Summary

Rice glutelin cDNA clones were isolated from a rice cDNA library constructed from immature endosperm. The isolated glutelin cDNA clones could be divided into two classes by restriction site polymorphism and sequence. They encoded polypeptides containing the same number of amino acids including a 24 amino acid signal peptide, a 282 amino acid acidic subunit and a 193 amino acid basic subunit. The coding regions were 95% homologous to each other at the nucleotide and amino acid levels. Southern hybridization analysis revealed that there were four or five copies of glutelin genes per haploid rice genome.
