Accumulation of the coumarin scopolin under abiotic stress conditions is mediated by the Arabidopsis thaliana THO/TREX complex

Project description:Secondary metabolites are involved in the plant stress response. Among these are scopolin and its active form scopoletin, which are coumarin derivatives associated with reactive oxygen species scavenging and pathogen defence. Here we show that in Arabidopsis thaliana, scopolin accumulation can be induced in the root by osmotic stress and in the leaf by low temperature stress. A genetic screen for altered scopolin levels in Arabidopsis thaliana identified a mutant compromised for scopolin accumulation in response to stress; the lesion was present in a homologue of THO1, the product of which contributes to the THO/TREX complex. The THO/TREX complex contributes to RNA silencing, supposedly by trafficking precursors of small RNAs. Mutants carrying defective THO and RDR6 genes were impaired with respect to scopolin accumulation in response to stress, suggesting a mechanism based on RNA silencing like the transacting small interfering RNA pathway which requires THO/TREX and RDR6 function.

RST1 and RIPR connect the cytosolic RNA exosome to the SKI complex in Arabidopsis

Project description:The RNA exosome is a key 3’-5’ exoribonuclease with evolutionary conserved structure and roles. Its cytosolic functions require the co-factors SKI7 and the Ski complex. Here we demonstrate by co-purification experiments that the ARM repeat protein RESURRECTION1 (RST1) and RST1 INTERACTING PROTEIN (RIPR) connect the cytosolic Arabidopsis RNA exosome to the Ski complex. rst1 and ripr mutants accumulate small RNAs many of which are quality control siRNAs (rqc-siRNAs) produced by the postranscriptional gene silencing (PTGS) machinery when mRNA degradation is compromised. Indeed, quasi identical small RNA populations are observed in mutants lacking the RRP45B/CER7 subunit of the core exosome. This biochemical and genetic evidence supports a physical and functional link between RST1, RIPR and the RNA exosome. Our data reveal the existence of additional cytosolic exosome co-factors besides the known SKI subunits. Interestingly, RST1 is not restricted to plants, as homologues with a similar domain architecture exist in animals, including humans.

Multi-omics and Network Evaluation of Arogenate Dehydratase Knock-out Mutants in Arabidopsis thaliana

Project description:By knocking out genes encoding specific arogenate dehydrase (ADT) enzymes in Arabidopsis, variable reductions in lignin can be achieved. To understand how ADT composition affects plant phenotypes and biomolecular systems, we successfully constructed single and multiple ADT knockout (KO) mutants in Arabidopsis. Using these mutants, a multi-omics (metabolome, transcriptome and proteome) evaluation was conducted using GC- and LC-MS, RNA-Seq, and iTRAQ labeled LC-MS/MS technologies. Identifications include primary and secondary metabolites, transcripts, and proteins in leaf and stem samples taken at 4 weeks of age from 9 KO and wild-type (WT) lines.
