Table 2 Axon outgrowth and guidance defects of HSN, DD/VD, ALA and AVK neurons

From: The short coiled-coil domain-containing protein UNC-69 cooperates with UNC-76 to regulate axonal outgrowth and normal presynaptic organization in Caenorhabditis elegans

Axon guidance phenotype Defect in unc-69(e587) mutants (%) n
   Ventral outgrowth 16 70
   Midline crossover (HSNL) 38 40
   Failure to reach nerve ring 99 59
   Dorsal outgrowth 33 45
   Premature termination 67 30
   Premature termination or crossover 85 20
  1. The morphology of HSN neurons was visualized using antibodies against serotonin; that of DD/VD neurons using antibodies against GABA; and that of ALA and AVKR neurons using antibodies against FMRF-amide. See Materials and methods for details. n, number of animals scored.
