Natural diversification of the Cor a 1 (panel a), Cor a 2 (panel b), and Cor a TLP (panel c) orthogroups identified in C. avellana, C. americana, C. heterophylla and C. mandshurica genomes. The evolutionary history of 58 Corylus genes was used together with three well-characterized allergenic genes to perform a maximum likelihood analysis. Labels showing the bootstrap values higher than 50 (out of 100) are indicated above the branches. The taxa to which the protein sequences belong are indicated by colored spots
