Desoxyribonucleic-acid-containing bodies in the cytoplasm of pollen mother cells at early meiotic prophase


, : Desoxyribonucleic-acid-containing bodies in the cytoplasm of pollen mother cells at early meiotic prophase. Genetics 32(1): 107

Feulgen-positive bodies are present in the cytoplasm of pollen mother cells in several genera of plants (Lilium, Trillium, Allium, Paeonia and others). It is suggested that they may function as a modification of the more common type of heterochromatin-nucleolus mechanism controlling nucleic acid synthesis.
