The structural organization and DNA sequence of a wheat histone H4 gene

Abstract
Some wheat histone H4 genes have been cloned from a Charon 4 wheat genomic DNA library using sea urchin histone H4 DNA as a probe. DNA sequence analysis of a cloned gene showed that the deduced amino acid sequence of wheat histone H4 protein was identical to that of pea. The 5' end of wheat histone H4 mRNA was mapped on the cloned gene by the Sl-procedure. Southern blotting analysis of the genomic DNA indicated that histone H4 genes were reiterated 100 to 125 times per hexaploid wheat genome.
