      Abscisic Acid–Responsive Guard Cell Metabolomes of Arabidopsis Wild-Type and gpa1 G-Protein Mutants
      Xiaofen Jin, Rui-Sheng Wang, Mengmeng Zhu, Byeong Wook Jeon, Reka Albert, Sixue Chen, Sarah M. Assmann
      Plant Cell Dec 2013, 25 (12) 4789-4811; DOI: https://doi.org/10.1105/tpc.113.119800

      The authors performed metabolomics analysis on a time series of guard cell samples treated with abscisic acid (ABA) to follow the dynamics of 85 metabolites potentially involved in ABA signaling. ABA rapidly altered the profiles of numerous metabolites, including other hormones and calcium-mobilizing agents. ABA responses were greater in the wild type than in a G-protein mutant with ABA-hyposensitive stomata.

      Genome-Wide Analysis of Branched-Chain Amino Acid Levels in Arabidopsis Seeds
      Ruthie Angelovici, Alexander E. Lipka, Nicholas Deason, Sabrina Gonzalez-Jorge, Haining Lin, Jason Cepela, Robin Buell, Michael A. Gore, Dean DellaPenna
      Plant Cell Dec 2013, 25 (12) 4827-4843; DOI: https://doi.org/10.1105/tpc.113.119370

      Genome-wide association studies of free branched-chain amino acids (BCAAs) in Arabidopsis seeds identified BRANCHED-CHAIN AMINO ACID TRANSFERASE2 (BCAT2), one of seven BCATs encoded in the genome, as an important regulator of BCAA natural variation. The mitochondrial localization of BCAT2 is consistent with a catabolic function and highlights the importance of catabolism in determining seed BCAA levels.

      Plant Cell Dec 2013, 25 (12) 4812-4826; DOI: https://doi.org/10.1105/tpc.113.119677

      Analysis of natural variation in Arabidopsis identified CAROTENOID CLEAVAGE DIOXYGENASE4 (CCD4) as a major negative regulator of β-carotene content in seeds and senescing leaves. Given that global vitamin A deficiency is due in part to low β-carotene levels in seeds of major food crops, this study suggests that CCDs may be critical targets for enhancing the provitamin A carotenoid levels of food crops.

      NAC Transcription Factor SPEEDY HYPONASTIC GROWTH Regulates Flooding-Induced Leaf Movement in Arabidopsis
      Mamoona Rauf, Muhammad Arif, Joachim Fisahn, Gang-Ping Xue, Salma Balazadeh, Bernd Mueller-Roeber
      Plant Cell Dec 2013, 25 (12) 4941-4955; DOI: https://doi.org/10.1105/tpc.113.117861

      In rosette plants, waterlogging triggers an upward (hyponastic) leaf movement that positions the photosynthetically active organs above the rising water level. This work reports the identification of a transcriptional regulator that affects this response by regulating the expression of its direct target gene, ACO5, encoding ACC oxidase, a key enzyme of ethylene biosynthesis.

      The Tannat grape berry is used to produce high-quality wines with an intense purple color and remarkable antioxidant properties. Through reference-guided assembly of the genome combined with de novo assembly of the transcriptome, we found that the variety-specific genes that might contribute substantially to the unique characteristics of the Tannat berry are not present in the reference genome.

      Plant Cell Dec 2013, 25 (12) 4879-4893; DOI: https://doi.org/10.1105/tpc.113.115576

      Sterol biosynthetic intermediates (SBIs) derived from the sterol C4-demethylation complex tethered by ERG28 represent signaling molecules in mammals and fungi. In Arabidopsis, loss of ERG28 function leads to the accumulation of the previously undetected SBI, 4-carboxy-4-methyl-24-methylenecycloartanol, which inhibits polar auxin transport. Our work provides a link between sterol metabolism and auxin transport.

      Biosynthesis of the amino acid serine occurs mainly via photorespiration in plants. This work shows, however, that locally restricted serine biosynthesis via the alternative phosphoserine pathway is required for proper embryo development and leaf initiation, highlighting the importance of cellular resolution when analyzing metabolic pathways.

      Plant growth follows positional cues provided by the phytohormone auxin. A key determinant of auxin distribution is the asymmetric plasma membrane localization of PIN-auxin transporters, which involves complex endocytotic cycling. Endocytosis and PIN distribution require the regulatory phospholipid, PtdIns(4,5)P2, which is formed by PI4P 5-kinases that themselves display polarized distribution.

