The critical role of CDK2 in the progression of meiosis was demonstrated in a single mammalian species, the mouse. We used immunocytochemistry to study the localization of CDK2 during meiosis in seven rodent species that possess hetero- and homomorphic male sex chromosomes. To compa...
involving SUN (Sad1/UNC-84)-domain-containing proteins at the inner nuclear envelope (NE). RPMs remain significantly understudied in plants, with respect to their importance in the regulation of meiosis. Here, we demonstrate thatArabidopsis thalianameiotic centromeres undergo ...
The synaptonemal complex (SC) surface-spreading technique was used to visualize the process of chromosome synapsis in spermatocytes and oocytes of E. talpinus Pallas, 1770, a species with the XX sex chromosome system in both males and females. We used el
aMean square displacement (MSD) curves for the different meiosis stages computed over short tracks (total duration 2 min). Control MSD (somatic centromeres) are shown in Supplementary Fig.3. Error bars: average ± s.e.m. Numbers of tracks: 130 (leptotene), 96 (zygotene), 99 (pachyten...
meiosis, corresponding to the zygotene phase of prophase I (Fig. 2B), whereas chromosomes of the mutant were aberrantly condensed into crescent-like structure (Fig. 2G). In the later stages, in the wild-type, dyads were generated, indicating meiosis I had been completed (Fig. 2C), which...
MeiosispericentromererDNARhoeotranslocationsA study on the organization of prophase I chromatin in a PTH (permanent translocation heterozygosity) plant -Rhoeo spathacea was carried out. The sequential DAPI/AMD-FISH technique showed that nuclear polarization and centromere clustering during preleptotene-pachy...
2.1Prophase Arrest in Meiosis The mammalian oocyte enters its first meioticprophaseduring fetal development, which in mice occurs between embryonic days 12.5 and 13.5 (Kocer, Reichmann, Best, & Adams, 2009; McLaren, 2003; Sánchez & Smitz, 2012). Prophase I is subdivided into the leptotene, zyg...
What's the difference between mitosis and meiosis?Learn more with our side-by-side comparison. Need to review the different parts of the cell and what they do?We walk you through thefunctions of the cell membrane,endoplasmic reticulum, andvacuoles. If you learn better by looking at the big...
FBF-1 and FBF-2 (collectively FBF) are two nearly identical Puf-domain RNA-binding proteins that regulate the switch from mitosis to meiosis in the C. eleg... C Merritt,G Seydoux - 《Development》 被引量: 89发表: 2010年 The Molecular Control of Meiotic Chromosomal Behavior: Events in Ear...
