Construct: A heat shock promoter drives expression of a truncated form of sog that includes the CR1 domain plus another 114 amino acids (and contains an additional 33 amino acids derived from vector sequences at the C-terminus).
Expression of sogsupersog1.hs from stage 8 using heat shock results in a reduced number of neurons in the dorsal and lateral peripheral nervous system. Approximately 20% of the embryos fail to undergo dorsal closure.
The number of amnioserosa cells is normal in embryos expressing 4 copies of sogsupersog1.hs.
sogsupersog1.hs is a suppressor | partially of amnioserosa phenotype of tsgunspecified
tsgunspecified embryos lack amnioserosa cells. This phenotype is partially rescued by the expression of sogsupersog1.hs.
sogsupersog1.hs partially rescues sogunspecified
Partially rescues the reduction in the number of amnioserosa cells seen in sogunspecified embryos.
