Evoked and spontaneous synaptic transmission are increased in Slob-RNAi flies. (A) Sample EJC traces from two control lines and one Slob-RNAi line. (B) Pooled data. Peak amplitude of EJC is increased significantly when Slob-RNAi is expressed ubiquitously (black bar) compared with controls (white bars). (C) Sample mEJC traces from two control lines and one Slob-RNAi line. (D) Pooled data. Frequency and amplitude of mEJCs are increased significantly in the Slob-RNAi^all line (black bars) compared with controls (white bars). Refer to Materials and methods for the definition of the WT¹ and WT² lines.
