Estimating species relationships within Pueraria s.s.: combining phylogenies and networks.

Pueraria is a genus in the Fabaceae family that is recognized as a polyphyletic grouping. Although phylogenetic work has begun on Pueraria, certain species relationships remain unresolved, especially within Pueraria sensu stricto. This research hopes to expand on previous work by using a robust collection of 103 accessions across 4 gene regions from both the chloroplast (matk, trnD-trnT) and nuclear (AS2, ITS) genomes to help parse unresolved relationships within Pueraria s.s. This work will help delimit species within Pueraria s.s. particularly those within the kudzu species complex, which includes the invasive pest kudzu (Pueraria montana var. lobata), and will address the relationship between Pueraria and the sister genus Nogra. Making use of nuclear vs. chloroplast markers will also enable us to detect evidence of hybridization among species using phylogenetic and network analyses. Our results will improve understanding of the evolutionary processes at work to create extant species diversity within Pueraria and inform potential taxonomic revisions.
