“…It is likely that worms in their natural habitat may have access to much greater amounts of iron than those provided for them in the lab via a diet of E. coli on an agar surface. If C. elegans does use magnetite to build its own magnetic field detector, it is possible that enrichment of the lab culture conditions may result in increased magnetic indices for adults, or even succeed in enabling larval stage worms to perform this behavior better than what we previously reported ( Bainbridge et al, 2016 ). While we consider this experiment informative, we do not agree with Landler et al, 2018 in their suggestion that ingestion of magnetic particles might confer the ability to migrate within magnetic fields to C. elegans .…”

“…The three thermosensory rGCs GCY-8, GCY-18, and GCY-23, as well as the TAX-2 and TAX-4 cGMP-gated channels are required for the response of AFD to magnetic fields (Vidal-Gadea et al 2015), suggesting that the signal is amplified and transduced via the cGMP second messenger. The identity of the magnetoreceptor in AFD is unknown, but both the cilia and microvilli located at the sensory endings of AFD are required for C. elegans to orient correctly in a magnetic field (Bainbridge et al 2016). It has been posited that iron particles localized to the microvilli and/or in the surrounding glia may be directly associated with the membrane or transmembrane mechanosensory channels (Clites and Pierce 2017).…”
