Chiasmate male meiosis in six species of water bugs from infraorders Nepomorpha and Gerromorpha (Insecta: Heteroptera)

open access: yesComparative Cytogenetics, 2009
The type of male meiosis is a stable character at the family level in the order Heteroptera and provides additional information on the relationships between taxa.

Meiosis-specific cohesin component, Stag3 is essential for maintaining centromere chromatid cohesion, and required for DNA repair and synapsis between homologous chromosomes.

open access: yesPLoS Genetics, 2014
Cohesins are important for chromosome structure and chromosome segregation during mitosis and meiosis. Cohesins are composed of two structural maintenance of chromosomes (SMC1-SMC3) proteins that form a V-shaped heterodimer structure, which is bridged by

Recent advances in understanding of meiosis initiation and the apomictic pathway in plants

open access: yesFrontiers in Plant Science, 2014
Meiosis, a specialized cell division to produce haploid cells, marks the transition from a sporophytic to a gametophytic generation in the life cycle of plants.

Meiosis-specific gene discovery in plants: RNA-Seq applied to isolated Arabidopsis male meiocytes

open access: yesBMC Plant Biology, 2010
Background Meiosis is a critical process in the reproduction and life cycle of flowering plants in which homologous chromosomes pair, synapse, recombine and segregate. Understanding meiosis will not only advance our knowledge of the mechanisms of genetic

Retinoic acid-induced CYP51 nuclear translocation promotes meiosis prophase I process and is correlated to the expression of REC8 and STAG3 in mice

open access: yesBiology Open, 2018
Lanosterol 14 α-demethylase (CYP51) plays a crucial role in cholesterol biosynthesis. In gamete development, CYP51 is involved in initiating meiosis resumption in oocytes through its product, meiosis activating sterol (MAS).

Eliminating separase inhibition reveals absence of robust cohesin protection in oocyte metaphase II

open access: yesThe EMBO Journal
The meiotic segregation pattern to generate haploid gametes is mediated by step-wise cohesion removal by separase, first from chromosome arms in meiosis I, and then from the pericentromere in meiosis II.

m6A modification of a 3′ UTR site reduces RME1 mRNA levels to promote meiosis

open access: yesNature 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 ...

Qualitative rather than quantitative phosphoregulation shapes the end of meiosis I in budding yeast

open access: yesThe EMBO Journal
Exit from mitosis is brought about by dramatic changes in the phosphoproteome landscape. A drop in Cyclin-dependent kinase (Cdk) activity, the master regulatory kinase, and activation of counteracting phosphatases such as Cdc14 in budding yeast, results ...

Meiotic mutat томату controlling exit from meiosis

open access: yesФактори експериментальної еволюції організмів, 2013
Aims. This paper presents the results of cytological and genetic analysis of new meiotic mutant of tomato (Lycopersicon esculentum Mill.). Methods. Studies on meiosis in microsporogenesis were made in iron-acetocarmine smears of anther fixed in acetic ...

METTL16 is Required for Meiotic Sex Chromosome Inactivation and DSB Formation and Recombination during Male Meiosis

open access: yesAdvanced Science
Meiosis in males is a critical process that ensures complete spermatogenesis and genetic diversity. However, the key regulators involved in this process and the underlying molecular mechanisms remain unclear.
