| Abstract: | The gene encoding B1 hordein of Hordeum vulgare (cv. Donetsky 4) was cloned and entirely sequenced. It contains no introns and codes for of 293 amino acids long polypeptide with molecular weight 33418. Our clone differs from the previously sequenced B1 hordein genes in some positions within the coding region (there are 4 nucleotide changes and a 12 bp deletion, as compared with the pB11 cDNA clone, and 5 nucleotide changes, as compared with the pBHP184 genomic clone). These changes result in polymorphism of amino acid sequences at 5 positions. 5'-flanking region contains putative regulatory and promoter sequences and differs from that of the pBHP184 clone in 3 positions. |
