Hormone clue to root growth

Plant roots provide the crops we eat with water, nutrients and anchorage. Understanding how roots grow and how hormones control that growth is crucial to improving crop yields, which will be necessary to address food security and produce better biofuels. Now an international group of scientist...

Getting to the root of science in a nutty way

COLLEGE STATION - Dr. Leo Lombardini has gone underground to get the most top secret information in his field. Lombardini is watching roots grow in his experimental orchards, and it is sort of nuts - he's a pecan researcher. His study is part of a national specialty crop research project fun...

Origin of root offshoots revealed

Ghent, Belgium VIB researchers at Ghent University have discovered the substance that governs the formation of root offshoots in plants, and how it works.

US Air Force technology helps scientists understand plant root function

MADISON, WI SEPTEMBER 8, 2008-- The McClellan Nuclear Radiation Center (MNRC) in Sacramento, CA was developed by the U.S. Air Force to detect corrosion and defects in aircraft structure using an imaging technique called neutron radiography. This technique is currently helping soil scientists under...

Getting to the root of the matter

Madison, WI, August 18, 2008 -- Like most things that exist underground, plant roots are out-of-sight and easily forgotten, but while flowers, leaves, and other aboveground plant parts are more familiar, plant roots are equally deserving of our appreciation. Beneath every towering tree, tasty crop...

Tel Aviv University researchers root out new and efficient crop plants

A part of the global food crisis is the inefficiency of current irrigation methods. More irrigated water evaporates than reaches the roots of crops, amounting to an enormous waste of water and energy. Tel Aviv University researchers, however, are investigating a new solution that turns the prob...

Evolution of root nodule symbiosis with nitrogen-fixing bacteria

Dartmouth researchers find the root of the evolutionary emergence of vertebrates

HANOVER, N.H. Dartmouth College researchers and colleagues from the University of Bristol in the U.K. have traced the beginnings of complex life, i.e. vertebrates, to microRNA. The researchers argue that the evolution of microRNAs, which regulate gene expression, are behind the origin of early ve...

At the root of nutrient limitation, ecosystems are not as different as they seem

TEMPE, Ariz. -- Anyone who has thrown a backyard barbecue knows that hot dogs are inexplicably packaged in different numbers than buns eight hot dogs per pack versus 10 hot dog buns. Put in ecological terms, this means that weenie roasts are hot-dog limited the extra buns are worthless without h...

Salk scientists get to the root of plant cell fate

When Robert Burns compared his love to a red, red rose, he definitely wasn't referring to a topless mutant. That's because rather than being topped by a lovely, fragrant bloom, a rose mutant in the gene known as TOPLESS would be crowned by a homely second root. Researchers at the Salk Institute f...

Through such researchers' work, it will undoubtedly contribute to improving crops that humans arou...

Researchers find gene that may be at root of potato blight

Researchers have found a gene they suspect plays an important role in triggering the blight that wiped out Ireland's potato crops a century-and-a-half ago. And the pathogen that contains this gene still causes massive amounts of agricultural damage throughout the modern world?on the order of bil...
