College of Ag Sciences awards bridge funding for global research collaborations

Penn State’s College of Agricultural Sciences has awarded bridge funding to four faculty members to support research collaborations addressing soil fertility, public health, climate resilience and agricultural trade include two from the Center for Root and Rhizosphere Biology.

Researchers used advanced imaging techniques, conducted at Penn State’s publicly funded Core Facilities, to study the architecture of the Turnip Crinkle Virus (TCV). This plant pathogen has an icosahedral — or 20-sided — shell that is the same structure as many human pathogens, such as enteroviruses, noroviruses, poliovirus, hepatitis B virus and the virus that causes chickenpox.

Unique bond identified as key to viral infection speed

Viruses are typically described as tiny, perfectly geometric shells that pack genetic material with mathematical precision, but new research led by scientists at Penn State revealed a deliberate imbalance in their shape that helps them infect their hosts.

Two College of Ag Sciences faculty earn spots on highly cited researchers list

Francisco Dini-Andreote and Andrew Patterson in Penn State’s College of Agricultural Sciences are among the most highly cited researchers in 2025, according to the Clarivate Analytics Web of Science Group.

New test distinguishes vaccine-induced false positives from active HIV infection

A Penn State team has developed a new approach capable of differentiating active HIV infection from false positives — which could potentially accelerate vaccine development and testing.

Wild lupine genetics could be key to conservation of species

Researchers at Penn State studying declining populations of sundial lupines in the eastern part of the United States are closer to determining how the plant's genetics could be used to inform reseeding strategies to help with conservation efforts of the blue flowering plant.

College of Ag Sciences research tour explores connection between food, health

Government and industry stakeholders got a literal taste of the future of agriculture by sampling hydroponically grown greens at one of several presentations during the Penn State College of Agricultural Sciences’ annual Legislative Research Tour, held Sept. 25 at the University Park campus.

The team found that a number of populations of Xanthomonas and Pseudomonas bacteria were present on the plants that had developed a resistance against bacterial speck, suggesting they play a role in suppressing the disease. Credit: Dan Gol/Unsplash. All Rights Reserved.

New clues in how plant microbiomes protect against bacterial speck disease

Bacterial speck is a common disease affecting tomatoes that can result in lower yields for growers. A new study led by researchers at Penn State gives new clues on how a plant’s microbiome can be used to combat the pathogen.

Gene editing, traditional crossbreeding produce disease-resistant cacao plants

Novel approach could revolutionize sustainable chocolate production while addressing global food security, researchers report.

If beekeepers use organic management practices over time, they even can produce 50% more honey than when following conventional management practices, according to the researchers. Credit: Simon Kadula/Unsplash. All Rights Reserved.

Organic beekeeping can be even more profitable than conventional methods

Organic beekeeping can support healthy and productive honey bee colonies, and a new study led by researchers in Penn State’s College of Agricultural Sciences found that adopting organic honey bee colony management is not only profitable, but in some cases, it can be even more profitable than conventional management.
