ceIs269 [unc-129p::tomm-20::Venus + unc-129p::mCherry + ttx-3p::RFP]; Integration in Chromosome I (near genetic position -3.20 or 1.14). The ttx-3 marker is quite faint in this strain especially in larvae. The tomm-20::Venus construct was injected at 0.5 ng/ ul in the strain used to make this integrant, so virtually all of the visible tomm-20::Venus signal s associated with mitochondria with essentially no background. The unc-129p::mCherry marker is expressed at a very low level that are detectable only with a sensitive camera (and often not by eye at 1000X). In strains lacking mitochondria in the dorsal cord, use the camera to focus on the mCherry in the dorsal cord, then acquire in the YFP channel.

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).
