Connected habitats help wildlife fight disease, strengthen protective microbes

A team led by Penn State biologists found that amphibians in connected natural forests and aquatic habitats were more likely to host beneficial skin microbes that inhibit a deadly fungal pathogen. But when these habitats become spatially separated due to planted crops, infrastructure development or other human land use, those microbial defenses weaken and pathogen infection levels can increase with potentially deadly results.

Plant scientists receive $1.96M NIH grant to study plant-bacteria partnerships

A team of plant scientists in Penn State’s College of Agricultural Sciences has received a $1.96 million, five-year grant from the National Institutes of Health (NIH) to fund a study of how beneficial plant-bacteria partnerships evolve, persist, and can be harnessed to improve health and agriculture. This grant, called a Maximizing Investigator’s Research Award, supports a lab's long-term research vision rather than an individual project.

Simple vineyard growing practice impacts soil microbiome deep below surface

In an effort to produce more and better grapes at a lower cost and with less environmental impact, vineyard growers have increasingly planted grass between rows of vines. These "groundcovers" root shallowly, but can benefit vineyard soils and reduce the need for herbicide applications. Now, a team of plant scientists in Penn State’s College of Agricultural Sciences has found that implementing this practice impacts far more than previously thought. It not only alters the biology and ecology at the surface, where the grasses are planted, but also alters the system far below the surface, the researchers reported in a new study published in Phytobiomes Journal.

Q&A: How can microbiome science solve problems in agriculture?

Decades of research has shown promise for using microbiome science to solve several problems facing agriculture, but these findings have not yet been translated to practical recommendations for growers, according to a team of scientists in Penn State’s College of Agricultural Sciences.

Helping soil microbes kill weed seeds to aid organic farmers

To better equip organic farmers to control weeds, a team of Penn State agricultural scientists received a four-year, $935,000 grant from the U.S. Department of Agriculture to study how promoting soil microbes to infect and kill weed seeds might reduce problematic weed species.

Domestication has changed the chemicals squash flowers use to attract bees

In a new study published in the Journal of Chemical Ecology, a team led by researchers in Penn State’s College of Agricultural Sciences found that domesticated flowers have different scent chemical profiles than wild plants in several species of squash. Additionally, the specialized pollinators of these plants—squash bees—detect different compounds, called floral volatile organic compounds (VOCs) in wild plants that they co-evolved with than in domesticated plants.
