Egg Cell-Secreted EC1 Triggers Sperm Cell Activation During Double Fertilization
Stefanie Sprunck,Svenja Rademacher,Frank Vogler,Jacqueline Gheyselinck,Ueli Grossniklaus,Thomas Dresselhaus +5 more
TL;DR: Gamete interactions in Arabidopsis depend on small cysteine-rich EC1 (EGG CELL 1) proteins accumulating in storage vesicles of the egg cell and that are released during sperm-egg interaction, providing evidence that mutual gamete activation, regulated exocytosis, and sperm plasma membrane modifications govern flowering plant gamete interactions.
Journal ArticleDOI
Zygotic Resetting of the HISTONE 3 Variant Repertoire Participates in Epigenetic Reprogramming in Arabidopsis
Mathieu Ingouff,Svenja Rademacher,Sarah Holec,Lucija Šoljić,Nie Xin,Anne Readshaw,Shi Hui Foo,Benoît Lahouze,Stefanie Sprunck,Frédéric Berger +9 more
TL;DR: The results suggest that reprogramming of parental genomes in the zygote limits the inheritance of epigenetic information carried by H3 variants across generations.
Journal ArticleDOI
A General G1/S-Phase Cell-Cycle Control Module in the Flowering Plant Arabidopsis thaliana

TL;DR: This work has identified a regulatory cascade controlling entry into S phase in the flowering plant Arabidopsis thaliana that can give rise to hysteresis highlighting the here identified dosage sensitivity of CDK inhibitors in this network.
Journal ArticleDOI
Downregulation of egg cell-secreted EC1 is accompanied with delayed gamete fusion and polytubey
TL;DR: It is found that some sperm cells are able to fuse with the female gametes even 2 to 3 days after pollination, as reflected by delayed embryo and endosperm development, and by polytubey.
