What's a GeneRIF?

These observations establish a CYSL-1, CYSL-2, and RHY-1 dependent mechanism by which animals heritably adapt to infection.
Title: Cysteine synthases CYSL-1 and CYSL-2 mediate C. elegans heritable adaptation to P. vranovensis infection.
CYSL-1 interacts with EGL-9 and activates HIF-1 that upregulates expression of genes detoxifying sulfide and cyanide, the CYSL-2 acts as a cyanoalanine synthase in the cyanide detoxification pathway and simultaneously produces hydrogen sulfide
Title: Biochemical properties of nematode O-acetylserine(thiol)lyase paralogs imply their distinct roles in hydrogen sulfide homeostasis.
Data indicate that genes sqrd-1, ethe-1, cysl-1, cysl-2 and HIF-1 are involved in survival to hydrogen sulfide and hydrogen cyanide.
Title: The response of Caenorhabditis elegans to hydrogen sulfide and hydrogen cyanide.
