Multi-omics Analyses Reveal Molecular Mechanisms of Potassium Deprivation Adaption in Wheat (Triticum aestivum L.)

Project description:This study evaluated the level of genetic variation among 543 wheat associations differing in K-deficiency tolerance at seedling and adult plant stages. Two of the 543 wheat associations, i.e. KN9204 and BN207, were identified as extreme K-deficiency tolerant and sensitive cultivars, respectively. We further conducted transcriptomic and metabolomics analyses using the roots of KN9204 and BN207 under normal or K-deficient conditions.Integrated analysis of gene expression and metabolite profiles revealed that dramatically more genes including those involved in ion homeostasis, cellular reactive oxygen species (ROS) homeostasis and glutamine synthetase pathways were induced in KN9204 as compared with BN207 under K-deficient conditions, which might indicate their unique roles in regulating plant K-starvation tolerance. These findings provided a better understanding of molecular responses of root adaptive strategies to K deprivation in wheat.

Biological control of Wheat take-all disease by earthworms

Project description:The take-all disease caused by the soilborne fungus Gaeumannomyces graminis var tritici (Ggt) is one of the most-studied and widespread root diseases worldwide. Here, we investigated the ability of the earthworm Aporrectodea caliginosa to induce take-all disease tolerance in Triticum aestivum.

Transcriptome of Triticum aestivum genotypes associated with resistance against the Wheat dwarf virus

Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare NGS-derived Triticum aestivum transcriptome (RNA-seq) profiling methods and to evaluate genotypes associated with resistance against the Wheat dwarf virus. Methods: Triticum aestivum mRNA profiles of genotypes associated with resistance against the Wheat dwarf virus were generated by deep sequencing, in four replicates, using Illumina. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. qRT–PCR validation was performed using TaqMan and SYBR Green assays. Conclusions: Our study represents the first detailed analysis of Triticum aestivum transcriptomes, with biologic replicates, generated by RNA-seq technology. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. Our results show that NGS offers a comprehensive and more accurate quantitative and qualitative evaluation of mRNA and miRNA content within a cell or tissue. We conclude that RNA-seq based transcriptome characterization would expedite genetic network analyses and permit the dissection of complex biologic functions.
