DOI: 10.1002/jcp.27510
Abstract: Intersectins (ITSNs) have been shown to act as adaptor proteins that govern multiple cellular events via regulating Cdc42 activity. However, it remains to be determined whether the ITSN‐Cdc42 pathway is functional in porcine oocytes. To… read more here.

DOI: 10.1002/jcp.30885
Abstract: Mammalian oocytes are arrested at the diplotene stage of prophase I during fetal or postnatal development. It was reported that cyclin‐dependent kinases (CDK1) was the sole CDK to drive the resumption of meiosis and CDK2… read more here.

DOI: 10.1002/mrd.23682
Abstract: Meiosis, a key step in spermatogenesis, is affected by many factors. Current studies have shown that long noncoding RNAs (lncRNAs) are potential factors regulating meiosis, and their regulatory mechanisms have received much attention. However, little… read more here.

DOI: 10.1007/978-1-4939-9818-0_26
Abstract: Determining when a barley plant starts and finishes meiosis is not trivial as when the spikelets undergo meiosis, the spike is not visible as it is still well within the leaf sheath on the developing… read more here.

OsMND1 regulates early meiosis and improves the seed set rate in polyploid rice

DOI: 10.1007/s10725-019-00476-4
Abstract: The meiotic processes of most polyploid rice (Oryza sativa) are genetically abnormal, leading to low pollen fertility, which results in low seed set rates. Some polyploid meiosis stability (PMeS) lines with high seed set rates… read more here.

DOI: 10.1007/s10811-019-01863-0
Abstract: A crossing experiment between two artificial pigmentation mutants of Pyropia suborbiculata (Bangiophyceae, Rhodophyta) was carried out, by which we confirmed when the meiotic phase occurred in its life cycle. Moreover, the early development and morphogenesis… read more here.

DOI: 10.1007/s12275-019-8541-9
Abstract: During meiosis, crossing over allows for the exchange of genes between homologous chromosomes, enabling their segregation and leading to genetic variation in the resulting gametes. Spo11, a topoisomerase-like protein expressed in eukaryotes, and diverse accessory… read more here.

Meiosis: The Origins of Bias

DOI: 10.1016/j.cub.2017.10.055
Abstract: 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… read more here.

Abstract: A universal feature of early oocyte differentiation is formation of the Balbiani body (Bb), a large granule of specific mRNAs, proteins, and organelles. The zebrafish Bb establishes oocyte animal-vegetal polarity by specifying the oocyte vegetal… read more here.

DOI: 10.1016/j.tcb.2016.09.002
Abstract: Eggs and sperm develop through a specialized cell division called meiosis. During meiosis, the number of chromosomes is reduced by two sequential divisions in preparation for fertilization. In human female meiosis, chromosomes frequently segregate incorrectly,… read more here.

Maternal age-dependent APC/C-mediated decrease in securin causes premature sister chromatid separation in meiosis II
Sign Up to like & getrecommendations! Published in 2017 at "Nature Communications"
DOI: 10.1038/ncomms15346
Abstract: Sister chromatid attachment during meiosis II (MII) is maintained by securin-mediated inhibition of separase. In maternal ageing, oocytes show increased inter-sister kinetochore distance and premature sister chromatid separation (PSCS), suggesting aberrant separase activity. Here, we… read more here.
