title: Gene organization and newly identified groups of genes of the chloroplast genome from a liverwort, Marchantia polymorpha.
abstract: The complete nucleotide sequence of chloroplast DNA from a liverwort, Marchantia polymorpha has made clear the entire gene organization of the chloroplast genome. Quite a few genes encoding components of photosynthesis and protein synthesis machinery have been identified by comparative computer analysis. Other genes involved in photosynthesis, respiratory electron transport, and membrane-associated transport in chloroplasts were predicted by the amino acid sequence homology and secondary structure of gene products. Thirty-three open reading frames in the liverwort chloroplast genome remain unidentified. However, most of these open reading frames are also conserved in the chloroplast genomes of two species, a liverwort, Marchantia polymorpha, and tobacco, Nicotiana tabacum, indicating their active functions in chloroplasts.
