The rosetteless gene controls development in the choanoflagellate S. rosetta by Tera C Levin, Allison J Greaney, Laura Wetzel, Nicole King

Aneuploidy is frequent in heterozygous diploid and triploid hydatidiform moles by P. Walbum, L. Andreasen, M. Geilswijk, I. Niemann, L. Sunde

“…Each spermatozoon provides one pair of centrioles to the zygote. The presence of two pairs of centrioles may cause an increased risk of aneuploidy.…”

Acne Syndromes and Mosaicism by Sumer Baroud, Jim Wu, Christos C. Zouboulis

“…Abnormal mosaicism is the coexistence of cells with at least two genotypes, by the time of birth, in an individual derived from a single zygote, which leads to a disease phenotype. Somatic mosaicism can be further categorized into segmental mosaicism and nonsegmental somatic mosaicism. …”

Contribution of Massive Mitochondrial Fusion and Subsequent Fission in the Plant Life Cycle to the Integrity of the Mitochondrion and Its Genome by Ray J. Rose

“…MMF occurs at critical times of the life cycle, prior to flowering, in the enlarging zygote and at germination, mixing the cells’ mitochondrial population—the so-called “discontinuous whole”. …”

Micropipette replacement for automated cell micromanipulation by Wijaya, Nico Fendy

“…One of the step in PGD is to change the micropipette in every cycle to avoid cross contamination among different zygote. The objective of this project is to introduce a mechanism to change the pipette and study the advantages and disadvantages of different mechanism that will make up the full automated PGD machine. …”

Minimum requirements for ookinete to oocyst transformation in Plasmodium. by Carter, V, Nacer, A, Underhill, A, Sinden, R, Hurd, H

“…During their passage through a mosquito vector, malaria parasites undergo several developmental transformations including that from a motile zygote, the ookinete, to a sessile oocyst that develops beneath the basal lamina of the midgut epithelium. …”

The XY gene hypothesis of psychosis: origins and current status. by Crow, T

“…As a consequence of the mechanism of meiotic suppression of unpaired chromosomes <msuc> such X-Y gene pairs generate epigenetic variation around a species defining motif that is carried to the zygote with potential to initiate embryonic gene expression in XX or XY format. …”

Imprinting in the endosperm: a possible role in preventing wide hybridization. by Gutierrez-Marcos, J, Pennington, P, Costa, L, Dickinson, H

“…In plants, these strategies involve either pre-zygotic barriers, such as differences in floral structure and pollen-stigma recognition, or post-zygotic barriers, which are less well understood and affect aspects of seed development ranging from fertilization to maturation. …”

Males with high genetic similarity to females sire more offspring in sperm competition in Peron's tree frog Litoria peronii. by Sherman, C, Wapstra, E, Uller, T, Olsson, M

“…We studied relatedness effects on post-copulatory gametic choice and/or sperm competition in an external fertilizer, Peron's tree frog (Litoria peronii), since external fertilizers offer exceptional control in order to test gametic interaction effects on probability of paternity and zygote viability. Sperm competition experiments were done blindly with respect to genetic relatedness among males and females. …”

Genetics and Epigenetics of the X and Y Chromosomes in the Sexual Differentiation of the Brain by Lucas E. Cabrera Zapata, Luis Miguel Garcia-Segura, María Julia Cambiasso, Maria Angeles Arevalo

“…Now we know that the divergent evolutionary process suffered by X and Y chromosomes has determined that they now encode mostly dissimilar genetic information and are subject to different epigenetic regulations, characteristics that together contribute to generate sex differences between XX and XY cells/individuals from the zygote throughout life. Here we will review and discuss relevant data showing how particular X- and Y-linked genes and epigenetic mechanisms controlling their expression and inheritance are involved, along with or independently of gonadal hormones, in the generation of sex differences in the brain.…”

Molecular confirmation of the hybrid origin of Sparganium longifolium (Typhaceae) by Yinjiao Yu, Fengxia Li, Eugeny A. Belyakov, Weidong Yang, Alexander G. Lapirov, Xinwei Xu

“…We also found that all samples of S. longifolium were F1 generations, and thus hypothesized that S. emersum and S. gramineum could likely maintain their species boundary through the post-zygote reproductive isolation mechanism of F1 generation sterility.…”

Controlling contractile instabilities in the actomyosin cortex by Masatoshi Nishikawa, Sundar Ram Naganathan, Frank Jülicher, Stephan W Grill

“…Here, we report that in the Caenorhabditis elegans zygote, feedback between active RhoA and myosin induces a contractile instability in the cortex. …”

Paternal genome rescues mouse preimplantation embryo development in the absence of maternally-recruited EZH2 activity by Huili Wang, Erika E Paulson, Libing Ma, Pablo J Ross, Richard M Schultz

“…To reconcile these differences we propose that the H3K27me3 state present in the zygote needs to be faithfully propagated following DNA replication in at least one pronucleus, otherwise development is compromised.…”

Cortical flow aligns actin filaments to form a furrow by Anne-Cecile Reymann, Fabio Staniscia, Anna Erzberger, Guillaume Salbreux, Stephan W Grill

“…Here, we quantify the dynamical organization of actin filaments at the onset of ring assembly in the C. elegans zygote, and provide a framework for determining emergent actomyosin material parameters by the use of active nematic gel theory. …”

Pheromone Guidance of Polarity Site Movement in Yeast by Katherine C. Jacobs, Daniel J. Lew

“…Spatial gradients of pheromones are decoded to guide mobile polarity sites so that polarity sites in mating partners align towards each other, as a prerequisite for cell-cell fusion and zygote formation. In ascomycetes including <i>S. cerevisiae</i>, one pheromone is prenylated (<b>a</b>-factor) while the other is not (α-factor). …”

Diversity of RNA-Binding Proteins Modulating Post-Transcriptional Regulation of Protein Expression in the Maturing Mammalian Oocyte by Marie Christou-Kent, Magali Dhellemmes, Emeline Lambert, Pierre F. Ray, Christophe Arnoult

“…Therefore, during its growth, the oocyte must produce the mRNA transcripts needed to fulfil its protein requirements during the active period of meiotic completion, fertilisation, and the maternal-to zygote-transition (MZT). After meiotic resumption, gene expression control can be said to be transferred from the nucleus to the cytoplasm, from transcriptional regulation to translational regulation. …”

Natural variation in an ABC transporter gene associated with seed size evolution in tomato species. by Cintia Hotta Orsi, Steven D Tanksley

“…This gene exerts its control on seed size, not through the maternal plant, but rather via gene expression in the developing zygote. Phenotypic effects of allelic variation at Sw4.1 are manifested early in seed development at stages corresponding to the rapid deposition of starch and lipids into the endospermic cells. …”

Male reproductive senescence as a potential source of sexual conflict in a beetle by Carazo, P, Molina-Vila, P, Font, E

“…By imposing direct (i.e., male fertility) or indirect (i.e., zygote viability) reproductive costs to females, male senescence may lead to sexual conflict at different levels. …”
