Redistribution of RNA localization in early embryos of zebrafish

ABSTRACT: This study investigates spatial transcriptomic dynamics during early embryogenesis in Danio rerio (zebrafish). Using TOMO-seq, we profiled RNA localization along the animal–vegetal axis at key embryonic stages for 1 hpf (~4-cell), 2 hpf (~64-cell), and 3 hpf (~1000-cell) embryos. Samples were collected in biological triplicates and sectioned into five defined regions (A–E) along the axis to assess spatial distribution. The data were used to analyze maternal RNA localization, transcript stability, and onset of zygotic transcription.

Redistribution of RNA localization in early embryos of rainbow trout

Project description:This study investigates spatial transcriptomic dynamics during early embryogenesis in Oncorhynchus mykiss (rainbow trout), a teleost species with large oocytes and prolonged developmental timing. Using TOMO-seq, we profiled RNA localization along the animal–vegetal axis at key embryonic stages, including 0 hpf (freshly fertilized egg/zygote), 1 hpf (early cleavage stage), 1 dpf (early blastula stage, ~32-64 cells), and 3 dpf (mid-blastula, ~1000 cells). Samples were collected in biological triplicates and sectioned into five defined regions (A–E) along the axis to assess spatial distribution. The data were used to analyze maternal RNA localization, transcript stability, and onset of zygotic transcription. Our results reveal spatially distinct transcriptome changes, highlighting both conserved and species-specific mechanisms relative to other teleosts such as zebrafish.

Redistribution of RNA localization in early embryos of trout hybrid (Oncorhynchus mykiss egg fertilized with Salvelinus fontinalis sperm)

Project description:This study investigates the spatial transcriptomic dynamics during early embryogenesis in a hybrid trout, where the Oncorhynchus mykiss (rainbow trout) egg was fertilized with the Salvelinus fontinalis sperm. Using TOMO-seq, we profiled RNA localization along the animal–vegetal axis at key embryonic stages, 0 hpf (freshly fertilized egg/zygote), 1 hpf (early cleavage stage), 1 dpf (early blastula stage, ~32-64 cells), and 3 dpf (mid-blastula, ~1000 cells). Samples were collected in biological triplicates and sectioned into two sections (A & B) along the axis to assess spatial distribution. The data were used to analyze for de novo transcription by looking for paternal transcripts. Our results revealed spatially distinct transcriptome changes.

RNA_Seq analysis of localization along animal-vegetal axis of Danio rerio

Project description:Asymmetrical localization of biomolecules inside the egg, results in uneven cell division and two daughter cells with different fates. This phenomenon is required for the establishment of many biological processes and is particularly responsible for the great variety of cell types formed during developmentand requires strict timing and positional control. The key molecules determining the body plan are the mRNAs, of which many examples have already been discovered to be asymmetrically localized during oogenesis and embryogenesis in both the amphibian and fish models. However, our knowledge about evolutionary conservation or differences of localized mRNAs is still limited to a few candidates. Our goal has been to compare localization profiles along the animal-vegetal axis of mature eggs of four diverse models, Xenopus laevis, Danio rerio, Ambystoma mexicanum and Acipenser ruthenus using the spatial expression analysis method called TOMO-Seq. Surprisingly, we revealed RNAs that code for many known important genes such as germ layer determinants, germ plasm factors and members of key signalling pathways, are localized in completely different profiles among the models and sometimes even missing in their genomes. We determined the transcriptome distribution and found a poor correlation between the vegetally localized genes but a relatively good correlation between the animally localized genes. These findings indicate that the regulation of embryonic development within the animal kingdom is highly diverse and cannot be deduced based on a single model.

RNA_Seq analysis of localization along animal-vegetal axis of Acipenser ruthenus

Project description:We performed cryosectioning of oocytes along the animal-vegetal axis (first developmental axis, section A (first animal) to section E (last vegetal), followed by RNA-Seq to determine the localization profiles of coding and noncoding RNAs. The method allowed for a complete view on RNA localization. We found that nearly all RNAs are localized, but only a small percentage is actively transported during oogenesis.
