Project description:In this study, we used transcriptomic and hormonomic approaches to examine drought-induced changes in barley roots and leaves and its rhizosphere. By studying hormonal responses, alternative splicing events in barley, and changes in the rhizosphere microbiome, we aimed to provide a comprehensive view of barley drought-adaptive mechanisms and potential plant-microbe interactions under drought stress. This approach improved our understanding of barley adaptive strategies and highlighted the importance of considering plant-microbe interactions in the context of climate change.
Project description:Through 8 generations of selection, our group has developed a strain of rainbow trout that exhibits high growth rates on an economically and environmentally sustainable all plant protein, high-soy diet. The selected strain is resistant to development of soy-induced enteritis, an inflammatory intestinal pathology that occurs often in high-value carnivorous aquaculture species. To better characterize the physiological mechanism behind the superior performance of the selected strain we compared the homeostatic intestinal gene expression of the select strain to that of a commercial control line of trout. Samples were collected at early life stages known to be critical in the development of host-microbe interactions in the gut of rainbow trout. All female cohorts of both strains were reared alongside starting from eggs. Intestinal samples from 5 fish per group (2 fish strains; 2 developmental stages; 20 samples total) were used to generate mRNA selected stranded RNA-seq libraries for high throughput sequencing. Reads were quantified at the transcript level prior to evaluating differential transcript usage and differential gene expression between the two strains of trout and the developmental stages.

Project description:Comparative Transcriptome Analysis Reveals Molecular Evolution in the Carnivorous Utricularia
Project description:To explore mechanisms involved in the plant-microbe interactions, we proceeded with genome-wide transcriptome analysis of Arabidopsis roots incubated with E. coli Bl21 for 24 hours. Control plants did not receive E. coli.
Project description:Transcriptomics and molecular evolutionary rate analysis of the Bladderwort (Utricularia), a Carnivorous Plant with a Minimal Genome
Project description:Although some mechanisms are known how plant growth beneficial bacteria help plants to grow under stressful conditions, we still know little how the metabolism of host plants and bacteria is coordinated during the establishment of functional interaction. In the present work, using single and dual transcriptomics, we studied the reprograming of metabolic and signaling pathways of Enterobacter sp. SA187 with Arabidopsis thaliana during the change from free-living to endophytic host-microbe interaction. We could identify major changes in primary and secondary metabolic pathways in both the host and bacteria upon interaction, with an important role of the sulfur metabolism and retrograde signaling in mediating plant resistance to salt stress. Also, we studied the effect of SA187 endogenous compounds and its role on sulfur metabolism and consequently salt tolerance. These data should help future research in the field of beneficial plant-microbe interactions for developing sophisticated strategies to improve agriculture of crops under adverse environmental conditions. transcriptome of Arabidopsis thaliana organs with beneficial microbe, beneficial microbe endogenous compound, and ethylene precursor
