Microarray analysis of virus-infected Brachypodium distachyon

ABSTRACT: We used Brachypodium distachyon (BD21) as a model grass to gain insight into the affected host molecular pathways upon infection of Panicum Mosaic Virus (PMV) together with its satellite virus, Satellite Panicum Mosaic Virus (SPMV). Brachypodium plants at 2-3 leaf stage were either mock inoculated or inoculated with PMV and PMV+SPMV. Total RNA was isolated from shoot tissues of control and treated plants and was subjected to microarray analysis.

sRNA-seq of Brachypodium distachyon roots inoculated with Serendipita indica (syn. Piriformospora indica)

Project description:We sequenced mRNA and small RNA (sRNA) profiles in the interaction between Brachypodium distachyon (Bd) and Serendipita indica (Si; syn. Piriformospora indica), at four (4) days post inoculation (DPI). sRNA sequencing reads of Si-colonized and non-colonized roots, as well as axenic fungal cultures were generated. Three biological samples of each were sequenced, with two technical replicates per sample (SE). Raw reads from sRNA sequencing were submitted to technical adapter trimming (Cutadapt) before upload.

Novel microRNAs uncovered by deep sequencing of small RNA transcriptomes in T. aestivum and B. distachyon

Project description:The small RNA transcriptomes of bread wheat (Triticum aestivum L.) and its emerging model (Brachypodium distachyon (L.) Beauv) were obtained by using deep sequencing technology. Small RNA compositions were analyzed in these two species. In addition to 70 conserved microRNAs (miRNA) from 25 families, 23 novel wheat miRNAs were identified. For Brachypodium, 12 putative miRNAs were predicted from a limited number of ESTs, of which one was a potential novel miRNA. Also, 94 conserved miRNAs from 28 families were identified in this species. Expression validation was performed for several novel wheat miRNAs. RNA ligase-mediated 5' RACE experiments demonstrated their capability to cleave predicted target genes including three disease resistant gene analogs. Differential expression of miRNAs was observed between Brachypodium vegetative and reproductive tissues, suggesting their different roles at the two growth stages. Our work significantly increases the novel miRNA numbers in wheat and provides the first set of small RNAs in Brachypodium distachyon. Keywords: Small RNA One wheat small RNA library (Tae) and two Brachypodium small RNA libraries (BdR and BdV) were sequenced.

Transcription profiling by array of Brachypodium response to increased ambient temperature in seedlings

Project description:Microarray analysis on Brachypodium distachyon seedlings was performed to determine the response of the transcriptome to changes in ambient temperature, including identification of marker genes that were up-regulated or down-regulated by a moderate increase in growth temperature. Wild-type Brachypodium (Bd21) seedlings were grown on MSR63 media without sucrose (Alves et al. 2009 Nature Protocols vol. 4 pp 638-649) in a short-day photoperiod (14 hr light/ 10 hr dark) at 17 ºC. As the third leaf was emerging, plants were transferred to 12 ºC for 48 hrs. Plants were then maintained at 12 ºC or transferred to one of two temperature treatments: constant 22 ºC or constant 27 ºC. Samples were collected before the shift (0 hr) and at 2 hr and 24 hr after the shift and immediately frozen in liquid nitrogen. For each harvest, two to three replicates were collected that each contained 3 seedlings.

A global profiling of uncapped mRNAs under cold stress reveals specific decay patterns and endonucleolytic cleavages in Brachypodium

Project description:PARE (parallel analysis of RNA ends) was performed to study the change of uncapped mRNAs before and after cold treatment in Brachypodium. Different change patterns were identified. We have provided a complete view of uncapped transcriptome under cold stress condition, which will deepen our understanding of gene expression regulation in cold stress response as well as cold stress response mechanism for monocot plants. The uncapped mRNA profiles of 12-day-old Brachypodium seedlings with and without cold treatment (4 M-BM-0C for 24 h) were generated by deep sequencing using Illumina GAIIx

Transcriptome sequencing at early stage infection of the wheat pathogen Zymoseptoria tritici reveals chromosomal differences in transcription patterns and host specific gene expression.

Project description:We have applied whole transcriptome profiling to infer genetic determinants of pathogenicity and host specialization in Z. tritici. Our data includes RNAseq data from early infection stages of a compatible (wheat) and a non-compatible host (Brachypodium distachyon). Overall transcription of AC genes is remarkably lower than genes on core chromosomes (CC) and only 40% of the genes are transcribed. We identify 31 AC and 1069 CC genes showing plant specific expression. In addition 21 CC genes are only upregulated in wheat supporting functional relevance in host specificity. We further explore the genomic composition and distribution of unique and paralogous genes in Z. tritici focusing on the evolutionary origin of AC genes. In contrast to previous studies we show that ACs mainly encode unique genes. Phylogenetic analyses suggest that rare duplication events in the Z. tritici genome precede diversification of Zymoseptoria species and demonstrate that ACs have been maintained in the genome of Zymoseptoria over long evolutionary times. Examination of gene expression at 3 different growth condition of the wheat pathogen Z. tritici.

RNA-Seq of Brachypodium distachyon callus treated with methyl-jasmonate

Project description:The aim was to determine the changes in cell wall composition and transcriptome changes following treatment with the stress hormone precursor methyl jasmonate (MeJA) in the model grass Brachypodium distachyon. The correlation between transcript changes and cell wall composition changes allowed identification of candidate genes responsible for grass-specific features of the cell wall that are specifically changed in response to MeJA.

Rat Semi-Circular Canal Duct Gene Expression Studies

Project description:The goal was to screen for the expressed genes in Semi-Circular Canal Duct (SCCD) that are related to ion transport and its regulation. The objective was to discover which genes changed expression levels in response to glucocorticoids. Keywords: drug response Primary cultures were incubated for 24 hours in the presence or absence of 100 nM dexamethasone. Four independent cultures from each group were processed for total RNA and submitted for gene array analysis. Although two Samples out of four in each group were done at different time points, we found that there was not much variation between the datasets (by cluster analysis).
