Polymorphism for a 42-kb chloroplast DNA inversion was detected in five species of Abies and two species of Tsuga based on a sample of 1,281 individuals and both Southern hybridization and polymerase chain reaction (PCR) analyses.

Since Palmer (1983) originally doc-umented this phenomenon in Phaseolus vulgaris, it has been con- Species in 9 of the approximately 650 genera of the flowering plant family Leguminosae are known to possess a large (50-kb) inversion in their chloroplast genomes, relative to the gene order found most commonly among land plants.

Major rearrangements of the chloroplast ge-nome, such as inversions, are rare and thought to be evolutionarily stable events (Palmer 1987). In several recent studies of a number of diverse angiosperm groups, chloroplast DNA structural mutations have proven useful as taxonomic markers [e.g., 22 kb inversion in Asteraceae Many chloroplast DNAs contain two inverted repeats, which separate a long single copy section (LSC) from a short single copy section (SSC). The inverted repeats vary wildly in length, ranging from 4,000 to 25,000 base pairs long each. The chloroplast DNA (cpDNA) inversion in the Asteraceae has been cited as a classic example of using genomic rearrangements for defining major lineages of plants.

In addition, the P. ovata plastome contains 149 plast DNA inversion among 80 species representing 16 tribes of the Asteraceae and 10 putatively related families. Filter hy-bridizations using cloned chloroplast DNA restriction frag-ments of lettuce and petunia revealed that this 22-kilobase-pair inversion is shared by 57 genera, representing all tribes of the The chloroplast DNA (cpDNA) inversion in the Asteraceae has been cited as a classic example of using genomic rearrangements for defining major lineages of plants. We further characterize cpDNA inversions in the Asteraceae using extensive sequence comparisons among 56 species, including representatives of all major clades of the family and Filter hybridizations using cloned chloroplast DNA restriction fragments of lettuce and petunia revealed that this 22-kilobase-pair inversion is shared by 57 genera, representing all tribes of the Asteraceae, but is absent from the subtribe Barnadesiinae of the tribe Mutisieae, as well as from all families allied to the Asteraceae.
