Abstract (sommario):

Abstract STUDY QUESTION Are variants of genes involved in meiosis initiation responsible for premature ovarian insufficiency (POI)? SUMMARY ANSWER A MEIOSIN variant participates in the pathogenesis of human POI by impairing meiosis due to insufficient transcriptional activation of essential meiotic genes. WHAT IS KNOWN ALREADY Meiosis is the key event for the establishment of the ovarian reserve, and several gene defects impairing meiotic homologous recombination have been found to contribute to the pathogenesis of POI. Although STRA8 and MEIOISN variants have been found to associate with POI

Abstract (sommario):

We have cloned and sequenced the promoter of a meiotin-1 gene, and have determined the precise temporal and spatial pattern of meiotin-1 gene expression. The expression of the meiotin-1 gene is controlled in two increments. The meiotin-1 gene is not expressed in any of the vegetative tissues examined. Early in microsporogenesis, low levels of meiotin-1 RNA can be detected. At the onset of meiosis, there is a dramatic increase in meiotin-1 RNA levels in both tapetal and meiotic cells. However, while meiotin-1 RNA is observed in both the nucleus and cytoplasm of meiotic cells, it is found only i

Abstract (sommario):

Abstract A multicopy plasmid was isolated from a yeast genomic library, whose presence resulted in a twofold increase in meiotic nondisjunction of chromosome III. The plasmid contains a 7.5-kb insert from the middle of the right arm of chromosome III, including the gene THR4. Using chromosomal fragments derived from chromosome III, we determined that the cloned region caused a significant, specific, cis-acting increase in chromosome III nondisjunction in the first meiotic division. The plasmid containing this segment exhibited high spontaneous meiotic integration into chromosome III (in 2.4% o

Abstract (sommario):

In most eukaryotic organisms, chiasmata, the connections formed between homologous chromosomes as a consequence of crossing over, are important for ensuring that the homologues move away from each other at meiosis I. Some organisms have the capacity to partition the rare homologues that have failed to experience reciprocal recombination. The yeast Saccharomyces cerevisiae is able to correctly partition achiasmate homologues with low fidelity by a mechanism that is largely unknown. It is possible to test which parameters affect the ability of achiasmate chromosomes to segregate by constructing

We have used nonessential circular minichromosomes to monitor sister chromatid exchange during yeast meiosis. Genetic analysis shows that a 64-kb circular minichromosome undergoes sister chromatid exchange during 40% of meioses. This frequency is not reduced by the presence of a homologous linear minichromosome. Furthermore, sister chromatid exchange can be stimulated by the presence of a 12-kb ARG4 DNA fragment, which contains initiation sites for meiotic gene conversion. Using physical analysis, we have directly identified a product of sister chromatid exchange: a head-to-tail dimer form of

Abstract (sommario):

In many eukaryotes, disruption of the spindle checkpoint protein Mad2 results in an increase in meiosis I nondisjunction, suggesting that Mad2 has a conserved role in ensuring faithful chromosome segregation in meiosis. To characterize the meiotic function of Mad2, we analyzed individual budding yeast cells undergoing meiosis. We find that Mad2 sets the duration of meiosis I by regulating the activity of APCCdc20. In the absence of Mad2, most cells undergo both meiotic divisions, but securin, a substrate of the APC/C, is degraded prematurely, and prometaphase I/metaphase I is accelerated. Some

Abstract (sommario):

In Drosophila, normal female meiosis arrests at metaphase I. After meiotic arrest is released by egg activation, the two meiotic divisions are rapidly completed, even in unfertilized eggs. Since little is known about the regulation of the meiotic cell cycle after the meiotic arrest, we screened for mutants that arrest in meiosis. Here we describe the phenotype of eggs laid by sterile mothers mutant for either grauzone or cortex. These eggs arrest in metaphase of meiosis II, and although they can enter into an aberrant anaphase II, they never exit meiosis. Prolonged sister-chromatid cohesion is

Abstract Although the physiological meaning of the high potential of mouse embryonic stem cells (ESCs) for meiotic entry is not understood, a rigid safeguarding system is required to prevent ectopic onset of meiosis. PRC1.6, a non-canonical PRC1, is known for its suppression of precocious and ectopic meiotic onset in germ cells and ESCs, respectively. MGA, a scaffolding component of PRC1.6, bears two distinct DNA-binding domains termed bHLHZ and T-box. However, it is unclear how this feature contributes to the functions of PRC1.6. Here, we demonstrated that both domains repress distinct sets o

Abstract (sommario):

In meiosis I, two chromatids move to each spindle pole. Then, in meiosis II, the two are distributed, one to each future gamete. This requires that meiosis I chromosomes attach to the spindle differently than meiosis II chromosomes and that they regulate chromosome cohesion differently. We investigated whether the information that dictates the division type of the chromosome comes from the whole cell, the spindle, or the chromosome itself. Also, we determined when chromosomes can switch from meiosis I behavior to meiosis II behavior. We used a micromanipulation needle to fuse grasshopper sperm

The production of germ cells is an essential process in all sexually reproducing eukaryotes. During male meiosis, four haploid sperm cells are formed from one primary spermatocyte, thereby undergoing two consecutive cell divisions after only one round of chromosome duplication. This process was studied in the nematode Caenorhabditis elegans, as this model organism offers a number of experimental advantages to simultaneously analyze spindle dynamics and ultrastructure.

