Microgametogenesis in angiosperms results in two structurally and functionally different cells, one generative cell, which subsequently forms the sperm cells, and the vegetative cell. We analysed the chromatin properties of both types of nuclei after first and second pollen mitosis in rye (Secale cereale). The condensed chromatin of generative nuclei is earmarked by an enhanced level of histone H3K4/K9 dimethylation and H3K9 acetylation. The less condensed vegetative nuclei are RNA polymerase… CONTINUE READING
