers on their research in recent months. Pandey and collaborators showed that “G proteins” occur in a wide range of land plants and algae. This discovery was published...

The overuse of nitrogen fertilizers in agriculture can wreak havoc on waterways, health and the environment. An international team of scientists aims to lessen the reliance on these fertilizers by helping beans and similar plants boost their nitrogen production, even in areas with traditionally poor soil quality. Researchers from the Center of Plant Genomics and Biotechnology at the Technical University of Madrid (UPM) and the Advanced Photon Source (APS) at the U.S. Department of...

A 125-year debate on how nitrogen-fixing bacteria are able to breach the cell walls of legumes has been settled A 125-year debate on how nitrogen-fixing bacteria are able to breach the cell walls of legumes has been settled. A paper to be published on Monday by John Innes Centre scientists reports that plants themselves allow bacteria in. Once inside the right cells, these bacteria take nitrogen from the air and supply it to legumes in a form they can use, ammonia. Whether the bacteria...

The genome of Medicago, a close relative of alfalfa and a long-established model for the study of legume biology, has been sequenced by an international team of scientists, capturing around 94 per cent of its genes. The research gives new insights into the evolution of the Papilionoid subfamily of legumes, which includes peas, soybean and all legumes grown as crops. Plants in this family can house and work with bacteria to provide them with nitrogen from the air. The new findings...

Nitrogen is vital for all plant life, but increasingly the planet is paying a heavy price for the escalating use of nitrogen fertilizer. Excess nitrogen from fertilizer runoff into rivers and lakes causes algal blooms that create oxygen-depleted dead zones, such as the 6,000 to 7,000 square mile zone in the Gulf of Mexico, and nitrogen in the form of nitrous oxide is a potent greenhouse gas. But new findings by Stanford researchers that reveal the inner workings of nitrogen-producing bacteria...

Some soil microorganisms are capable of forging associations with plant roots in the form of symbioses. Certain of these relationships play a highly important ecological and agronomic role. Arbuscular mycorrhizal symbiosis (which links a plant to a fungus) thus gives plants a mechanism for improving their supply of water and mineral nutrition. This association has been in existence for 400 million years and appears to have accompanied plants in their colonization of the terrestrial...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
