Philosophical Transactions of the Royal Society, Series B 374: 20170403. Specimen-based analysis of morphology and the environment in ecologically dominant grasses: the power of the herbarium. A dynamic co-expression map of early inflorescence development in Setaria viridis provides a resource for gene discovery and comparative genomics.
Inflorescence abscission zones in grasses: diversity and genetic regulation. The Setaria viridis genome and diversity panel enables discovery of a novel domestication gene. Divergent gene expression networks underlie morphological diversity of abscission zone development in grasses (Poaceae). Plastome phylogenomics of sugarcane and relatives confirms the segregation of the genus Tripidium (Poaceae-Andropogoneae). Tansley Insight: Getting closer: vein density in C4 leaves.

Kellogg, Sterile Spikelets Contribute to Yield in Sorghum and Related Grasses, The Jenkins, Yunqing Yu, Doug K.Īllen, Elizabeth A. Taylor AuBuchon-Elder, Viktoriya Coneva, David M. By combining genomics, population genetics, and computational biology, DNA variants, genes, mechanisms, and pathways critical for performance and tolerance to heat and drought will be identified. The sampling will focus on Andropogoneae, a tribe of grass that are among the most productive and water efficient plants, but for which breeding has taken advantage of variation in only a few species such as maize, sorghum, and sugarcane. This project proposes to use nearly a thousand species, collectively representing over a billion years of evolutionary history, to understand the rules of convergence and constraint in the genomes with an aim to model fitness under drought and temperature stress. However, to design crops to be adapted to a wider range of environments will require more knowledge on the genetic variation that produces phenotypic variation and adaptation. Increases in crop productivity will be crucial if we are to feed a growing world population and expanding adaptation of crops to a diverse range of environments would help immensely. Our research in the Kellogg Lab, along with that of the Center’s many talented scientists, contributes to a bigger picture: increase our understanding of the underlying mechanisms of plants, so we can make more resilient crops, and protect and enhance one of Earth’s most precious resources – food. Another mission of the Center is to “preserve and renew the environment.” By studying cereal crops and their relatives in the grass family, we can then predict how wild species may adapt to a warmer, drier climate. In our lab, we study how these wild plants grow, make seeds, and adapt to drought and floods.
These crops were selected by humans from an entire ecosystem of wild grasses, which dominate more than 25% of the land area of the earth. Cereal crops in the grass family - including rice, maize (corn), wheat, sorghum, barley, and oats - have fed civilizations for millennia, and are the center of our research. We believe that food security is a human right, and that plant scientists have an obligation to contribute to feeding the growing global population. This is the central mission of the Center. “Feed the hungry and improve human health” Louis region as a world center for plant science.” This is one part of the Center’s mission to “enhance the St. Like the other labs in the Center, we are an employer, a small business that keeps the economic engine of the city running. As you can see in the descriptions of projects below, the lab is a small business supported by grant funding, much of which represents federal tax dollars brought home to Missouri.
