FIGURE 1.

Bulbophyllum regnellii plastid genome. Genes shown on the outside of the circle are transcribed clockwise; genes on the inside are transcribed counterclockwise. The color of the gene boxes indicates the functional group to which the gene belongs. The thick lines indicate the length of the inverted repeats (IRA and IRB), separated by the large single-copy (LSC) and small single-copy (SSC) regions. The dashed darker gray area in the inner circle indicates genome GC content, whereas lighter gray area indicates AT content.