Abstract (sommario):

Meiosis is a specialized cell division that produces haploid gametes from a diploid progenitor cell. It consists of one round of DNA replication followed by two consecutive rounds of chromosome segregation. Homologous chromosomes segregate in meiosis I and sister chromatids segregate in meiosis II. Failure to correctly regulate meiosis can result in aneuploidy, where daughter cells inherit an incorrect number of chromosomes. Aneuploidy is usually poorly tolerated in eukaryotes, and is associated with infertility, miscarriages and birth defects. At the meiosis I to meiosis II transition, DNA re

Abstract (sommario):

In vertebrate oocytes, meiotic progression is driven by the sequential translational activation of maternal messenger RNAs stored in the cytoplasm. This activation is mainly induced by the cytoplasmic elongation of their poly(A) tails, which is mediated by the cytoplasmic polyadenylation element (CPE) present in their 3’ untranslated regions (3´ UTRs). Sequential, phase-specific translation of these maternal mRNAs is required to complete the two meiotic divisions. Although the earlier polyadenylation events in prophase I and metaphase I are driven by the CPE-binding protein 1 (CPEB1), 90% of t

Abstract (sommario):

Missegregation of chromosomes during meiosis leads to formation of aneuploid eggs. Estimates suggest that in humans, about 10-30% of fertilised eggs and one-third of all miscarriages are aneuploid. Accurate chromosome segregation depends on the coordination between stepwise cohesion resolution and attachments of homologous chromosomes through kinetochores to microtubules, emanating from opposite poles of the cell. The Spindle Assembly Checkpoint (SAC) monitors microtubule-kinetochore attachments and prevents resolution of cohesin complexes by inhibiting the ubiquitin ligase APC/Ccdc2o until al

We report in vivo functions of the only meiosis-specific STAG component of cohesin, STAG3. Newly generated STAG3-deficient mice of both sexes are sterile with meiotic arrest. In these mice, meiotic chromosome architecture is severely disrupted as no bona fide axial elements (AE) form and homologous chromosomes do not synapse. Axial element protein SYCP3 forms dot-like structures, many partially overlapping with centromeres. Asynapsis marker HORMAD1 is

Malgré leur importance, et un large excès de précurseurs moléculaires, le nombre de CO est très limité dans la grande majorité des espèces (Typiquement 1 à 4 par paire de chromosomes).

Abstract (sommario):

Chiasma is the point of crossing over or site where the exchange of genetic material takes place between two homologous, non-sister chromatids. The crossover occurs in the pachytene stage, however, it is observed in the diplotene stage of meiosis-I[2]. The cross-over between the two homologs also creates a new combination of parental genes, forming recombinants. The recombination of the genes causes variation in the population and exert a profound effect on genomic diversity and evolution.

Abstract (sommario):

Meiotic recombination is a process in which homologous chromosomes engage in the exchange of DNA segments, creating gametes with new genetic makeup and progeny with new traits. The genetic diversity generated in this way is the main engine of crop improvement in sexually reproducing plants. Understanding regulation of this process, particularly the regulation of the rate and location of recombination events, and devising ways of modifying them, was the major motivation of this project. The project was carried out in maize and wheat, two leading crops, in which any advance in the breeder’s tool

Abstract (sommario):

The main goal of the proposed research was to continue the mutual investigations into the molecular basis of CMS and male fertility restoration [MRF], with the ultimate goal of understanding these phenomena in higher plants. The experiments focused on: (1) dissecting apart the complex CMS - specific mitochondrial S-Pcf locus, in order to distinguish its essential parts which cause sterility from other parts and study its molecular evolution. (2) Studying the expression of the various regions of the S-Pcf locus in fertile and sterile lines and comparing the structure and ultrastructure of steri

Abstract (sommario):

Territórios Indígenas (TIs) na Amazônia protegem aproximadamente 24.5 gigatoneladas de carbono (GtC) acima do solo, atuam como barreiras significativas contra o desmatamento e a degradação florestal, e funcionam como importantes amortecedores contra as mudanças climáticas. TIs demarcadas apresentam desmatamento significativamente menor do que terras não reconhecidas oficialmente, demonstrando a importância de se demarcar TIs tanto para proteger os meios de subsistência e as culturas dos povos nativos da Amazônia, quanto para conservar suas florestas e rios.
