The distribution of structural alterations of the chloroplast genome found in grass chloroplast (cp) DNA in comparison with that of tobacco was systematically surveyed in the cpDNAs of monocots. Southern hybridization and/or PCR analyses for the detection of (1) three inversions in the large single-copy region, (2) loss of an intron in the rpoC1 gene, (3) an extra-sequence insertion in the rpoC2 gene, (4) the deletion of ORF2280, (5) rearrangements of the accD (ORF512) gene, and (6) non-reciprocal translocation of the rpl23 gene, were carried out on cpDNAs isolated from 58 species, 22 families, and 11 orders, which covered almost all families of monocots. These structural alterations of cpDNA mostly occurred at the family level. However, only part of the Restionaceae possessed the inversion that characterizes the lineage of grass differentiation. The order of mutational events made it possible to reconstruct grass phylogeny in monocots. Since no variations in structural alterations of the cpDNA were found among the Poaceae, grass plants were inferred to have originated from an ancestor harboring these structural alterations of the chloroplast genome. These phylogenetic relationships were supported by the sequence data of rbcL.