      Plant Cell Dec 2013, 25 (12) 4984-4993; DOI: https://doi.org/10.1105/tpc.113.119172

      This work provides evidence into how inhibition of the methylerythritol phosphate pathway causes plant death. Chlorophyll is composed of a chlorin ring, generated by the tetrapyrrole pathway, and an isoprenoid tail, made from the methylerythritol phosphate pathway. The data herein demonstrate that stoichiometric balance between these pathways is essential for viability.

      Analysis of natural variation in Arabidopsis identified CAROTENOID CLEAVAGE DIOXYGENASE4 (CCD4) as a major negative regulator of β-carotene content in seeds and senescing leaves. Given that global vitamin A deficiency is due in part to low β-carotene levels in seeds of major food crops, this study suggests that CCDs may be critical targets for enhancing the provitamin A carotenoid levels of food crops.

      This article elucidates molecular details of meiotic DNA repair by analyzing the interhomolog-promoting factor HOP2. The study found that the recombinase DMC1 requires high levels of HOP2 for repair via the homologous chromosome but only minimal amounts to allow the recombinase RAD51 to perform intersister DNA repair, indicating that DMC1 exerts a negative regulatory effect on RAD51, which is alleviated by HOP2.

      The authors performed metabolomics analysis on a time series of guard cell samples treated with abscisic acid (ABA) to follow the dynamics of 85 metabolites potentially involved in ABA signaling. ABA rapidly altered the profiles of numerous metabolites, including other hormones and calcium-mobilizing agents. ABA responses were greater in the wild type than in a G-protein mutant with ABA-hyposensitive stomata.

      Plant growth follows positional cues provided by the phytohormone auxin. A key determinant of auxin distribution is the asymmetric plasma membrane localization of PIN-auxin transporters, which involves complex endocytotic cycling. Endocytosis and PIN distribution require the regulatory phospholipid, PtdIns(4,5)P2, which is formed by PI4P 5-kinases that themselves display polarized distribution.

      Biosynthesis of the amino acid serine occurs mainly via photorespiration in plants. This work shows, however, that locally restricted serine biosynthesis via the alternative phosphoserine pathway is required for proper embryo development and leaf initiation, highlighting the importance of cellular resolution when analyzing metabolic pathways.

      Analysis of natural variation in Arabidopsis identified CAROTENOID CLEAVAGE DIOXYGENASE4 (CCD4) as a major negative regulator of β-carotene content in seeds and senescing leaves. Given that global vitamin A deficiency is due in part to low β-carotene levels in seeds of major food crops, this study suggests that CCDs may be critical targets for enhancing the provitamin A carotenoid levels of food crops.

      Phenylalanine ammonia-lyase (PAL) catalyzes the first rate-limiting step in the phenylpropanoid pathway. Both in vitro and in vivo biochemical and genetic evidence demonstrated that a group of Kelch repeat F-box proteins physically interact with PAL isozymes, mediating their degradation via the ubiquitination-26S proteasome system, thus affecting phenylpropanoid biosynthesis.

      This article elucidates molecular details of meiotic DNA repair by analyzing the interhomolog-promoting factor HOP2. The study found that the recombinase DMC1 requires high levels of HOP2 for repair via the homologous chromosome but only minimal amounts to allow the recombinase RAD51 to perform intersister DNA repair, indicating that DMC1 exerts a negative regulatory effect on RAD51, which is alleviated by HOP2.

      Plant growth follows positional cues provided by the phytohormone auxin. A key determinant of auxin distribution is the asymmetric plasma membrane localization of PIN-auxin transporters, which involves complex endocytotic cycling. Endocytosis and PIN distribution require the regulatory phospholipid, PtdIns(4,5)P2, which is formed by PI4P 5-kinases that themselves display polarized distribution.

      Plant growth follows positional cues provided by the phytohormone auxin. A key determinant of auxin distribution is the asymmetric plasma membrane localization of PIN-auxin transporters, which involves complex endocytotic cycling. Endocytosis and PIN distribution require the regulatory phospholipid, PtdIns(4,5)P2, which is formed by PI4P 5-kinases that themselves display polarized distribution.

      Plant growth follows positional cues provided by the phytohormone auxin. A key determinant of auxin distribution is the asymmetric plasma membrane localization of PIN-auxin transporters, which involves complex endocytotic cycling. Endocytosis and PIN distribution require the regulatory phospholipid, PtdIns(4,5)P2, which is formed by PI4P 5-kinases that themselves display polarized distribution.

