The matK gene has been among the most useful loci for resolving plant phylogenetic relationships at different evolutionary time-scales, but much less is known about the phylogenetic utility of the flanking trnK intron, especially for deep level phylogenetics. We compared the relative performance of matK and trnK intron regions for resolving the relationships of the early diverging eudicots (angiosperms). The two regions display similar nucleotide compositions and distributions of rate variation among sites. The trnK intron sequences also provide similar levels of phylogenetic information per-site as matK. Combining the trnK intron sequences with matK increases overall bootstrap support for the early diverging eudicots compared to analyses of matK alone. MP, ML and Bayesian analyses provide strong support for eudicots, the sister group relationship of Ranunculales to remaining eudicots, and a Buxales+Trochodendraceae+core eudicots clade. matK and the trnK intron support conflicting positions for Buxales and Trochodendrales in relation to the core eudicots.
