Abstract
Spring pollinosis has become a part of life for many people throughout the world. A wide range of knowledge about the allergenic potential of individual pollen allergen types is documented well, but the starting point of the pollen allergens expression regulation in plants itself is still not fully answered. Expression analysis of pollen allergens does not yet have any specific protocols or methods developed, despite a very good sequence background available in public bioinformatics databases. However, research in this area of interest has a great application potential for breeding and biotechnology of allergenic plants that may benefit from the knowledge of the expression of allergen coding genes in individual varieties or genotypes. Here, a brief review of up-to-date knowledge about the coding sequences of central and eastern European spring pollen allergens is introduced together with real-time based analysis of the expression of two of the main pollen allergens–PR protein type and profilin type of birch and hazelnut.
Highlights
Closely-related and cross-reactive allergens with the Bet v1 were found in the pollen of some other other trees from the order Fagales such as Corylus avellana, Alnus glutinosa or Castanea sativa (Table 2)
20% of all pollen allergic patients react to plant profilins and many of the pollen expressed proteins that bind on IgE in allergic patients have been found to be profilins [32]
Real-time PCR has the potential to be used in routine comparative analysis of allergen expressionin situ and the subsequent health and land management can be applied, such as in the case of the results of different levels of birch Bet v1 expression
Summary
Closely-related and cross-reactive allergens with the Bet v1 were found in the pollen of some other other trees from the order Fagales such as Corylus avellana, Alnus glutinosa or Castanea sativa (Table 2). Fra e is amain pollen allergen of ash that is widely distributed in bothtocentral and northern. The clinical relevance of the ash pollen allergen is quite difficult value because its Europe. The clinical relevance of the ash pollen allergen is quite difficult to value because pollination pollination overlaps with that of Betulaceae [30]. Currently,accession three main isoforms of Fra e 1AY377127.1 are storedand in the in thewith sequence with[30]. CisC is four differences exist in their sequences: in AF526295.1 G is replaced by C in the 135th position, replaced by.
