Cultivated Rye Grass, G12

Globally, grass pollens are a significant cause of IgE-mediated allergy, affecting approximately 40% of all grass allergic patients. Cultivated rye (Secale cereale) is one of the major cereal crops globally. It is used as feed for farm animals. It is widely distributed over the temperate regions of the northern hemisphere and pollinates by the wind. Cultivated rye grass (S. cereale; g12) should not be confused with perennial ryegrass (Lolium perenne; g5); rye, the foodstuff (Secale cereale; f5); and the Wild Rye grass (Elymus tricoides; g70). The pollinating season of cultivated rye varies between May and August, differing according to the geographical location. Its pollens are shed in huge amounts and are considered as a significant triggering factor for acute allergic symptoms like conjunctivitis, allergic rhinitis, and asthma in individuals sensitized to grass pollens. Sensitization to pollens of cereals is widespread. Cultivated rye shows extensive cross-reactivity with the other species of Pooideae family including Timothy grass and perennial ryegrass
