Figure 4From: The evolution of vertebrate somatostatin receptors and their gene regions involves extensive chromosomal rearrangementsPhylogenetic maximum likelihood trees of the FNG and FSCN gene families. The fringe homolog (FNG) and fascin homolog 1 and 2 (FSCN) gene families are neighboring gene families of the SSTR2, -3 and -5 chromosomal regions. Phylogenetic methods, monophyletic clusters and leaf names as in Figure 2. All neighboring gene family trees for the SSTR2, -3 and -5-bearing regions, including NJ analyses and all branch support values, are shown in Figure S21-S50 (see Additional file 6).Back to article page
