- You have accessRestricted AccessDistinct Roles of the ATR Kinase and the Mre11-Rad50-Nbs1 Complex in the Maintenance of Chromosomal Stability in ArabidopsisSimon Amiard, Cyril Charbonnel, Elisabeth Allain, Annie Depeiges, Charles I. White, Maria Eugenia GallegoPlant 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.

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.

LichtscheidlPlant 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.

Unexpectedly, this heat-induced transcriptional activation does not require DNA demethylation or change of histone modification, but rather involves a dramatic reduction of nucleosome association with the DNA.

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.

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.

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.

Fowler, Viktor ŽárskýPlant 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.

Fowler, Viktor ŽárskýPlant 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.

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.

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.

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.

Fowler, Viktor ŽárskýPlant 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.

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.

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.

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.

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.

Nitric oxide has been proposed to act as a signal for numerous physiological and developmental processes in plants. This work describes the involvement of the mitogen-activated protein kinase (MPK) cascade in nitric oxide synthesis via nitrate reductase. It demonstrates H2O2-mediated MPK6 activation of nitric oxide production and signal transduction during root development in Arabidopsis.

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.

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.
