Nigel Taylor, PhD
Associate Member and Dorothy J. King Distinguished Investigator
Donald Danforth Plant Science CenterBiofortification,Cassava,crop improvement,Disease Resistance
When he was finishing up his PhD in Plant Biotechnology at the University of Bath, he became aware of a multi-institutional project on cassava. “Cassava is an incredibly important crop for people in the developing world, but like many people in the industrialized North, I wasn’t that familiar with it.” Cassava was considered recalcitrant—it was difficult to work with and improve. Even though it was a major staple crop, it was only barely domesticated. And because it was so difficult, it was largely ignored, a so-called orphan crop. “Only a handful of labs were working on it, and then I made a breakthrough with cassava tissue culture transformation. Suddenly, we could work on it more easily, and I received a Rockefeller grant to go to Scripps [Research Institute] where I met Roger Beachy.” When Beachy came to St. Louis to be the first president of the Danforth Center, Nigel came with him. Today, the Taylor laboratory is part of VIRCA Plus, a multi-institutional project working to improve resistance to viruses that cause cassava brown streak disease (CBSD) and to increase levels of iron and zinc in the storage roots, the edible part of the plant. VIRCA Plus collaborates with research scientists, regulatory experts and communication specialists with the National Agricultural Research Systems (NARS) in Kenya, Uganda, Nigeria and Rwanda.
Growth Modelling,Phenomics,rhizosphere,X-ray imaging
The Topp laboratory deploys X-ray-based imaging and analysis of corn and other root systems to develop more robust and sustainable crops. While at the University of Georgia pursuing a genetics degree, Chris began studying plant pathogens. Interested in cutting-edge and emerging technologies, he worked as a research tech in an NSF-funded plant science lab to develop artificial chromosomes, an example of early synthetic biology. In grad school, he focused on maize, realizing that this crop could have the biggest impact: “In the U.S., there are about 90 million acres of corn planted each year. At an average density of 30,000 plants per acre, that’s 2.7 trillion corn plants. It’s been said there are more corn seeds are planted each year than stars in the Milky Way.” After launching his professional career at Duke University, Chris is today a principal investigator at the Danforth Center working to unlock the secrets of the hidden half of plants. When Chris learned about specialized 3D X-ray computed tomography (X-ray CT) systems for very large objects used in the aerospace industry, he saw a new potential application. In 2016, a partnership with Valent BioSciences, along with funding from the National Science Foundation, brought one of these 8-ton machines to the Danforth Center. The success of this instrument soon led to a smaller, but more powerful X-ray microscope to look at root-microbial interactions. Now the Topp lab can see the 3D subterranean world of roots nondestructively, at least for plants growing in large containers. The Topp lab’s X-ray CT and microscope facility for plant science at the Danforth Center is unique in the world.

Kris is the Sally and Derick Driemeyer Director of Education Research and Outreach at the Danforth Center, working to bring high-quality science education to more people and to inspire the next generation of scientists. Her research program focuses on both K-12 education and Undergraduate+ education through student engagement in content, participation in authentic science practice and improvement in science communication. An important part of the Danforth Center’s mission is to inspire the next generation of scientists to help feed the world and save the planet. “Plants form the foundation of life on Earth. When the general public lacks understanding of plants, that threatens the wellbeing of us all.” Kris and her team bring cutting-edge STEM education to students throughout the St. Louis region and beyond. She explains: “The research we’re doing is to determine how to educate the most number of people the most effectively. In doing so, we want to make education accessible to everyone worldwide.” Kris cites the Internet and mobile devices as the greatest technological advances in the field of education. “Mobile devices allow knowledge to be at the fingertips of people worldwide. Even in fairly remote areas without a lot of electricity. Having information at your fingertips, education is no longer about memorizing facts, but about how knowledge is applied creatively in new and novel ways.”
Allison Miller, PhD
Member; Professor of Biology, Saint Louis University
Donald Danforth Plant Science CenterAgro-Ecosystem Sustainability
The Miller Lab has zeroed in on long-lived crops as one possible tool to build a sustainable agricultural system. Long-lived crops, or perennials, live for many years, enriching the soil, and their deep roots combat erosion and sequester more carbon. In a world where 70% of crops are annuals, conversion of even a fraction to perennial crops would have a big environmental impact. “For years, humans have grown crops to serve human needs, often at the expense of the environment. It’s time we developed crops that can benefit the planet, as well as humans.” Allison and her team are currently trialing 12 herbaceous perennial species as candidates for crop development. It takes a long time to domesticate plants, and for longer-lived plants, it takes even longer. To speed the process, the Miller Lab is attempting early stage selection—predicting future traits from early life stage traits—an endeavor that she credits to Danforth Center resources. “The Danforth Center has incredible infrastructure. We have the computational power and know-how, unique robotic trait monitoring, the world’s best research greenhouses, expert staff, all under one roof. It makes cutting-edge research possible.” Today, as a principal investigator at the Danforth Center and professor of biology at Saint Louis University, Allison is still fascinated by the diversity of plants. She sees in them hope and potential to save the world: “Plants offer unlimited potential solutions to every major agricultural and ecological problem we are facing. We are not tapped out—we are not even close to discovering all the plant biodiversity that might help.”
