We have molecular and genetic projects to investigate cold stress tolerance mechanisms and flowering time regulation in the model plants Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa). We are currently focusing on exploring the natural variation that exists in rice to map new quantitative trait loci (QTLs) for various cold tolerance traits and to identify QTL associated genes. Toward this goal, we are using a sophisticated method to screen the US Department of Agriculture rice mini-core (RMC) collection and the Rice Diversity Panel 1 (RDP1), both of which represent the diversity and complexity of the world’s germplasms. Our preliminary results are consistent with the hypothesis that mechanisms of cold stress tolerance responses measured in various ways are under complex genetic control. Our long-term goals are to field-test our laboratory results, to introgress large-effect QTLs into elite rice lines, to fine-map interesting QTLs, and to validate cold tolerance candidate genes associated with them. In parallel we are exploring the natural variation of Arabidopsis to study specific aspects of stress tolerance and flowering time regulation, specifically focusing on hybrid proline and glycine-rich protein (HyP/GRP) and FRIGIDA-LIKE(FRL) genes.
In addition to these research projects, we are translating research outcomes into “real world” applications by cultivating cold tolerant rice varieties on (currently) one acre of land in the cold climate of Wisconsin.
