Worm Plasmids and Resources

The nematode Caenorhabditis elegans (C. elegans or “the worm”) is widely used as a genetic model organism due to their rapid life cycle (3 days from egg to adult) and easy lab maintenance. Worms are particularly well suited for studies in cell biology, development, and aging. Scientists can knock down genes by feeding worms bacteria expressing dsRNA or use CRISPR/Cas9 gene editing to easily engineer specific transgenic worm lines. The transparent body of the C. elegans hermaphrodite consists of 959 somatic cells, which makes them attractive for imaging and fluorescence microscopy experiments. The C. elegans genome is well studied and hundreds of reporters have been developed and characterized which allow researchers to express desired constructs in precise cell types and/or developmental timeframes. Here we highlight some of the plasmids and tools available at Addgene for use in worms.

Plasmid Tools for Use in Worms

The table below highlights plasmids that contain tools for use in worm research. This includes CRISPR, RNAi, empty backbones, fluorescent proteins, and Cre expression plasmids. Large collections or kits are described below and not included in this table. For a more complete list of plasmids that can be used in worms, search Addgene's entire collection.

Plasmid Kits and Collections

Kits are sets of plasmids intended for use together (e.g. cloning and expression systems) and therefore supplied as one item. Collections are plasmids grouped by a specific topic, but can only be ordered individually.


Mos1 Based Transgenesis

  • miniMos Transgenesis Kit - Erik Jorgensen Lab. This kit contains 29 plasmids used to generate transgenic nematodes, including C. elegans and C. briggsae.
    • Other related miniMos plasmids can be found on the Jorgensen Lab page.
  • More information on miniMos and MosSCI plasmids can be found on Christian Frøkjær-Jensen's Wormbuilder website.

General Tools

  • Fire Lab C. elegans Vector Kit - Andrew Fire Lab. A set of vectors for C. elegans research, including lacZ and GFP fusion vectors.
  • C. elegans optimized fluorophores - Andrew Fire Lab. Available with and without PATC, which diminishes epigenetic silencing in the germline.
  • A "FLP-Out" system for controlled gene expression in Caenorhabditis elegans. - Jane Hubbard Lab. Plasmids for the temporal and spatial control of gene expression in C. elegans by combining expression of the FLP recombinase from either a heat-shock promoter or a tissue-specific promoter and expression of the target FLP-out cassette from either a ubiquitous or a tissue-specific promoter.
  • cGAL and Split cGAL plasmids - Paul Sternberg Lab. Plasmids for the temperature-robust GAL4-UAS system in C. elegans.
