The George C. and Sue W. Sumner Molecular and Structural Laboratory is a 1700-square-foot research facility. It allows BRIT scientists, postdoctoral researchers, graduate students, visiting scientists, technical staff, and interns to investigate botany at various levels in a state-of-the art facility. The Sumner Lab is divided into five components: separate DNA and RNA extraction labs, a post-PCR molecular space, a structural space for comparative anatomy, and a scanning electron microscopy (SEM) room. The Sumner Lab is also home to the BRIT Biorepository, a GGBN-partnered biodiversity biobank dedicated to the long-term preservation and storage of DNA and tissues intended for genomic research. Research at the laboratory complements traditional field, herbarium, and literature research about plants and lichens.
