See PLOS One Spiric et al., 2015, open access journal. Series of 9 Bet v 1 sequences added at request of Andreas Reuter, PEI, 27 Aug 2015, from 2D Gel and LC-MSMS proteomics of pollen extract. the 9 sequences listed here, match previous cDNA clones by others.

Bet v 1.0116
Bet v 1.0117
Bet v 1.0118

Proof of expression in pollen and high sequence identity to other Bet v 1 isoforms (1 at 75%, the remainder at 85-99% identity).

At its meeting in February 2013, the IUIS Allergen Nomenclature Sub-Committee decided to update the nomenclature of Bet v 1 isoallergens based on the following principles:
1. The database should contain only Bet v 1 sequences whose expression in pollen has been proved at least on the mRNA level.
2. Similar sequences are grouped as variants of an isoallergen if they show >90% sequence identity.
3. Different variant numbers are assigned only to variants with different protein sequences. Nucleotide sequences differing only be silent mutations are not distinguished by the allergen nomenclature.
As a consequence, the following entries were deleted:
Bet v 1.11-Bet v 1.13 and Bet v 1.15-Bet v 1.23.
The following variants were merged into a single entry:
Bet v 1.0101/0102/0103
Bet v 1.0401/0402 (now Bet v 1.0102)
Bet v 1.0601/0602 (now Bet v 1.0104)
Bet v 1.1401/1402 (now Bet v 1.0204)
The following entries were classified as variants of Bet v 1.01:
Bet v 1.01, Bet v 1.04-Bet v 1.08, Bet v 1.10 and Bet v 1.24-Bet v 1.30.
The following entries were classified as variants of Bet v 1.02:
Bet v 1.02, Bet v 1.03, Bet v 1.09 and Bet v 1.14.
