Does anyone know in which species the grass allergen Phl p5 occurs? It was originally isolated from the grass species Phleum pratense so it must at least occur in that species. It stand to reason that it might also occur in other species of the genus Phleum. A few papers states that it is universal in many grasses, but with poor documentation.

Can anyone provide conclusive evidence and/or references in which the authors state in which species (or cultivars) the allergen occurs and/or have been isolated from? I welcome answers from all researchers along with special interest from expert knowledge primarily from plant ecology, aerobiology, immunology and other health professionals.
