The grand challenge of the 21st century is to sustain 10 billion people in a degraded global environment. A central element of that effort will be the development of climate-resilient agroecosystems that can provide food, fiber, and fuel at a reduced environmental cost. Water limitation is the single greatest limit to plant growth and this will worsen in the future because of global climate change. Low soil fertility is a primary barrier to food security in developing nations and in rich nations intensive fertilization is a primary cause of environmental pollution. A better understanding of root function and root health, including root associations with symbionts, will open avenues to create new resilient crops and agroecosystems, and improved management of natural ecosystems, that are urgently needed.

Researchers identify a gene that regulates the angle of root growth in corn
The discovery of a gene that regulates the angle of root growth in corn is a new tool to enable the breeding of deeper-rooting crops with enhanced ability to take up nitrogen, according to an international team of researchers, led by Penn State.
Newly discovered trait helps plants grow deeper roots in dry, compacted soils
A previously unknown root trait allows some cereal plants to grow deeper roots capable of punching through dry, hard, compacted soils, according to Penn State researchers, who suggest that harnessing the inherited characteristic could lead to crops better able to deal with a changing climate.

Cover crop roots are key to understanding ecosystem services
To judge the overall effectiveness of cover crops and choose those offering the most ecosystem services, agricultural scientists must consider the plants’ roots as well as above-ground biomass, according to Penn State researchers who tested the characteristics of cover crop roots in three monocultures and one mixture.
