Powdery mildew, caused by the fungus Blumeria graminis (DC) Speer, is one of the most important foliar diseases of cereals worldwide. It is an obligate biotrophic parasite, colonising leaf epidermal cells to obtain nutrients from the plant cells without killing them. Syringolin A (sylA), a circular peptide secreted by the phytopathogenic bacterium Pseudomonas syringae pv. syringae, triggers a hypersensitive cell death reaction (HR) at infection sites when sprayed onto powdery mildew infected wheat which essentially eradicates the fungus. The rational was to identify genes whose expression was specifically regulated during HR, i.e. genes that might be involved in the switch of compatibility to incompatibility.<br></br>Powdery mildew-infected or uninfected plants were treated with syringolin two days after infection and plant material for RNA extraction was collected at 0.5, 1, 2, 4, 8, 12 hours after treatment (hat), resulting in an early (2 and 4 hat) and late pool (8 and 12 hat). Plant material that was uninfected prior to syringolin treatment was collected 8 and 12 hat (late pool of uninfected plant material), and 1 hat, respectively.

View SamplesXenopus laevis embryos were injected with alpha-amanitin to inhibit RNA polymerase II activity. Embryos were allowed to develop up to stage 10.5 (early gastrula, control and alpha-amanitin injected embryos) and subsequently collected for RNA isolation. The transcriptome profiles of alpha-amanitin injected and control embryos were compared.

View SamplesIn order to study the gene expression of pollen tubes as they grow in silk after pollination, we pollinated maize W22 silks with maize B73 pollen. The recent (2016) advent of the W22 genome assembly and annotation allows us to single out RNA-seq reads originating from the pollen tubes. B73 pollen, W22 silk and B73 seedling controls were sequenced as well.

View SamplesMyotonic dystrophy type 1 (DM1) is an autosomal dominant, CTG microsatellite expansion disease. Transcription of the CTG repeats gives rise to CUG repeat RNA with a toxic gain-of-function. The toxic CUG RNA sequesters the muscleblind-like (MBNL) family of RNA-binding proteins and disrupts their normal cellular function causing global mis-regulation of RNA processing. Multiple approaches have been developed to target the toxic RNA; these include, but are not limited to, displacing MBNL proteins from the CUG repeats, increasing MBNL protein levels or delivery of exogenous MBNL proteins, and blocking the transcription of the CUG repeats. From a screen of diamidine molecules, we previously identified furamidine as a promising lead molecule that was shown to reduce ribonuclear foci and rescue mis-splicing of splicing reporters in a HeLa cell model of DM1. We reported that treatment of the HSALR DM1 mouse model with furamidine partially rescued the Atp2a1 and Clcn1 mis-splicing events via RT-PCR. Here, using RNA-seq examine global splicing, we report that furamidine rescued over 70 mis-splicing events in the HSALR DM1 mouse model and minimally affected gene expression. Heptamidine, in comparison, rescued ~62 events but caused significant alterations in gene expression.

View SamplesWe performed RNA-sequencing on four groups of zebrafish larvae: control, Tg(Myc), Tg(Kras), Tg(Myc)&Tg(Kras) to analyze the expression of genes involved in the lipid-associated pathways.The results revealed high dynamic alterations in almost all aspects of lipid metabolism, among which, the expressions of genes involved in TG/DG/GP transformation and FA desaturation/elongation displayed intensive changes, in consistent with our observations in lipodomics profiling
