Sex differences in life history drive evolutionary transitions among maternal, paternal, and bi-parental care. by Klug, H, Bonsall, M, Alonzo, S

“…This effect of anisogamy (i.e., the fact that females initially invest more into each individual zygote than males) might help explain the predominance of maternal care in nature and differs from previous work that found no effect of anisogamy on the origin of different sex-specific patterns of care from an ancestral state of no care. …”

Diversity of human and mouse homeobox gene expression in development and adult tissues by Dunwell, T, Holland, P

Inflammatory and anti-inflammatory cytokines in the endometrium of cows during anaphrodisia and estrous cycle by Iryna Bondarenko, Andriy Lazorenko, Yurii Musiienko, Oleksandr Panasenko

“…No significant difference in the level of IL-1 during proestrus compared to the corpus luteum was found, as a result of the extinction of the transient phlogogenic reaction inherent in the oestrous endometrium at this time, due to the cytokine balance, which prepares the best conditions for zygote implantation. It was found that the level of IL-1 during oestrus significantly increases relative to the corpus luteum and proestrus stages. …”

A rare case of NIPT discrepancy caused by the placental mosaicism of three different karyotypes, 47,XXX, 47,XX,+21, and 48,XXX,+21 by Jin Li, Mingshui Xie, Fang Wang, Jianhong Ma, Jiafu Li, Chen Chen, Zhimin Li, Juan Wang, Yuanzhen Zhang, Yirong Li

“…It is speculated that the zygote may have 48,XXX,+21 karyotype and trisomy rescue could be the main mechanism for the development of the homogeneous fetus and complex mosaic placenta. …”

Viability of exogenous stages of development of the causative agent of trichu-riasis of dogs under the influence of temperature by V. Yevstafieva, O. Dolhin

“…The terms of formation of various stages of egg development in embryogenesis depended on the temperature, where as its indicators increased, the terms of these stages also shortened. The term of the zygote stage was shortened from 9 to 6 days, the stage of blastomere splitting – from 12 to 6 days, the leguminous embryo stage – from 15 to 6 days, the tadpole embryo stage – from 21 to 9 days, the larval stage – from 24 to 12 days, formation of a mobile larva – from 27 to 15 days. …”

Aneuploidy in intergeneric crosses between FRAGARIA х ANANASSA DUCH. х POTENTILLA ANSERINA L by S. O. Baturin, E. A. Filipenko

“…Hence, eliminating 14 chromosomes of F. х ananassa and 14 chromosomes of P. anserina during the first divisions of a zygote (2n = 70) should be considered as the most likely scenario for the 2n = 42 chromosome number development in the studied No. 89-3, so the genetic material of P. anserina was absent in the embryo’s somatic cells. …”

Mating-Induced Common and Sex-Specific Behavioral, Transcriptional Changes in the Moth Fall Armyworm (<i>Spodoptera frugiperda</i>, Noctuidae, Lepidoptera) in Laboratory by Ting Wu, Da-Hu Cao, Yu Liu, Hong Yu, Da-Ying Fu, Hui Ye, Jin Xu

“…RNA sequencing in females revealed that there are more reproduction related GO (gene ontology) terms and KEGG (Kyoto encyclopedia of genes and genomes) pathways (mainly related to egg and zygote development) enriched to upregulated DEGs (differentially expressed genes) than to downregulated DEGs at 0 and 24 h postmating. …”

On the causes of gene-body methylation variation in Arabidopsis thaliana. by Rahul Pisupati, Viktoria Nizhynska, Almudena Mollá Morales, Magnus Nordborg

“…In conclusion, we show that genetic and environmental factors can change gbM at a cellular level, and hypothesize that these factors can also lead to transgenerational differences between individuals via the inclusion of such changes in the zygote. If true, this could explain genographic pattern of gbM with selection, and would cast doubt on estimates of epimutation rates from inbred lines in constant environments.…”

<i>Plasmodium falciparum</i> Development from Gametocyte to Oocyst: Insight from Functional Studies by Dinkorma T. Ouologuem, Antoine Dara, Aminatou Kone, Amed Ouattara, Abdoulaye A. Djimde

“…This review outlines the mechanisms involved in <i>Plasmodium falciparum</i> sexual stage development in both the human and mosquito vector, and zygote to oocyst differentiation. Functional studies unravel mechanisms employed by <i>P. falciparum</i> to orchestrate the expression of stage-specific functional products required to succeed in its complex life cycle, thus providing us with potential targets for developing new therapeutics. …”

Modelling the suppression of a malaria vector using a CRISPR-Cas9 gene drive to reduce female fertility by North, AR, Burt, A, Godfray, HCJ

“…The exact level of suppression is influenced by additional fitness costs of the transgene such as the somatic expression of Cas9, and its deposition in sperm or eggs leading to damage to the zygote. In the absence of these costs, or of emergent drive-resistant alleles that restore female fertility, population suppression across the study area is predicted to stabilise at ~&#x2009;95% 4&#xA0;years after releases commence. …”
