Molecular Biology of the Cell, 2012 A minisymposium at the 2011 meeting of the American Society for Cell Biology presented recent advances in the field of meiosis and oogenesis (Figure 1). FIGURE 1: Scheme of meiosis in mouse oocytes. Homologous chromosome pairing, synapsis, and recombination take place in prophase I.

Advanced Science, EarlyView.Based on a well‐established in vitro directed differentiation model and an integrated analysis of high‐density cell lineage trees (CLTs) and single‐cell transcriptomes, it is demonstrated that many subclones are formed by sub‐CLTs resembling each other in terms of both cell type compositions and topological structures.

Tetrahymena meiosis: Simple yet ingenious.
PLoS Genetics, 2021 The presence of meiosis, which is a conserved component of sexual reproduction, across organisms from all eukaryotic kingdoms, strongly argues that sex is a primordial feature of eukaryotes.

The Morphological, Behavioral, and Transcriptomic Life Cycle of Anthrobots
Advanced Science, EarlyView.DNA is thought to determine shape, behavior, and lifespan, with developmental plasticity reserved for stem cells, embryos, and species like amphibia. How much morphogenetic plasticity do adult somatic human cells exhibit? Anthrobots are a self‐organizing, motile synthetic living construct made of genetically normal human epithelial cells.

Mek1 Down Regulates Rad51 Activity during Yeast Meiosis by Phosphorylation of Hed1
PLoS Genetics, 2016 During meiosis, programmed double strand breaks (DSBs) are repaired preferentially between homologs to generate crossovers that promote proper chromosome segregation at Meiosis I.

Advanced Science, EarlyView.Researchers develop advanced tools to study grapevine traits like berry quality and stress resilience. A 200K SNP array and high‐throughput phenotyping enable the identification of loci linked to berry shape, sugar content, acidity, and cold tolerance. Functional validation of genes such as NAC08 reveals roles in cold tolerance.

Sexual Dimorphism in Mouse Meiosis
Frontiers in Cell and Developmental Biology, 2021 Meiosis is a highly conserved and essential process in gametogenesis in sexually reproducing organisms. However, there are substantial sex-specific differences within individual species with respect to meiosis-related chromatin reorganization ...

ALDH1A1 provides a source of meiosis-inducing retinoic acid in mouse fetal ovaries
Nature Communications, 2016 Substantial evidence exists that during fetal ovarian development in mammals, retinoic acid (RA) induces germ cells to express the pre-meiotic marker Stra8 and enter meiosis, and that these effects are prevented in the fetal testis by the RA-degrading ...

Meiosis: The Origins of Bias [PDF]
Current Biology, 2017 Biased, or non-Mendelian, segregation is frequently observed but not well understood. Two recent studies on a specific type of biased segregation in mammalian meiosis suggest that it arises from centromeric satellite expansion and asymmetric modification of microtubules in the oocyte spindle.
