Figure 3. — PRC1 and PRC2 are required for maintenance of dendritic arbors in class IV da neurons. (A,B) Live imaging of an individual wild-type (wt) ddaC neuron at 72 h (A) or 96 h (B) AEL. (C,D) Live imaging of an individual esc²¹ mutant ddaC neuron at 72 h (C) or 96 h (D) AEL. Bar, 50 μm. (E–G) Live imaging of a wild-type MARCM clone at 72 (E) or 96 h (F) AEL. (G) The trace shows branches that have grown (green) or retracted (red) in the interval. Clone genotype: w, Gal4^elav, UAS-mCD8∷GFP/+; Frt2A/Frt2A. Bar, 50 μm. (H–J) Live imaging of a Pc-MARCM clone at 72 h (H) or 96 h (I) AEL. (J) The trace shows branches that have grown (green) or retracted (red) in the interval. Clone genotype: w, Gal4^elav, UAS-mCD8∷GFP/+; Pc ^XT109 Frt2A/Pc^XT109 Frt2A. Bar, 50 μm. (K–N) Increased retraction and reduced growth of terminal dendrites in esc mutants. (K,L) Time-lapse imaging of an individual wild-type ddaC neuron at 96 h AEL (K) and following a 30-min time lapse (L). White arrows denote instances of dendrite growth, and red arrows denote instances of dendrite retraction. (M,N) Time-lapse imaging of an individual esc²¹ mutant ddaC neuron at 96 h AEL (M) and following a 30-min time lapse (N).
