      The Chlorella variabilis NC64A Genome Reveals Adaptation to Photosymbiosis, Coevolution with Viruses, and Cryptic Sex
      Guillaume Blanc, Garry Duncan, Irina Agarkova, Mark Borodovsky, James Gurnon, Alan Kuo, Erika Lindquist, Susan Lucas, Jasmyn Pangilinan, Juergen Polle, Asaf Salamov, Astrid Terry, Takashi Yamada, David D. Dunigan, Igor V. Grigoriev, Jean-Michel Claverie, James L. Van Etten
      Plant Cell Sep 2010, 22 (9) 2943-2955; DOI: https://doi.org/10.1105/tpc.110.076406

      This report describes the genome sequence of Chlorella variabilis NC64A. Surprisingly, given that NC64A has been thought to be asexual and nonmotile, this work identifies homologs of genes involved in meiosis, gamete fusion, and flagella.

      Distinct Roles of the ATR Kinase and the Mre11-Rad50-Nbs1 Complex in the Maintenance of Chromosomal Stability in Arabidopsis
      Simon Amiard, Cyril Charbonnel, Elisabeth Allain, Annie Depeiges, Charles I. White, Maria Eugenia Gallego
      Plant Cell Sep 2010, 22 (9) 3020-3033; DOI: https://doi.org/10.1105/tpc.110.078527

      DNA damage signaling of chromosomal DNA breaks is of primary importance for initiation of repair and, thus, for global genomic stability. This work confirms that the signaling of double-strand damage is conserved in plants and provides evidence for key roles of the MRN complex and ATR in assuring proper DNA replication in the absence of exogenously induced DNA damage.

      Structural Insights into Maize Viviparous14, a Key Enzyme in the Biosynthesis of the Phytohormone Abscisic Acid
      Simon A.J. Messing, Sandra B. Gabelli, Ignacia Echeverria, Jonathan T. Vogel, Jiahn Chou Guan, Bao Cai Tan, Harry J. Klee, Donald R. McCarty, L. Mario Amzel
      Plant Cell Sep 2010, 22 (9) 2970-2980; DOI: https://doi.org/10.1105/tpc.110.074815

      The structure of maize VP14, a key oxidative enzyme in abscisic acid biosynthesis, provides a framework for understanding the mechanism of this important enzyme. Furthermore, the structure provides a template for the regio- and stereospecificity of VP14 as well as of other plant carotenoid cleavage dioxygenases.

      Plant Cell Sep 2010, 22 (9) 3177-3187; DOI: https://doi.org/10.1105/tpc.110.078048

      This work characterizes infection of rice roots by Magnaporthe oryzae, a fungus that adopts a hemibiotrophic lifestyle during rice shoot infection. Unexpectedly, the cytological and molecular results reveal a largely biotrophic fungal lifestyle in roots, thus indicating that M. oryzae adopts tissue-specific invasion strategies that are accompanied by discrete host responses.

      Plant Cell Sep 2010, 22 (9) 2999-3019; DOI: https://doi.org/10.1105/tpc.109.069880

      Structural sterols are required for membrane integrity, cell growth, and plant development. This work shows that structural sterols are one of the early polarity markers during root hair formation and development in Arabidopsis. Local accumulation of structural sterols may regulate plasma membrane properties at the tip, vesicular trafficking, and progression of polarized tip growth of root hairs.

      Plant Cell Sep 2010, 22 (9) 3066-3075; DOI: https://doi.org/10.1105/tpc.110.077974

      Arabidopsis ATP binding cassette (ABC) transporters, ABCG11 and ACBG12, are required for export of different lipids from the epidermis to the cuticle. This study shows that ABCG11 and ABCG12 can form an obligate heterodimer and that ABCG11 can homodimerize. Live-cell imaging in epidermal cells demonstrates that localization of these ABCGs to the plasma membrane is dependent upon dimerization.

      Plant Cell Sep 2010, 22 (9) 3076-3092; DOI: https://doi.org/10.1105/tpc.110.077768

      The SNARE protein of Arabidopsis, SYP121, contributes to vesicle traffic and also controls the gating of K+ channels for K+ uptake by binding to the KC1 channel subunit. The identity of the KC1 binding site on the SNARE protein, described in this study, points to a novel role for the channel subunit in coordinating vesicle traffic.

      Plant Cell Sep 2010, 22 (9) 3142-3152; DOI: https://doi.org/10.1105/tpc.109.072090

      Replication of positive-strand RNA viruses, the largest group of plant viruses, is initiated by viral RNA-dependent RNA polymerase (RdRp). This work shows that Turnip yellow mosaic virus RdRp is a target of the ubiquitin-proteasome system in plant cells during viral infection and supports the idea that proteasomal degradation may constitute another level of regulation of viral replication.

      Plant Cell Sep 2010, 22 (9) 3164-3176; DOI: https://doi.org/10.1105/tpc.110.078022

      Copper is an essential micronutrient of plants and also an important element in a number of pesticides for crop protection. A pathogenic strain of bacterial blight, the most devastating bacterial disease of plants worldwide is sensitive to copper. Here, we show that this bacterium overcomes rice by regulating rice genes to remove copper from the site where it multiplies to cause disease.

