Abstract

PR-10 is an ubiquitous part of plant proteomes that are reported as homologues proteins to the Bet v 1, that was found previously to be a major birch-pollen allergen. In many plant species, PR-10 proteins are involved in allergic cross-reactions of sensitive patients. Despite their clinically relevance, PR-10 proteins are still not reported and characterized in every plant species yet. Here, a marker-based technique is reported to describe genomic variability of the length polymorphism based on the sequences of homologous genes to Bet v 1 group. BBAP (Bet v 1 homologs based amplified profile) method was applied to analyse the polymorphic variability of thirty fruit species and to analyse the generated fingerprint differences among them. A total number of generated loci was 682 and polymorphism reach 100%. The most different BBAP fingerprints were generated for Rubus nigra and the most similar BBAP profiles were obtained for Annona cherimola and Ananas comosus, Prunus dulcis and Malus domestica, and for Citrus sinensis and Citrus limon. The new type of DNA based molecular marker technique was aproved to be universal and an effective for mapping a variability of coding regions of plant genomes.
