Research Interests:

The Loopstra lab is interested in the molecular genetics of loblolly pine, particularly adaptation to drought and climate change. Loblolly pine is commercially the most important pine in the United States and is also a model system for gymnosperms. We are currently involved in two large USDA National Institute of Food and Agriculture (NIFA) projects. The PineRefSeq (Pine Reference Sequences) project ( is sequencing the genomes and transcriptomes of loblolly pine and sugar pine, the two largest genomes sequenced to date. The Loopstra lab has been involved in the collection and treatment of tissues for the transcriptomes and is involved in the data analyses. PINEMAP (Pine Integrated Network: Education, Mitigation, and Adaptation project) ( integrates research, extension, and education to enable southern pine landowners to manage forests to increase carbon sequestration; increase efficiency of nitrogen and other fertilizer inputs; and adapt forest management approaches to increase forest resilience and sustainability under variable climates. The Loopstra lab is using exome capture to obtain DNA for SNP (single nucleotide polymorphism) discovery and genotyping in a population of 384 trees from though out the native range. We will look for associations with phenotypic characteristics important for adaptation and productivity as well as with climatic variables.
