Bacteria. Comamonas sp., a bacterium on which C. elegans grows particularly well. Str-R. DA1877 is derived from a bacterium isolated from soil in the Dallas area by Boris Shtonda in 2002. That strain was called H39 in Avery, L, Shtonda, BB (2003), "Food transport in the C elegans pharynx", J Exp Biol 206: 2441-2457. It was identified as genus Comamonas by 16S rDNA sequencing, as described in the paper. L. Avery isolated a spontaneous streptomycin-resistant variant by selecting for growth in LB broth + 200 ug/ml streptomycin sulfate. This strain, when spread on NGMSR plates, gave rise to faster-growing papillae; one of these was streaked out to get DA1877. Biosafety Level: BSL-1.

Integration into ttTi4348 mosSCI site (I:-5.32). oxIs322 [myo-2p::mCherry::H2B + myo-3p::mCherry::H2B + ? + Cbr-unc-119(+)] III. Nuclear, red fluorescence in pharynx and body wall muscle. Complex integration into ttTi5605 mosSCI site (II:0.77). oxTi81 [eft-3p::GFP::H2B::tbb-2 3'UTR + unc-18(+)] V. Nuclear, green fluorescence is broadly expressed (in most cells). Integration into chr.V: 1.21. Combined fluorescent balancer strain for LG I, LG II and LG V.
