Statement
Reference

A combination of -1.6 to -1.0 of thesna promoter ("VA element") plus the region from -0.25 to -0.10 kb ("augmentation element" AE)from which twi binding sites 1 and 2 are deleted drives EcollacZ expression in a sporadic patternin the ventralmost region of the nuclear cycle 14 embryo.
