    ECS1 and ECS2 suppress polyspermy and the formation of haploid plants by promoting double fertilization

    Yanbo Mao, Thomas Nakel ... Rita Groß-Hardt
    The endopeptidases ECS1 and ECS2 regulate double fertilization and their modulation is a powerful tool for the induction of haploids and the formation of triparental plants, which are two agronomically relevant breeding targets.

    Dynamic F-actin movement is essential for fertilization in Arabidopsis thaliana

    Tomokazu Kawashima, Daisuke Maruyama ... Frédéric Berger
    The movement of F-actin filaments, which is regulated by actin-myosin interactions together with a female gamete-specific Rho-GTPase, enables migration of the Arabidopsis sperm cell nucleus towards the female nucleus; which might account for the loss of centrosomes in flowering plants.

    TMEM95 is a sperm membrane protein essential for mammalian fertilization

    Ismael Lamas-Toranzo, Julieta G Hamze ... Pablo Bermejo-Álvarez
    TMEM95, a protein localized to the sperm acrosome cap, is essential for fertilization.

    Controlling fertilization and cAMP signaling in sperm by optogenetics

    Vera Jansen, Luis Alvarez ... Dagmar Wachten
    Optogenetics is a non-invasive way to study cAMP signaling in sperm cells, which is able to control sperm motility and fertilization.

    Murine blastocysts generated by in vitro fertilization show increased Warburg metabolism and altered lactate production

    Seok Hee Lee, Xiaowei Liu ... Paolo F Rinaudo
    In vitro fertilization-conceived murine embryos show evidence of oxidative and metabolic stress with alteration in lactic acid metabolism.

    Specific sensory neurons and insulin-like peptides modulate food type-dependent oogenesis and fertilization in Caenorhabditis elegans

    Shashwat Mishra, Mohamed Dabaja ... Joy Alcedo
    On different bacterial diets, which also serve as different environments for Caenorhabditis elegans, specific sensory neurons and insulin-like peptides integrate food-derived signals to modulate oocyte biology, and hence reproduction.

    Zygotic gene activation in the chicken occurs in two waves, the first involving only maternally derived genes

    Young Sun Hwang, Minseok Seo ... Jae Yong Han
    In Aves, the first wave of transcription is derived exclusively from the maternal genome.

    Genomic adaptations in information processing underpin trophic strategy in a whole-ecosystem nutrient enrichment experiment

    Jordan G Okie, Amisha T Poret-Peterson ... James J Elser
    Trait-based metagenomic analysis of an ecosystem fertilization experiment shows that genomic traits that affect the costs and rates of biochemical information-processing mediate community assembly.

    Maternal LSD1/KDM1A is an essential regulator of chromatin and transcription landscapes during zygotic genome activation

    Katia Ancelin, Laurène Syx ... Edith Heard
    The maternally provided histone demethylase LSD1/KDM1A has an instrumental role at the beginning of life, shaping the histone methylation landscape and the transcriptional repertoire of the early mouse embryo.

    Indirect sexual selection drives rapid sperm protein evolution in abalone

    Damien Beau Wilburn, Lisa M Tuttle ... Willie J Swanson
    An NMR-based structural study of sperm proteins reveals a novel protein packaging/dispersion system embedded in a coevolutionary arms race.
