This supports the idea that in embryos from wild-type mothers, dpp H~- mutations cause the transformation of dorsal into ven-tral epidermis. If tissue determined to become dorsal epidermis dies in the dpp rim-null embryos, then one should not see ventral or lateral tissue formed in the double-mutant combination.
Cells on the dorsal surface roll over the edge of the dorsal lip and into the interior of the embryo, a process called involution.a homeo domain transcription factor express ed in the dorsal lip of the blastopore; may be a key factor is specifying these cells as the organ izer of the embryo.(Its name is derived from the two Drosophila home domain proteins to which its homoeo domain is similar: gooseberry and bicoid).ells on the dorsal surface roll over the edge of the dorsal lip and into the interior of the embryo, a process called involution.
