Synaptonemal Complexes

A method is described for obtaining synaptonemal complex preparations from mouse pachytene oocytes for light and electron microscopic examination. A karyotype based on the whole complement of synaptonemal complexes of a pachytene oocyte as visualized by electron microscopy is presented.

Light and electron microscopy have revealed that the meiotic-1 (mei-1) mutant of Neurospora crassa is defective in chromosome pairing (asynaptic) although plenty of axial components of the synaptonemal complex are produced and occasional tripartite synaptonemal complexes can be formed. The mei-1 mutant is most probably defective in bringing the homologous chromosomes together for pairing and for assembly of the synaptonemal complex. The mei-1 mutant is also defective in nuclear separation which leads to a four-poled spindle at the subsequent division. The lack of chromosome pairing, the incomplete assembly of the synaptonemal complex, and the four-poled spindles account for absence of recombination and for the nondisjunction found in genetic analysis.

Meiosis I

Meiosis was examined in plasmodia of the protist Plasmodiophora brassicae within artificially inoculated cabbage roots, using light and electron microscopy. Meiotic nuclear divisions occur following the cessation of vegetative growth of the Plasmodium. Synaptonemal complexes develop in nuclei of the “akaryote stage,” which represents prophase I. Meiosis I and II take place concurrently with cleavage of the Plasmodium into resting sporangia. Previous reports of synaptonemal complexes and sporangiogenic meiosis in the Plasmodiophorales are thus corroborated. Centrioles are paired and bipolar until the end of meiosis I; then they separate and migrate to opposite poles, without replicating, between prophase II and metaphase II. Centrioles elongate considerably between prophase I and the end of meiosis II, then appear to disintegrate as uninucleate resting sporangia are formed and are absent from mature sporangia.
