In sexually reproducing organisms, life begins with the fusion of transcriptionally silent
gametes, the oocyte and sperm. Although initiation of transcription in the embryo, known as …

The onset of metazoan development requires that two terminally differentiated germ cells, a
sperm and an oocyte, become reprogrammed to the totipotent embryo, which can …

The early embryo of the cockroach Blattella germanica exhibits high E93 expression. In
general, E93 triggers adult morphogenesis during postembryonic development. Here we …

The zygote has a daunting task ahead of itself; it must develop from a single cell (fertilized
egg) into a fully functioning adult with a multitude of different cell types. In the beginning, the …

In hemimetabolan insects, the transcription factor Broad complex (Br–C) promotes wing
growth and development during the nymphal period. We wondered whether Br–C could …

The gene products that drive early development are critical for setting up developmental
trajectories in all animals. The earliest stages of development are fueled by maternally …

Zinc finger protein (Zelda) of Tribolium castaneum (TcZelda) has been showed to play
pivotal roles in embryonic development and metamorphosis. However, the regulatory …

Embryonic dorsal-ventral (DV) patterning by Bone Morphogenetic Proteins (BMPs) is a
conserved feature of Bilateria, based on graded BMP activity set up by diffusible BMP …

Zinc finger protein (Zelda) of Tribolium castaneum (TcZelda) has been showed to play
pivotal roles in embryonic development and metamorphosis. However, the regulatory …

Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for
studying its embryogenesis due to difficulties in removing its rigid chorion and achieving …
