Fig. 2: Acorus shows the slowest synteny loss rate and substitution rate.
From: The slow-evolving Acorus tatarinowii genome sheds light on ancestral monocot evolution

a, Distributions of syntenic gene retention from the five outgroup species in 42 monocot species shown in coloured bars. b, Comparison of ‘syntenic block size’ decay among different monocot species when compared with the outgroup Amborella. c, An example of stronger synteny retention in Acorus than in Zestora when compared with the outgroup Aristolochia. d, Significant negative correlation between the number of syntenic genes retained in Amborella and the sum of the branch lengths in the MRCA of monocots based on the concatenated single-copy gene tree for 42 monocots (blue dots). Error bands represent 95% confidence intervals based on a binomial model.
