Abstract: Meiosis is a specialized cell division that contributes to halve the genome content and reshuffle allelic combinations between generations in sexually reproducing eukaryotes. During meiosis, a large number of programmed DNA double-strand breaks (DSBs) are formed throughout the genome. Repair of meiotic DSBs facilitates the pairing of homologs and forms crossovers which are the reciprocal exchange of genetic information between chromosomes. Meiotic recombination also influences centromere organization and is es… Show more

“…For instance, mutations in the Arabidopsis thaliana gene DYAD/SWITCH1 (SWI1; At5g51330) functioning in cohesion regulation 28 and its maize and rice homologs, both named AMEI-OTIC1 (GRMZM5G883855 and Os03g44760) 29 , lead to the abrogation of synapsis during meiosis I and rather turn it into a mitotic-like cycle 30 . However, in the Arabidopsis mutants parallel-spindle 1 or Jason, disturbed orientation of the spindle leads to a similar effect 31 . These features are often referred to as examples of FDR 31 and are somewhat common in amphihaploid-and polyhaploid-wide F1 hybrids in which homology is very low and meiotic pairing does not occur 26 .…”

These features are often referred to as examples of FDR 31 and are somewhat common in amphihaploid-and polyhaploid-wide F1 hybrids in which homology is very low and meiotic pairing does not occur 26 . Thus, some researchers consider that this type of meiotic non-reduction is better described as asynaptic-or univalent-dependent 26 .…”

“…As a consequence, it has become a key challenge to integrate recombination rate variation in population genomics in the age of ‘genomic landscapes’ (Booker et al, 2020; Comeron, 2017). The characterization of recombination landscapes also has practical interests since it is likely that changes in CO patterns is to be manipulated for an advantageous purpose, such as creating specific genetic combinations or directly influencing genetic diversity and the adaptive potential of a species (Kuo et al, 2021).…”

“…Understanding the formation of how new meiotic DNA molecules are formed is of special value for breeding since it is a fundamental basis for genetics, evolution, and genomic crop improvement ( Melamed-Bessudo et al, 2016 ; Lambing et al, 2017 ; Blary and Jenczewski, 2019 ; Bolaños-Villegas and Argüello-Miranda, 2019 ; Taagen et al, 2020 ; Kuo et al, 2021 ).…”
