Figure 4

Phylogenetic relationships (A) and Circos plots (B,C) showing chromosomal homology and synteny blocks identified between C. picta turtle (CPI) and selected sauropsid genomes. Panel A: ‘26′ denotes the chromosome number of Gopherus evgoodei inferred by Simison et al. (2019) from that of close relatives [13]. The short branch length between LAG and (ACA+TEL) should not be confused with a polytomy. Panels B and C: Colored blocks represent C. picta turtle scaffolds within an individual chromosome. Black and grey blocks represent individual chromosome in the each sauropsid vertebrate. CPI = Chrysemys picta, TSE = Trachemys scripta elegans, GEV = Gopherus evgoodei, DCO = Dermochelys coriacea, GGA = Gallus gallus, LAG = Lacerta agilis, ACA = Anolis carolinensis, TEL = Thamnophis elegans. Phylogenetic tree modified from Valenzuela (2018) [34]. Zooming in Panel C permits visualization of the detailed circos plots (see also Figure S2 for enlarged circos plots).
