Fig. 4From: Genomic sequence analyses of classical and non-classical lamprey progesterone receptor genes and the inference of homologous gene evolution in metazoansThe separated phylogenetic trees of PGRMC1/2 (a), neudesin (b), neuferricin (c) demonstrated the evolutionary relationship among each member of MAPR gene family in metazoans. The trees were constructed using the NJ method with 100 bootstraps. Different clades of PGRMC genes in metazoans are highlighted with different colors (red: vertebrate PGRMC2; pink: vertebrate PGRMC1; blue: invertebrate PGRMC1; black: PGRMC1 out groups). The MAPR genes identified in lampreys are indicated with orange dotsBack to article page
