Summary: During meiosis, ASYNAPSIS 1 (ASY1) promotes inter-homolog recombination, synapsis, and crossover formation. Decreased chiasmata and delayed meiotic prophase I progression were observed in asy1 hypomorphic mutants, while asy1 null mutants showed arrested development. On the other hand, the ectopic recombination between non-homologous chromosomes increased in these mutants. Therefore, asy1 mutants can be used to enhance recombination between wheat wild relatives and elite varieties for accelerating the introgression of important agronomic traits.

Summary: This study identifies a molecular pathway for axis length regulation in meiotic cells. It shows that the cohesin regulator Pds5 interacts with proteasomes to regulate the ubiquitination level of chromosome proteins, which affects chromosome axis length. Two ubiquitin E3 ligases, SCF and Ufd4, are involved in this pathway. These findings contribute to our understanding of how Pds5 regulates meiotic chromosome organization and suggest a conserved regulatory mechanism in higher eukaryotes.

Summary: This study identified a gene, OsPHS1, in rice that is involved in homologous chromosome recognition and pairing during meiosis. Mutations in OsPHS1 resulted in abnormal development of pollen and embryo sacs, leading to male and female sterility in rice plants. The findings suggest that OsPHS1 plays a crucial role in homologous chromosome pairing during rice gametogenesis.

Summary: Mutations affecting crossover frequency and distribution during meiosis can result in aneuploid gametes and sterility. The cytogenetic consequences of colchicine-induced autotetraploids from Arabidopsis mutants with altered crossover frequency were analyzed, revealing the potential of these mutants for studying key proteins in plant meiosis.

Summary: Meiosis is essential for sexual reproduction, and crossover recombination plays a crucial role in establishing connections between homolog chromosomes and promoting genetic diversity. Aberrant crossover patterns can lead to infertility, miscarriage, and congenital disease. Chromosome axis length is involved in regulating the numbers and positions of crossovers, and may contribute to evolutionary adaptation.

Summary: This study provides a comprehensive molecular analysis of telomeres and subtelomeres in barley chromosomes. The findings suggest that these regions play a significant role in the early chromosomal interactions during meiosis in barley, specifically in the homologous recognition and pairing process. Understanding the genome organization of barley and its role in plant breeding is crucial.

Summary: Gametogenesis differs between oocytes and sperm, with oocytes having chromosomal aneuploidies and most structural anomalies originating from sperm. Increasing female age leads to an increased number of chromosomal aberrations due to a prolonged meiotic period. Chromosome analysis of sperm is challenging but methods have been developed, allowing for the evaluation of individual sperm. Understanding gametic chromosomal abnormalities is crucial in assisted reproductive technology, but questions regarding which cases should undergo sperm chromosome analysis and result interpretation need to be addressed.

Summary: Through cytogenetic analysis, numerous meiotic abnormalities were observed in F-1 hybrids between S. officinarum and E. arundinaceus. Genomic in situ hybridization (GISH) confirmed that 96.70% of lagging chromosomes were from E. arundinaceus. Fluorescence in situ hybridization (FISH) using 45S rDNA and 5S rDNA probes showed chromosome loss and unequal chromosomal separation in tetrads.

Summary: In this study, a meiotic cell-cycle controller ZmTDM1 was identified in maize, which plays a crucial role in the termination of the meiotic cell cycle. ZmTDM1 interacts with RING-type E3 ubiquitin ligase and acts as a subunit of the APC/C E3 ubiquitin ligase complex. This study provides insights into the genetic controls underlying the meiotic cell cycle in maize.

Summary: In this study, we found that H3K9 methylation undergoes changes during mitosis in Schizosaccharomyces pombe, and the lack of trimethylation of H3K9 leads to defects in chromosome segregation during mitosis. Additionally, the switch in H3K9 methylation is accompanied by phosphorylation of Clr4.

Summary: Autopolyploidy and allopolyploidy are common in plants, but autopolyploidy has received less attention and its evolutionary consequences are unclear. Using chromosome painting probes and fluorescence in situ hybridization, we studied chromosome behavior in autotetraploid, autooctoploid, and autodecaploid sugarcane clones. All autopolyploid clones exhibited stable diploidized chromosome behavior, with preferential pairing observed between homologous copies of chromosome 8. Sequence variation analysis showed no apparent differences among homologs of chromosome 8. Our results suggest that unknown mechanisms, other than DNA sequence similarity, contribute to stable meiotic behavior in these autopolyploid sugarcane plants.

Summary: This study examined the quantitative proteomics of chromosome-binding proteins (CBPs) in meiotic prophase I (MPI) in mice. The results showed that CBPs exhibited dynamic changes and formed different complexes during MPI. These complexes functioned in different categories and provided evidence for the importance of CBP complexes in MPI.

Summary: CRISPR/Cas9 has revolutionized genetic research by providing a precise tool for sequence editing, and it can also be used to localize proteins at specific genomic locations without nuclease activity. This study utilized CRISPR/Cas9 to investigate the role of kinetochore proteins in suppressing meiotic recombination, shedding light on the mechanism behind this crucial biological process.

Summary: The European fan palm, the only native palm in continental Europe, is facing population decline due to anthropogenic effects including climate change. Genetic variability among natural populations of this palm is scarce, but essential for conservation planning and preventing genetic contamination. In this study, genetic structure in the European fan palm was analyzed using specific genetic markers, revealing lower variability in populations from the eastern half of its distribution. The study also identified two patterns of spread and differentiation, with implications for ecological management and species conservation.
