Phylogeny in Structure Alterations of Poaceae cpDNA
The aim was to research the relationship between structure alterations of chloroplast DNA and phylogeny. The structural alterations of the chloroplast genome found in grass chloroplast DNA in comparison with that of tobacco was systematically surveyed. (1) three inversions in the large single-copy region; (2) degradation of the gene accD, ycf1, ycf2; (3) deletion of intron in the gene clpP, rpoC1; (4) changes of IR/SC bordery, mostly occurred at the family level, but some alterations showed time hierarchy. These phylogenetic relationships were supported by the phylogenetic tree with introns of cpDNA. Structural analysis of the chloroplast genome is applicable to the phylogenetic reconstruction of related plants.
