What is Multiple recent horizontal transfers of the cox1 intron in Solanaceae and extended co-conversion of flanking exons about?
## Background The most frequent case of horizontal transfer in plants involves a group I intron in the mitochondrial gene __cox1__, which has been acquired via some 80 separate plant-to-plant transfer events among 833 diverse angiosperms examined. This homing intron encodes an endonuclease thought to promote the intron's promiscuous behavior. A promising experimental approach to study endonuclease activity and intron transmission involves somatic cell hybridization, which in plants leads to mitochondrial fusion and genome recombination. However, the __cox1__ intron has not yet been found in the ideal group for plant somatic genetics - the Solanaceae. We therefore undertook an extensive survey of this family to find members with the intron and to learn more about the evolutionary history of this exceptionally mobile genetic element. ## Results Although 409 of the 426 species of Solanaceae examined lack the __cox1__ intron, it is uniformly present in three phylogenetically disjunct clades. Despite strong overall incongruence of __cox1__ intron phylogeny with angiosperm phylogeny, two of these clades possess nearly identical intron sequences and are monophyletic in intron phylogeny. T
