Fig. 1From: Chromosome-level genome assembly and population genomics of Mongolian racerunner (Eremias argus) provide insights into high-altitude adaptation in lizardsPhylogenetic analysis and chromosome synteny of squamate genomes. a Phylogenomic tree constructed using common single-copy orthologous genes from 12 lizards and six snakes, with the chicken as the outgroup. The Mongolian racerunner is highlighted in magenta. All animal pictures are from http://reptile-database.reptarium.cz [26], modified in Adobe Illustrator. b Functional enrichment result of Mongolian racerunner genes located at chromosome breakpoint regions caused by chromosome fissions/fusions. c Six genes (RUNX2, TFAP2B, OSR1, WDPCP, TBX5, and TBX3) which have a role in limb development were detected in the chromosome breakpoint regions. d–f Four genes (CRISP1, CRISP2, FCN2, and SPINT1) which have a role in rattlesnake venom formation were detected in the chromosome breakpoint regions. g The reconstruction of ancestral chromosomes in squamates and chicken genomes. The Chr Z of three species originated from five different autosomesBack to article page
