      Phosphorylation of Conserved PIN Motifs Directs Arabidopsis PIN1 Polarity and Auxin Transport
      Fang Huang, Marcelo Kemel Zago, Lindy Abas, Arnoud van Marion, Carlos Samuel Galván-Ampudia, Remko Offringa
      Plant Cell Apr 2010, 22 (4) 1129-1142; DOI: https://doi.org/10.1105/tpc.109.072678

      This work identifies the Ser residues located in three evolutionarily conserved TPRXS(N/S) motifs within the PIN1 auxin efflux carrier hydrophilic loop as substrates of the PINOID kinase. It shows that reversible phosphorylation of these Ser residues by PINOID and possibly other kinases is necessary and sufficient for proper PIN1 polar localization, auxin distribution, and regulated plant development.

      Integrative Transcript and Metabolite Analysis of Nutritionally Enhanced DE-ETIOLATED1 Downregulated Tomato Fruit
      Eugenia M.A. Enfissi, Fredy Barneche, Ikhlak Ahmed, Christiane Lichtlé, Christopher Gerrish, Ryan P. McQuinn, James J. Giovannoni, Enrique Lopez-Juez, Chris Bowler, Peter M. Bramley, Paul D. Fraser
      Plant Cell Apr 2010, 22 (4) 1190-1215; DOI: https://doi.org/10.1105/tpc.110.073866

      The downregulation of DE-ETIOLATED1 (DET1) results in tomato fruits with the simultaneous elevation of multiple nutritional antioxidants. Characterization through the analysis and integration of large-scale metabolomic and transcriptomic data sets reveals a coordinated activation of core metabolic processes underlying DET1 loss of function in developing tomato fruit.

      Plant Cell Apr 2010, 22 (4) 1216-1231; DOI: https://doi.org/10.1105/tpc.110.074088

      This work examines role of sulfite reductase (SiR) in assimilatory reduction of inorganic sulfate to sulfide. Reduced sulfite reductase activity results in growth retardation and severe perturbations of sulfur, nitrogen, and carbon metabolism, demonstrating that, surprisingly, SiR plays a role in controlling flux in the assimilatory sulfate reduction pathway.

      Five Arabidopsis Reticulon Isoforms Share Endoplasmic Reticulum Location, Topology, and Membrane-Shaping Properties
      Imogen Sparkes, Nicholas Tolley, Isabel Aller, Julia Svozil, Anne Osterrieder, Stanley Botchway, Christopher Mueller, Lorenzo Frigerio, Chris Hawes
      Plant Cell Apr 2010, 22 (4) 1333-1343; DOI: https://doi.org/10.1105/tpc.110.074385

      This article describes the localization and organization of several members of a family of proteins known as the reticulons that reside in the membrane of the endoplasmic reticulum (ER), which is responsible for synthesizing proteins for export out of the cell. The reticulons reside in the ER membrane, interact with each other, and induce curvature to make these ER compartments tubular in structure.

      Arrangement of Photosystem II and ATP Synthase in Chloroplast Membranes of Spinach and Pea
      Bertram Daum, Daniela Nicastro, Jotham Austin II, J. Richard McIntosh, Werner Kühlbrandt
      Plant Cell Apr 2010, 22 (4) 1299-1312; DOI: https://doi.org/10.1105/tpc.109.071431

      This work uses electron cryotomography to study the three-dimensional supramolecular organization of photosystem II and ATP synthase within the thylakoid membrane. It finds photosystem II as dimers in grana stacks, whereas ATP synthases are monomers located on minimally curved stromal thylakoids or grana end membranes but are absent from the highly curved grana margins, in clear contrast to the situation in mitochondria.

      Plant Cell Apr 2010, 22 (4) 1143-1160; DOI: https://doi.org/10.1105/tpc.109.067728

      This work examines the interaction between jasmonate (JA) and light signaling. It finds that attenuation of shade responses by low red/far-red light requires the JA signal component COI1 and that some responses to JA are partly dependent on the light signal component phyA. The JA and phyA pathways are integrated through stability of the repressor protein JAZ1.

      Plant Cell Apr 2010, 22 (4) 1299-1312; DOI: https://doi.org/10.1105/tpc.109.071431

      This work uses electron cryotomography to study the three-dimensional supramolecular organization of photosystem II and ATP synthase within the thylakoid membrane. It finds photosystem II as dimers in grana stacks, whereas ATP synthases are monomers located on minimally curved stromal thylakoids or grana end membranes but are absent from the highly curved grana margins, in clear contrast to the situation in mitochondria.

      Plant Cell Apr 2010, 22 (4) 1388-1403; DOI: https://doi.org/10.1105/tpc.109.069666

      The authors imaged fungal transformants secreting fluorescent effector fusion proteins in first-invaded rice cells. Two effectors that accumulated in biotrophic interfacial complexes were translocated into the invaded cell's cytoplasm. Depending on rice cell type and effector size, the translocated effectors moved into adjoining uninvaded rice cells, potentially preparing them for fungal entry.

