Determining evolutionary diversification and the phylogenetic placement of Lotus subgenus Syrmatium.
Species taxonomic placement is essential to understanding how individuals and populations are related. Taxonomic analyses are important to understanding diversity, management practices, as well as evolutionary diversification. In this project we are examining the evolutionary relationship within Lotus subgenus Syrmatium, a group that contains 11 species with distinct morphological, ecological, and geographic characteristics. I am surveying nuclear ribosomal DNA (nrDNA) and the chloroplast genome using DNA sequencing to gain insight into variation within populations, species, and geographic regions. Data from the internal transcribed spacer (ITS) region of ribosomal DNA allows for phylogenetic examination of relationships in the nuclear genome. In contrast, chloroplast DNA is inherited from the seed producing parent as a single copy, meaning that it undergoes very slow evolution. By comparing the chloroplast genome with the nuclear genome we are able to examine the patterns of change and variation within each. Examining the patterns of diversity will aid our understanding of the phylogenetic placement and evolutionary change within taxa. Lotus taxa can be used to provide insight to speciation events and how the evolutionary units contained within this group need to be managed to maintain diversity.
