Figure 2.

Positions of additional gene-coding regions. a) psbDEI minicircle of A. operculatum. A single further gene is proposed between the psbE and psbI genes. b) petD minicircle of A. operculatum. Two further genes are proposed following the petD gene. Diagrams show all three reading frames and the positions of all stop codons (vertical lines). Boxes indicate the positions of the proposed protein-coding regions and also the position of the core region on each minicircle. Minicircles were linearised for graphical display by breaking the minicircle immediately prior to the core region.
