  abstract  = {Sexually reproducing organisms depend on meiosis for the generation of haploid, genetically diverse gametes to maintain genome stability and the potential to adapt to changing environments. Haploidization is achieved through two successive rounds of cell division after a single initial pre-meiotic DNA replication. Meiosis I segregates the homologous chromosomes, followed by the segregation of the sister chromatids in meiosis II. Genetic diversity is achieved through the process of recombination that de-scribes the exchange of genetic material between the maternal and paternal homolog. Recombination and the initial steps of haploidization are executed already early on in prophase I. Both essential processes depend on a variety of multiprotein complexes, such as the linker of nucleo- and cytoplasm (LINC) complex and the synaptonemal complex (SC). The structure of multiprotein complexes is adjusted according to their function, environment, and the forces they are subjected to. Coiled-coil domains typical in load-bearing proteins characterize the meiotic mechanotransducing LINC complexes. SCs resemble ladder-like structures that are highly conserved amongst eukaryotes, while the primary sequence of the proteins that form the complex display very little if any sequence homology. Despite the apparent significance of the structure to their function, little quantitative and topological data existed on the LINC complexes and the SC within their morphological context prior to the present work. Here, the molecular architecture of the meiotic telomere attachment site where LINC complexes reside and the SC have been analyzed in depth, mainly on the basis of electron microscope tomography derived 3D models complemented by super-resolution light microscopic acquisitions of the respective protein components.},
