The Kellogg Lab
Our Research
Welcome to the Kellogg Lab, with homes at the Donald Danforth Plant Science Center and the Arnold Arboretum of Harvard University. 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. Like the other labs in the Center, we are an employer, a small business that keeps the economic engine of the city running. This is one part of the Center’s mission to “enhance the St. Louis region as a world center for plant science.”
“Feed the hungry and improve human health”
This is the central mission of the Center. We believe that food security is a human right, and that plant scientists have an obligation to contribute to feeding the growing global population. 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. 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. In our lab, we study how these wild plants grow, make seeds, and adapt to drought and floods. 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.
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.

COLLABORATIVE RESEARCH: Evolution of genetic networks in grass abscission zones
Agriculture depends on plants that hold on to their seeds until harvest, yet wild plants need to drop their seeds in a process known as shattering or abscission. People have selected for spontaneous mutant plants that do not shatter, leading to domesticated crops such as wheat, rice, and corn. In a world facing rapid population growth and changing climates, we need to understand how shattering occurs to domesticate and improve new wild or less domesticated cereal crops, thereby diversifying food choices and improving agriculture in marginal environments. This project examines the shattering process, which is controlled by a specialized set of cells known as an abscission zone (AZ). Cell development and cell wall structure of the AZ is compared in foxtail millet, pearl millet, tef and fonio and their wild relatives. We have identified two genes that are required for a functional AZ in most species. We have mutated these genes in four species to determine exactly how they cause morphological differences in the AZ. We have involved high school students, undergraduates and secondary school teachers in conducting the research, and the secondary school teachers have used their experiences to develop new lesson plans, and further impact next generation education in science.
This project is a collaboration with the lab of Andrew Doust at Oklahoma State University (https://www.doustlab.com/).

Integration and modularity in grass diversification
We now have a trove data sequence on Andropogoneae, which has permitted generation of a species-level phylogeny incorporating sequences from about 40% of the 1200 species in the tribe. We have captured morphmetric data on the spikelets of a larger set of species, as well as downloading environmental data. This is permitting phylogenetic analyses of morphological evolution and its correlation with the environment.

Verdant
Verdant provides an easy-to-use environment for visualization, annotation, manipulation, alignment, and phylogenomic analysis of whole chloroplast genomes. Verdant is hosted by CyVerse and is built on a growing database of chloroplast genomes.
Includes a user friendly step-by-step tutorial

Fast-Plast
Fast-Plast is a pipeline that leverages existing and novel programs to quickly assemble, orient, and verify whole chloroplast genome sequences. For most datasets with sufficient data, Fast-Plast is able to produce a full-length de novo chloroplast genome assembly in approximately 30 minutes with no user mediation.
Currently, Fast-Plast is written to accomodate Illumina data, though most data types could be used with a few changes.
Fast-Plast uses a de novo assembly approach by combining the de bruijn graph-based method of SPAdes with an iterative seed-based assembly implemented in afin to close gaps of contigs with low coverage. The pipeline then identifies regions from the quadripartite structure of the chloroplast genome, assigns identity, and orders them according to standard convention. A coverage analysis is then conducted to assess the quality of the final assembly.
Primaclade
Primaclade is a web-based application that accepts a multiple species nucleotide alignment file as input and identifies a set of PCR primers that will bind across the alignment. The Primaclade program iteratively runs the Primer3 application for each alignment sequence and collates the results. The user may adjust a number of parameters to improve and refine the results. These options include: 1) the maximum number of degenerate base pairs allowed, 2) the number of gapped lines in the alignment to ignore, 3) a region of the alignment to exclude for primer discovery, 4) the primer melting temperature and 5) the approximate GC content of the primer. Primaclade creates an HTML results page that recaps the original alignment, provides a consensus sequence and lists primers for each alignment area. In addition, the generated primers are color-coded to reflect the level of degeneracy in the primer.
