Abstract

For the purpose to detect the so-called DNA-like fibrils, “DNA fibril complexes”, in chloroplasts and mitochondria of the cells at several stages of the life cycle, the cells of endosperm, egg, proembryo, embryo, leaf and pollen of Ginkgo biloba, were examined by electron microscopy. As the result DNA fibril complexes have been found in both chloroplasts and mitochondria of the cells at all the stages of the life cycle as far as the present observations are concerned without any exception. Therefore, it is suggested that the DNA fibril complex persists in every stages throughout the life cycle of plant.
