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

    Richard G Dorrell, Gillian Gile ... Chris Bowler
    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.

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

    Rosa Pipitone, Simona Eicke ... Emilie Demarsy
    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.

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

    Samuel James Watson, Na Li ... R Paul Jarvis
    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.

    Towards novel herbicide modes of action by inhibiting lysine biosynthesis in plants

    Tatiana P Soares da Costa, Cody J Hall ... Matthew A Perugini
    Proof-of-principle for a new herbicide mode of action through the identification of novel inhibitors of lysine biosynthesis with in planta efficacy.

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

    Yamuna D Paila, Lynn GL Richardson ... Danny J Schnell
    The conserved polypeptide transport associated (POTRA) domains of the protein import channel, Toc75, are essential for protein import into chloroplasts.

    A cis-carotene derived apocarotenoid regulates etioplast and chloroplast development

    Christopher I Cazzonelli, Xin Hou ... Barry J Pogson
    Carotenoids are not just required as core components for plastid biogenesis, they can be cleaved into an apocarotenoid signal that regulates etioplast and chloroplast development during extended periods of darkness.

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

    Amutha Sampath Kumar, Eunsook Park ... Jeffrey Lewis Caplan
    Stromules induced during plant innate immunity dynamically interact and use the cytoskeleton to form and to direct the movement of chloroplasts.

    A new synthetic biology approach allows transfer of an entire metabolic pathway from a medicinal plant to a biomass crop

    Paulina Fuentes, Fei Zhou ... Ralph Bock
    A combination of chloroplast transformation with nuclear transformation and large-scale metabolic screening of supertransformed plant lines has enabled an entire biochemical pathway to be transferred from a medicinal plant to a high-biomass crop.

    Autophagosome development and chloroplast segmentation occur synchronously for piecemeal degradation of chloroplasts

    Masanori Izumi, Sakuya Nakamura ... Shinya Hagihara
    A plant autophagy pathway transports chloroplast stroma and envelope components into the vacuole through the division and encapsulation of the site of chloroplasts that is associated with developing autophagosome.

    Chromerid genomes reveal the evolutionary path from photosynthetic algae to obligate intracellular parasites

    Yong H Woo, Hifzur Ansari ... Arnab Pain
    Analysis of chromerid algal genomes reveals how apicomplexans have evolved from free-living algae into successful eukaryotic parasites via massive losses and re-inventing functional roles of genes.
