title: Synaptonemal complexes in antheridia of Achlya ambisexualis E87.
abstract: This is the first report of longitudinal sections of synaptonemal complexes in oömycetous fungi. These indicators of meiosis were observed in antheridial nuclei of Achlya ambisexualis E87. They were attached to a platelike structure at the inner membrane of the nuclear envelope. The lateral elements were separated from each other by an average distance of 160nm. These results provide new ultrastructural evidence for gametangial meiosis in Oömycetes.
