Project description:In this study, we set to take advantage of Marchantias less complex signalling architecture to better understand how plants respond to environmental cues such as stress and time of the day, to modulate the expression of genes and biological pathways. To this end, we constructed an abiotic stress gene expression atlas of Marchantia comprising seven abiotic stresses (darkness, high light, cold, heat, nitrogen deficiency, salt, mannitol) and their pairwise combinations (e.g., cold + salt). We also measured gene expression at six timepoints of a day (12h light/ 12h darkness)
Project description:We present a transcriptomic atlas of abiotic stress tolerance in wheat. We employed a systems biology approach to study physiological, metabolomic and transcriptomic responses associated with heat, drought, salinity and their possible combinations. Our objectives were to (1) rank stress treatments based on the overall physiological and growth impacts, (2) identify the core sets of genes common to a particular stress type, (3) examine pathways that are uniquely expressed in the various stress combinations, (4) detect associations between phenotypic and transcriptomic responses, (5) suggest possible transcription factors for further characterization and use in improving wheat performance in multi-stress environments.
Project description:In order to elucidate the role of the single Marchantia B-GATA ortholog in response to high light intensities, a transcriptomic analysis of Marchantia polymorpha BoGa, Mpb-gata1 mutants and MpB-GATA1ox under high-ligh stress conditions was performed.
Project description:To identify interactors of Mpphot, we performed an immunoprecipitation assay using wild-type (WT) Marchantia plants and transgenic Marchantia plants expressing Mpphot-Citrine or free Citrine. The experiment was repeated twice.
Project description:In this study, we aim to present a global view of transcriptome dynamics during various abiotic stresses in chickpea. We generated about 252 million high-quality reads from eight libraries (control, desiccation, salinity and cold stress samples for roots and shoots) using Illumina high-throughput sequencing GAII platform. We mapped the reads to the desi chickpea genome for estimation of their transcript abundance in different tissue samples. The transcriptome dynamics was studied by differential gene expression analyses between stress treatment and control sample. We collected different tissue samples (root and shoot tissues of 10-day-old seedlings subjected to control (kept in water), desiccation (transferred on folds of tissue paper), salinity (transferred to beaker containing 150 mM NaCl solution) and cold (kept in water at 4 M-BM-1 1M-BM-0C) stress for 5 h. Total RNA isolated from these tissue samples was subjected to Illumina sequencing. The sequenced data was further filtered using NGS QC Toolkit to obtain high-quality reads. The filtered reads were mapped to annotated chickpea genome using TopHat and fragments per exon kilobase per million (FPKM) was calculated using Cufflinks software for each gene in all the sample to measure their gene expression. Differential expression analysis was performed using Cuffdiff software. The differentially expressed genes during various abiotic stress conditions were identified.

Project description:New RNA-seq data was generated to create a large-scale Seminavis robusta gene expression atlas profiling a wide-range of experimental conditions including life cycle stages and abiotic stressors. These stresses encompass among others changes in temperature and salt concentration, silica depletion, high light exposure, H202 and decadienal treatment.
