Conservation Genomics: New tools to address species recovery

Genomics has revolutionized the field of conservation genetics. In recent years, the cost of sequencing thousands of loci from a single individual has dramatically dropped, making genomic tools more accessible for projects, even those with limited budgets. Genomic tools such as RADseq and target capture allow us to subsample the genome to allow for sequencing of greater numbers of individuals. At the Atlanta Botanical Garden, we are applying modern genomic tools to address recovery of several species of conservation concern. We have developed novel methods such as target capture bait sets for orchids (Orchidaceae963) and Torreya taxifolia which have allowed for rapid population genetic studies of species with large and complex genomes. Target capture additionally allows us to sequence the same set of loci reliably in all samples, allowing us to combine and reuse datasets to address novel future questions. I will discuss case studies on how we are applying genomic methods for recovery of several imperiled plant species. For example, we are currently employing target capture techniques to build a breeding program for Torreya taxifolia, to address hybridization in ex situ collections of Magnolias, to characterize population genetic structure to inform translocation of Rhododendron chapmanii among others. With the ever decreasing costs associated with genomic sequencing, we hope that genomics will continue to inform innovative conservation strategies worldwide.
