   Tuning self-renewal in the Arabidopsis stomatal lineage by hormone and nutrient regulation of asymmetric cell division

   Yan Gong et al.

   Quantitative live-cell time-lapse imaging reveals that the spatial and temporal degree of cortical polarity domains reflects stem-cell division capacity in cells of the Arabidopsis plant leaf epidermis.

   Uncovering a novel function of the CCR4-NOT complex in phytochrome A-mediated light signalling in plants

   Philipp Schwenk et al.

   The light-activated plant photoreceptor phytochrome A binds to NOT9B to displace it from the CCR4-NOT complex, thereby de-repressing light signalling.

   SABRE populates ER domains essential for cell plate maturation and cell expansion influencing cell and tissue patterning

   Xiaohang Cheng, Magdalena Bezanilla

   SABRE, which is present in a wide range of eukaryotes, localizes to ER subdomains in plants, impacting cell expansion and callose deposition during cell plate maturation.

   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.

   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.

   Epigenetic reprogramming rewires transcription during the alternation of generations in Arabidopsis

   Michael Borg et al.

   Epigenetic reprogramming of the distinct repressive marks H3K27me3 or H3K9me2 guides the transition between the haploid and diploid life forms that encompass the life cycle of land plants.

   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.

   The Arabidopsis active demethylase ROS1 cis-regulates defence genes by erasing DNA methylation at promoter-regulatory regions

   Thierry Halter et al.

   Active DNA demethylation at some defence gene promoters is causal for DNA binding of WRKY transcription factors as well as for transcriptional activation of these genes during plant immune response.

    A fungal member of the Arabidopsis thaliana phyllosphere antagonizes Albugo laibachii via a GH25 lysozyme

    Katharina Eitzen et al.

    A basidiomycete yeast closely related to fungal smuts is an antagonistic microbe in the Arabidopsis leaf phyllosphere that inhibits infection by Albugo laibachii via a GH25 hydrolase with lysozyme activity.
