Expression of CRE recombinase in the mesoblast lineage driven by the hlh-8 promoter. heSi143 rescues fzr-1(ku298). fzr-1 will be excised upon mesoblast-specific expression of CRE, creating a mesoblast specific mutant of fzr-1. This recombination event can be visualized by a switch from red to green in those cells (the mesoblast) were fzr-1 is lost. Reference: Ruijtenberg S & van den Heuvel S.

SV1450 C. elegans unc-119(ed3) III; heIs145 IV Show Description

Maintain at 15-25C. heIs145 expresses a read-out construct used to visualize CRE activity and specificity, and to test whether CRE expression is likely to induce loss of a gene of interest (tagBFP in this case) in a given tissue. Expression of CRE will result in a change from mCherry to GFP and loss of tagBFP expression in those cells where CRE is active. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.
SV1461 C. elegans unc-119(ed3) III; heSi148 X. Show Description

SV1578 C. elegans unc-119(ed3) III; heIs105 IV; swsn-1(os22) heSi164 V; heSi141 X. Show Description
heIs105 [rps-27::loxP::NLS::mCherry::let858 UTR::loxP::NLS::GFP::let-858 UTR + unc-119(+)] IV. heSi164 [rps-27::loxN::NLS::mCherry::let858 UTR::swsn-1p::swsn-1::unc-54 UTR::loxN::NLS::GFP::let-858 UTR + unc-119(+)] V. heSi141 [hlh-8(short)::FLAG::CRE::tbb-2 + unc-119(+)] X. Maintain the line at 15C and shift to 25C for mutant analysis. Expression of CRE recombinase in the mesoblast lineage driven by the hlh-8 promoter. heSi164 carries a swsn-1 rescue construct which ensures rescue of the temperature-sensitive swsn-1(os22) mutation. Upon expression of CRE (in this case in the mesoblast lineage) the swsn-1 gene will be excised, creating a mesoblast specific mutant of swsn-1. This recombination event can be visualized by a switch from red to green in those mesoblast cells in which swsn-1 was lost. The animals are healthy at 15C, but embryonic lethal and larval arrested at 23-25C. swsn-1(os22) causes mild overproliferation in the mesoblast lineage. The swsn-1 rescuing transgene is unable to rescue germline development of swsn-1(os22) mutants. Reference: Ruijtenberg S & van den Heuvel S. Cell. 2015 Jul 16;162(2):300-13.

TBD307 C.elegans dhc-1(he255[epdz::mCherry::dhc-1]) I; utdSi51 II. Show Description
utdSi51[mex-5p::tomm-20(aa 1-55)::halotag::lov::tbb-2 3’UTR] II. Maintain at 23C and protect from light. Strain is sickly, seems to grow best and lay more eggs at 23C. Upon stimulation with 488nm light, the LOV-ePDZ optogenetic system will recruit mitochondria to the dynein heavy chain in the worm embryo. Embryonic cell divisions can be stopped by if mitochondrial recruitment is stimulated in early development. Room light can also induce mitochondria re-localization and cause infertility; store this strain in the dark. Reference: Fan X, et al. G3 (accepted).
