Nucleotide Sequence of A High-Molecular-Weight Glutenin Gene in Wheat

Xin Hua, Jiang Ying,Huang Wei-da, Gu Qi-min and Sun Chong-rong   

Abstract: Subclones of a wheat (Triticum aestivum L. cv. asarce) genomic recombinant containing high-molecular-weight (HMW) glutenin gene were constructed by using pUCll8/pUCll9 vectors, their successive shorter deletions were also prepared: The nucleotide sequence of about 560 bp upstream of initiation codon and total coding region was analysed by Sanger's dideoxynucleotide chain termination method. It has 3067 bp which includes 830 codons and reveals high homology with a previously reported HMW glutenin gene. This gene contains no intron but a TAA termination codon within the coding region. Whether this is a silent gene or not merits further investigation.

Key words: Wheat, High molecular weight glutenin gene, Nucleotide sequence
