The Chromatin Protein DUET/MMD1 Controls Expression of the Meiotic Gene TDM1 during Male Meiosis in Arabidopsis. [PDF]
PLoS Genetics, 2015 Meiosis produces haploid cells essential for sexual reproduction. In yeast, entry into meiosis activates transcription factors which trigger a transcriptional cascade that results in sequential co-expression of early, middle and late meiotic genes ...

Tackling Plant Meiosis: From Model Research to Crop Improvement
Frontiers in Plant Science, 2018 Genetic engineering and traditional plant breeding, which harnesses the natural genetic variation that arises during meiosis, will have key roles to improve crop varieties and thus deliver Food Security in the future. Meiosis, a specialized cell division

m6A modification of a 3′ UTR site reduces RME1 mRNA levels to promote meiosis
Nature Communications, 2019 Ime4p is a yeast N6-methyladenosine (m6A) methyltransferase with an unknown role in meiosis. Rme1p is a repressor of meiosis. Here the authors show that Ime4p methylates RME1 3′ UTR to reduce its expression and enable meiosis, thus providing an example ...

Nature Communications, 2016 Meiosis is a cell division program that produces haploid gametes and is initiated by a retinoic acid-dependent process. Here the authors report that a meiosis-specific protein, MEIOC, is upregulated in a retinoic acid-independent manner and is required ...

The Rice AAA-ATPase OsFIGNL1 Is Essential for Male Meiosis
Frontiers in Plant Science, 2017 Meiosis is crucial in reproduction of plants and ensuring genetic diversity. Although several genes involved in homologous recombination and DNA repair have been reported, their functions in rice (Oryza sativa) male meiosis remain poorly understood. Here,

Chromosome architecture and low cohesion bias acrocentric chromosomes towards aneuploidy during mammalian meiosis. [PDF]
Nat CommunAneuploidy in eggs is a leading cause of miscarriages or viable developmental syndromes. Aneuploidy rates differ between individual chromosomes. For instance, chromosome 21 frequently missegregates, resulting in Down Syndrome.

Two mechanisms drive pronuclear migration in mouse zygotes
Nature Communications, 2021 In a newly fertilized egg, maternal and paternal chromosomes are enclosed in two separate pronuclei but the mechanisms in mammals for pronuclear movement are unclear.

Shugoshin1 may play important roles in separation of homologous chromosomes and sister chromatids during mouse oocyte meiosis. [PDF]
PLoS ONE, 2008 BACKGROUND: Homologous chromosomes separate in meiosis I and sister chromatids separate in meiosis II, generating haploid gametes. To address the question why sister chromatids do not separate in meiosis I, we explored the roles of Shogoshin1 (Sgo1) in ...
