Fig 1.

Gene maps of Chaetosphaeridium cpDNA (A) and mtDNA (B). Genes outside each map are transcribed clockwise. Genes absent from Marchantia cpDNA and mtDNA are represented in beige. Gene clusters shared with Marchantia are shown as series of green and red boxes. Genes present in Marchantia but located outside conserved clusters are shown in gray. tRNA genes are indicated by the one-letter amino acid code followed by the anticodon in parentheses. Intron-containing genes are denoted by asterisks, with the introns represented as open boxes. The intron sequences bordering the rps12 exons (rps12a and rps12b) are spliced in trans at the RNA level.
