    Evolutionary Developmental Biology: Sensing oxygen inside and out

    Maria R Stupnikov, Wellington V Cardoso
    Neuroendocrine cells act as oxygen sensors in animals from fish to humans, but the evolutionary origins of these cells are only just becoming clear.

    The last common ancestor of animals lacked the HIF pathway and respired in low-oxygen environments

    Daniel B Mills et al.
    Sponges and ctenophores lack hypoxia-inducible factors, suggesting that the metazoan last common ancestor could have lived aerobically under severe hypoxia and did not need to regulate its transcription in response to oxygen availability.

    Aerotaxis in the closest relatives of animals

    Julius B Kirkegaard et al.
    The colony-forming choanoflagellate Salpingoeca rosetta is capable of moving towards oxygen using logarithmic sensing of oxygen concentrations and a navigation strategy that involves random movements.

    Blue light-induced LOV domain dimerization enhances the affinity of Aureochrome 1a for its target DNA sequence

    Udo Heintz, Ilme Schlichting
    Light absorption by the algal transcription factor Aureochrome 1a causes dimerization at the light-oxygen-voltage (LOV) sensing domain, which has implications for the design of synthetic photoreceptors for optogenetics.
