GO:0007377 JSON

germ-band extension

Biological Process

Definition (GO:0007377 GONUTS page)

Elongation of the germ band on the ventral side of the embryo, accompanied by a halving in width. The elongation process pushes the posterior midgut invagination closed and compresses the amnioserosa further.
