Table 2 Classification and nomenclature of B. pendula PR-10 sequences from our cultivars and GenBank. Indicated are the subfamily (I to V), gene designations (PR-10.01A to PR-10.05), allergen designation if the genes are known to be pollen expressed (Bet v 1.01A to Bet v 1.02C), and allele names as defined in Figure 2. Known isoforms [19] are shown, followed, between brackets, by the GenBank accession number. The tissue of origin is shown in case of mRNA-derived GenBank sequences (L = leaves, R = roots, P = pollen).
