Genes required for visual system wiring.

1Locations according to Drosophila genome sequence Release 4.2.1.2Mapping based on lethality of trans-heterozygous allele combinations.3Mapping based on visual system wiring phenotype in trans-heterozygous combinations or in whole-eye clones.4Rescue of visual system wiring phenotype with a GMR transgene.5Identified mutations, showing allele name followed by predicted amino acid or other mutation (based on PA isoform, unless otherwise indicated).6Previous detailed report of alleles recovered in this screen.7the number indicates the size of the deletions in nucleotides.8Mapped using chromosomal deficiencies.9Mapped using P-element induced male recombination.10Splicing consensus site was mutated which resulted in complete failure of proper splicing.11Based on Genbank protein sequence AAF74192.12splicing donor site was mutated leading to a premature stop before the transmembrane domain Please see ref [20] for the further detail.13Rescue using genomic fragment.14Fails to complement sim embryonic CNS phenotype.
