Transcription profiling by RNA-seq of seven tissues from Oryza sativa japonica Nipponbare

ABSTRACT: Expression in seven tissues from Oryza sativa L. ssp japonica Nipponbare was profiled using RNA-sequencing: callus, leaf, root, seed, shoot, panicle before flowering, and panicle after flowering. The original experiment examined gene expression in the seven tissues, and utilized the data both to compare gene expression patterns between retrogenes and their parents and to compare patterns of expression divergence between RNA-based duplicates and DNA-based duplicates Note: All samples in SRA were assigned the same sample accession (DRS000668). This is incorrect as there are different samples, hence “Source Name” was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.

Gene duplication occurs by either DNA- or RNA-based processes; the latter duplicates single genes via retroposition of messenger RNA. The expression of a retroposed gene copy (retrocopy) is expected to be uncorrelated with its source gene because upstream promoter regions are usually not part of the retroposition process. In contrast, DNA-based duplication often encompasses both the coding and the intergenic (promoter) regions; hence, expression is often correlated, at least initially, between D ...[more]

SWATH-MS quantitative analysis of proteins in the rice inferior and superior spikelets during grain filling

Project description:Modern rice cultivars have large panicle, however, yield potential of these cultivars is often not fully achieved due to the poor grain-filling of their late-flowering inferior spikelets (IS). Our earlier work suggests broad transcriptional reprogramming during grain filling and shows a difference in gene expression between IS and the earlier-flowering superior spikelets (SS). However, the links between the abundance of transcripts and their corresponding proteins are unclear. In this study, a SWATH-MS (sequential window acquisition of all theoretical spectra-mass spectrometry) -based quantitative proteomic analysis has been applied between SS and IS. A total of 304 proteins, ranging from cellular components to biological processes, were observed to be differentially expressed between IS and SS. Detailed gene ontology analysis indicated that several biological processes including photosynthesis, protein metabolism, and energy metabolism are differentially regulated. Further correlation analysis revealed that abundance of most of the differentially expressed proteins is not correlated to the transcript levels, indicating an extra layer of gene regulation which may exist during rice grain filling. These findings raise an intriguing possibility that these candidate proteins may be crucial in determining the poor grain-filling of IS. Therefore, we hypothesize that the regulation of proteome changes not only occurs at the transcriptional, but also at the post-transcriptional level, during grain filling in rice.

Oryza sativa strain:CL 161, CL 151 Transcriptome or Gene expression

Project description:Bacterial panicle blight caused by the bacterium Burkholderia glumae is an emerging disease of rice in the United States. Not much is known about this disease, the disease cycle or any source of disease resistance. To understand the interaction between rice and Burkholderia glumae, we used transcriptomics via next-generation sequencing (RNA-Seq) and bioinformatics to identify differentially expressed transcripts between resistant and susceptible interactions and formulate a model for rice resistance to the disease. There was a total of 36 tissue samples that included 2 rice genotypes (CL 151 and CL 161) Ã 2 treatment groups (water control and bacterium inoculated) Ã 3 time points Ã 3 biological replicates. Note: Samples in SRA were assigned the same sample accession. This is incorrect as there are different samples, hence âSource Nameâ was replaced with new values. Comment[ENA_SAMPLE] contains the original SRA sample accessions.

Flowering time genes Heading date 1 and Early heading date 1 together control panicle development in rice.

Project description:Although flowering time is often associated with plant size, little is known about how flowering time genes affect plant architecture. We grew four rice lines having different flowering time genotypes (hd1 ehd1, hd1 Ehd1, Hd1 ehd1 and Hd1 Ehd1) under distinct photoperiod conditions. By using genotype-treatment combinations that resulted in similar flowering times, we were able to compare the effects of flowering time genes on traits related to plant architecture. The results revealed that the combination of Heading-date 1 (Hd1) and Early heading date 1 (Ehd1) can reduce the number of primary branches in a panicle, resulting in smaller spikelet numbers per panicle; this occurs independently of the control of flowering time. In addition, expression of the Hd3a and Rice Flowering-locus T 1 (RFT1) florigen genes was up-regulated in leaves of the Hd1 Ehd1 line at the time of the floral transition. We further revealed that Hd1 and/or Ehd1 caused up-regulation of Terminal Flower 1-like genes and precocious expression of panicle formation-related genes at shoot apical meristems during panicle development. Therefore, two key flowering time genes, Hd1 and Ehd1, can control panicle development in rice; this may affect crop yields in the field through florigen expression in leaf.

A point mutation in the zinc finger motif of RID1/EHD2/OsID1 protein leads to outstanding yield-related traits in japonica rice variety Wuyunjing 7.

Project description:BACKGROUND:Flowering time, which is often associated with the length of the growth period in rice, determines the adaptability of a plant to various environments. However, little is known about how flowering-time genes affect panicle development and yield formation potential in rice after inducing the transition from vegetative growth to reproductive growth. RESULTS:To explore the relationship between floral induction and yield formation and the molecular mechanism of panicle development in rice, a novel mutant, ghd10, was identified from japonica variety Wuyunjing 7 plants subjected to ethyl methane sulfonate (EMS) treatment. The ghd10 mutant exhibited delayed flowering time, tall stalks and increased panicle length and primary branch number. Map-based cloning revealed that Ghd10 encodes a transcription factor with Cys-2/His-2-type zinc finger motifs. Ghd10 is orthologous to INDETERMINATE1 (ID1), which promotes flowering in maize (Zea mays) and is identical to the previously cloned genes Rice Indeterminate1 (RID1), Early heading date2 (Ehd2) and OsId1. Transient expression analysis of the Ghd10-GFP fusion protein in tobacco mesophyll cells showed that this protein is expressed in the nucleus. Ghd10 mRNA accumulated most abundantly in developing leaves and panicle structures, but rarely in roots. Expression analysis revealed that the expression levels of Ehd1, Hd1, RFT1, Hd3a and OsMADS15 decreased dramatically under both short-day and long-day conditions in ghd10. CONCLUSION:These results indicate that Ghd10, which encodes a promoter of flowering, influences plant height and panicle development by regulating the expression levels of some flowering-related genes, such as Ehd1, Hd1, OsMADS15 and others. The ghd10 allele is a useful resource for improvement of panicle traits in rice grown in tropical and low-latitude areas.

Genome-wide association and high-resolution phenotyping link Oryza sativa panicle traits to numerous trait-specific QTL clusters.

Project description:Rice panicle architecture is a key target of selection when breeding for yield and grain quality. However, panicle phenotypes are difficult to measure and susceptible to confounding during genetic mapping due to correlation with flowering and subpopulation structure. Here we quantify 49 panicle phenotypes in 242 tropical rice accessions with the imaging platform PANorama. Using flowering as a covariate, we conduct a genome-wide association study (GWAS), detect numerous subpopulation-specific associations, and dissect multi-trait peaks using panicle phenotype covariates. Ten candidate genes in pathways known to regulate plant architecture fall under GWAS peaks, half of which overlap with quantitative trait loci identified in an experimental population. This is the first study to assess inflorescence phenotypes of field-grown material using a high-resolution phenotyping platform. Herein, we establish a panicle morphocline for domesticated rice, propose a genetic model underlying complex panicle traits, and demonstrate subtle links between panicle size and yield performance.
