Another key player in mesoderm formation is VegT, a maternally and zygotically expressed transcription inducer localized in the vegetal hemisphere.
2.
The other important function of the gradients of Bicoid, Hunchback, and Caudal proteins is in the transcriptional regulation of other zygotically expressed proteins.
3.
However, in contrary, others also think that mosaicism could be developed post-zygotically and hence may not be a result of mitotic instability.
4.
Much of his research has focused on " zygotically " active genes because he believes the temporal and spatial pattern of their transcription may provide the triggers controlling the normal sequence of embryonic development.
