Volatiles of Stenotrophomonas, Serratia, and Bacillus species inhibited mycelial growth of many fungi and Arabidopsis thaliana (40 to 98%), and volatiles of Pseudomonas species and Burkholderia cepacia retarded the growth to lesser extents. Aspergillus niger and Fusarium species were resistant, and
The genomes of Arabidopsis and other plants contain cysteine-rich small protein of unknown function, harbouring a transmembrane module (CYSTM proteins). In this work we show that the transcript of one gene (At1g05340) encoding a CYSTM protein is induced mainly by heat and to a lesser extent by UV,
Previous studies have demonstrated that the genetic modification of basal salicylic acid (SA) level changed Arabidopsis plant response to cadmium (Cd) stress, but the mechanisms remain evaluated. In this study, Arabidopsis wild type (WT) and its SA-reducing transgenic line nahG (naphthalene
We investigated the role of metabolite transporters in cold acclimation by comparing the responses of wild-type (WT) Arabidopsis thaliana (Heynh.) with that of transgenic plants over-expressing sucrose-phosphate synthase (SPSox) or with that of antisense repression of cytosolic
Six Arabidopsis (Arabidopsis thaliana) clade A protein phosphatase 2Cs (PP2Cs) have established abscisic acid (ABA) signaling roles; however, phenotypic roles of the remaining three "HAI" PP2Cs, Highly ABA-Induced1 (HAI1), AKT1-Interacting PP2C1/HAI2, and HAI3, have remained unclear. HAI PP2C
Transgenic tobacco plants that overexpress the ARGOS-LIKE (ARL) gene of Arabidopsis thaliana have been developed. The transgenic plants possessed increased dimensions of leaves and stem, whereas the magnitude of flowers was modified to a lesser degree. The increase in the organ dimensions was a
Although the surface waxes from Arabidopsis thaliana leaves and stems have been thoroughly characterized, the monomer composition of the polyesters of the cuticular membrane has not been analyzed. Delipidated Arabidopsis leaves or stems, when depolymerized under conditions to cleave polyesters,
CONCLUSIONS
Leaf morphological differences have an impact on light distribution within the leaf, photosynthesis, and photoprotection in Arabidopsis thaliana ecotypes from near the limits of this species' latitudinal distribution in Europe. Leaf morphology, photosynthesis, and photoprotection were
The finding of acylcarnitines alongside free carnitine in Arabidopsis thaliana and other plant species, using tandem mass spectrometry coupled to liquid chromatography shows a link between carnitine and plant fatty acid metabolism. Moreover the occurrence of both medium- and long-chain
The methylation of myo-inositol forms O-methyl inositol (D-ononitol) when plants are under abiotic stress in a reaction catalyzed by myo-inositol methyltransferase (IMT). D-Ononitol can serve as an osmoprotectant that prevents water loss in plants. We isolated the IMT cDNA from Glycine max and found
We have identified cDNA clones encoding the two Mg chelatase subunits CHL I and CHL H from tobacco (Nicotiana tabacum) by screening a cDNA library with homologous cDNA fragments from Arabidopsis thaliana. A full-length Chl I cDNA clone encodes a peptide with 426 amino acids. The entire cDNA sequence
An Arabidopsis thaliana gene, At1g56550, was expressed in Pichia pastoris and the recombinant protein was shown to catalyse transfer of D-xylose from UDP-alpha-D-xylose onto methyl alpha-L-fucoside. The product formed was shown by 1D and 2D 1H NMR spectroscopy to be Me alpha-D-Xyl-(1,3)-alpha-L-Fuc,
The mitochondrial NADH:ubiquinone oxidoreductase complex (Complex I) is a large protein complex formed from both nuclearly and mitochondrially encoded subunits. Subunit ND1 is encoded by a mitochondrial gene comprising five exons, and the mature transcript requires four RNA splicing events, two of
The phytohormone abscisic acid (ABA) triggers an oscillation in the cytosolic Ca(2+) concentration, which is then perceived by unknown Ca(2+) binding proteins to initiate a series of signaling cascades that control many physiological processes, including adaptation to environmental stress. We report
The UV-B induced formation of thymine cis-syn cyclobutane dimer and related (6-4) photoproduct was monitored within DNA of cultured cells and plants of Arabidopsis thaliana. This was achieved using a sensitive and accurate HPLC-tandem mass spectrometry assay. It was found that the cyclobutane
