    The induction of pyrenoid synthesis by hyperoxia and its implications for the natural diversity of photosynthetic responses in Chlamydomonas

    Peter Neofotis et al.
    The algal pyrenoid is formed at high O2 levels, even when CO2 is high, implying that a product of photosynthesis, most likely H2O2 acts as a signal.

    Photosynthesis: Oxygen overload

    Britta Foerster
    A structure that helps algae photosynthesize when carbon dioxide levels are low may also play a role during hyperoxia conditions.

    Expression of a CO2-permeable aquaporin enhances mesophyll conductance in the C4 species Setaria viridis

    Maria Ermakova et al.
    The SiPIP2;7 aquaporin is a functional CO2 pore that can be used to improve CO2 diffusion at the interface between the airspace and leaf mesophyll which limits C4 photosynthesis.

    Functional diversification gave rise to allelic specialization in a rice NLR immune receptor pair

    Juan Carlos De la Concepcion et al.
    Biochemical and in planta studies reveal how a rice immune receptor pair has coevolved to deliver immune responses, an important step towards understanding and engineering bespoke resistance to crop pathogens that threaten food security.

    Control of Arabidopsis shoot stem cell homeostasis by two antagonistic CLE peptide signalling pathways

    Jenia Schlegel et al.
    Plant meristem size and shape is controlled by two intertwined regional feedback signals that are mediated by secreted peptides.

    A novel bivalent chromatin associates with rapid induction of camalexin biosynthesis genes in response to a pathogen signal in Arabidopsis

    Kangmei Zhao et al.
    A previously uncharacterized type of bivalent chromatin plays an important role controlling the timely induction of genes involved in making a potent defense metabolite upon a pathogen signal in Arabidopsis.

    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.

    Members of the ELMOD protein family specify formation of distinct aperture domains on the Arabidopsis pollen surface

    Yuan Zhou et al.
    Pollen aperture patterning in Arabidopsis is controlled by members of the ELMOD protein family, whose expression levels in developing pollen lineage are tightly regulated.

    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.
