Project description:The transcriptome of Leptosphaeria maculans was analyzed in mycelium and during oilseed rape (Brassica napus) leaf infection. The array probes were designed from gene models from the L. maculans whole genome annotation. One aim of this study was to verify the expression of the automatically annotated gene models in various conditions. Another goal was to monitor gene expression profiles during oilseed rape leaf infection and to highlight tissue-specific transcripts, e.g. in plant up-regulated transcripts, for further analyses. We performed 9 hybridizations (NimbleGen) with samples derived from mycelium and infected oilseed rape leaves. Samples from infected oilseed rape leaves were harvested 7 and 14 days post infection. Three replicates each. All samples were labeled with Cy3.

Project description:Purpose: Choline acetyltransferase (ChAT)-expressing epithelial cells are found in the upper and lower airways. In the trachea, they are referred to as brush cells. In the mouse nose two distinct populations of ChAT-eGFP+ cells had been previously described: a population of rare solitary chemosensory cells (SCCs) in the respiratory mucosa and a more abundant population of microvillous cells (MVCs) in the olfactory epithelium. Besides ChAT expression, SCCs share the expression of bitter taste receptors and signaling machinery with tracheal brush cells as well as close association with CGPR+ nerve fibers and an elongated shape. MVCs do not express bitter taste receptors, are not clearly associated with nerves and are smaller in size than SCCs. We have previously reported the transcriptional profile of tracheal ChAT-expressing brush cells but the transcriptional profile of nasal chemosensory ChAT+ epithelial cells has not been reported. Methods: In this study, we isolated nasal ChAT-eGFP+ cells by FACS from naïve ChAT(BAC)-eGFP mice with knockin of eGFP within a BAC spanning the ChAT locus, marking brush cells in the epithelium and performed transcriptome profiling using low input RNA sequencing. We sorted two distinct subsets of ChAT-eGFP+ epithelial cells from the nasal mucosa based on FACS ice and granularity characteristic: ChAT-eGFP+ EpCAM+ FSC/SSChigh (representing 5% of all ChAT-eGFP+ cells) and FSC/SSClow (representing 95% of all ChAT-eGFP+ cells), respectively. We compared them to unfractionated ChAT-eGFP- EpCAM+ epithelial cells. Results: Both nasal ChAT-eGFP subsets shared the core transcriptional profile of chemosensory cells from the intestine, trachea, gallbladder and thymus including the expression of Il25, Pou2f3, Trpm5, Avil, Plcb2 and transcripts of eicosanoid biosynthetic enzymes suggesting that most ChAT-eGFP+ cells in the nose belong to the chemosensory/tuft/brush cel family. The two subsets of nasal ChAT-eGFP+ cells differed in expression of taste receptors and taste receptor signaling machinery. Conclusions: Our study represents the first detailed analysis of the transcriptome of nasal ChAT-eGFP+ cells (brush cells) and identifies two subsets of nasal brush cells that share a core transcriptional signature but differ in expression of bitter taste receptors.

Project description:In this study, we evaluated the role of the gnathosomoa (mouthpart) in chemosensing of the most devastating honey bee parasite, Varroa destructor mite. Through transcriptomic analysis, we compared the expression of putative chemosensory genes between the body parts containing the main chemosensory organs (the forelegs), gnathosoma and the rest of the body devoid of these two body parts. Furthermore, we checked the presence of chemosensory-related transcripts in the proteome of the gnathosoma. Our comparative transcriptomic analysis revealed the presence of 83 transcripts with known characteristic conserved domains belonging to eight chemosensory gene families in the three Varroa transcriptomes. Among these transcripts, 11 were significantly upregulated in the mite’s forelegs, compared to 8 and 10 in the gnathosoma and body devoid of both organs, respectively. Whilst the gnathosoma and the forelegs share similar expression of some putative lipid carrier proteins, membrane-bound receptors, and associated proteins, they also differ in the expression profiles of some transcripts belonging to these protein families. This suggests two functional chemosensory organs that may differ in their chemosensory function according to specific characteristics of compounds they detect. Moreover, the higher expression of some chemosensory transcripts in the body devoid of forelegs and gnathosoma compared to the gnathosoma alone, may suggest the presence of additional function of these transcripts or alternatively presence of additional external or internal chemosensory organs. Insights into the functional annotation of a highly expressed gustatory receptor present in both organs using RNA interference (RNAi) are also revealed.

Project description:We performed a transcriptome analysis of interior spruce (Picea glauca x engelmannii) bark response to weevil (Pissodes strobi) feeding using 21.8K spruce microarray (that contains 21.8 thousand unique transcripts). This microarray study revealed a large rearrangement of the interior spruce bark transcriptome in response to weevil feeding involving differential expression of close to 20% of the studied transcriptome.
