Society for Experimental Biology Growing plants in a microscope is helping scientists to view roots developing in 3D and in real time. "With the growth conditions under our control, we can explore how roots respond to different environmental conditions", says Professor Ernst Stelzer (Goethe Universität Frankfurt am Main, Germany). "This could help plant breeders to select crops which are more resistant to drought or flooding." Scientists already know that lateral roots in plants...

Water Provides Blueprints For Root Architecture
2014-06-10 03:00:34

Carnegie Institution Soil is a microscopic maze of nooks and crannies that hosts a wide array of life. Plants explore this environment by developing a complex branched network of roots that tap into scarce resources such as water and nutrients. How roots sense which regions of soil contain water and what effect this moisture has on the architecture of the root system has been unclear. New research from a team led by Carnegie's José Dinneny focuses on how physical properties of a root's...

SAN RAFAEL, Calif., April 4, 2014 /PRNewswire-USNewswire/ -- Roots of Peace, an international humanitarian NGO working to transform former minefields into thriving farmland, today celebrates the five millionth tree it has helped plant in various war-torn areas of the world. http://photos.prnewswire.com/prnvar/20140404/DC98881 The fifth( )millionth tree was a black pepper seedling planted on a farm in the Quang Tri region of Vietnam. As part of its International Day of Mine...

How Does A South American Tree Adapt To Volcanic Soils?
2014-01-24 15:50:12

American Journal of Botany Low soil nitrogen, not soil phosphorus levels, stimulate cluster root adaptation in the Proteaceae, Embothrium coccineum, a tree that may be key to reforestation in Patagonia Soils of southern South America, including Patagonia, have endured a high frequency of disturbances from volcanic eruptions, earthquakes, landslides, and erosion. In addition, massive fires in the mid-20th century were set to forests in the region in an effort to promote colonization. In...

Mushrooms Associated To Earthworms Can Develop Mechanism Of Environmental Engineering
2014-01-13 12:25:49

Technical University of Madrid This model, which was developed by a research group of the School of Forestry at the Technical University of Madrid (UPM), has shown how some types of mushrooms (such as truffles, boletus or chanterelles) associated to earthworms can develop a mechanism of environmental engineering. The use of this model can increase the levels of calcium and salts among tree roots what can result in an increase in mycorrhizas and to enhance the development of forests. This...

How Plants In Arid Lands Gain Nutrients To Survive
2013-11-06 11:48:07

Marine Biological Laboratory The vast sagebrush landscapes of the western United States are one of the largest ecosystems in North America.  Long, cold winters and hot, dry summers characterize these cold desert ecosystems and create bone-dry soils during seasonal droughts. New research published this week from MBL (Marine Biological Laboratory) senior scientist Zoe Cardon, John Stark (Utah State University), and their two former students, sheds light on how desert plants gain nutrients...

Recent study illustrates the usefulness of a new index for understanding lateral root initiation; shows nitric oxide can both promote and inhibit lateral root formation The structure and plasticity of root systems play an important role in determining the growth and yield of crop plants, and understanding how environmental and biological factors affect root structure is of key importance for plant scientists—particularly agricultural scientists. Lateral roots, as the name implies, are...

Microbial organisms associated with plant roots have far-flung global influences, from plant genetics to ecosystem health We often ignore what we cannot see, and yet organisms below the soil's surface play a vital role in plant functions and ecosystem well-being. These microbes can influence a plant's genetic structure, its health, and its interactions with other plants. A new series of articles in a Special Section in the American Journal of Botany on Rhizosphere Interactions: The Root...

Plants with thinner roots can grow deeper, a trait which could be exploited in lands affected by drought and nutrient deprivation. New research, to be presented at the Society for Experimental Biology meeting on July 5, shows that maize roots which have fewer cortical cells in the outer layer of their roots are more efficient at accessing water and nutrients. A research team headed by Prof Jonathan Lynch at the Pennsylvania State University, United States, found that maize roots show...
