      Patatin-Related Phospholipase pPLAIIIβ-Induced Changes in Lipid Metabolism Alter Cellulose Content and Cell Elongation in Arabidopsis
      Maoyin Li, Sung Chul Bahn, Liang Guo, William Musgrave, Howard Berg, Ruth Welti, Xuemin Wang
      Plant Cell Mar 2011, 23 (3) 1107-1123; DOI: https://doi.org/10.1105/tpc.110.081240

      Patatin-related phospholipase pPLAIIIβ lacks the canonical esterase catalytic center but possesses acyl-hydrolyzing and acyl-CoA thioesterase activities. Knockout and overexpression of pPLAIIIβ have opposite effects on the levels of membrane lipids, cellulose content, mechanical strength, and cell length. Thus, membrane lipid metabolism may be linked to cellulose production in Arabidopsis.

      Disruption of LACCASE4 and 17 Results in Tissue-Specific Alterations to Lignification of Arabidopsis thaliana Stems
      Serge Berthet, Nathalie Demont-Caulet, Brigitte Pollet, Przemyslaw Bidzinski, Laurent Cézard, Phillipe Le Bris, Nero Borrega, Jonathan Hervé, Eddy Blondet, Sandrine Balzergue, Catherine Lapierre, Lise Jouanin
      Plant Cell Mar 2011, 23 (3) 1124-1137; DOI: https://doi.org/10.1105/tpc.110.082792

      This study provides evidence that two laccases, LAC4 and LAC17, participate in the polymerization of lignins in Arabidopsis stems. These findings suggest that the genetic engineering of lignin-specific laccases is a potentially innovative and promising tool for the fine-tuning of lignin content and structure.

      APO1 Promotes the Splicing of Chloroplast Group II Introns and Harbors a Plant-Specific Zinc-Dependent RNA Binding Domain
      Kenneth P. Watkins, Margarita Rojas, Giulia Friso, Klaas J. van Wijk, Jörg Meurer, Alice Barkan
      Plant Cell Mar 2011, 23 (3) 1082-1092; DOI: https://doi.org/10.1105/tpc.111.084335

      This study demonstrates that APO1, originally proposed to be involved in the maturation of proteins with [4Fe-4S] ligands, is instead required for the splicing of several chloroplast introns. It shows further that DUF794, the plant-specific domain of unknown function that makes up the bulk of APO1, is an RNA binding domain harboring zinc binding motifs.

      Multiple Facets of Arabidopsis Seedling Development Require Indole-3-Butyric Acid–Derived Auxin
      Lucia C. Strader, Dorthea L. Wheeler, Sarah E. Christensen, John C. Berens, Jerry D. Cohen, Rebekah A. Rampey, Bonnie Bartel
      Plant Cell Mar 2011, 23 (3) 984-999; DOI: https://doi.org/10.1105/tpc.111.083071

      Plants synthesize the growth hormone indole-3-acetic acid using a variety of incompletely understood pathways. This work demonstrates that the conversion of indole-3-butyric acid to indole-3-acetic acid contributes to wide-ranging auxin-regulated processes in Arabidopsis seedlings and that shutting off this auxin supply renders seedlings less able to respond to exogenous auxin.

      Plant Cell Mar 2011, 23 (3) 1061-1081; DOI: https://doi.org/10.1105/tpc.110.079095

      Sphingolipids are a diverse group of essential membrane lipids thought to play important roles in both membrane function and cellular signaling. By identifying an Arabidopsis thaliana mutant lacking 3-ketodihydrosphinganine reductase, a critical enzyme in sphingolipid biosynthesis, this work uncovers a connection between sphingolipid metabolism in roots and whole-plant mineral ion homeostasis.

      Geminiviruses Subvert Ubiquitination by Altering CSN-Mediated Derubylation of SCF E3 Ligase Complexes and Inhibit Jasmonate Signaling in Arabidopsis thaliana
      Rosa Lozano-Durán, Tabata Rosas-Díaz, Giuliana Gusmaroli, Ana P. Luna, Ludivine Taconnat, Xing Wang Deng, Eduardo R. Bejarano
      Plant Cell Mar 2011, 23 (3) 1014-1032; DOI: https://doi.org/10.1105/tpc.110.080267

      This study shows that geminivirus C2/L2 protein interferes with the derubylation of CUL1. Responses regulated by the CUL1-based SCF ubiquitin ligases, and particularly the response to jasmonates, are altered in transgenic Arabidopsis thaliana expressing C2/L2. The capability to selectively interfere with SCF complexes may define a novel and powerful strategy in viral infections.

