I'd like to annotate the role of some genes in survival to anoxia - oxygen deprivation (not hypoxia, oxygen reduction).
C.elegans can survive for around 48 hrs with almost no oxygen (see PubMed ), and this requires a specific ceramide synthase hyl-2. Mutants in hyl-2 survive anoxia for much shorter periods, and this correlates with loss of specific ceramides.
I just wondered if GO would consider protection from anoxia to be a "biological process". We already have GO:0034059, "response to anoxia", but this is not quite what I wanted to express (although you would assume that the organism would need to mount a response to anoxia in order to survive anoxia). Here, it's the "base state" of the organism that determines whether it survives and for how long: a lack of hyl-2 makes it more susceptible to anoxia.
Thanks for your insight, Cheers, Alan
