Identification of histone H1.z components in a Muscovy duck (Cairina moschata L.) population.
The general patterns of histone H1 proteins from erythrocyte nuclei of Muscovy duck individuals were similar to those of Pekin type ducks both in acetic acid-urea and 2D polyacrylamide gels. We show here that Muscovy duck histone H1.z in the tested population was represented by three different electromorphs, each presumably encoded by a distinct allelic gene. Accordingly, we have identified six phenotypes consisting of the homodimeric and heterodimeric combinations of the three isoforms. The frequency of the presumptive alleles ranged from 0.506 for the main allele z1 to 0.379 for allele z2 and only 0.113 for the rarest allele z3. In addition to a standard set of somatic H1 variants, an unusual protein X, absent in other avian species, was also revealed.
