Project description:Perfluorobutanoic acid (PFBA) is a short-chain polyfluoroalkyl substance (PFAS) that is measurable in fish tissues and environmental matrices. Previous studies suggest that there are adverse effects on animal and human health following exposure to PFBA, however the mechanisms underlying the toxicity are not well characterized. This study measured biological responses (developmental, transcriptome, and behavioral responses) of zebrafish (wild-type AB strain, Danio rerio) following exposure to a range of PFBA concentrations (0.1-100 µl/L). To further elucidate putative mechanisms related to locomotor abnormalities by PFBA, RNA-seq was conducted. These data shed new mechanistic light onto the sublethal effects of lesser studied short chain perfluorinated chemicals.
Project description:To study the expression profiles of hexaploid wheat chromosome 3B genes during the life cycle of a wheat plant and establish a transcriptome atlas for this chromosome, deep transcriptome sequencing was conducted in duplicates in 15 wheat samples corresponding to five different organs (leaf, shoot, root, spike, and grain) at three developmental stages each. Strand-non-specific and strand-specific libraries were used to produce 2.52 billion paired-end reads (232 Gb) and 615.3 single-end reads (62 Gb), respectively.
Project description:Previous studies indicate that host phagocytes are regulated by a complex combination of pattern recognition receptors-signaling and miRNA inductions. We performed microRNA array to determine whether S. pneumoniae PfbA suppresses phagocytosis via miRNA inductions.
Project description:Many crop species have complex genomes, making the conventional pathway to associating molecular markers with trait variation, which includes genome sequencing, both expensive and time-consuming. We used a streamlined approach to rapidly develop a genomics platform for hexaploid wheat based on the inferred order of expressed sequences. This involved assembly of the transcriptomes for the progenitor genomes of bread wheat, the development of a genetic linkage map comprising 9495 mapped transcriptome-based SNP markers, use of this map to rearrange the genome sequence of Brachypodium distachyon into pseudomolecules representative of the genome organization of wheat and sequence similarity-based mapping onto this resource of the transcriptome assemblies. To demonstrate that this approximation of gene order in wheat is appropriate to underpin association genetics analysis, we undertook Associative Transcriptomics for straw biomass traits, identifying associations and even candidate genes for height, weight and width.
