Differential gene expression in salicylic acid-deficient transgenic plants overexpressing StTGA2.1 after viral infection.

Project description:The general aim was to better understand the role of StTGA2.1 in plant immunity by transcriptional profiling of plants overexpressing the salicylic acid pathwas related TGA transcription factor StTGA2.1 after infection with potato virus Y (PVY). Potato non-transgenic cultivar Rywal (NT), Rywal-NahG (NahG), a transgenic line unable to accumulate SA due to salicylate hydroxylase expression, and a transgenic Rywal-NahG line inducibly overexpressing StTGA2.1 (TGA2.1-NahG) using the glucocorticoid-system, in which target gene expression can be controlled by external application of dexamethasone (DEX), were used. The leaves of three plants per genotype were infected with either PVY or mock-inoculum and subsequently treated with DEX. Additionally, three TGA2.1-NahG PVY-infected or mock-inoculated plants were not treated with DEX as control. After four days, PVY infection symtoms appeared as small regions of necrotic tissue called lesions. Tissue sections, containing lesions and their immediate surrounding area, were sampled, allowing us to focus on PVY-affected cells. Total RNA was isolated, DNase treated and sent for library prep and high-throughput sequencing.

analysis of npc48 overexpressing plants-Analysis of npc48 overexpressing plants.

Project description:rs07-02_npc48 - analysis of npc48 overexpressing plants - Identification of potential targets of the non-protein codding RNA npc48. - We have lines overexpressing npc48 that shhowed a leaf morphological phenotype (serrated leaves). The proportion of lines havin gthe phenotype is around 20% of total transformants. We wanted to compare the transcriiptome of npc48-overexpressing lines with and without phenotype together with a transformation control for an additional control.

wip overexpressing plants-Transcriptome analysis of WIP overexpressing plants

Project description:adt10-01_wip2 - wip overexpressing plants - Identification of genes induced or repressed by WIP genes - The objective is to identify genes responsible for the phenotypes observed in WIP overexpressing lines. WIP transcription factors are involved in reproductive and vegetative development by acting on the remodeling of various tissues. The WIP related processes have a major impact, in particular on reproduction (sex determination, fertilization, development of the seed). The way of action of these transcription factors is probably conserved, their effect depending only on their specificity of expression. Two WIP genes, NTT and TT1, was overexpressed in Arabidopsis thaliana. The objective is to compare the common deregulated genes (and in particular repressed) in the transcriptome of these two overexpressor lines, to highlight their mode of action and the way they act on the tissue in which they are expressed. Keywords: gene knock in (transgenic),normal vs transgenic comparaison

Gene expression in wild-type and transgenic plants overexpressing rice OsTOP6A1 gene

Project description:10-day-old wild-type and homozygous transgenic Arabidopsis seedlings (overexpressing rice topoisomerase 6 subunit A1; OsTOP6A1) grown under normal growth conditions were used for total RNA isolation. The 5 micrograms of each total RNA sample was processed for microarray analysis according to Affymetrix protocol. Experiment Overall Design: The experiment involves the study of differential gene expression in transgenic Arabidopsis seedlings overexpressing rice topoisomerase 6 subunit A1 (OsTOP6A1) cDNA as compared to wild-type.Three biological replicates for each sample were used for microarray analysis.

Transcription profiling by array of Arabidopsis transgenic plants overexpressing YFP and VND7-YFP

Project description:The Arabidopsis thaliana NAC domain transcription factor, VASCULAR-RELATED NAC-DOMAIN7 (VND7), acts as a master regulator for differentiation of xylem vessels. In order to identify a set of genes regulated by VND7, we carried out a microarray experiment with the Arabidopsis full-genome GeneChip array ATH1 (Affymetrix) for transgenic Arabidopsis roots overexpressing VND7. Experiment Overall Design: Total RNAs were isolated from roots of 5-day-old seedling of transgenic plants overexpressing YFP and VND7-YFP under control of Cauliflower mosaic virus 35S promoter. Three independent biological replicates were performed for each sample.
