Cross-reaction for PR-10 protein

The PR-10 protein has a high cross-reaction between pollen-pollen and pollen-plant food.

Today I want to talk about the major protein of the beech family – birch, hazel (hazel), alder, beech, oak and hornbeam. Consider which plant foods contain the most PR-10 protein.

Protein PR-10 is a so-called defense protein or pathogenic protein.
Pathogenic proteins are synthesized in plants under the influence of stressful situations, such as infection, ultraviolet radiation, unfavorable meteorological conditions, mechanical damage. In some tissues and organs of plants, for example, in pollen or fruits, these proteins are especially abundant.

PR-10 protein breaks down when heated and digested, so cooked food usually does not cause reactions.
