A group I intron has recently been shown to have invaded mitochondrial cox1
genes by horizontal transfer many times during the broad course of
angiosperm evolution. To investigate the frequency of acquisition of this
intron within a more closely related group of plants, we determined its
distribution and inferred its evolutionary history among 14 genera of the
monocot family Araceae. Southern blot hybridizations showed that 6 of the
14 genera contain this intron in their cox1 genes. Nucleotide sequencing
showed that these six introns are highly similar in sequence (97.7%-99.4%
identity) and identical in length (966 nt). Phylogenetic evidence from
parsimony reconstructions of intron distribution and phylogenetic analyses
of intron sequences is consistent with a largely vertical history of intron
transmission in the family; the simplest scenarios posit but one intron
gain and two losses. Despite this, however, striking differences in lengths
of exonic co-conversion tracts, coupled with the absence of co-conversion
in intron-lacking taxa, indicate that the six intron-containing Araceae
probably acquired their introns by at least three and quite possibly five
separate horizontal transfers. The highly similar nature of these
independently acquired introns implies a closely related set of donor
organisms.
