Abstract A Hind III-generated fragment of wheat embryo nuclear DNA has been cloned and sequenced. The cloned fragment corresponds to a 1241 bp long, moderately repeated (60 000 copies/genome) segment of the genomic DNA. The repeat is AT-rich (67%), contains an open reading frame for 151 amino acids and several nucleotide blocks resembling the consensus domain of autonomously replicating sequences. Southern blot hybridization analyses indicate that the repeat is scattered through the wheat genome. A sequence homologous to this repeat occurs also in rye embryo nuclear DNA where it shows the same dispersion pattern as that observed for the wheat repeat.
