Project description:Purpose: Analyze changes in the transcriptome of Arabidopsis thaliana in response to chronic exposure to silver nitrate at 4 μg/mL concentration. Methods: mRNA was extracted from non-treated and silver nitrate-treated 14-day old Arabidopsis thaliana seedlings using the RNAeasy extraction kit (Qiagen). RNA-seq libraries (3 rep/treatment and 3 reps/control) constructed with the TruSeq Stranded mRNA Sample Preparation kit (Illumina) were paired-end sequenced (100-nt read length) on an Illumina Nova Seq6000 system. Reads were mapped to the A. thaliana TAIR10 reference genome sequence and transcript levels were analyzed using the softare CLC Genomics Workbench (version 20.0.4, Qiagen). Results: Chronic exposure of A. thaliana plants to silver nitrate caused a change in the abundance of transcripts: AT2G01520 and AT4G12550, but no measureable impact on the rest of the transcriptome. Conclusions: Exposure of A. thaliana to silver nitrate at 4 μg/mL has minor impact on the transcriptome.

Project description:Nitrate is the major source of nitrogen available for many crop plants and is often the limiting factor for plant growth and agricultural productivity especially for maize. Many studies have been done identifying the transcriptome changes under low nitrate conditions. However, the microRNAs (miRNAs) varied under nitrate limiting conditions in maize has not been reported. MiRNAs play important roles in abiotic stress responses and nutrient deprivation. Root is the organ that plants transport nitrate. we used the microarray systems to perform a genome-wide search to detect miRNAs responding to the chronic and transient nitrate limiting conditions in maize.

Project description:In maize, nitrate regulates root development thanks to the coordinated action of many players. In this study, the involvement of SLs and auxin as putative downstream components of the nitrate regulation of lateral root development was investigated. To this aim, the endogenous SL content of maize root in response to nitrate availability was assessed by means of LC-MS/MS and measurements of lateral root density in the presence of analogues or inhibitors of auxin and strigolactones were performed. Furthermore, un untargeted RNA-seq based approach was used to better characterize the participation of auxin and strigolacotones to the transcriptional signature of maize root response to nitrate. Our results suggested that N deprivation toughly induces zealactone and carlactonoic acid biosynthesis in maize root, to a higher extent if compared to P-deprived roots. Moreover, data on lateral root density led to hypothesise the existence of both auxin-dependent and auxin-independent effects of nitrate on LR development. In addition, the inhibition of SL biosynthesis seems to participate to the auxin-dependent induction of LR, but the involvement of further downstream unknown components cannot be ruled out.

Many studies have been done identifying the transcriptome changes under low nitrate conditions. However, the microRNAs (miRNAs) varied under nitrate limiting conditions in maize has not been reported. MiRNAs play important roles in abiotic stress responses and nutrient deprivation. Root is the organ that plants transport nitrate. we used the microarray systems to perform a genome-wide search to detect miRNAs responding to the chronic and transient nitrate limiting conditions in maize. MicroRNAs (miRNAs) are small, endogenous RNAs that are regulators of gene expression in plants and animals. And, miRNAs have been known for years to be important for phosphate, sulphate and copper deprivation responses in plants. In Arabidopsis, small RNA deep sequencing associated with nitrate response had been analyzed. However, information about the way by which miRNA are regulated by abiotic stresses in general and by low nitrate in particular is unavailable for maize. In this study, we used GeneChip® microarray systems to perform a genome-wide search to detect miRNAs responding to the chronic and transient nitrate limiting conditions in roots in maize.

Project description:Freshly harvested Arabidopsis seeds (ecotype Col0 obtained under 10 mM nitrate nutrition, referred to as C10) are dormant and do not germinate when sown on an agarose-based medium. This experiment was performed to analyze the genes that are differentially expressed in freshly harvested C10 seeds sown on agarose (dormant) versus freshly harvested C10 dry seeds (dormant) to analyze differential expression of genes during the first 6 hrs of imbibition of dormant seeds. Reference: Alboresi et al. Plant Cell Environ (2005) 28 : 500-512 - 16 DAP siliques were harvested from Col 0 plants grown on 10 or 50 mM nitrate or from G4 3 mutant grown on 10 mM nitrate in growth chambers.

Project description:Treatment with angiotensin converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) has been shown to have anti-inflammatory effects such as decreased growth factors and cytokines in animal models, this effect however, has not been investigated in kidney transplant recipients. We aimed to study the effect of ACEI or ARB treatment on intragraft gene expression profiles of transplant kidney biopsies using microarrays. Both groups had similar demographic characteristics in terms of age, race, sex, type of transplant, previous history of transplantation or acute rejection, panel reactive antibody levels, and immunosuppressive treatment. There were no differences in acute and chronic Banff allograft injury scores between the 2 Groups. Intragraft gene expression profiles of ACEI or ARB treated Group 2 biopsies showed decreased gene transcripts of interferon-gamma and rejection-associated transcripts (GRIT) and constitutive macrophage-associated transcripts (CMAT) compared to Group 1 biopsies. There were no statistically significant differences in expression of cytotoxic T cell (CAT), regulatory T cell (TREG), B-cell (BAT), natural killer cell (NKAT), or endothelial cell-associated transcripts (ENDAT) between the 2 Groups. Our data suggest that exposure to ACEI or ARB was associated with down-regulation of GRIT and CMAT. This anti-inflammatory effect of ACEI or ARB treatment could be an additional benefit in kidney transplant recipients. We identified 29 near normal biopsies with chronic sum allograft injury score (ct+ci+cv) ⤠3 for gene expression profiling comparing 2 groups; Group 1 (n=16), patients with no exposure of ACEI or ARB treatment and Group 2 patients (n=13) with exposure to ACEI or ARB at least 6 months prior to kidney biopsy. Biopsies with a diagnosis of acute or chronic rejection, recurrent or de novo glomerular disease, or polyoma nephropathy were excluded.
