Summary

Pollen from 10 agricultural plant species was surveyed for the presence of proteins crossreactive with group I, group IV and group IX allergens. Barley (Hordeum vulgare), maize (Zea mays), rye (Secale cerale), triticale (xTriticosecale cereale), oats (Avena saliva), Canola (Brassica napus) and sunflower (Helianthus annux) pollens contained numerous allergen cognate proteins. Northern blot analysis of barley pollen RNA revealed the presence of group I and group IX allergen transcripts. The barley pollen cDNA hvp9742, and three other cloned allergens: phlenum protense (Phip) V, Phl p Va and Lolium perenne (Lol p) 1b, were demonstrated to have extensive nucleotide and amino acid sequence similarity to the Poa p IX isoallergens. It was concluded that hvp9742 represents a Poa p IX isoallergen homologue expressed by barley pollen, and was therefore designated Hor v IX. It is further shown that the most highly conserved domains of all seven proteins, including Hor v IX, map to previously defined Poa p IX antibody binding epitopes.