      Biosynthesis of the amino acid serine occurs mainly via photorespiration in plants. This work shows, however, that locally restricted serine biosynthesis via the alternative phosphoserine pathway is required for proper embryo development and leaf initiation, highlighting the importance of cellular resolution when analyzing metabolic pathways.

      Sterol biosynthetic intermediates (SBIs) derived from the sterol C4-demethylation complex tethered by ERG28 represent signaling molecules in mammals and fungi. In Arabidopsis, loss of ERG28 function leads to the accumulation of the previously undetected SBI, 4-carboxy-4-methyl-24-methylenecycloartanol, which inhibits polar auxin transport. Our work provides a link between sterol metabolism and auxin transport.

      Plant growth follows positional cues provided by the phytohormone auxin. A key determinant of auxin distribution is the asymmetric plasma membrane localization of PIN-auxin transporters, which involves complex endocytotic cycling. Endocytosis and PIN distribution require the regulatory phospholipid, PtdIns(4,5)P2, which is formed by PI4P 5-kinases that themselves display polarized distribution.

      Sterol biosynthetic intermediates (SBIs) derived from the sterol C4-demethylation complex tethered by ERG28 represent signaling molecules in mammals and fungi. In Arabidopsis, loss of ERG28 function leads to the accumulation of the previously undetected SBI, 4-carboxy-4-methyl-24-methylenecycloartanol, which inhibits polar auxin transport. Our work provides a link between sterol metabolism and auxin transport.

      This article elucidates molecular details of meiotic DNA repair by analyzing the interhomolog-promoting factor HOP2. The study found that the recombinase DMC1 requires high levels of HOP2 for repair via the homologous chromosome but only minimal amounts to allow the recombinase RAD51 to perform intersister DNA repair, indicating that DMC1 exerts a negative regulatory effect on RAD51, which is alleviated by HOP2.

      Phosphatidic acid has emerged as a class of cellular mediators involved in various cellular and physiological processes. However, little is known about its mechanism of action. This study shows that phosphatidic acid binds to the MYB transcription factor WER and suggests that the interaction is necessary for the nuclear localization of WER and for WER-mediated regulation of root hair formation.

      The authors performed metabolomics analysis on a time series of guard cell samples treated with abscisic acid (ABA) to follow the dynamics of 85 metabolites potentially involved in ABA signaling. ABA rapidly altered the profiles of numerous metabolites, including other hormones and calcium-mobilizing agents. ABA responses were greater in the wild type than in a G-protein mutant with ABA-hyposensitive stomata.

      This work shows that a mutation of the ARGONAUTE7 ortholog (LOBED LEAFLET1) in Medicago truncatula causes lobed leaf margins and more widely spaced lateral organs. Characterization of the mutant revealed a balanced developmental mechanism involving several regulators that determine the final shape of leaf margin and the separation of lateral organs.

      Plant growth follows positional cues provided by the phytohormone auxin. A key determinant of auxin distribution is the asymmetric plasma membrane localization of PIN-auxin transporters, which involves complex endocytotic cycling. Endocytosis and PIN distribution require the regulatory phospholipid, PtdIns(4,5)P2, which is formed by PI4P 5-kinases that themselves display polarized distribution.

      In rosette plants, waterlogging triggers an upward (hyponastic) leaf movement that positions the photosynthetically active organs above the rising water level. This work reports the identification of a transcriptional regulator that affects this response by regulating the expression of its direct target gene, ACO5, encoding ACC oxidase, a key enzyme of ethylene biosynthesis.

      The Tannat grape berry is used to produce high-quality wines with an intense purple color and remarkable antioxidant properties. Through reference-guided assembly of the genome combined with de novo assembly of the transcriptome, we found that the variety-specific genes that might contribute substantially to the unique characteristics of the Tannat berry are not present in the reference genome.

      Phenylalanine ammonia-lyase (PAL) catalyzes the first rate-limiting step in the phenylpropanoid pathway. Both in vitro and in vivo biochemical and genetic evidence demonstrated that a group of Kelch repeat F-box proteins physically interact with PAL isozymes, mediating their degradation via the ubiquitination-26S proteasome system, thus affecting phenylpropanoid biosynthesis.

      Analysis of natural variation in Arabidopsis identified CAROTENOID CLEAVAGE DIOXYGENASE4 (CCD4) as a major negative regulator of β-carotene content in seeds and senescing leaves. Given that global vitamin A deficiency is due in part to low β-carotene levels in seeds of major food crops, this study suggests that CCDs may be critical targets for enhancing the provitamin A carotenoid levels of food crops.
