Meiosis in Aspergillus nidulans: another example for lacking synaptonemal complexes in the absence of crossover interference

Immature cleistothecia of A. nidulans were serial sectioned and studied by electron microscopy. Synaptonemal complexes or other conspicuous signs of chromosomal pairing were not observed in this material. This deviation from most other eukaryotes may be of significance for explaining the likewise un...

description Immature cleistothecia of A. nidulans were serial sectioned and studied by electron microscopy. Synaptonemal complexes or other conspicuous signs of chromosomal pairing were not observed in this material. This deviation from most other eukaryotes may be of significance for explaining the likewise unusual absence of crossover interference in this organism, as well as in Schizosaccharomyces pombe . In addition, the authors report on division spindles and spore formation in A. nidulans .
