The Utility of Low-copy Nuclear Genes in Resolving Phylogenetic Relationships and Uncovering Hybridization Across the Campanuloideae Clade (Campanulaceae).

The Campanuloideae include over 1000 species found primarily in the Northern Hemisphere. Recent phylogenetic studies based on chloroplast markers have been quite successful at resolving deep-level relationships but relationships at lower taxonomic levels remain unknown or uncertain. Here we present results based on two low-copy nuclear loci from the PPR gene family (AT1 and AT3) as well as the G3PDH (or GapC) gene. These three nuclear markers, in addition to five chloroplast markers, provide greater resolution than has previously been obtained and allow us to better understand processes such as hybridization and introgression occurring within this group.
