Table 3 Quantitative analysis of axon extension defects in unc-69(lf), unc-76(lf) and other mutants

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

  1. All animals scored had kyIs140 (Pstr-2::gfp) in the background, which turns on its expression in only one of the two AWC neurons (1 AWCON) in wild-type animals. In axon guidance mutants, Pstr-2::gfp expression is silenced in both AWCs (2 AWCOFF) owing to failure of axonal contact. All unc-69 and unc-76 alleles except unc-76(rh116) are arranged in order according to their physical position (5' to 3') in the open reading frame. n, number of animals scored.
