Molecular Characterization of Group I Allergens of Grass Pollen

The Group I allergens of grass pollen are one of the most widely spread and ubiquitous groups of glycoproteins that have been characterized in pollen grains (Johnson and Marsh, 1965a). Members of this group have been found in the pollen from a number of subfamilies of the Poaceae and are found in all the clinically important grasses (Table 7–1). Group I allergens from pollen of most grasses are major allergens (Ansari et al., 1987; Matthiesen et al., 1991). The most well characterized Group I allergens come from the clinically important grasses: ryegrass, Kentucky bluegrass, timothy, and orchard grass have been designated Lol p I, Poa p I, Phl p I, and Dac g I respectively (Marsh et al., 1987). A more recently studied allergen is Cyn d I from Bermuda grass, which has historically been considered to have different allergens from those of other clinically important grasses (Watson and Kibler, 1922; Marsh et al., 1970).
