Figure 2

Seven representative plastomes of Vanilloideae. Pogonia japonica has the longest plastome, with 158.2 kb. Pogonia and Vanilla are the photosynthetic species, while Cyrtosia and Lecanorchis are the nonphotosynthetic mycoheterotrophic species. A few photosynthesis-related genes or pseudogenes remain in Cyrtosia, while all photosynthesis-related genes have been lost in Lecanorchis. Green gene boxes indicate genes related to the light reaction of photosynthesis. L. kiusiana and L. japonica hold only 33 and 32 gene regions, respectively. The heavy vertical lines indicate inverted repeat (IR) regions. The dashed lines indicate the single copy (SSC) regions.
