In all the Archegoniate fertilization and the first critical phases of embryogeny occur within the shelter provided by the archegonium and the adjacent gametophytic tissue. |
Expression was again up-regulated in early embryogeny and again during germination. |
For example, the significance of the details of embryogeny could well escape the reader more interested in the technicalities of seed production. |
The matter seemed involved in mystery, and no one attempted to raise the veil which hung over the subject of embryogeny. |
At the end of late embryogeny, somatic embryos were already differentiated, and the width of the embryo approximated its length. |
In animals, well-studied examples of the coenocytic state are found in oogenesis and in the early embryogeny of Drosophila. |
