Summary edit
| Description |
English: Course of sexual reproduction phases of the dinoflagellate Prorocentrum micans. (A)–(I): Haploid vegetative cells functioning as isogametes (A) become paired by means of their respective apical spines (B); then the donor cell injects its nucleus with stretched chromosomes into the receiver cell (C). (B), (C), (F), (F’): In vivo DAPI staining cells: (B) corresponds to B, (C) to (C), F to (F). After the two nuclei merge, (D) the zygote is diploid (E) and crossing over of the chromosomes can occur. Chromosomes become completely unwound and stretched. In the resultant diploid nucleus (F), chromatin begins to spin round (chromatic cyclosis) giving a rounded shape to the nucleus, as shown in the photograph (F). (F’): Detail of chromosome disorganised structure in a Transmission Electron Microscopic (TEM) view during the nuclear spin. Only one meiotic division occurred (G, G’, H), leading to 2q DNA-containing cells (I). Scale bar = 1 µm.
