简介
Recent plastid phylogenomic studies have helped clarify the backbone phylogeny of angiosperms. However, the relatively limited taxon sampling in these studies has precluded strongly supported resolution of some regions of angiosperm phylogeny. Other recent work has suggested that the 25,000-bp plastid inverted repeat (IR) region may be a valuable source of characters for resolving these remaining problematic nodes. Consequently, we aligned all available angiosperm IR sequences to produce a matrix of 24,702 aligned bases for 246 accessions, including 36 new accessions. Maximum likelihood analyses of the complete data set yielded a generally well-supported topology that is highly congruent with those of recent plastid phylogenomic analyses. However, reducing taxon sampling to match a recent 83-gene plastid analysis resulted in significant changes in bootstrap support at some nodes. Notably, IR …
