The paper compares DNA methylation dynamics in medaka and zebrafish embryos, showing conserved remodelling patterns without global erasure, and identifies conserved non-canonical methylation reprogramming.

The paper identifies specific amino acid residues and N-glycosylation patterns in Bouncer proteins that mediate species-specific sperm-egg compatibility between medaka and zebrafish.

This paper introduces SCON, a short conditional intron for conditional knockout via one-step zygote injection, showing its function across vertebrate species.

This study shows that DCST1 and DCST2 are essential for sperm-egg fusion in mice and zebrafish, with mutations leading to male infertility.

This study uses reciprocal zebrafish-medaka hybrids to show that maternal factors primarily control the timing of zygotic genome activation.

The paper identifies maternally-deposited antisense piRNAs that silence transposons in zebrafish embryos by targeting young LTR retrotransposons and promoting H3K9me2/3 modification.

This study identifies Bouncer, a Ly6/uPAR protein in zebrafish oocytes, as essential for species-specific fertilization and shows it can enable cross-species fertilization between zebrafish and medaka.
