Figure 1.
Bayesian molecular phylogeny of nerve growth factors (NGF).
Branches with the Bayesian posterior probability (B.P.P) of less than 0.85 are highlighted in grey (remaining in colours). Site model 8 (M8) computed ω values for respective lineages are presented. The number of positively selected sites (PP ≥ 0.95) detected by M8’s Bayes-Empirical Bayes (BEB) approach in Elapidae lineage is also indicated. Elapid sequences representing putative duplicate genes are indicated with red labels [NFF: “non-front-fanged” advanced snakes; SCI: Scinciformata].
Figure 2.
Bayesian molecular phylogeny of brain-derived neurotrophic factors (BDNF).
Branches with the Bayesian posterior probability (B.P.P) of less than 0.85 are highlighted in grey (remaining in colours). Site model 8 (M8) computed ω values for respective lineages are presented.
Figure 3.
Bayesian molecular phylogeny of neurotrophin-3 (NT-3).
Branches with the Bayesian posterior probability (B.P.P) of less than 0.85 are highlighted in grey (remaining in colours). Site model 8 (M8) computed ω values for respective lineages are presented.
Figure 4.
Molecular evolution of nerve growth factors.
Three-dimensional homology models of nerve growth factors, depicting the locations of positively selected sites (in red). The ω values (Model 8) for the respective taxa along with the number of positively selected sites (PP ≥ 0.95, Bayes-Empirical Bayes approach) are indicated.
Figure 5.
Molecular evolution of brain-derived neurotrophic factors.
Three-dimensional homology models of brain-derived neurotrophic factors (BDNF), depicting the molecular evolution of these non-venomous homologues. The ω values (Model 8) for the respective taxa (PP ≥ 0.95, Bayes-Empirical Bayes approach) are indicated.
