    Stromule extension along microtubules coordinated with actin-mediated anchoring guides perinuclear chloroplast movement during innate immunity

    Amutha Sampath Kumar et al.
    Stromules induced during plant innate immunity dynamically interact and use the cytoskeleton to form and to direct the movement of chloroplasts.

    The Mars1 kinase confers photoprotection through signaling in the chloroplast unfolded protein response

    Karina Perlaza et al.
    A genetic screen in a unicellular photosynthetic organism uncovers the first essential signaling component in the chloroplast unfolded protein response that relays information from the chloroplast to the nuclear compartment.

    Light-dependent single-cell heterogeneity in the chloroplast redox state regulates cell fate in a marine diatom

    Avia Mizrachi et al.
    Single-cell analysis of the chloroplast redox response to high light and oxidative stress revealed light-dependent heterogeneity, and was linked to cell fate determination within isogenic diatom populations.

    Multi-functional roles for the polypeptide transport associated domains of Toc75 in chloroplast protein import

    Yamuna D Paila et al.
    The conserved polypeptide transport associated (POTRA) domains of the protein import channel, Toc75, are essential for protein import into chloroplasts.

    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.

    Proximity proteomics in a marine diatom reveals a putative cell surface-to-chloroplast iron trafficking pathway

    Jernej Turnšek et al.
    An iron-sensitive gene cluster encodes proteins that co-localize with phytotransferrin endosomes and are involved in key intracellular iron transformation and trafficking processes in a model marine diatom.

    Regulation of photosynthetic electron flow on dark to light transition by ferredoxin:NADP(H) oxidoreductase interactions

    Manuela Kramer et al.
    The regulatory switch from protection to assimilation, which plants use to exploit natural, fluctuating light, involves movement of the enzyme ferredoxin:NADP(H) oxidoreductase between chloroplast membrane complexes.
