  1. Kuhn C, Grof C. Sucrose transporters of higher plants. Curr Opin Plant Biol. 2010;13:288-98 pubmed publisher

  3. Werner A, Sparkes I, Romeis T, Witte C. Identification, biochemical characterization, and subcellular localization of allantoate amidohydrolases from Arabidopsis and soybean. Plant Physiol. 2008;146:418-30 pubmed
    ..These findings demonstrate that after the generation of allantoin in the peroxisome, plant purine degradation continues in the endoplasmic reticulum. ..

    ..Further investigations are in progress to elucidate functions of the AtDMP proteins. ..
  5. Tillich M, Beick S, Schmitz Linneweber C. Chloroplast RNA-binding proteins: repair and regulation of chloroplast transcripts. RNA Biol. 2010;7:172-8 pubmed
    ..By contrast, the chloroplast ribonucleoproteins (cpRNPs), which are strongly modulated by external and internal stimuli, are suggested to be major players in transducing signals to the chloroplast transcript pool. ..
  6. Witte C, Keinath N, Dubiella U, Demoulière R, Seal A, Romeis T. Tobacco calcium-dependent protein kinases are differentially phosphorylated in vivo as part of a kinase cascade that regulates stress response. J Biol Chem. 2010;285:9740-8 pubmed publisher
    ..Our data indicate that CDPKs are integrated in stress-dependent protein kinase signaling cascades, and regulation of CDPK function in response to in vivo stimulation is dependent on its membrane localization. ..
  7. Tillich M, Hardel S, Kupsch C, Armbruster U, Delannoy E, Gualberto J, et al. Chloroplast ribonucleoprotein CP31A is required for editing and stability of specific chloroplast mRNAs. Proc Natl Acad Sci U S A. 2009;106:6002-7 pubmed publisher
    ..Taken together, the specificity and combinatorial aspects of cpRNP functions uncovered suggest that these chloroplast proteins are functional equivalents of nucleocytosolic hnRNPs. ..
  8. Schmitz Linneweber C, Small I. Pentatricopeptide repeat proteins: a socket set for organelle gene expression. Trends Plant Sci. 2008;13:663-70 pubmed publisher
    ..We use these new data to propose hypotheses for their physiological roles that could explain why PPR proteins are so numerous in terrestrial plants. ..
  9. Beick S, Schmitz Linneweber C, Williams Carrier R, Jensen B, Barkan A. The pentatricopeptide repeat protein PPR5 stabilizes a specific tRNA precursor in maize chloroplasts. Mol Cell Biol. 2008;28:5337-47 pubmed publisher
    ..These findings add to the evidence that chloroplast-localized PPR proteins that are embryo essential in Arabidopsis typically function in the biogenesis of the plastid translation machinery. ..
