Although Pygo expressed ubiquitously in the embryo, it expressed at relatively high level in pre-blastoderm embryos which indicated a high degree of maternally provided message, followed by a low level of ubiquitous zygotic expression.

Results shows that the earlier the treatment starts, the more the decrease of gsc expression in late blastula, the fewer the number of somites at 24 h, and the more severe the defects in axial mesoderm. This suggests that maternal TGF-βsignals are activated immediately after fertilization and such activation continues before the onset of zygotic gene expression.
