Figure 1 Gene map of the chloroplast genome of Alsophila denticulata.Genes located in outside of the outer circle are transcribed in thecounterclockwise direction, whereas those inside are transcribed in the clockwise direction. Color codes represent different functional gene groups. In the middlecircle, the GC and AT content variations are indicated by darker gray and lighter gray, respectively.
