    Firefly genomes illuminate parallel origins of bioluminescence in beetles

    Timothy R Fallon et al.
    The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

    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.

    The spatial separation of processing and transport functions to the interior and periphery of the Golgi stack

    Hieng Chiong Tie et al.
    Transport machinery localizes at the cisternal rim while modification machinery localizes at the interior.

    Protein sequences bound to mineral surfaces persist into deep time

    Beatrice Demarchi et al.
    A chemically unstable ostrich eggshell peptide survives for at least 3.8 million years at the equator, stabilized by strong mineral interactions.

    The decoration of specialized metabolites influences stylar development

    Jiancai Li et al.
    Regulation of diterpene glycoside malonylation status influences stylar elongation through affecting auxin signaling in Nicotiana attenuata.

    cAMP signaling regulates DNA hydroxymethylation by augmenting the intracellular labile ferrous iron pool

    Vladimir Camarena et al.
    cAMP is identified to play a novel role in regulating DNA demethylation and gene transcription by augmenting the intracellular reactive Fe(II) pool.
