Fig. 3: Chromosome structure and collinearity of Pha. aphrodite, D. chrysotoxum, V. planifolia, P. zijinensis and P. guangdongensis.
From: Genomes of leafy and leafless Platanthera orchids illuminate the evolution of mycoheterotrophy
Chromosome comparison for P. zijinensis and P. guangdongensis shows almost perfect collinearity except for two rearrangements within Chr 5 and Chr 7, and two translocations (see also Supplementary Fig. 6). In comparison with P. zijinensis and P. guangdongensis, the differences in chromosome number of three other orchid genomes exhibited major chromosome rearrangement events.
