    Adaptation of hydroxymethylbutenyl diphosphate reductase enables volatile isoprenoid production

    Mareike Bongers et al.
    Differences in HDR product preference present a novel mechanism in plants to control substrate availability for short- and long-chain isoprenoids.

    The return to water in ancestral Xenopus was accompanied by a novel mechanism for producing and shaping vocal signals

    Ursula Kwong-Brown et al.
    When ancestral Xenopus returned to water ~170mya, they evolved a new method for producing courtship calls underwater without airflow, using vibrations that also preserve essential acoustic information on species identity.

    Three ancient hormonal cues co-ordinate shoot branching in a moss

    Yoan Coudert et al.
    The mosses and angiosperms have independently evolved mechanisms that use the same hormones-auxin, cytokinin and strigolactone-to regulate lateral shoot branching.

    Chimeric origins of ochrophytes and haptophytes revealed through an ancient plastid proteome

    Richard G Dorrell et al.
    An in silico reconstruction of a chloroplast that existed hundreds of millions of years ago casts new insights in the evolutionary processes, endosymbioses and chimerism events that shape the origin of plastids.

    Apicomplexan-like parasites are polyphyletic and widely but selectively dependent on cryptic plastid organelles

    Jan Janouškovec et al.
    Apicomplexan-like parasites originated several times independently and many of them contain cryptic plastid organelles, which demonstrate that the parasites evolved from photosynthetic algae.

    Genetic transformation of the dinoflagellate chloroplast

    Isabel C Nimmo et al.
    Successful stable transformation of the dinoflagellate chloroplast genome.

    Thyroid hormone regulates distinct paths to maturation in pigment cell lineages

    Lauren M Saunders et al.
    Single-cell transcriptomics combined with genetic analyses identify post-embryonic neural crest subpopulations and thyroid hormone dependencies in zebrafish adult pigment pattern development.

    Crystal structures of virus-like photosystem I complexes from the mesophilic cyanobacterium Synechocystis PCC 6803

    Yuval Mazor et al.
    The structure of the photosystem I (PSI) complex from Synechocystis is determined, and reaction center subunits engineered to resemble a viral PSI are found to promote promiscuous electron acceptor properties.

    Cilia-mediated Hedgehog signaling controls form and function in the mammalian larynx

    Jacqueline M Tabler et al.
    Genetic studies in mice reveal the molecular and embryological mechanisms of vocal fold development and function, thereby informing our understanding of vocal communication and congenital voice defects.

    Nucleophile sensitivity of Drosophila TRPA1 underlies light-induced feeding deterrence

    Eun Jo Du et al.
    Electron-donating nucleophilic compounds activate TRPA1 ion channels in fruit flies and mosquitoes, but not humans, making TRPA1 a promising target for insect repellants.
