摘要: We report the cloning and nucleotide sequence analysis ofpsbD/C operon from a dicotyledonous tree species,Populus deltoides (poplar). The coding regions ofpsbD andpsbC deduced amino acid sequences show very high homology with those other higher plants. In pairwise alignment of gene sequences,P. clustered annuals rather than withPinus, only whosepsbD/C is available. Comparison several reported showed that synonymous substitutions were distributed in bothpsbD uniformly, throughout length genes. frequency nonsynonymous located amino-terminal endof psbD was distinctly higher, suggesting lower degree structural constraints this region encoded D2 protein. arrangement reading frames Northern suggest organization expression inP. similar to
