Comparison of the IR and adjacent sequences from monilophytes. A section of the plastid genome from clpP to trnQ-UUG is presented for selected monilophytes. The section includes the IR, SSC, and parts of the LSC. Genes shown above or below the lines indicate direction of transcription to the right or the left, respectively. The IR is marked by gray boxes, inferred IR extensions are shown by red arrows, and inferred inversions leading to the specific gene arrangement in Polypodiopsida are denoted by black bars. Molecular apomorphies based on gene and intron losses are highlighted by vertical gray lines. Maps are drawn approximately to scale. Color coding of genes corresponds to the legend shown in Figure‚ÄČ 1.