      Plant Cell Mar 2011, 23 (3) 911-922; DOI: https://doi.org/10.1105/tpc.110.082529

      Protein–protein interactions are important mechanisms for genes and gene networks to function. This study demonstrates that, although the PAIR database has limited coverage, representing ~24% of the entire interactome with ~40% precision, it is rich enough to capture many significant functional linkages within and between higher-order biological systems, such as pathways and biological processes.

      The Emerging Importance of Type I MADS Box Transcription Factors for Plant Reproduction

      Plant Cell Mar 2011, 23 (3) 865-872; DOI: https://doi.org/10.1105/tpc.110.081737

      Based on their evolutionary origin, MADS box transcription factor genes have been divided into two classes, namely, type I and II. The plant-specific type II MIKC MADS box genes have been most intensively studied and shown to be key regulators of developmental processes, such as meristem identity, flowering time, and fruit and seed development. By contrast, very little is known about type I MADS domain transcription factors, and they have not attracted interest for a long time. A number of recent studies have now indicated a key regulatory role for type I MADS box factors in plant reproduction, in particular in specifying female gametophyte, embryo, and endosperm development. These analyses have also suggested that type I MADS box factors are decisive for setting reproductive boundaries between species.

Knockout and overexpression of pPLAIIIβ have opposite effects on the levels of membrane lipids, cellulose content, mechanical strength, and cell length. Thus, membrane lipid metabolism may be linked to cellulose production in Arabidopsis.

      The Emerging Importance of Type I MADS Box Transcription Factors for Plant Reproduction

      Based on their evolutionary origin, MADS box transcription factor genes have been divided into two classes, namely, type I and II. The plant-specific type II MIKC MADS box genes have been most intensively studied and shown to be key regulators of developmental processes, such as meristem identity, flowering time, and fruit and seed development. By contrast, very little is known about type I MADS domain transcription factors, and they have not attracted interest for a long time. A number of recent studies have now indicated a key regulatory role for type I MADS box factors in plant reproduction, in particular in specifying female gametophyte, embryo, and endosperm development. These analyses have also suggested that type I MADS box factors are decisive for setting reproductive boundaries between species.

      Plant Cell Mar 2011, 23 (3) 1014-1032; DOI: https://doi.org/10.1105/tpc.110.080267

      This study shows that geminivirus C2/L2 protein interferes with the derubylation of CUL1. Responses regulated by the CUL1-based SCF ubiquitin ligases, and particularly the response to jasmonates, are altered in transgenic Arabidopsis thaliana expressing C2/L2. The capability to selectively interfere with SCF complexes may define a novel and powerful strategy in viral infections.

      Sphingolipids are a diverse group of essential membrane lipids thought to play important roles in both membrane function and cellular signaling. By identifying an Arabidopsis thaliana mutant lacking 3-ketodihydrosphinganine reductase, a critical enzyme in sphingolipid biosynthesis, this work uncovers a connection between sphingolipid metabolism in roots and whole-plant mineral ion homeostasis.

      The Emerging Importance of Type I MADS Box Transcription Factors for Plant Reproduction

      Plant Cell Mar 2011, 23 (3) 865-872; DOI: https://doi.org/10.1105/tpc.110.081737

      Based on their evolutionary origin, MADS box transcription factor genes have been divided into two classes, namely, type I and II. The plant-specific type II MIKC MADS box genes have been most intensively studied and shown to be key regulators of developmental processes, such as meristem identity, flowering time, and fruit and seed development. By contrast, very little is known about type I MADS domain transcription factors, and they have not attracted interest for a long time. A number of recent studies have now indicated a key regulatory role for type I MADS box factors in plant reproduction, in particular in specifying female gametophyte, embryo, and endosperm development. These analyses have also suggested that type I MADS box factors are decisive for setting reproductive boundaries between species.

