Combining peak- and chromatogram-based retention time alignment algorithms for multiple chromatography-mass spectrometry datasets

ABSTRACT: Spring wheat (Triticum aestivum L.) was grown in a free-air carbon dioxide (CO2) enrichment (FACE) field experiment. Grain and biomass yield and its components were determined at maturity and the grain metabolome was analysed by gas chromatography-mass spectrometry (GC-MS) for elevated and ambient CO2 (537 versus 409 μl/l) concentration for samples grown in two successive years (2005, 2006).

<h4>Background</h4>Modern analytical methods in biology and chemistry use separation techniques coupled to sensitive detectors, such as gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS). These hyphenated methods provide high-dimensional data. Comparing such data manually to find corresponding signals is a laborious task, as each experiment usually consists of thousands of individual scans, each containing hundreds or even thousands of distinct signa ...[more]

RNAseq of roots and leaves of tender wheat (Triticum aestivum cv. Chinese Spring) during interaction with plant-growth-promoting rhizobacteria Azospirillum brasilense sp245 and Burkholderia graminis C4D1M

Project description:We monitored the transcriptomic response of roots and leaves of Triticum aestivum (cv Chinese Spring) at 2 months following the root inoculation by Azospirillum brasilense sp245 or Burkholderia graminis C4D1M. Plants were grown in pot containing a solid substrate (sand+soil) and 3 plants per pot, conditions in triplicates, in greenhouse conditions, and inoculated at seedling stage with OD 1 washed bacterial culture.

Drought stress in Wheat at grain filling stage

Project description:To provide a global study of transcriptome changes under drought stress, the gene expression levels of a durum wheat genotype (Triticum durum Desf. cultivar Creso) and two bread wheat genotypes (Triticum aestivum L. cultivar Chinese Spring -CS- and its deletion line CS_5AL-10) were investigated. The 5A chromosome deletion line (5AL-10) lacks the distal part (43%) of the long arm of chromosome 5A. Each genotype was subjected to two different levels of water stress at the grain filling stage. After anthesis, three different levels of soil water content (SWC) were induced as described below: control (CTRL; SWC=28%), moderate stress (MS; SWC=18%), and severe stress (SS; SWC=12.5%). For each sample, three biological replicates were performed, for a total of 27 hybridizations. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Alessio Aprile.

Light effect on the hormonal and transcriptional status of winter and spring wheat plants during cold hardening

Project description:The effect of light during the development of freezing tolerance was studied in winter wheat (Triticum aestivum L. var. Mv Emese) and spring wheat variety Nadro. Ten-day-old plants were cold hardened at 5°C for 12 days either under normal (250 mmol m-2 s-1) or low light (20 mmol m-2 s-1) conditions.

Genome interplay in the grain transcriptome of hexaploid bread wheat

Project description:Allohexaploid bread wheat (Triticum aestivum, L.) provides ~ 20% of calories consumed by humans. Hitherto lack of genome sequence for the three homoelogous and highly similar bread wheat genomes (A, B and, D) impeded expression analysis of the grain transcriptome. We used novel genome information to analyze the cell type specific expression of homeologous genes in the developing wheat grain.

Transcriptomic and physiological response of durum wheat grain to short period of heat stress at the early grain-filling stage

Project description:Wheat is one of the most significant crops in terms of human consumption in the world. In a climate change scenario, extreme weather event such as heatwaves will be more frequent especially during the grain-filling (GF) stage and could affect grain weight and quality of crops. Molecular mechanisms underlying the response to short heat stress (HS) have been widely reported for the hexaploid wheat (Triticum aestivum) but the regulatory heat stress mechanisms in tetraploid durum wheat (Triticum turgidum ssp. durum) remain partially understood. In this work, we performed a transcriptomic analysis of durum wheat grains to HS during early GF to identify key HS response genes and their predicted regulatory networks under glasshouse conditions.

RNAseq of roots and leaves of tender wheat (Triticum aestivum cv chinese Spring) during interactions with mycorhizal fungi (Funneliformis mossae) with and without a pathogen attack by Xanthomonas translucens

Project description:We monitored by RNAseq the transcriptomic response of roots and leaves of Triticum aestivum cv chinese Spring during a long term interaction with Funneliformis mossae (2 months) with or without a pathogen infection by infiltration of Xanthomonas translucens CFBP 2054. The control condition of roots and leaves wheat without mycorhizal fungi is in E-MTAB-5891 (material produced simultaneously and treated at the same time).
