The single-copy gene encoding high-mobility-group protein HMG-I/Y from pea contains a single intron and is expressed in all organs.
The coding and 3'-downstream regions of the gene encoding the high mobility group protein HMG-I/Y from pea have been isolated, sequenced and characterised. A 795 bp pea genomic fragment containing the coding region of the pea HMG-I/Y gene with a single intron of 201 bp was isolated by PCR. The gene encodes a protein of 197 amino acid residues with four copies of the AT-hook DNA-binding motif encoded by exon 2. Southern blot analysis on genomic DNA revealed the presence of a single copy of the HMG-I/Y gene in the haploid genome. The pea HMG-I/Y gene is expressed in all organs of pea including roots, stems, leaves, flowers, tendrils and developing seeds, as determined by northern blot analysis.
