Project description:Pharmacokinetic model of alkylresorcinols. Both plasma AR concentrations and urinary metabolites in 24-h samples showed a dose-response relation to increased AR intake, which strongly supports the hypothesis that ARs and their metabolites may be useful as biomarkers of whole-grain wheat and rye intakes.

Project description:We present a high-resolution network of gene expression during meiosis and its regulatory control elements in polyploid wheat. MeioCapture method (Shunmugam et al. 2018 BMC Plant Biology 18: 293) was used for isolating high-purity sporogenous archesporial columns of synchronized male meiocytes from wheat anthers in different meiotic stages. Total RNA extracted from three independent biological replicates per developmental stage of the meiocytes, as well as vegetative flag leaf, young leaves, and reproductive anthers and pollen, was sequenced using Illumina platform, generating 548 million paired-end short mRNA reads. Filtered reads were aligned to the wheat reference genome (IWGSC v1.0) using STAR. Transcript abundance was estimated using the RSEM (v1.3.3) and the IWGSC v1.1 annotation, and read counts and transcripts per million (TPM) values that normalize counts to a consistent number per library (1 million) to facilitate the comparison of relative expression across various samples were generated.

Project description:To profile the transcriptome of samples by “sample type (EV vs. Cell)”, “sex (Female vs. Male)”, and “treatment (0 vs. 120 vs 320 mg / dL)”. We performed gene expression profiling analysis using data obtained from RNA-seq of 18 EV samples and 18 cell samples in different treatment groups and sex.

Project description:To gain insights into the function and mechanism of Interleukin (IL)-18 in cancer cells, we conducted RNA-seq analysis to compare the gene expression profiles between IL-18 WT- and IL-18 D69A (IL-18 mutagenesis replacing aspartate (D) with alanine (A) at position 69)-overexpressing B16-F10 tumors. As expected, many genes were upregulated in IL-18 WT samples. Notably, transcripts related to many signaling pathways such as interferon signaling pathway were significantly enriched in samples expressing IL-18 WT.

Project description:The aim of this study was to examine the transcriptional changes that govern the primary nitrogen (N) limitation response in roots and the long-term effect of N limitation in the basal nodes, which may be associated with tiller suppression by N supply. The effect of biostimulant application on N limitation response was also examined by including plant treated and untreated with microalgae extract-based biostimulant. For this purpose, RNA-seq was conducted in roots of 15 days-old hydroponically grown wheat plants (treated and untreated with biostimulants) 24 h after the introduction of the plants to the N limitation and in basal nodes of 32 days-old wheat plants (treated and untreated with biostimulants) exposed to N limitation for 18 days. The two different N treatments were: High N (10 mM N) and Low N (0.1 mM N). In total, three biological replicates were included per treatment. RNA-seq was conducted in total RNA extracted from 3 basal node samples pooled together per biological replicate. In this study, the basal node is defined as the 0.5 cm of the main shoot base, which includes the apical meristem, lateral buds, leaf meristems etc.

Project description:Background: MicroRNAs regulate various biological processes in plants. Considerable data are available on miRNAs involved in the development of rice, maize and barley. In contrast, little is known about miRNAs and their functions in the development of wheat. In this study, five small RNA (sRNA) libraries from wheat seedlings, flag leaves, and developing seeds were developed and sequenced to identify miRNAs and understand their functions in wheat development. Results: Twenty-four known miRNAs belonging to 15 miRNA families were identified from 18 MIRNA loci in wheat in the present study, including 15 (9 MIRNA loci) first identified in wheat, 13 miRNA families (16 MIRNA loci) being highly conserved and 2 (2 MIRNAs loci) moderately conserved. In addition, fifty-five novel miRNAs were also identified. The potential target genes for 15 known miRNAs and 37 novel miRNAs were predicted using strict criteria, and these target genes are involved in a wide range of biological functions. Four of the 15 known miRNA families and 22 of the 55 novel miRNAs were preferentially expressed in the developing seeds with logarithm of the fold change of 1.0～7.6, and half of them were seed-specific, suggesting that they participate in regulating wheat seed development and metabolism. From 5 days post-anthesis to 20 days post-anthesis, miR164 and miR160 increased in abundance in developing seeds, whereas miR169 decreased, suggesting their coordinating functions in the different developmental stages of wheat seed. Moreover, eight known miRNA families and 28 novel miRNAs exhibited tissue-biased expression in wheat flag leaves, with the logarithm of the fold changes of 0.5～5.2. The putative targets of these tissue-preferential miRNAs were involved in various metabolism and biological processes, suggesting complexity of the regulatory networks in different tissues. Our data also suggested that wheat flag leaves have more complicated regulatory networks of miRNAs than developing seeds. Conclusions: Our work identified and characterised wheat miRNAs, their targets and expression patterns. This study is the first to elucidate the regulatory networks of miRNAs involved in wheat flag leaves and developing seeds, and provided a foundation for future studies on specific functions of these miRNAs.

Project description:Background: Waterlogging was one of the most serious abiotic stresses in wheat-growing regions of China. There were great differences in waterlogging tolerance among different wheat varieties, and the mechanism of waterlogging tolerance of wheat seeds during germination was unclear. Methods: In order to reveal the adaptability of wheat to waterlogging stress during germination, we analyzed the germination rate and anatomical structure of three wheat seeds, ‘Zhoumai 22’, ‘Bainong 207’ and ‘Bainong 607’. At the same time, Illumina sequencing technology was used to determine the transcriptome of these three wheat varieties during germination. Results: The results showed that there was no significant difference between the germination rate of ‘Bainong 207’ after 3 days of waterlogging treatment and that of the control seeds. However, under waterlogging stress, the degree of emulsification and degradation of endosperm cells was higher than that of the control treatment, and starch granules in endosperm were significantly reduced. Transcriptome data were obtained from seed samples (a total of 18 samples) of three wheat varieties under waterlogging and control treatment. A total of 2,775 differentially expressed genes (DEGs) were identified by comprehensive analysis. In addition, by analyzing the correlation between the expression levels of DEGs and seed germination rates in three wheat varieties under waterlogging stress, it was found that the relative expression levels of 563 and 398 genes were positively and negatively correlated with the germination rate of wheat seeds, respectively. The GO and KEGG analysis found that the difference in waterlogging tolerance of the three wheat varieties was related to the abundance of key genes involved in the glycolysis pathway, the starch and sucrose metabolism pathway, and the lactose metabolism pathway. The ethanol dehydrogenase (ADH) gene in the endosperm of ‘Bainong 607’ was immediately induced after a short period of waterlogging, and the energy provided by glycolysis pathway enabled the seeds of ‘Bainong 607’ to germinate as early as possible, while the expression level of AP2/ERF transcription factor was up-regulated to further enhance its waterlogging tolerance. Conclusions: In general, this study provided a deeper understanding of the mechanisms by which different wheat varieties respond to waterlogging stress during germination.
