Researchers from Michigan State University have shed light on the biological puzzle of how plants launch immune responses. Reporting in Nature Communications, the team revealed one protein that plays a key role in mobilizing a plant’s antimicrobial defenses.

Michigan State University plant biologists have made a discovery that could help turn a natural kill switch in plant cells into a “life switch” that helps crops better survive the challenges presented by climate change. At its core, though, this is a fundamental finding, shared in the journal Nature Plants, that has implications across biology for how organisms respond to stress linked to overproduction of proteins by the cell.

Understanding the intricate puzzle pieces that make up the photosynthetic systems of plants can help researchers better understand how to grow and create plants that can survive in changing climate conditions. Naveen Sharma, a postdoctoral researcher in the Federica Brandizzi lab at the MSU-DOE Plant Research Laboratory (PRL), is one of the few people in the PRL who studies carbonic anhydrases (CAs)—proteins found in the chloroplast stroma where photosynthesis takes place. A study led by Sharma to better characterize CAs in the model plant Arabidopsis thaliana, was recently published in The Plant Journal.

The U.S. Department of Energy has awarded the MSU-DOE Plant Research Laboratory (PRL) a $12 million Department of Energy  Office of Basic Energy Sciences competitive renewal grant to continue research in photosynthetic energy capture, conversion and storage. The three-year grant (2023-2026) will allow PRL scientists to continue in their mission to understand how photosynthetic organisms function and thrive in natural environments, and enable the development of new technologies that improve human lives.

MSU biochemist Robert Quinn has spent years studying the biochemistry of coral bleaching, a heat-induced response to stress causing it to turn white. Bleaching is damaging to reefs and is expected to increase due to climate change. While Quinn has discovered unique betaine lipids in coral that are markers of resistance to coral bleaching, very little is known about them. During a literature review of these lipids, Quinn discovered that MSU colleague, Christoph Benning, had written on the subject. This connection led to the two scientists teaming up on a $1.9 million NSF grant to study the role that betaine lipids play in coral bleaching.

Yongsig Kim, a senior research associate in the Michigan State Universit-Department of Energy Plant Research Laboratory, is leading MSU’s $1.2 million grant from the U.S. Department of Agriculture’s Sustainable Agricultural Systems program in the National Institute of Food and Agriculture explore what controlled enviornment agriculture will look like in a low-carbon world and new vegetation that leaves a low-carbon footprint. 

The statistics are familiar. The world’s population is expected to increase by nearly 50 percent in the next century, while the demand for agriculture crops is expected to more than double by 2050. The extreme weather anomalies caused by climate change are expected to continue and worsen in the future, which could substantially reduce agricultural production globally. Michigan State University’s renowned plant researchers are collaborating on solutions to grow more abundant, nutritious and resilient plants that will feed a growing population.

The moon holds answers, and Michigan State University plant biologist Federica Brandizzi and her team are bringing those answers within reach. Patience, creativity and a cheerful fearlessness are turning insights buried in plant seeds into pathways to the very survival of the human race. 

Michigan State University researchers have solved a puzzle that could help switchgrass realize its full potential as a low-cost, sustainable biofuel crop and curb our dependence on fossil fuels. Berkley Walker’s team in the Department of Plant Biology in MSU’s College of Natural Science has revealed why switchgrass stops performing photosynthesis in the middle of the summer — its growing season — limiting how much biofuel it yields. This knowledge, published in the journal Frontiers in Plant Science, is a key piece to overcoming this quirk and getting the most out of switchgrass.

A new study from plant scientists at Michigan State University demonstrates that there’s a link between climate change and nutrition. The research, led by MSU’s Berkley Walker and his team shows that, although elevated levels of carbon dioxide can be good for photosynthesis, increasing CO2 levels can tinker with other metabolic processes in plants. And these lesser-known processes could have implications for other functions like protein production. Their findings were recently published in Nature Plants.
