mudIs1 [tph-1p::ChR2::GFP + myo-3p::mCherry]. When tph-1 mutants carrying mudIs1 are exposed to blue light, the worms continue to move rather than stopping like wild-type animals. Reference: Pokala N & Glater EE. 2018. Journal of Undergraduate Neuroscience Education. 162(2): A152-A158.

Isolated by Michael Ailion from rotting apricot from home of Wayne Davis and Danielle Endres in Salt Lake City, Utah, 8/4/2006, under tree on north side of house. Coordinates: 40° 42' 26.16" N, 111° 52' 3.27" W. Animals move very rapidly. Strain started from a single L4 hermaphrodite and grown three generations before freezing. 18S rDNA sequence differs from C. briggsae NCBI entry (PB102), but is identical to the 18S sequence of AF16, HK104, PB800 and VT847. Cross-fertile with AF16.

Mixed "strain" started from many different worms that emerged from the same apricot that gave rise to strain EG4181. Some worms emerged as dauers, but there were also L4s and adults. Consists of a mix of the worms that came from the apricot to try to maintain as much diversity as possible in the population and thus is not a true strain in the traditional sense. It will be sent as contaminated worms since it cannot be cleaned up without going through a bottleneck.

oxIs322 [myo-2p::mCherry::H2B + myo-3p::mCherry::H2B + Cbr-unc-119(+)]. Wild type worms with mCherry fluorescence in pharyngeal and body wall muscle. Visible on dissection microscope at high magnification. Complex transgene insertion in place of Mos1 allele ttTi5605. Useful for following "invisible" insertions at ttTi5605 site by Mos1 Single Copy gene Insertion (MosSCI). Please note: The insertion was a complex event pulling in more than one transgene and parts of the array. Therefore, the exact molecular structure of the insert is not known. Therefore the strain should NOT be used as a control for insert copy number or other detailed molecular controls of MosSCI insertions. Succesfully used as a balancer for the ttTi5605 locus.

Caenorhabditis sp. 9 Male-female strain. Isolated from a sample collected by Joel Ehrenkranz on May 20, 2008, around 11 AM in Shinkolobwe, Katanga Province, Democratic Republic of the Congo (~11°S, 26°E). The sample was collected from worked soil which contained organic material around the foundation of a wattle hut. This time of year was the dry season in Katanga Province, so daytime temperatures were in the high 70s and nighttime temperatures in the low 50s. The specimen was placed in a ziplock bag with a slice of apple for transport to Susan Mango's lab at the Huntsman Cancer Institute, Salt Lake City, Utah. From the date of collection until the specimen reached the lab was approximately 2 weeks.

qqIr7 [peel-1(qq99)] I. oxSi78 [peel-1p::peel-1 (introns included)::GFP::peel-1 3'UTR + Cbr-unc-119(+)] II. Genetic background is a mixture of N2 and wild isolate EG4348. The oxSi78 insertion produces a PEEL-1::GFP translational fusion. PEEL-1::GFP is expressed in the spermatogenic germline and packaged into sperm. PEEL-1::GFP appears to localize to fibrous body-membranous organelles. PEEL-1::GFP does not rescue peel-1(qq99). Reference: Seidel HS, et al. PLoS Biol. 2011 Jul;9(7):e1001115.
