Abstract
Two of the major allergens in the pollen of short ragweed are Amb a I and Amb a II (formerly antigen E and antigen K, respectively). The genes for Amb a I and Amb a II have recently been cloned, and it was shown that Amb a I is a family of proteins with at least three distinct polymorphic family members. This study addresses the number of individual Amb a I and Amb a II family members, the polymorphism in each family member and the expression of these genes in ragweed plants from different geographical locations. This work led to the cloning and characterization of a fourth Amb a I family member, designated Amb a I.4.Entities:
