UAS regulatory sequences drive expression of a short inverted repeat.
The expression of PlodHMS01259 under the control of Scer\GAL4SPARC-MI00329-GAL4 (and Dicer-2, for a more efficient RNAi) in the larval fat body leads to defects in the secretion of collagen IV (Vkg.GFP, but not of Trol (another extracellular matrix component; Trol.GFP). There are no general secretion defects, as shown by the normal patterns of secr.GFP and Vkg.GFP signals.
