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.
