    SUMOylation contributes to proteostasis of the chloroplast protein import receptor TOC159 during early development

    Sonia Accossato et al.
    SUMOylation contributes to the fine-tuning of the proteostatic equilibrium of essential chloroplast protein import receptor TOC159 at early plant development.

    Crosstalk between the chloroplast protein import and SUMO systems revealed through genetic and molecular investigation in Arabidopsis

    Samuel James Watson et al.
    The small ubiquitin-like modifier system directly regulates components of the chloroplast protein import apparatus, that is, TOC proteins, to control chloroplast biogenesis and plant development.

    Deep evolutionary origin of gamete-directed zygote activation by KNOX/BELL transcription factors in green plants

    Tetsuya Hisanaga et al.
    Gamete-derived three-amino-acid-loop-extension homeodomain proteins activate zygote development in a strikingly similar manner between basal land plants and green algae, indicating an ancestral role of these transcription factors in green plants.

    Gamete expression of TALE class HD genes activates the diploid sporophyte program in Marchantia polymorpha

    Tom Dierschke et al.
    The ancestral mechanism to activate diploid gene expression via homeodomain transcription factors was retained in liverworts, an early diverging land plant lineage, and subsequently co-opted during evolution of the diploid sporophyte body.

    Widespread variation in heat tolerance and symbiont load are associated with growth tradeoffs in the coral Acropora hyacinthus in Palau

    Brendan Cornwell et al.
    Bleaching-resistant corals are widespread across Palau and concentrated in warmer regions, but this trait is associated with decreased growth which could lead to reduced fitness if it is the only priority of conservation efforts.

    In situ cryo-ET structure of phycobilisome–photosystem II supercomplex from red alga

    Meijing Li et al.
    The nature of the phycobilisome–photosystem II supercomplex on the native thylakoid determined with cryo-electron tomography at an unprecedented resolution reveals that one phycobilisome interconnects with six photosystem monomers.

    The structure of photosystem I from a high-light-tolerant cyanobacteria

    Zachary Dobson et al.
    The necessity of studying extremophile organisms is exemplified by the structure of photosystem I from a high-light tolerant cyanobacteria, demonstrating the relationship between the structure and function in photosystem I.

    Developing a multivariate prediction model of antibody features associated with protection of malaria-infected pregnant women from placental malaria

    Elizabeth H Aitken et al.
    Machine learning identified six protective antibody features and showed for the first time that serological markers can predict protection from placental-malaria, which is important for evaluation and development of vaccines.

    The effect of host community functional traits on plant disease risk varies along an elevational gradient

    Fletcher W Halliday et al.
    Environmental gradients can modify a fundamental relationship between host community structure and disease, with implications for predicting disease risk in a changing world.

    Chloroplast acquisition without the gene transfer in kleptoplastic sea slugs, Plakobranchus ocellatus

    Taro Maeda et al.
    The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.
