Project description:ra06-05_potyvirus-ecotypes - arabidopsis ecotypes - Common and specific genes deregulated in response to various potyviruses in different Arabidopsis genetic backgrounds. - Four different Arabidopsis ecotypes were inoculated with one Potyviruse. About 4 weeks after sowing, the 6 expanded leaves plants were inoculated with the different viruses or were mock-inoculated. Seven days after inoculation, inoculated leaves were collected, RNA was extracted and virus infection controlled. RNA fron infected plants was then used for microarrays hybridization. Three biological repeat have been done and two dye-swap. Keywords: normal vs disease comparison
Project description:We have used a strain of Tobacco etch potyvirus (TEV) experimentally adapted to Arabidopsis thaliana ecotype Ler-0 to infect a set of seven A. thaliana plant ecotypes(Col-0, Ei-2, Wt-1, ler-0, Oy-0, St-0). Each ecotype was inoculated with the same amount of the virus. Using commercial microarrays containing probes Arabidopsis thaliana ssp. Col-0 plant transcripts, we explored the effect of viral infection in the plant transcriptome This microarray can be useful to study gene activity of Arabidopsis thaliana associated with response to virus infection. For ecotypes ST-0, Wt-1, Ler-0, Di-2 there are five biological replicates and for ecotype Oy-0 there are three. As control we used four technical replicates of each ecotype, but five for Ler-0. Rows and columns are numbered as scanned by a GenePix Scanner (barcode on the bottom, DNA on the front surface).

Project description:Belonging to the Carmovirus family, Turnip crinkle virus (TCV) is a positive-strand RNA virus that can infect Arabidopsis. Most Arabidopsis ecotypes are highly susceptible to TCV, except for the TCV resistant line Di-17 derived from ecotype Dijon. Previous studies showed that many of the stress related genes have changed significantly after TCV infection. Besides the virus-triggered genes, small RNAs also play critical roles in plant defense by triggering either transcriptional and/or post-transcriptional gene silencing. In this study, TCV-infected wildtype Arabidopsis thaliana and dcl1-9 mutant plants were subjected to transcriptome and small RNA analysis to investigate the role of DCL1 in virus defense network.

Project description:Fe deficiency stimulates a coordinated response involving reduction, transport and redistribution of Fe in the roots. The expression of genes regulated by Fe deficiency in the two contrasting Arabidopsis thaliana ecotypes, Tsu-1 and Kas-1, shows that different ecotypes can respond in diverse ways, with different Fe regulated overrepresented categories. We use microarrays to analyze the Fe deficiency responses of contrasting Arabidopsis thaliana ecotypes (Tsu-1 and Kas-1).
Project description:Seedlings of 35 different Arabidopsis thaliana ecotypes were compared. Triplicates were performed of 10 ecotpyes, single arrays of 25 ecotypes.