      Plant Cell Sep 2010, 22 (9) 3053-3065; DOI: https://doi.org/10.1105/tpc.110.074351

      The plant cell cytokinesis is driven from the onset by highly organized vesicle fusion resulting in cell plate and new cell wall formation separating daughter cells. The evolutionarily conserved exocyst complex regulating exocytic vesicle binding to the plasma membrane is involved in both the final separation of cells as in animals and also in the initiation of cell plate in plant cells.

      Plant Cell Sep 2010, 22 (9) 3142-3152; DOI: https://doi.org/10.1105/tpc.109.072090

      Replication of positive-strand RNA viruses, the largest group of plant viruses, is initiated by viral RNA-dependent RNA polymerase (RdRp). This work shows that Turnip yellow mosaic virus RdRp is a target of the ubiquitin-proteasome system in plant cells during viral infection and supports the idea that proteasomal degradation may constitute another level of regulation of viral replication.

      Copper is an essential micronutrient of plants and also an important element in a number of pesticides for crop protection. A pathogenic strain of bacterial blight, the most devastating bacterial disease of plants worldwide is sensitive to copper. Here, we show that this bacterium overcomes rice by regulating rice genes to remove copper from the site where it multiplies to cause disease.

      Arabidopsis ATP binding cassette (ABC) transporters, ABCG11 and ACBG12, are required for export of different lipids from the epidermis to the cuticle. This study shows that ABCG11 and ABCG12 can form an obligate heterodimer and that ABCG11 can homodimerize. Live-cell imaging in epidermal cells demonstrates that localization of these ABCGs to the plasma membrane is dependent upon dimerization.

      Arabidopsis ATP binding cassette (ABC) transporters, ABCG11 and ACBG12, are required for export of different lipids from the epidermis to the cuticle. This study shows that ABCG11 and ABCG12 can form an obligate heterodimer and that ABCG11 can homodimerize. Live-cell imaging in epidermal cells demonstrates that localization of these ABCGs to the plasma membrane is dependent upon dimerization.

      Guillaume Blanc, Garry Duncan, Irina Agarkova, Mark Borodovsky, James Gurnon, Alan Kuo, Erika Lindquist, Susan Lucas, Jasmyn Pangilinan, Juergen Polle, Asaf Salamov, Astrid Terry, Takashi Yamada, David D. Dunigan, Igor V. Grigoriev, Jean-Michel Claverie, James L. Van Etten
      Plant Cell Sep 2010, 22 (9) 2943-2955; DOI: https://doi.org/10.1105/tpc.110.076406

      This report describes the genome sequence of Chlorella variabilis NC64A. Surprisingly, given that NC64A has been thought to be asexual and nonmotile, this work identifies homologs of genes involved in meiosis, gamete fusion, and flagella.

      Plant Cell Sep 2010, 22 (9) 3105-3117; DOI: https://doi.org/10.1105/tpc.109.071811

      Microalgae induce a carbon-concentrating mechanism to acclimate to CO2-limiting stress. This work provides evidence that a low CO2–inducible plasma membrane protein, LCI1, contributes to the carbon-concentrating mechanism as a component of the inorganic carbon transport machinery.

      Crystal Structures of a Populus tomentosa 4-Coumarate:CoA Ligase Shed Light on Its Enzymatic Mechanisms
      Yonglin Hu, Ying Gai, Lei Yin, Xiaoxue Wang, Chunyan Feng, Lei Feng, Defeng Li, Xiang-Ning Jiang, Da-Cheng Wang
      Plant Cell Sep 2010, 22 (9) 3093-3104; DOI: https://doi.org/10.1105/tpc.109.072652

      The crystal structure of Chinese white poplar 4-coumaric acid:coenzyme A ligase, the enzyme that catalyzes the synthesis of an important precursor of lignin, was determined in the apo, adenosine monophosphate-, and adenosine 5′-(3-(4-hydroxyphenyl)propyl)phosphate-complexed forms. Enzymatic mechanisms were proposed for the protein. Residues responsible for substrate specificity were identified.

      The Bacterial Pathogen Xanthomonas oryzae Overcomes Rice Defenses by Regulating Host Copper Redistribution
      Meng Yuan, Zhaohui Chu, Xianghua Li, Caiguo Xu, Shiping Wang
      Plant Cell Sep 2010, 22 (9) 3164-3176; DOI: https://doi.org/10.1105/tpc.110.078022

      Copper is an essential micronutrient of plants and also an important element in a number of pesticides for crop protection. A pathogenic strain of bacterial blight, the most devastating bacterial disease of plants worldwide is sensitive to copper. Here, we show that this bacterium overcomes rice by regulating rice genes to remove copper from the site where it multiplies to cause disease.

      The Arabidopsis Exocyst Complex Is Involved in Cytokinesis and Cell Plate Maturation
      Matyáš Fendrych, Lukáš Synek, Tamara Pečenková, Hana Toupalová, Rex Cole, Edita Drdová, Jana Nebesářová, Miroslava Šedinová, Michal Hála, John E. Fowler, Viktor Žárský
      Plant Cell Sep 2010, 22 (9) 3053-3065; DOI: https://doi.org/10.1105/tpc.110.074351

      The plant cell cytokinesis is driven from the onset by highly organized vesicle fusion resulting in cell plate and new cell wall formation separating daughter cells. The evolutionarily conserved exocyst complex regulating exocytic vesicle binding to the plasma membrane is involved in both the final separation of cells as in animals and also in the initiation of cell plate in plant cells.
