- Abstract
Summary Mitotically dividing cells of Secale cereale , Hordeum vulgare and Vicia faba were studied by indirect immunofluorescence using an antibody recognizing phosphorylated histone H3. The study revealed the following features: (i) the H3 phosphorylation starts at prophase and ends at telophase in the pericentromeric chromatin, is associated with the condensation of mitotic chromosomes and is independent of the distribution of late replicating heterochromatin. (ii) Compared with other chromosome regions, the pericentromeric chromatin is histone H3 hyperphos- phorylated. (iii) The study of a semi-dicentric chromo- some revealed that only at intact centromeres is the chromatin hyperphosphorylated at H3.
