A number of plant proteins, which all seem to be involved in pathogen defense
response, are structurally related [1,2,3]. These proteins are:
Bet v I, the major pollen allergen from white birch. Bet v I is the main
cause of type I allergic reactions in Europe, North America and USSR.
Aln g I, the major pollen allergen from alder.
Api G I, the major allergen from celery.
Car b I, the major pollen allergen from hornbeam.
Cor a I, the major pollen allergen from hazel.
Mal d I, the major pollen allergen from apple.
Asparagus wound-induced protein AoPR1.
Kidney bean pathogenesis-related proteins 1 and 2.
Parsley pathogenesis-related proteins PR1-1 and PR1-3.
Pea disease resistance response proteins pI49, pI176 and DRRG49-C.
Pea abscisic acid-responsive proteins ABR17 and ABR18.
Potato pathogenesis-related proteins STH-2 and STH-21.
Soybean stress-induced protein SAM22.
These proteins are thought to be intracellularly located. They contain from
155 to 160 amino acid residues. As a signature pattern, we selected a
conserved region located in the third quarter of these proteins.

The gene coding for the major birch pollen allergen Betv1, is highly homologous to a pea disease resistance response gene.
