New clues for using common fungus to promote crop growth and health
Trichoderma species — a common fungus found in soils — have varying abilities to promote tomato plant growth and differentially affect the abundance of certain soil bacteria, according to a study led by researchers at Penn State. The work was the latest in a line of research evaluating the use of this common group of fungi as an alternative to pesticides for controlling soilborne pathogens, said Seogchan Kang, professor in the College of Agricultural Sciences and co-corresponding author of the study.

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.

Low-cost sensor system could warn farmers of salt stress in plants
Soil salinity is a critical concern in agriculture when excessive soluble salts restrict a plant’s water uptake, according to the U.S. Department of Agriculture, hindering crop growth and reducing yields on roughly 30% of U.S. irrigated land. Caused by irrigation, poor drainage or saltwater intrusion, soil salinity impacts soil structure, reduces fertility and causes economic losses. To help growers identify and mitigate salt stress, in a proof-of-concept study, a team led by Penn State researchers built a low-cost sensor system that detects signals released by plants in trouble.

The 'Spirit of Chocolate' celebrates chocolate as both science and story
On Valentine’s Day, the Palmer Museum of Art became a tasting room and a classroom all at once. “The Art of Chocolate: A Guided Tasting Experience,” presented by the Arboretum at Penn State, invited guests to explore chocolate as both science and story, pairing research with sensory discovery and chocolate with cheese. The event was a collaboration among arboretum staff and College of Agricultural Sciences professors Siela Maximova and Mark Guiltinan, co‑leaders of Penn State’s Cacao and Chocolate Research Network.

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.
