Utilization of Next-Generation Sequencing to Resolve Uncertain Relationships in the Asparagales.

The Asparagales is a monocot order of diverse flowering plants that include important crops such as asparagus and onion as well as horticulturally important plants like irises, daffodils, and orchids. Previous attempts to construct the phylogenetic tree of families within the Asparagales relied on seven gene regions from across the genome and revealed many clades that had very low levels of support. Many of these problematic branches were located in a paraphyletic group termed the “Lower Asparagales.” This group encompasses all of the families between the base of the tree (Orchidaceae) and the Iridaceae lineage, while the remaining taxa fall under the core Asparagales. Recently, we completed a study on the “core” or “Higher” Asparagales using next generation sequencing approaches. In this project, we use similar methods to acquire plastome and other sequences to construct a phylogenetic tree of the “Lower Asparagales” to resolve problematic relationships among families. This project will address these questions: Are orchids sister to the Asteliod clade (Boryaceae, Blandfordiaceae, Lanariaceae, Asteliaceae, Hypoxidaceae)? Are Ixioliriaceae and Tecophilaeaceae sister taxa, or should they belong in different parts of the tree? The results from this project will set the stage for future investigations within the Orchidaceae.
