Maternal RNAs and proteins in the oocyte contribute to early embryonic development. After
fertilization, these maternal factors are cleared and embryonic development is determined …

Maternal‐to‐zygotic transition (MZT) is the critical process for the establishment of
embryonic identity across vertebrates. During this period, the massive transcriptional …

The first wave of transcriptional activation occurs after fertilisation in a species-specific
pattern. Despite its importance to initial embryonic development, the characteristics of …

The phylogenomics and comparative functional genomics of avian species were
investigated in the Bird 10,000 Genomes (B10K) project because of the important …

In animals, the early embryo is mostly transcriptionally silent and development is fueled by
maternally supplied mRNAs and proteins. These maternal products are important not only …

Background The initial stages of development depend on mRNA and proteins accumulated
in the oocyte, and during these stages, certain genes are essential for fertilization, first …

Background The transition from fertilized egg to embryo in chicken requires activation of
hundreds of genes that were mostly inactivated before fertilization, which is accompanied …

During maternal-to-embryonic transition control of embryonic development gradually
switches from maternal RNAs and proteins stored in the oocyte to gene products generated …

Background In birds as in mammals, a genetic switch determines whether the
undifferentiated gonad develops into an ovary or a testis. However, understanding of the …

The early stages of embryonic development in all metazoans are characterized by profound
remodeling of chromatin organization and transcriptomics. This remodeling involves …