Todd Mockler, PhD
Geraldine and Robert Virgil Distinguished Investigator, Member
Donald Danforth Plant Science Centercrop improvement,Genomics and Data Science
Todd is the Geraldine and Robert Virgil Distinguished Investigator at the Danforth Center and cofounder of Benson Hill. He is renowned as one of the pioneers who helped marry big data to plant science. The Mockler Lab is working at the forefront of sorghum research, but that focus developed almost through chance. Todd was working mostly in model plants in 2012, when he was invited to attend a sorghum conference as an external observer. “Sorghum has this amazing crop with innate drought and heat tolerance—I realized I wanted to work with it.” Today, 80 percent of the Mockler Lab’s work is sorghum-focused, both for food and biofuel. The work he’s most proud of so far is the TERRA-REF project. Plant breeding is currently limited by the speed at which phenotypes can be measured and how efficiently actionable biological information can be extracted from these measurements. The TERRA-REF field scanner is an outdoor phenotyping system in Maricopa, AZ, equipped with sensors to monitor crops growing in field conditions. The data collected and analyzed in the project is being used to accelerate sorghum breeding. “In 4 years, we went from an empty field to operating the world’s largest agricultural robot,” says Todd. The project includes more than 50 researchers, 14 different entities, has sequenced 400 sorghum genomes and established a data science infrastructure and knowledge base. As the initial project winds down, that infrastructure remains, and Danforth Center colleague Andrea Eveland, Ph.D., among others, have new projects that will continue to use it.
Computational Biology,Computer Vision,Genomics,Machine Learning
Like many scientists, invested teachers became powerful mentors in Noah’s life, and helped define his career. As an undergraduate student, he started working in the lab of Dr. Jim Carrington at Oregon State University. “Before I started working in the lab, I hadn’t thought about working with plants. I became really interested in the research they were doing in the Carrington Lab, so I decided to go to graduate school and work in the lab as a PhD student,” explains Noah. At the same time, Noah began pursuing a career in plant science, a new technology was emerging in the scientific community: high-throughput DNA sequencing. “We went from sequencing a few hundred DNA molecules at a time to doing millions at a time.” A year into grad school, the lab was collecting so much data that he began learning how to program and do data analysis with a computer. “I shifted pretty hard away from lab work at that point.” He hasn’t looked back since. Today, Noah leads the Data Science Facility. His team builds computational tools that help other scientists solve big data problems. These custom tools could be anything from an algorithm, to a program, to the infrastructure that houses a particular suite of software tools. “A lot of times in science, you can’t just ask a question and use a tool that comes out of the box,” says Noah. As a result, he has made it his team’s mission to be a collaborative hub at the Danforth Center that creates tools that help bridge different areas of expertise.
data science,Evolution,Genomics
Sona’s lab is interested in understanding how plants sense changes in their environment, like light, temperature, humidity and even microbes. As humans, we can sense that it is too cold outside and walk indoors where it is more comfortable. Plants don’t have that ability, so they have to modify what they are going to do within the environment. “The question my lab is asking is how are plants sensing a change in their surroundings and then what are some of the first changes that take place to respond?” To do this, Sona’s lab specifically looks at the proteins involved in sensing environmental changes, called G proteins. Her lab studies the signaling mechanisms of G proteins , and how that ultimately affects plant growth and development. As our environment changes and the population continues to grow, Sona’s work is becoming even more critical to feeding the world. In order to understand how a plant responds to changing environmental conditions like high temperatures, drought, or low nutrient availability, we need to know what is happening within the plant. Once we understand that, then we can improve the plants to be able to respond better to stress. In the future, this could mean that we may be able to grow crops in conditions that were previously uninhabitable. Not only could Sona’s research help plants respond to stress, it could also result in improved yield under normal conditions. “Our goal will always be to make plants survive better with lower inputs and under stressful conditions, while still maintaining or improving yield,” explains Sona.