      Patatin-related phospholipase pPLAIIIβ lacks the canonical esterase catalytic center but possesses acyl-hydrolyzing and acyl-CoA thioesterase activities. Knockout and overexpression of pPLAIIIβ have opposite effects on the levels of membrane lipids, cellulose content, mechanical strength, and cell length. Thus, membrane lipid metabolism may be linked to cellulose production in Arabidopsis.

      Based on their evolutionary origin, MADS box transcription factor genes have been divided into two classes, namely, type I and II. The plant-specific type II MIKC MADS box genes have been most intensively studied and shown to be key regulators of developmental processes, such as meristem identity, flowering time, and fruit and seed development. By contrast, very little is known about type I MADS domain transcription factors, and they have not attracted interest for a long time. A number of recent studies have now indicated a key regulatory role for type I MADS box factors in plant reproduction, in particular in specifying female gametophyte, embryo, and endosperm development. These analyses have also suggested that type I MADS box factors are decisive for setting reproductive boundaries between species.

      Patatin-Related Phospholipase pPLAIIIβ-Induced Changes in Lipid Metabolism Alter Cellulose Content and Cell Elongation in Arabidopsis
      Maoyin Li, Sung Chul Bahn, Liang Guo, William Musgrave, Howard Berg, Ruth Welti, Xuemin Wang
      Plant Cell Mar 2011, 23 (3) 1107-1123; DOI: https://doi.org/10.1105/tpc.110.081240

      Patatin-related phospholipase pPLAIIIβ lacks the canonical esterase catalytic center but possesses acyl-hydrolyzing and acyl-CoA thioesterase activities. Knockout and overexpression of pPLAIIIβ have opposite effects on the levels of membrane lipids, cellulose content, mechanical strength, and cell length. Thus, membrane lipid metabolism may be linked to cellulose production in Arabidopsis.

      APO1 Promotes the Splicing of Chloroplast Group II Introns and Harbors a Plant-Specific Zinc-Dependent RNA Binding Domain
      Kenneth P. Watkins, Margarita Rojas, Giulia Friso, Klaas J. van Wijk, Jörg Meurer, Alice Barkan
      Plant Cell Mar 2011, 23 (3) 1082-1092; DOI: https://doi.org/10.1105/tpc.111.084335

      This study demonstrates that APO1, originally proposed to be involved in the maturation of proteins with [4Fe-4S] ligands, is instead required for the splicing of several chloroplast introns. It shows further that DUF794, the plant-specific domain of unknown function that makes up the bulk of APO1, is an RNA binding domain harboring zinc binding motifs.

      Multiple Facets of Arabidopsis Seedling Development Require Indole-3-Butyric Acid–Derived Auxin
      Lucia C. Strader, Dorthea L. Wheeler, Sarah E. Christensen, John C. Berens, Jerry D. Cohen, Rebekah A. Rampey, Bonnie Bartel
      Plant Cell Mar 2011, 23 (3) 984-999; DOI: https://doi.org/10.1105/tpc.111.083071

      Plants synthesize the growth hormone indole-3-acetic acid using a variety of incompletely understood pathways. This work demonstrates that the conversion of indole-3-butyric acid to indole-3-acetic acid contributes to wide-ranging auxin-regulated processes in Arabidopsis seedlings and that shutting off this auxin supply renders seedlings less able to respond to exogenous auxin.

      Plant Cell Mar 2011, 23 (3) 895-910; DOI: https://doi.org/10.1105/tpc.111.083667

      Genes that are similarly expressed, or coexpressed, are often involved in related biological processes. Such coexpressed relationships also appear to be conserved across species. The PlaNet platform enables comparative analysis of genome-wide coexpression networks across seven plant species, thus enabling prediction of gene function and elucidation of the identity of functional homologs.

      Plant Cell Mar 2011, 23 (3) 911-922; DOI: https://doi.org/10.1105/tpc.110.082529

      Protein–protein interactions are important mechanisms for genes and gene networks to function. This study demonstrates that, although the PAIR database has limited coverage, representing ~24% of the entire interactome with ~40% precision, it is rich enough to capture many significant functional linkages within and between higher-order biological systems, such as pathways and biological processes.
