ARS dynamics in live third instar larvae. (A–H) GFP images of the ARSs taken at distinct time intervals (in minutes) of the nerve cord of third instar larvae immobilized between two coverslips carrying the moesin-GFP under Moody-Gal4. The arrows and arrowheads indicate to the same ARSs at the different time points. I and J are images of live larvae carrying Nrg-GFP and Lifeact-Ruby driven by Moody-Gal4. An Nrg loop and the ARS associated with it, labeled with Lifeact-Ruby, are indicated (empty arrowheads).
