My research activities are centered on genomic aspects of plant biology and plant pathogens. My research primarily involves projects focused on high throughput sequencing, functional genomics, comparative genomics, and bioinformatics.
Rice Genomics and Bioinformatics
Worldwide, rice is one of the world’s most important crop plants with 50% of the population dependent on rice as a food source. Furthermore, rice is a member of the grass family (Poaceae) and is considered a model species for the cereals as it has a near-complete finished genome and a wealth of resources for functional genomics studies. One important component of a genome sequence is accurate, uniform annotation of genes, gene models, and gene function. Using a suite of automated, semi-automated, and manual computational methods, my group has annotated the rice genome (http://rice.plantbiology.msu.edu/). Working with researchers at the National Institute of Agrobiological Sciences (Tsukuba, Japan) and D. Schwartz (University of Wisconsin), we recently incorporated next generation sequencing (NGS) data from the reference accession (Nipponbare) as well data from the optical map to correct sequencing errors and misassemblies in the underlying IRGSP sequence. Using these refined reference pseudomolecules, we have revised our annotation to include new transcript and protein evidence, orthologous groups, community annotation, and new data-mining tools. Release of version 7 of our annotation is now available at http://rice.plantbiology.msu.edu/.
As with other genomes, a large percentage of genes in the rice genome have no known function, remaining an enigma even eight years after completion of the rice genome. While correlative in nature, transcriptome expression patterns are informative with respect to deducing function as they can reveal associations with a biological process. Using publicly available rice gene expression data, we have performed gene correlation analyses to identify sets of genes that are functionally co-regulated. Using the WGCNA correlation network analysis protocol, we have identified modules of highly inter-connected genes within larger networks (Childs et al. 2011). Examination of these modules reveals that these sets of genes have functional annotations that are consistent with the tissues/treatments in which they are expressed. From fifteen expression datasets, we have identified 87 gene modules involving a total of 14,521 unique genes. A total of 3,547 genes assigned to gene modules had no prior functional annotation (20% of all rice genes with no known function), and these genes can now be annotated as being members of defined gene modules.
The Poaceae inhabit a wide range of environmental niches and possess a number of unique morphological, physiological, and developmental processes of agricultural relevance including floral/fruit development, drought tolerance, and C4 photosynthesis. This divergence occurred in the last 55-70 million years and it is intriguing how these traits evolved. In collaboration with Dr. Ning Jiang (MSU Horticulture Department), we used genomic sequences from 184 plant species to identify 861 rice genes termed “Conserved Poaceae Specific Genes” (CPSGs) that are conserved within the Poaceae family yet lack significant sequence similarity to non-Poaceae species.As measured through several gene metrics, the CPSGs are distinct from evolutionary conserved genes and transposable elements and the majority of CPSGs encode proteins with no known function (Campbell et al. 2007). We are using a two pronged approach to define the function of the CPSGs. First, we have performed expression profiling using a floral and seed developmental series from four Poaceae species (rice, maize, sorghum, and Brachypodium distachon) to identify orthologous genes expressed in parallel reproductive tissues in all four species (Davidson et al. 2011, 2012). Second, we are determining the function of a subset of our co-expressed orthologous CPSGs using mutant, knockout, knockdown, and/or over-expression studies in rice followed by phenotyping using a standardized set of metrics for floral/seed development and yield.
One intriguing feature of plant genomes is the high density of transposable elements, the so-called “jumping genes” initially discovered by Barbara McClintock in the 1940’s. One class of transposable elements, the Pack-MULEs, has the potential to create new genes in a genome. In collaboration with Dr. Ning Jiang, MSU Horticulture Department, we are determining the potential for Pack-MULEs to create new genes in the rice genome through their transposition activity. This involves sequencing additional rice cultivars and exploring epigenetic and expression features of Pack-MULEs that indicate they may function as bona fide genes.

Potato Genomics and Bioinformatics
Potato is grown for its tuber, a below-ground storage organ that is not only calorie rich but also high in vitamins. Potato is the third most important crop on a worldwide basis and is the most significant non-grain crop species. More importantly, potato acreage in developing countries is increasing due to its wide adaptability, yield, and nutrition. My group was instrumental in generation of the potato genome sequence released in 2011 (Potato Genome Sequencing Consortium, 2011). In addition, we analyzed the potato transcriptome throughout development, abiotic stress, biotic stress and hormone treatment (Massa et al. 2011). Using the potato genome sequence, along with transcriptome sequences from cultivated potato accessions, we identified single nucleotide polymorphisms (SNPs) in cultivated potato (Hamilton et al. 2011) and developed a 8303 SNP array to genotype cultivated potato (Felcher et al. 2012) and implement genomics-guided breeding approaches for potato. We recently completed an analysis of diversity in cultivated potato in which we were able to assess historic potato breeding efforts in the last 150 years and the differentiation of market classes (chip processing, frozen French fry processing, yellow fleshed, pigmented, etc) through targeted breeding efforts.
Cultivated potato is a vegetatively propagated autotetraploid with a highly heterozygous genome, unique among other major crop and model plant species. With funding from the National Science Foundation, we are examining the role of heterozygosity, copy number variation, presence/absence variation, epigenetic features, and allele specific expression in vigor in potato. This project, in collaboration with scientists at MSU, Virginia Tech, and University of Wisconsin, will provide information on genomic features in a polyploidy that correspond with agronomic phenotypes.

Biofuel Feedstock Genomics
One source of renewable energy is the conversion of plant-based biomass (or feedstocks) into biofuels such as ethanol. A number of biofuel feedstock research programs are focused on improving biomass production in grass species such as maize (corn) and switchgrass. This is due to the potential for energy conversion of plant-derived biomass, established agricultural production methods for maize and switchgrass, and high biomass yields. My group has developed the Biofuel Feedstock Genomics Resource which provides a web-based portal or “clearing house” for genome sequence and annotation data, germplasm data, and large-scale functional genomic datasets for plant species relevant to biofuel feedstock production.
In collaboration with Drs. Shawn Kaeppler, Natalia de Leon, and Mike Casler at the University of Wisconsin as part of the Great Lakes Bioenergy Research Center (http://glbrc.org), a research collaboration between MSU and University of Wisconsin, we are identifying natural variants in maize and switchgrass to target for improved biomass production and recalcitrance in these two species. Our work to date has included development of a maize gene atlas (Sekhorn et al. 2010), characterization of genotypic diversity in maize (Hansey et al. 2012), analysis of switchgrass transcriptome diversity, and development of an exon capture array for switchgrass. On-going efforts are focused on genotyping thousands of maize and switchgrass accessions for use in association mapping. These collaborative efforts, in which genomics and bioinformatics are coupled with breeding efforts, will enhance the efficiency and success in breeding crop species for biofuel feedstock use and contributing to the increased use of renewable energy sources.
