Plant molecular geneticists discover, and begin to crack, the epigenetic code

When plants sense environmental challenges such as drought or extended periods of extreme temperatures, they instinctively reprogram their genetic material to survive and even thrive.

Jared Ali named director of the Penn State Center for Chemical Ecology

Jared Ali, Dorothy Foehr Huck and J. Lloyd Huck Chair of Chemical Ecology and associate professor of entomology in the College of Agricultural Sciences, has been named director of the Penn State Center for Chemical Ecology (CCE).

Jared Ali named Huck Chair of Chemical Ecology

Jared Ali, associate professor of entomology in Penn State's College of Agricultural Sciences, has been named the Dorothy Foehr Huck and J. Lloyd Huck Chair of Chemical Ecology by the University’s Huck Institutes of the Life Sciences.

Climate-associated genetic switches found in plants

Genetic variants that can act as switches directing structural changes in the RNA molecules that code for proteins in plants have been experimentally validated in plants for the first time. The changes to RNA structure can affect the molecule’s stability, how it interacts with other molecules, and how efficiently it can be translated into protein — all of which can impact its function and the traits of the plant.

Internet-based precision irrigation system shows promise for fresh-market tomato

An “internet of things” — or IoT — system monitoring real-time data from soil-based sensors to activate an automated precision irrigation setup can conserve water and boost crop production, according to a team of Penn State researchers.

New plant science team gets grants from USDA-NIFA for research on soil microbes

An assistant professor in Penn State’s College of Agricultural Sciences has received $950,000 in two competitive grants from the U.S. Department of Agriculture to lead a team studying interactions between plants and rhizobial soil bacteria, with the long-term goal of boosting forage and crop production while reducing environmental impacts of fertilizer use.

How grasses like wheat can grow in the cold

A new, large-scale analysis of the relationships among members of the largest subfamily of grasses, which includes wheat and barley, reveals gene-duplication events that contributed to the adaptation of the plants to cooler temperatures.

A new molecular family tree of grasses

The evolutionary relationships among grasses — including important crop plants like wheat, rice, corn, and sugarcane — have been clarified in a new molecular study of the grass family tree. Having a clear picture of the relationships among the grasses can help understanding of how important crop traits like seed size or disease resistance evolves and eventually could inform manipulation of these traits to increase crop yields.

Penn State biologist Michael Axtell named distinguished professor

Michael Axtell, professor of biology at Penn State, has been selected to receive the title of distinguished professor of biology in recognition of his exceptional record of teaching, research, and service to the University community.

Geneticists close to grasping how plant communities may adapt to climate change

A century after scientists first noted that the environment contributes to the evolution of adaptive differences among plant populations, scientists are on the verge of figuring out how that adaptation happens — by combining results from huge “common garden” experiments with genomic sequencing.
