Analysis of Human Uniparental Embryonic Stem Cells Reveals New Putative Imprinted Loci
Cell Proliferation, EarlyView.To identify novel imprinted genes, parthenogenetic, androgenetic and biparental human embryonic stem cells and their differentiated neural progenitors were analysed by methylome and transcriptome profiling. This approach uncovered 12 putative novel imprinted genes, including a clustered region on chromosome 19, expanding the current catalogue of ...

Strategies for the evolution of sex [PDF]
, 2001 We find that the hypothesis made by Jan, Stauffer and Moseley [Theory in Biosc., 119, 166 (2000)] for the evolution of sex, namely a strategy devised to escape extinction due to too many deleterious mutations, is sufficient but not necessary for the ...

Evolution and comparative ecology of parthenogenesis in haplodiploid arthropods
Evolution Letters, 2017 Changes from sexual reproduction to female‐producing parthenogenesis (thelytoky) have great evolutionary and ecological consequences, but how many times parthenogenesis evolved in different animal taxa is unknown. We present the first exhaustive database

Environmental stress influences reproductive success in male spider mites
Ecological Entomology, EarlyView.This experiment explores how male juvenile food stress impacts reproductive traits in the haplodiploid spider mite Tetranychus urticae. Males exposed to juvenile food stress had lower reproductive success and females mated to these males also suffered reduced fitness as they were not able to produce optimal offspring sex ratios. The negative effects of

Change in gene expression of mouse embryonic stem cells derived from parthenogenetic activation [PDF]
, 2017 BACKGROUND We previously established parthenogenetic mouse embryonic stem cells (ESCs) and this study was subsequently conducted for elucidating the influence of oocyte parthenogenesis on gene expression profile of ESCs.

Role of AMPK Throughout Meiotic Maturation in the Mouse Oocyte: Evidence for Promotion of Polar Body Formation and Suppression of Premature Activation [PDF]
, 2010 This study was conducted to assess the role of AMPK in regulating meiosis in mouse oocytes from the germinal vesicle stage to metaphase II. Exposure of mouse cumulus cell-enclosed oocytes (CEO) and denuded oocytes (DO) during spontaneous maturation in ...

Ecological Entomology, EarlyView.Using multiple infected and uninfected Drosophila sturtevanti lines, we investigated (i) the impact of Wolbachia on fecundity and (ii) its effects relative to antibiotic treatment. Based on over 1680 dissected ovaries, fecundity was similar between infected and uninfected flies.

\u3ci\u3eLongitarsus Melanurus\u3c/i\u3e (Coleoptera: Chrysomelidae) Reproduces on \u3ci\u3eOnosmodium Molle\u3c/i\u3e (Boraginaceae) [PDF]
, 2018 (excerpt) Longitarsus melanurus (Melsheimer) was first associated with Onosmodium Michx. by Popenoe (1877) in Kansas where the sole species is O. molle Michx. (Great Plains Flora Assn. 1986).
