Expression data from Y12-3 and A24-39 roots

Project description:Roots adaptation to drought stress was analyzed using transcriptome and metabolomics profiles in two wild emmer wheat (Triticum turgidum ssp. dicoccoides) genotypes: Y12-3 (drought resistance) and A24-39 (drought susceptible). Roots samples of Y12-3 and A24-39 genotypes grown under well-watered (control) and water-stressed (7 days of withholding water) were collected for RNA extraction and hybridization on Affymetrix wheat microarrays chip.

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.

Expression profiling of grass-clump dwarf in synthetic hexaploids from triploid hybrids crossed between tetraploid wheat and Aegilops tauschii

Project description:We have employed whole genome microarray expression profiling as a discovery platform to identify genes to alter the transcript accumulation levels in grass-clump dwarf lines, which are synthetic hexaploid lines from triploid hybrids crossed between tetraploid wheat (Triticum turgidum ssp. durum cv. Langdon or T. turgidum ssp. carthlicum) and diploid wheat progenitor Aegilops tauschii (KU2025). No up-regulation of defense-related genes was observed under the normal temperature, and down-regulation of wheat APETALA1-like MADS-box genes, considered to act as flowering promoters, was found in the grass-clump dwarf lines. Together with small RNA sequencing analysis of the grass-clump dwarf line, unusual expression of the miR156/SPLs module could explain the grass-clump dwarf phenotype. Expression patterns were compared between the three synthetic hexaploid lines showing the wild-type phenotype (as a reference) and grass-clump dwarf. Total RNA samples were isolated from crown tissues of the plants grown at 24Â°C under long day (18-h light and 6-h dark) condition for 8 weeks. Two independent experiments were conducted in each exprement.

Transcriptional response of durum wheat roots and leaves to continuous chromium stress

Project description:Chromium (Cr) is a highly toxic heavy metal for both mono and dicot plants, causing severe cellular damage and disturbances in plant growth, development, and reproduction. Its phytotoxicity results in serious changes in plant physiology, gene expression, and at a transgenerational level in genomic DNA methylation. Herein, transcriptional responses of durum wheat (Triticum turgidum L.) to continuous and basal Cr stress were explored in roots and leaves by RNAseq analysis. Plants cultivated in a hydroponic system supplemented with 2.5 and 10 µM Cr were compared with control plants through transcriptomic analysis after 50 days and for the biomass accumulation and seed yield after senescence.

Expression data from Triticum aestivum L. roots

Project description:To better understand the regulatory mechanisms of water stress response in wheat, the transcript profiles in roots of two wheat genotypes, namely, drought tolerant 'Luohan No.2' (LH) and drought susceptible 'Chinese Spring' (CS) under water-stress were comparatively analyzed by using the Affymetrix wheat GeneChip®. A total of 3831 transcripts displayed 2-fold or more expression changes, 1593 transcripts were induced compared with 2238 transcripts were repressed, in LH under water-stress; Relatively fewer transcripts were drought responsive in CS, 1404 transcripts were induced and 1493 were repressed. Comparatively, 569 transcripts were commonly induced and 424 transcripts commonly repressed in LH and CS under water-stress. 689 transcripts (757 probe sets) identified from LH and 537 transcripts (575 probe sets) from CS were annotated and classified into 10 functional categories, and 74 transcripts derived from 80 probe sets displayed the change ratios no less than 16 in LH or CS. Several kinds of candidate genes were differentially expressed between the LH and CS, which could be responsible for the difference in drought tolerance of the two genotypes. Two common wheat (Triticum aestivum L.) cultivars, Luohan No.2 (LH) and Chinese Spring (CS), were used for this study. Seedlings at the two leaf stage were stressed by cultured in PEG solutions for 6h, and some other seedlings were cultured in tap water as control. Root samples of LH and CS at 6h after the stress treatment and untreated control were prepared for microarray analysis.
