杂色沙蜥生活在中国戈壁沙漠的干旱地带。我们分析了来自三个不同地点的种群，这些地点在基质颜色和海拔高度上有所不同：黑山口（HSK）、瓜州县（GZ）和额济纳旗（EJN）。基质颜色为浅黄色（GZ-y）、黄色（EJN-y）或黑色（HSK-b）;相应的蜥蜴种群颜色在很大程度上与其基质的黑化程度相匹配。我们组装了P. versicolor基因组，并对来自三个不同种群的90多个个体进行了测序。种群间的遗传分化与其地理分布相对应。我们推断了这些种群之间的遗传关系，并使用选择扫描和差异表达来识别显示选择特征的基因。在其他基因中，Slc 2a 11和akap 12是高度分化的，并且可能负责色素对杂色紫菜基质颜色的适应。
The variegated toad-headed agama, Phrynocephalus versicolor, lives in the arid landscape of the Chinese Gobi Desert. We analyzed populations from three different locations which vary in substrate color and altitude: Heishankou (HSK), Guazhou County (GZ), and Ejin Banner (EJN). The substrate color is either light-yellow (GZ-y), yellow (EJN-y), or black (HSK-b); the corresponding lizard population colors largely match their substrate in the degree of melanism. We assembled the P. versicolor genome and sequenced over 90 individuals from the three different populations. Genetic divergence between populations corresponds to their geographic distribution. We inferred the genetic relationships among these populations and used selection scans and differential expression to identify genes that show signatures of selection. Slc2a11 and akap12, among other genes, are highly differentiated and may be responsible for pigment adaptation to substrate color in P. versicolor.
