Project description:Flavonoids are stress-inducible metabolites important for plant-microbe interactions. In contrast to their well-known function in initiating rhizobia nodulation in legumes, it is unclear whether and how flavonoids may contribute to plant stress resistance through affecting non-nodulating bacteria in the root microbiome. Here we show how flavonoids preferentially attracts Aeromonadaceae in Arabidopsis thaliana root microbiome and how flavonoid-dependent recruitment of an Aeromona spp. results in enhanced plant drought resistance.

Project description:For decades the tobacco plant has served as a model organism in plant biology to answer fundamental biological questions in the areas of plant development, physiology, and genetics. Due to the lack of sufficient coverage of genomic sequences, however, none of the expressed sequence tag (EST)-based chips developed to date cover gene expression from the whole genome. The availability of Tobacco Genome Initiative (TGI) sequences provides a useful resource to build a whole genome exon array, even if the assembled sequences are highly fragmented. Here, the design of a Tobacco Exon Array is reported and an application to improve the understanding of genes regulated by cadmium (Cd) in tobacco is described. From the analysis and annotation of the 1,271,256 Nicotiana tabacum fasta and quality files from methyl filtered genomic survey sequences (GSS) obtained from the TGI and ~56,000 ESTs available in public databases, an exon array with 272,342 probesets was designed (four probes per exon) and tested on two selected tobacco varieties. Two tobacco varieties out of 45 accumulating low and high cadmium in leaf were identified based on the GGE biplot analysis, which is analysis of the genotype main effect (G) plus analysis of the genotype by environment interaction (GE) of eight field trials (four fields over two years) showing reproducibility across the trials. The selected varieties were grown under greenhouse conditions in two different soils and subjected to exon array analyses using root and leaf tissue to understand the genetic make-up of the Cd accumulation. An Affymetrix Exon Array was developed to cover a large (~90%) proportion of the tobacco gene space. The Tobacco Exon Array will be available for research use through the Affymetrix array catalogue. As a proof of the exon array usability, we have demonstrated that the Tobacco Exon Array is a valuable tool for studying Cd accumulation in tobacco leaves. Data from field and greenhouse experiments supported by gene expression studies strongly suggested that the difference in leaf Cd accumulation between the two specific tobacco cultivars is dependent solely on genetic factors and genetic variability rather than on the environment.

Project description:Plant Topless-related 1 (TPR1), belonging to a family of transcriptional corepressors found across eukaryotes, contributes to immunity signaling in Arabidopsis thaliana and wild tobacco. We used chromatin immunoprecipitation and sequencing (ChIP-seq) of Arabidopsis TPR1-GFP expressing transgenic lines to characterize genome-wide TPR1-chromatin associations.

Project description:Rates of esophageal adenocarcinoma are rising globally, with risk factors including a range of genetic and environmental factors, including obesity, tobacco smoking, TP53 mutations, and Barrett’s esophagus, a proinflammatory condition which often occurs prior to developing adenocarcinoma. Interestingly, these factors also modulate the gastrointestinal microbiome. To better understand the linkage between the microbiome, inflammation, and development of esophageal adenocarcinoma, we integrated 16S and RNA sequencing data. We found several microbial taxa enriched in tumor samples which were correlated with predicted immune cell infiltration from RNA-seq data, including a decrease in megakaryocyte-erythroid progenitor cells with a concomitant increase in platelets. These data suggest dysbiosis of the intratumoral microbiome promotes development and production of platelets, which reveal alterations in the immune microenvironment of esophageal adenocarcinoma and suggest novel therapeutic targets.

Project description:We have previously reported that the responses of tobacco tissues treated with AaGlucan are similar to those for laminarin [1]. To better understand the overall responses and signaling pathways in tobacco, we have identified here AaGlucan and laminarin early response genes, using a custom 16K BY-2 microarray [2,3]. BY-2 cells were treated with laminarin or an AaGlucan-enriched fraction prepared from A. alternata 102 culture-medium and subjected to microarray analysis.

Project description:Recently we published a set of tobacco lines, expressing the Dacucus carota (carrot) DcLCYB1 gene, with accelerated development, increased carotenoid content, and plant yield. Due to this, expression of DcLCYB1 might be of general interest in crop species as a strategy to accelerate plant development and increase biomass production under adverse field conditions. However, to follow this path, a better understanding of the molecular basis of this phenotype is essential. Here, we combine OMICs (RNAseq, proteomics, metabolomics, and lipidomics) and stress experiments to advance our understanding on the broader effect of the LCYB expression on the tobacco genome and metabolism.

Project description:Long-term dietary intake influences the structure and activity of the trillions of microorganisms residing in the human gut, but it remains unclear how rapidly and reproducibly the human gut microbiome responds to short-term macronutrient change. Here we show that the short-term consumption of diets composed entirely of animal or plant products alters microbial community structure and overwhelms inter-individual differences in microbial gene expression. The animal-based diet increased the abundance of bile-tolerant microorganisms (Alistipes, Bilophila and Bacteroides) and decreased the levels of Firmicutes that metabolize dietary plant polysaccharides (Roseburia, Eubacterium rectale and Ruminococcus bromii). Microbial activity mirrored differences between herbivorous and carnivorous mammals, reflecting trade-offs between carbohydrate and protein fermentation. Foodborne microbes from both diets transiently colonized the gut, including bacteria, fungi and even viruses. Finally, increases in the abundance and activity of Bilophila wadsworthia on the animal-based diet support a link between dietary fat, bile acids and the outgrowth of microorganisms capable of triggering inflammatory bowel disease. In concert, these results demonstrate that the gut microbiome can rapidly respond to altered diet, potentially facilitating the diversity of human dietary lifestyles. RNA-Seq analysis of the human gut microbiome during consumption of a plant- or animal-based diet.
