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.

Huck Institutes announces recipients of nine interdisciplinary seed grants
Penn State’s Huck Institutes of the Life Sciences has awarded nine research teams seed funding for 2026-27. These grants support high-impact, innovative research projects that align with the Huck’s strategic research priorities and have the potential to drive scientific breakthroughs and generate significant return on investment.
Newly discovered corn trait may help improve crop drought tolerance
Some corn plants are genetically predisposed to develop longer, less constricted water-conducting tissues and deeper roots, which helps them deal with drought. That’s the conclusion of a team led by Penn State researchers that conducted a study of the plant’s xylem tissue that moves water upward from the roots out to the leaves. They found that corn plants with longer metaxylem vessel elements also tend to have rapidly elongating roots, deeper root systems, stronger water transport capacity, greater water capture and improved drought adaptation
Q&A: What can plant evolution teach people about breeding better crops?
May 22 is United Nations International Day for Biological Diversity, drawing attention to a critical resource for developing crops that are resilient or resistant to extreme weather and other threats to their health, according to Jesse Lasky, associate professor of biology at Penn State.

Plant genes influence bacterial evolution in legume-bacteria partnership
In a recently published study, Penn State researchers described the complex relationship between plant host genes and rhizobial genes, and how plant genes strongly influence which rhizobial strains plants chose from a diverse mixture.