      Phosphorylation of Conserved PIN Motifs Directs Arabidopsis PIN1 Polarity and Auxin Transport
      Fang Huang, Marcelo Kemel Zago, Lindy Abas, Arnoud van Marion, Carlos Samuel Galván-Ampudia, Remko Offringa
      Plant Cell Apr 2010, 22 (4) 1129-1142; DOI: https://doi.org/10.1105/tpc.109.072678

      This work identifies the Ser residues located in three evolutionarily conserved TPRXS(N/S) motifs within the PIN1 auxin efflux carrier hydrophilic loop as substrates of the PINOID kinase. It shows that reversible phosphorylation of these Ser residues by PINOID and possibly other kinases is necessary and sufficient for proper PIN1 polar localization, auxin distribution, and regulated plant development.

      The authors imaged fungal transformants secreting fluorescent effector fusion proteins in first-invaded rice cells. Two effectors that accumulated in biotrophic interfacial complexes were translocated into the invaded cell's cytoplasm. Depending on rice cell type and effector size, the translocated effectors moved into adjoining uninvaded rice cells, potentially preparing them for fungal entry.

      This article describes the localization and organization of several members of a family of proteins known as the reticulons that reside in the membrane of the endoplasmic reticulum (ER), which is responsible for synthesizing proteins for export out of the cell. The reticulons reside in the ER membrane, interact with each other, and induce curvature to make these ER compartments tubular in structure.

      Plant Cell Apr 2010, 22 (4) 1174-1189; DOI: https://doi.org/10.1105/tpc.109.066647

      The TCP family is a group of plant-specific transcription factors whose DNA binding properties have not been studied in detail. Here, we examine TCP4 by both biochemical and structural analyses to describe the DNA binding mechanisms of this family of proteins and predict a fold that the domain might adopt.

      This work uses electron cryotomography to study the three-dimensional supramolecular organization of photosystem II and ATP synthase within the thylakoid membrane. It finds photosystem II as dimers in grana stacks, whereas ATP synthases are monomers located on minimally curved stromal thylakoids or grana end membranes but are absent from the highly curved grana margins, in clear contrast to the situation in mitochondria.

      This work shows how a specific class of small RNAs respond to auxin and quantitatively regulate root branching, an important adaptive trait in plants. These small RNAs and their target transcription factors form a self-regulatory gene network through multiple feedback loops. This ensures a quantitative control of lateral root development and modulation of auxin effects.

      The authors imaged fungal transformants secreting fluorescent effector fusion proteins in first-invaded rice cells. Two effectors that accumulated in biotrophic interfacial complexes were translocated into the invaded cell's cytoplasm. Depending on rice cell type and effector size, the translocated effectors moved into adjoining uninvaded rice cells, potentially preparing them for fungal entry.

      Using large-scale quantitative analysis, this work reveals that grain shape and size are independent traits in both modern and primitive wheat and are under the control of distinct genetic components. Moreover, the phenotypic diversity in grain morphology found in modern commercial wheat is the result of a recent and severe bottleneck.

      Plant Cell Apr 2010, 22 (4) 1358-1372; DOI: https://doi.org/10.1105/tpc.109.072058

      This work analyzes the surprising result that Nicotiana benthamiana transformed with RNA-dependent RNA polymerase 1 from Nicotiana tabacum (Nt-RDR1) is hypersusceptible to several viruses. It provides evidence supporting a dual role for RDR1 in contributing to salicylic acid–mediated antiviral defense at the same time as it suppresses RDR6-mediated antiviral RNA silencing.

      Cucumber Mosaic Virus Movement Protein Severs Actin Filaments to Increase the Plasmodesmal Size Exclusion Limit in Tobacco
      Shengzhong Su, Zhaohui Liu, Cheng Chen, Yan Zhang, Xu Wang, Lei Zhu, Long Miao, Xue-Chen Wang, Ming Yuan
      Plant Cell Apr 2010, 22 (4) 1373-1387; DOI: https://doi.org/10.1105/tpc.108.064212

      Viral movement proteins (MPs) enable viral pathogens to pass through cell walls by increasing the size exclusion limit (SEL) of plasmodesmata (PD). Cucumber mosaic virus (CMV) MP was found to bind and sever actin filament (F-actin) in vitro, and such severing was required for CMV MP-induced increase in PD SEL.

      Plant Cell Apr 2010, 22 (4) 1232-1248; DOI: https://doi.org/10.1105/tpc.108.065128

      The Arabidopsis histidine kinase CKI1 is essential for female gametogenesis and is able to activate cytokinin signaling by unknown mechanisms. This study shows that CKI1 acts upstream of HISTIDINE PHOSPHOTRANSFER PROTEINS to regulate downstream signaling events in a cytokinin receptor-independent manner and demonstrates that CKI1-AHP signaling is essential for plant growth and development.
