Analysis of nucleosomal deoxyribonucleic acid in a higher plant.


ABSTRACT: Comparisons of nuclease digestions of chromatin in nuclei from rye embryos and rat liver show that their nucleosomal DNA is similar, i.e. DNA subunits consist of 200 base-pair repeats with 140 base-pair cores of identical substructure. The identical nucleosome structure is present in nuclei from cells of rye embryos that have been non-viable (i.e. dead) for more than 7 years. These findings indicate a high degree of stability of the DNA-histone complex and are consistent with conservation of the nucleosomal structure of chromatin during evolution.
