    A multifaceted analysis reveals two distinct phases of chloroplast biogenesis during de-etiolation in Arabidopsis

    Rosa Pipitone et al.
    Serial-Block-Face Scanning Electron Microscopy (SBF-SEM) associated with biomolecular analysis show that chloroplast differentiation proceeds by distinct ‘structure establishment’ and ‘chloroplast proliferation’ phases, each with differential protein and lipid regulation.

    Overall energy conversion efficiency of a photosynthetic vesicle

    Melih Sener et al.
    The overall energy conversion efficiency is calculated for a bacterial vesicle that harvests solar energy for ATP production on the basis of an atomic-detail structural model.

    Algal-fungal symbiosis leads to photosynthetic mycelium

    Zhi-Yan Du et al.
    The capacity for symbiosis between photosynthetic microalgae and early diverging lineages fungi was demonstrated with microscopy and stable isotope exchange of carbon and nitrogen.

    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.

    The Arabidopsis transcription factor ABIG1 relays ABA signaled growth inhibition and drought induced senescence

    Tie Liu et al.
    Arabidopsis plants slow growth and jettison leaves in response to drought via a mechanism that involves the transcription factor ABIG1.

    Recurring patterns in bacterioplankton dynamics during coastal spring algae blooms

    Hanno Teeling et al.
    Dynamic successive blooms of clades of planktonic marine bacteria that can be observed during blooms of marine algae follow discernible patterns, part of which might be explained by substrate-induced forcing.

    Photosynthetic sea slugs induce protective changes to the light reactions of the chloroplasts they steal from algae

    Vesa Havurinne, Esa Tyystjärvi
    Slug chloroplasts avoid damage to photosynthesis by maintaining an oxidized electron transfer chain with the help of oxygen-sensitive electron acceptors.

    Structural insights into the light-driven auto-assembly process of the water-oxidizing Mn4CaO5-cluster in photosystem II

    Miao Zhang et al.
    The structures of photosystem II, with the water-oxidizing Mn4CaO5-cluster fully removed and in an intermediate assembly state, show that photoassembly is facilitated by perfectly pre-arranged protein ligands of the five metal ions.

    The genome and phenome of the green alga Chloroidium sp. UTEX 3007 reveal adaptive traits for desert acclimatization

    David R Nelson et al.
    Euryhaline green algae utilise intracellular osmoprotectant modulation and specialised redox enzyme networks to successfully inhabit a desert coastline.

    The GluTR-binding protein is the heme-binding factor for feedback control of glutamyl-tRNA reductase

    Andreas S Richter et al.
    Heme-dependent feedback inhibition of rate-limiting ALA-synthesis of plant tetrapyrrole biosynthesis depends on binding of heme to glutamyl-tRNA reductase-binding protein.
