Abstract

COVER PHOTOGRAPH: Drosophila embryonic axons visualized for expression of Fasciclin II (red) and a transgene that marks sema-phorin2b-positive cells (green). semaphorin2b-positive axons deviate from their normal Fasciclin II tracts in both the lateral and ventral direction in semaphorin2b mutants (upper right) compared to wildtype (upper left). From Drosophila semaphorin2b is Required for the Axon Guidance of a Subset of Embryonic Neurons, Mark M. Emerson, Jennifer B. Long, and David Van Vactor, Developmental Dynamics 242:861–873, 2013.
