OsSAMS1 phosphorylated by GNP3, LC-MS/MS

ABSTRACT: Grain number per panicle critically determines rice yield.GNP3 encodes a MITOGEN-ACTIVATED PROTEIN KINASE KINASE KINASE 22 (OsMKKK22) that phosphorylates S-adenosyl-L-methionine synthetase 1 (SAMS1), triggering its degradation to suppress ethylene biosynthesis.To identify the residue(s) being phosphorylated by GNP3, we performed a liquid chromatography-tandem mass spectrometry (LC-MS/MS) analysis of recombinant SAMS1 incubated with GNP3.

A viral protein promotes host SAMS1 activity and ethylene production for the benefit of virus infection

Project description:Ethylene plays critical roles in plant development and biotic stress response. However, the mechanism of ethylene in host antiviral response remains unclear. Rice dwarf virus (RDV) triggers the ethylene production resulting in host susceptibility by enhancing the activity of S-adenosyl-L-methionine synthase (SAMS) in ethylene synthesis pathway. Our molecular and genetic data demonstrated that Pns11 specifically interacted with OsSAMS1 to enhance its enzymatic activity, resulting in increased production of ethylene in both Pns11 overexpressing and RDV-infected rice. Treatment of rice plants with ethylene precursor increased their susceptibility to RDV infection. More importantly, knockout of OsSAMS1 (CRISPR/Cas9) or blocking ethylene signaling in an ethylene-insensitive mutant (osein2) decreased susceptibility to RDV infection, and overexpression of OsSAMS1 or Pns11 increased susceptibility. In this study, we have analyzed the relationship between ethylene pathway response and RDV infection or OsSAMS1 and S11 transgene by the gene expression analysis through the RNA-seq.

Genome-wide Mapping of the Ozone-responsive Transcriptomes of Rice Panicle and Seed Tissues Reveals Novel Insight into their Regulatory Events

Project description:The ‘O3-responsive transcriptome’ behavior in the panicles and grains of rice plant was studied individually through high-throughput oligo-DNA microarray technique. Obtained results showed that O3 differentially regulated 620 and 130 genes in the panicles and grains separately, by at least two-fold changes. However, only five genes were found to be common in both the tissues, suggesting towards the tissue specific O3-sensitivity in rice plants. Among the O3-responsive genes, 176 and 444 genes were up- and down-regulated in rice panicle; whereas, 24 and 106 genes in rice grain, respectively. Further mapping onto various regulatory events revealed that, the majority of differentially expressed genes were mainly involved in signaling, hormonal, cell wall, transcription, proteolysis, and defense events. Many previously unknown O3-responsive novel genes were identified, including the brassinosteroid insensitive-1 receptor kinase, wall-associated kinase like receptor, calcium-dependent protein kinases, phosphatidylinositol kinases, G-protein components, ethylene insensitive-3, cellulose synthases, pectatelyase, etc. Inventory of 745 O3-responsive genes and their mapping will surely expand our knowledge on novel regulatory processes in both panicles and grains of rice; and, serve as a resource towards the designing of rice crops for future high-O3 world. Comparison between healthy rice plant panicles and ozone treated plant panicles (for 8 h) and seed (grain) of healthy rice plants and of rice plants grown under ozone for their lifeftime was performed. Three biological replicates (panicle or seed; pooled) were used, and dye-swaped.

Data on the peptide mapping and MS identification for phosphorylated peptide.

Project description:This article contains peptides mapping, mass spectrometry and processed data related to the research "Identification and quantification of the phosphorylated ovalbumin by high resolution mass spectrometry under dry-heating treatment" [1]. Fourier transform ion cyclotron mass spectrometry (FTICR MS) was used to investigate the specific phosphorylation sites and the degree of phosphorylation (DSP) at each site. Specifically, phosphorylated peptides were monitored through mass shift on the FTICR MS spectrum. DSP was evaluated through the relative abundance levels of the FTICR MS spectrometry. From these data, the calculation method of DSP was exemplified.

Clostridioides difficile phosphoproteomics shows an expansion of phosphorylated proteins in stationary growth phase

Project description:Phosphorylation is a post-translational modification that can affect both house-keeping functions and virulence characteristics in bacterial pathogens. In the Gram-positive enteropathogen Clostridioides difficile the extent and nature of phosphorylation events is poorly characterized, though a protein-kinase mutant strain demonstrates pleiotropic phenotypes. Here, we used an immobilized metal affinity chromatography strategy to characterize serine, threonine and tyrosine phosphorylation in C. difficile. We find limited protein phosphorylation in the exponential growth phase but a sharp increase in the number of phosphopeptides after the onset of stationary growth phase. Among the overall more than 1500 phosphosites, our approach identifies expected targets and phosphorylation sites, including the protein kinase PrkC, the anti-sigma-F factor antagonist (SpoIIAA), the anti-sigma-B factor antagonist (RsbV) and HPr kinase/phosphorylase (HprK).. Analysis of high-confidence phosphosites shows that phosphorylation on serine residues is most common, followed by threonine and tyrosine phosphorylation. This work forms the basis for a further investigation into the contributions of individual kinases to the overall phosphoproteome of C. difficile and the role of phosphorylation in C. difficile physiology and pathogenesis.

Ethylene production in Synechocystis sp. PCC 6803 promotes phototactic movement

Project description:Ethylene is a gaseous signal sensed by plants and bacteria. Heterologous expression of the ethylene-forming enzyme (EFE) from Pseudomonas syringae in cyanobacteria leads to the production of ethylene under photoautotrophic conditions. The recent characterization of an ethylene responsive signaling pathway affecting phototaxis in the cyanobacterium Synechocystis sp. PCC 6803 implies that biotechnologically relevant ethylene synthesis may induce regulatory processes which are not related to changes in the metabolism. Here we provide data that endogenously produced ethylene accelerates movement of cells towards light. Microarray analysis demonstrates that ethylene deactivates transcription from the csiR1/lsiR promoter which is under control of the two-component system consisting of the ethylene and UV-A-sensing histidine kinase UirS and the DNA-binding response regulator UirR. Surprisingly, only very few other transcriptional changes were detected in the microarray analysis providing no direct hints to possible bottlenecks in phototrophic ethylene production.
