During seed germination, proteins are translated not only from mRNAs newly transcribed upon imbibition but also from long-lived mRNAs that are synthesized during seed maturation and stored in the mature dry seeds. To clarify the distinct roles of proteins translated from long-lived mRNAs and de novo transcribed mRNAs in germinating rice embryos, proteome analysis based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) combining the use of a transcriptional inhibitor was performed.

Rice perception of symbiotic arbuscular mychorrhizal fungi requires the karrikin receptor complex

Project description:In terrestrial ecosystems plants take up phosphate predominantly via association with arbuscular mycorrhizal fungi (AMF). We discovered that the loss of responsiveness to AMF in the rice deletion mutant hebiba is encoded by the alpha/beta fold hydrolase, DWARF 14 LIKE (D14L), which is one of the 26 deleted genes. It is a component of an intracellular receptor complex involved in the detection of the smoke-compound karrikin. On the basis of the early and pronounced hebiba mutant phenotype, we hypothesized that functional D14L is required for the perception of AM fungi prior to contact. Germinated spore exudates of AMF activate pre-contact plant responses. Therefore, we used RNAseq to monitor the transcriptional changes of hebiba and wild type roots in response to germinated spore exudates, and also karrikin, over the first 24 hours post treatment. WT seedlings were treated with GSE, Karrikin or a mock and iho seedlings with GSE or a mock. Root material was collected for sequencing at 0, 3, 6, 9, 12 and 24 hours. This gave a total of 27 samples (WT+Mock: 6, WT+GSE: 5, WT+Karrikin:5, iho+Mock:6, iho+GSE: 5).

Identification of Magnaporthe oryzae elicited small RNAs and expression profiles in resistant and susceptible rice cultivars

Project description:To identify blast pathogen elicited miRNAs, four sRNA libraries were constructed: 8749036, A library, susceptible rice cultivar Zhonger-Ruanzhan; 12157795, B library, mock-treated blast resistant line H4; 9937360, C library, blast-treated susceptible rice cultivar Zhonger-Ruanzhan; and 11138187 clean reads, D library, blast-treated blast resistant line H4. The Short Oligonucleotide Analysis Package (SOAP; Beijing Genomics Institute) matched 85.46% (A, 7476714), 79.35% (B, 9647324), 77.70% (C, 7721715) and 76.10% (D, 8476386) sRNA reads to the genome. After removing other RNA categories matched to NCBI Genbank, Rfam database, known rice miRNA precursor, repeat associated RNA and siRNA, the remaining reads: 1681359(A); 3829741(B); 3182403(C); and 3970132(D), were used for further novel miRNA prediction. Since some miRNAs were tissue-specific, time-specific or stress-induced, only 291, 210, 164 and 220 registered miRNAs were identified in libraries A, B, C and D respectively. Thirty-one (A, 9385 reads), 399(B, 41024 read), 351(C, 36622 reads) and 333(D, 38064 reads) unique sRNAs were projected to be candidate miRNAs. Examination of mock-treated rice cultivar, mock-treated blast resistant rice line H4, blast-treated susceptible rice cultivar, and blast-treated blast resistant rice line H4.

Digital gene expression analysis of 5 rice samples

Project description:To study the function of chromatin regulators in hybrid gene expression, the histone deacetylase gene OsHDT1 was over-expressed or inactivated by RNAi in an elite rice parent. Digital analysis of gene expression using high throughput sequencing technology revealed several differential gene expression patterns in the hybrid, including additivity, nonadditivity and overdominance, etc. Alteration of OsHDT1 levels affected many genes specifically in the hybrid. In addition, we show that increased OsHDT1 could suppress overdominance gene expression, providing evidence of overdominance gene action in heterosis. These results not only support the overdominance hypothesis to explain heterosis, but also provide evidence that variation in the levels of single trans-acting regulatory proteins such as chromatin factors is important to establish differential gene expression pattern in the hybrid. High throughput sequencing technology was used to analyse gene differencial expression of 15 days old rice seedling of 5 samples, MH63(MH), ZS97(ZS), SY63(SY,hybrids of MH and ZS), overexpression of OsHDT1 in SY(FU), RNAi of OsHDT1 in SY(FR).

