Screening for genetic loci affecting the active zone formation in C. elegans.
Objective To screen and identify genetic loci affecting the active zone formation in C. elegans. Methods A SYD-2::GFP reporter was constructed and used as an active zone marker for forward genetic screen to identify genetic loci affecting the active zone formation. Results Eight isolated mutant alleles were characterized from 15,000 haploid genomes. The SYD-2::GFP phenotypes of these mutants are mainly reflected as the changes of number, morphology, distribution of puncta and the gaps appearance. Some mutants also exhibit visible behavioral or physical phenotypes, and aldicarb resistant or sensitive phenotypes. Conclusion These mutants provide the opportunity for further systematic research on the active zone formation and the neurotransmission.
