Insights into the identification and evolutionary conservation of key genes in the transcriptional circuits of meiosis initiation and commitment in budding yeast

open access: yesFEBS Open Bio, 2023
Initiation of meiosis in budding yeast does not commit the cells for meiosis. Thus, two distinct signaling cascades may differentially regulate meiosis initiation and commitment in budding yeast.

Causal Inference in Genetic Trio Studies [PDF]

open access: yesProc. Natl. Acad. Sci. U.S.A. 177 (2020) 24117-24126, 2020
We introduce a method to rigorously draw causal inferences---inferences immune to all possible confounding---from genetic data that include parents and offspring. Causal conclusions are possible with these data because the natural randomness in meiosis can be viewed as a high-dimensional randomized experiment.

Spermatogenesis: The Commitment to Meiosis.

open access: yesPhysiological Reviews, 2016
Mammalian spermatogenesis requires a stem cell pool, a period of amplification of cell numbers, the completion of reduction division to haploid cells (meiosis), and the morphological transformation of the haploid cells into spermatozoa (spermiogenesis ...

MeiosisOnline: A Manually Curated Database for Tracking and Predicting Genes Associated With Meiosis

open access: yesFrontiers in Cell and Developmental Biology, 2021
Meiosis, an essential step in gametogenesis, is the key event in sexually reproducing organisms. Thousands of genes have been reported to be involved in meiosis. Therefore, a specialist database is much needed for scientists to know about the function of

Imaging plant germline differentiation within Arabidopsis flowers by light sheet microscopy [PDF]

open access: yes, 2020
In higher plants, germline differentiation occurs during a relatively short period within developing flowers. Understanding of the mechanisms that govern germline differentiation lags behind other plant developmental processes.

Recombination, Pairing, and Synapsis of Homologs during Meiosis.

open access: yesCold Spring Harbor Perspectives in Biology, 2015
Recombination is a prominent feature of meiosis in which it plays an important role in increasing genetic diversity during inheritance. Additionally, in most organisms, recombination also plays mechanical roles in chromosomal processes, most notably to ...

Homolog pairing during meiosis : dyneins on the move [PDF]

open access: yes, 2010
Meiosis is a specialized form of cell division that generates haploid gametes from diploid cells. This is achieved by having 1 round of DNA replication followed by 2 rounds of nuclear division.

Cohesin-interacting protein WAPL-1 regulates meiotic chromosome structure and cohesion by antagonizing specific cohesin complexes

open access: yeseLife, 2016
Wapl induces cohesin dissociation from DNA throughout the mitotic cell cycle, modulating sister chromatid cohesion and higher-order chromatin structure.

Sexual-lineage-specific DNA methylation regulates meiosis in Arabidopsis

open access: yesNature Genetics, 2018
DNA methylation regulates eukaryotic gene expression and is extensively reprogrammed during animal development. However, whether developmental methylation reprogramming during the sporophytic life cycle of flowering plants regulates genes is presently ...

LSD1 is essential for oocyte meiotic progression by regulating CDC25B expression in mice [PDF]

open access: yes, 2015
Mammalian oocytes are arrested at prophase I until puberty when hormonal signals induce the resumption of meiosis I and progression to meiosis II.
