Fig. 2. Babo regulates axon pruning and axon growth independently.
Drosophila MB neurons misexpressing DN babo (A),
DN babo plus EcR-B1 (B), or DN babo plus
RhoGEF2 (C). Additional images
(A',B',C') indicate the corresponding
Fas2-positive (magenta in A,B,C) axon projections. Note the β lobe
overextensions (open red arrowheads) present in A and B, but absent in C, and
the axon pruning phenotypes (open white arrowheads highlight the aberrant
-dorsal and medial branches), which are visible in A' and
C', but absent in B'. Cell body sections were removed from C to
clearly show MB axons. Scale bar: 20 µm.
