Figure 1.
Gene map of Erycina pusilla chloroplast genome.
Genes on the outside of the map are transcribed clockwise whereas genes on the inside of the map are transcribed counterclockwise. Colors indicate genes with different functional groups.
Figure 2.
Comparison of chloroplast genomes of E. pusilla, Onc. Gower Ramsey, and P. Aphrodite.
Deletions or insertions longer than 70 bp in P. aphrodite or Onc. Gower Ramsey in comparison with E. pusilla are labeled as white triangles or black triangles individually. Highly diverse sequence regions larger than 500 bp are labeled with black blocks. Numbers indicate the longest length of comparative deletions, insertions, or diverse sequence retions of three species orchids.
Figure 3.
Structure of ndh genes in 3 orchid cp genomes.
Numbers indicate the position in the chloroplast genome. The angled dashed lines indicate the gaps. Different colors indicate different ndh genes, a color key is shown at the bottom of each part of the Figure. Accession number of O. sative Japonica is NC_001320.
Figure 4.
Variations in 5 regions in 19 Epidendroideae species.
Numbers indicate the positions of the chloroplast genome. The angled dashed lines indicate deletions. The green triangle indicates an insertion. The yellow areas indicate diverse sequences. 1including Calanthe discolor and Calanthe sylvatica; 2including Geodorum densiflorum; 3including Cymbidium aloifolium and Geodorum densiflorum.
