Figure 4.- Maximum likelihood tree of CYPᵀsequences from 44 individuals of Primula vulgaris (17 short-styled and 27 homostylous, boldfaced) sampled for this study, plus CYPᵀ sequences from two homostylous individuals (indicated with *) previously reported as CYPᵀ SLH1 and SLH2 (Li et al., 2016), and a CYPᵀ sequence from an S-individual of Primula veris (GenBank: KX589238) as outgroup. Each accession at the tips is labeled from left to right with population number, individual number, and floral morph type (S and H). Accessions from H-individuals are boldfaced; accessions from the same population have the same color (see also Fig. 2). Bootstrap support values ≥ 80 are indicated below to the branches.
