UASt regulatory sequences drive expression of a mutated form of SuUR (amino acid replacements F816S and F817D).
female sterile, with Scer\GAL4c323
embryonic/larval salivary gland, with Scer\GAL4AB1
Expression of SuURCmut.Scer\UAS under the control of Scer\GAL4AB1 results in a dramatic reduction in the size of larval salivary gland nuclei compared to controls.
