Abstract
The major axon tracts in the embryonic CNS of Drosophila are organised in a simple, ladder-like pattern. Each neuromere contains two commissures which connect the contra-lateral sides and two longitudinal connectives which connect the different neuromeres along the anterior-posterior axis. The commissures form in close association with only few cells located at the CNS midline. The formation of longitudinal connectives depends in part on the presence of specific lateral glial cells. To unravel the genes underlying the formation of the embryonic CNS axon pattern, we conducted a saturating F2 EMS mutagenesis, screening for mutations, which disrupt this process. The analyses of the identified mutations lead to a simple sequential model on axon pattern formation in embryonic CNS.