29RNP kinase idetification - Identification and characterization of chloroplast casein kinase II from Oryza sativa (rice)

Project description:The 29-kDa RNA protein (29RNP), which was originally identified in rice etioplasts, has increased phosphorylation levels during de-etiolation. Here, using heparin-sepharose enriched fractions, we identified a chloroplast kinase that phosphorylated 29RNP. The chloroplast kinase phosphorylated the 29RNP and exhibited CKII biochemical characteristics in a kinase reaction test. Proteomic analysis of the chloroplast heparin-sepharose enriched fractions revealed the presence of 70 proteins, including both abundant proteins, such as plastid encoded polymerase subunits, and low-abundance proteins, such as APO2 and DAG. An inclusion list method using Fourier transform ion cyclotron resonance mass spectrometer ( FT-ICR LTQ MS ) was subsequently used to analyze the chloroplast heparin-sepharose enriched fractions. The 29RNP kinase was positively identified as a CKII alpha family protein by the presence of two unique peptides.

Proteomic and Phosphoproteomic Analyses Reveal Extensive Phosphorylation of Regulatory Proteins in Developing Rice Anthers

Project description:Anther development, particularly around the time of meiosis, is extremely crucial for plant sexual reproduction. Meanwhile, cell-to-cell communication between somatic (especial tapetum) cells and meiocytes are important for both somatic anther development and meiosis. To investigate possible molecular mechanisms involved in protein activities during anther development, we applied high-resolution mass spectrometry-based proteomic and phosphoproteomic analyses for developing rice (Oryza sativa) anthers around the time of meiosis (RAM). In total, we identified 4,984 proteins and 3,203 phosphoproteins with 8,973 unique phosphorylation sites (p-sites). Among those detected here, 1,544 phosphoproteins are currently absent in the Plant Protein Phosphorylation DataBase (P3DB), substantially enriching plant phosphorylation information. Mapman enrichment analysis showed that “DNA repair”, “transcription regulation” and “signalling” related proteins were over-represented in the phosphorylated proteins. Ten genetically identified rice meiotic proteins were detected to be phosphorylated at a total of 25 p-sites; moreover more than 400 meiotically expressed proteins were revealed to be phosphorylated and their phosphorylation sites were precisely assigned. 163 putative secretory proteins, possibly functioning in cell-to-cell communication, are also phosphorylated. Furthermore, we showed that DNA synthesis, RNA splicing and RNA-directed DNA methylation pathways are extensively affected by phosphorylation. In addition, our data support forty-six kinase-substrate pairs predicted by the rice Kinase-Protein Interaction Map, with SnRK1 substrates highly enriched. Taken together, our data revealed extensive protein phosphorylation during anther development, suggesting an important post-translational modification mechanism for protein activity.

Readthrough Events in Plants Reveal Unprecedented Plasticity of Stop Codons

Project description:Stop codon readthrough (SCR) has important biological implications but remains largely uncharacterized. Here, we identify 1,009 SCR events in plants using a proteogenomic strategy. Plant SCR candidates tend to have shorter transcript lengths and fewer exons and splice variants than non-SCR transcripts. Mass spectrometry evidence shows that stop codons involved in SCR events can be recoded as 20 standard amino acids, some of which are also supported by suppressor transfer RNA analysis. We also observe multiple functional signals in 34 maize extended proteins and characterize the structural and subcellular localization changes in the extended protein of BASIC TRANSCRIPTION FACTOR 3. Furthermore, the SCR events exhibit non-conserved signature and the extensions likely undergo protein-coding selection. Overall, our study not only characterizes that SCR events are commonly present in plants but also identifies the unprecedented recoding plasticity of stop codons, which provides important insights into the flexibility of genetic decoding.
