    • The primers 5′-CTAAAGTTAATCATACTCTGG and 5′-ACATTTTTACTTTATCAGTGG were used to amplify a 1-kb fragment that was used to probe a cDNA library in λZap. A full-length 1.5-kb cDNA was sequenced on both strands with the use of overlapping primers.

    • The primers 5′-GCGGCGGATCCAGGAAAATTGGAAGAGCAACCAAG and 5′-GCGGCCTGCAGTTACTTTATTCAGTTGGTTCTATG were used to amplify unc-129 coding region from DNA of ev554, ev557, and ev566 mutants and wild-type animals for sequencing.

    • Axons of DA and DB motorneurons were examined by fluorescence microscopy with the unc-129::gfp reporter pAC12 (5, 23) passed genetically into daf-1 and daf-4 mutants and a newly identified TGF-β receptor mutant (18).

    • A fragment of the unc-129 5′ regulatory region extending 4.8 kb upstream from the initiator methionine codon was amplified by polymerase chain reaction (PCR) from a genomic clone (pAC3) with the primers 5′-CATTTTCTTGCTTGCTCTTCC and T7. Transcriptional reporters were made by inserting the 4.8-kb regulatory region upstream of, and in frame with, the GFP coding sequence contained in vectors pPD95.79 and pPD95.70 (+NLS) to create pAC9 and pAC10, respectively. pAC9 was cut with either Xba I, Sma I, or Bst EII Xba I and religated to generate GFP reporters containing 3 kb (pAC11), 2.5 kb (pAC12), or 3 kb with an internal deletion of 1.2 kb (pAC13) of unc-129 regulatory sequence, respectively (Fig. 3). Extrachromosomal arrays carrying unc-129::gfp reporters were created by standard germline transformation (7) and chromosomally integrated with the protocol described by M. Hamelin, I. M. Scott, J. C. Way, and J. G. Culotti [EMBO J. 11, 2885 (1992)].

    • The neuron-and muscle-specific promoter derivatives express in essentially the same set of cells as full-length promoter derivatives (see text), except for muscle and neurons (plus seam cells), respectively. Neither derivative appears to disrupt embryonic expression. Expression of unc-129(+) from the unc-129 neuron-specific promoter does not rescue motoraxon guidance defects of unc-129 (ev554) (45% DA and DB defects collectively, n = 96), but expression from the muscle-specific promoter does rescue (3% DA and DB defects collectively, n = 88). VD and DD motoraxons are also visibly rescued by expression of unc-129(+) from the muscle-specific promoter (A. Colavita, S. Krishna, H. Zheng, R. W. Padgett, J. G. Culotti, unpublished data).

    • note
    • UNC-129 was HA epitope (YPYDVPDYASL) tagged immediately after residue 291 by use of a PCR-mediated protocol. The tagged gene was subcloned downstream of the myo-3 promoter found in pPD96.52. Extrachromosomal arrays were created by standard germline transformation (7), and immunostaining was performed as described (29).

    • This hypothesis is supported by the identification of a gene that acts upstream of unc-129 to repress its activity in ventral body wall muscle (B. Nash, A. Colavita, J. G. Culotti, unpublished data).

    • Strains carrying unc-5::gfp or unc-40::gfp transgenic arrays were passed genetically into unc-129(ev554). Extrachromosomal arrays carrying unc-6::HA were created by coinjecting pIM97 (14 μg/ml) (29) and carrier plasmid DNA (80 μg/ml) into unc-6(ev400) and unc-129(ev554);unc-6(ev400) hermaphrodites.
