    NINJA connects the co-repressor TOPLESS to jasmonate signalling (2010)
    Nature Publishing Group (NPG)
    Details
    Publikationsdatum: 2010-04-03
    Beschreibung: Jasmonoyl-isoleucine (JA-Ile) is a plant hormone that regulates a broad array of plant defence and developmental processes. JA-Ile-responsive gene expression is regulated by the transcriptional activator MYC2 that interacts physically with the jasmonate ZIM-domain (JAZ) repressor proteins. On perception of JA-Ile, JAZ proteins are degraded and JA-Ile-dependent gene expression is activated. The molecular mechanisms by which JAZ proteins repress gene expression remain unknown. Here we show that the Arabidopsis JAZ proteins recruit the Groucho/Tup1-type co-repressor TOPLESS (TPL) and TPL-related proteins (TPRs) through a previously uncharacterized adaptor protein, designated Novel Interactor of JAZ (NINJA). NINJA acts as a transcriptional repressor whose activity is mediated by a functional TPL-binding EAR repression motif. Accordingly, both NINJA and TPL proteins function as negative regulators of jasmonate responses. Our results point to TPL proteins as general co-repressors that affect multiple signalling pathways through the interaction with specific adaptor proteins. This new insight reveals how stress-related and growth-related signalling cascades use common molecular mechanisms to regulate gene expression in plants.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2849182/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2849182/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pauwels, Laurens -- Barbero, Gemma Fernandez -- Geerinck, Jan -- Tilleman, Sofie -- Grunewald, Wim -- Perez, Amparo Cuellar -- Chico, Jose Manuel -- Bossche, Robin Vanden -- Sewell, Jared -- Gil, Eduardo -- Garcia-Casado, Gloria -- Witters, Erwin -- Inze, Dirk -- Long, Jeff A -- De Jaeger, Geert -- Solano, Roberto -- Goossens, Alain -- R01 GM072764/GM/NIGMS NIH HHS/ -- R01 GM072764-06/GM/NIGMS NIH HHS/ -- England -- Nature. 2010 Apr 1;464(7289):788-91. doi: 10.1038/nature08854.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Systems Biology, Flanders Institute for Biotechnology (VIB), Technologiepark 927, B-9052 Gent, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20360743" target="_blank"〉PubMed〈/a〉

    Reactome array: forging a link between metabolome and genome (2009)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2009-10-10
    Beschreibung: We describe a sensitive metabolite array for genome sequence-independent functional analysis of metabolic phenotypes and networks, the reactomes, of cell populations and communities. The array includes 1676 dye-linked substrate compounds collectively representing central metabolic pathways of all forms of life. Application of cell extracts to the array leads to specific binding of enzymes to cognate substrates, transformation to products, and concomitant activation of the dye signals. Proof of principle was shown by reconstruction of the metabolic maps of model bacteria. Utility of the array for unsequenced organisms was demonstrated by reconstruction of the global metabolisms of three microbial communities derived from acidic volcanic pool, deep-sea brine lake, and hydrocarbon-polluted seawater. Enzymes of interest are captured on nanoparticles coated with cognate metabolites, sequenced, and their functions unequivocally established.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Beloqui, Ana -- Guazzaroni, Maria-Eugenia -- Pazos, Florencio -- Vieites, Jose M -- Godoy, Marta -- Golyshina, Olga V -- Chernikova, Tatyana N -- Waliczek, Agnes -- Silva-Rocha, Rafael -- Al-Ramahi, Yamal -- La Cono, Violetta -- Mendez, Carmen -- Salas, Jose A -- Solano, Roberto -- Yakimov, Michail M -- Timmis, Kenneth N -- Golyshin, Peter N -- Ferrer, Manuel -- New York, N.Y. -- Science. 2009 Oct 9;326(5950):252-7. doi: 10.1126/science.1174094.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉CSIC, Institute of Catalysis, 28049 Madrid, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19815770" target="_blank"〉PubMed〈/a〉

    Interception and retention of macroscopic bryophyte fragments by branch substrates in a tropical cloud forest: an experimental and demographic approach (2000)

    Notizen: Abstract  Although the significance of canopy plant communities to ecosystem function is well documented, the process by which such communities become established in trees remains poorly known. Colonization of tree surfaces by canopy-dwelling plants often begins with the establishment of bryophytes, so the conditions that affect the dispersal of bryophytes in the forest canopy merit study. We assessed success rates of one mechanism of bryophyte propagation, the aerial dispersal of macroscopic fragments, using an experimental approach. We quantified interception and retention of marked fragments released from a 36 cm×36 cm grid 50 cm above branches of saplings and mature trees of the species Ocotea tonduzii in a montane cloud forest in Costa Rica. Only 1% of bryophyte fragments dropped over sapling crowns in this manner were retained for the 6-month duration of the study, while branches in the forest canopy with intact epiphyte loads and branches that had been stripped of their epiphytes retained 24% and 5%, respectively. Our results suggest that larger-diameter branches and the presence of other epiphytes can both improve the retention of bryophyte fragments on canopy branches. Further work will be needed to address the relative roles of other dispersal mechanisms (spores, gemmae, microscopic bryophyte fragments) and the dynamics of growth and establishment of macroscopic bryophyte fragments following their interception.

    Notizen: Summary Four repetitive sequences from Avena murphyi have been isolated and their genome organization studied in different species of the genus Avena. A tandem sequence array was found for the Avena species that contain the C genome. Three other dispersed sequences present in the A and C genomes were arranged in a genomespecific manner. The fact that no major differences in the hybridization patterns were found between species with the same basic genome is consistent with the current taxonomy of Avena species.

    Beschreibung / Inhaltsverzeichnis: Verhalten von ferritischem Stahl Irn ML-1 NatriumkorrosionskreislaufDer ferritische Stahl AISI 430 wurde 6000 h bei 500 und 570 °C im ML-1 Natriumkreislauf ausgelagert. Die Proben wurden zur Auswertung der Korrosions- und Ablagerungseffekte nachuntersucht. Zusätzlich zu den Gewichtsänderungsmessungen und metallographischen Techniken wurden Oberflächenanalysen mit der Glimmentladungsspektrometrie und der AUGER-Elektronenspektrometrie sowie das Rasterelektronenmikroskop mit Röntgen-Analyse herangezogen.Korrosion und Ablagerung beeinflußten etwa 0,01 mm dünne Schichten, die Gewichtsverluste waren denen der austenitischen Stähle vergleichbar. Der Stahl wurde durch Natrium nicht entkohlt. Auf den Oberflächen hatten sich Sauerstoff enthaltende Verbindungen gebildet. In der Zone der Abströmung wurden auch metallische Ablagerungen, die an Nickel reich waren, beobachtet.
    Notizen: The ferritic steel AISI 430 has been exposed up to 6000 hours at 500 and 570 °C in the ML-1 sodium loop. The specimens were examined to evaluate the corrosion and mass transfer phenomena. Additional to weight change measurements and metallographic techniques surface layer analyses by Glow Discharge Optical Spectrometry and AUGER Electron Spectrometry and also scanning electron microscopy with Xray analysis were applied.Corrosion and deposition influenced about 0.01 mm thin layers, weight losses were comparable to those of austenitic steels. The steel was not decarburized by the sodium. On the surfaces oxygen containing compounds have formed. In the down-stream area also metallic deposits rich in nickel were observed.
