Project description:We performed a tranascriptomic analysis of Ler, ebs and shl-2 plants in order to reveal targets whose transcription is regulated by EBS and SHL. The analysis was performed in WT plants (Ler), as well as mutants plants in which the expression of EBS and SHL was previously shown to be null, namely ebs and shl-2 mutant. To perform this study, plants were grown for 18 days under short days (SD) conditions (8h light, 16h darkness) in MS solid media. Three independent biological samples were hybridized separately.

Project description:By RNA deep sequencing, around 11,000 genes were found to be differentially expressed in ebs shl lhp1 compared with wild type, and SHL and EBS, together with LHP1 and EMF1, co-regulate the expression of thousands of gene in Arabidopsis

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

Project description:Flowering in plants is a very dynamic and synchronized process where various cues including age, day-length, temperature and endogenous hormones fine-tune the timing of flowering for reproductive success. Arabidopsis thaliana is a facultative long day plant where long-day (LD) photoperiod promotes flowering. Arabidopsis still flowers under short-day (SD) conditions, albeit much later than LD conditions. Although, factors regulating the photoperiodic LD pathway have been extensively investigated, the SD pathway is much less understood. Here we identified a critical transcription factor called bHLH93 (basic Helix-Loop-Helix 93) that is essential to induce flowering specifically under SD conditions in Arabidopsis. bhlh93 mutants do not flower from primary meristem under SD conditions, but flowers similar to wild type under LD conditions. The late flowering phenotype is rescued by exogenous application of GA, suggesting that bHLH93 acts upstream of GA pathway to promote flowering. Double mutant studies showed that bhlh93 is epistatic to phyB and soc1 genes under SD conditions. bHLH93 is expressed at the meristematic regions and its expression peaks at 8 hours after dawn under SD conditions. As expected, the bHLH93 is localized in the nucleus. Taken together, these data suggest that bHLH93 is a key transcription factor necessary for Arabidopsis thaliana to evolve as a facultative plant.

Project description:The aim of this study was to analyze the impact of autotetraploidy on gene expression in Arabidopsis thaliana by comparing diploid versus tetraploid transcriptomes. In particular, this included the comparison of the transcriptome of different tetraploid A. thaliana ecotypes (Col-0 vs. Ler-0). The study was extended to address further aspects. One was the comparison of the transcriptomes in subsequent generations. This intended to obtain information on the genome wide stability of autotetraploid gene expression. Another line of work compared the transcriptomes of different diploid vs. tetraploid tissues. This aimed to investigate whether particular gene groups are specifically affected during the development of A. thaliana autotetraploids. Samples 1-8: Arabidopsis thaliana Col-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Col-0 seedlings. The experiment was carried out with pedigree of independently generated and assessed tetraploid Col-0 lines. Samples 9-12: Arabidopsis thaliana Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Ler-0 seedlings. The experiment was carried out with pedigree of independently generated and assessed tetraploid Ler-0 lines. Samples 13-24: Arabidopsis thaliana Col-0 tetraploid transcriptome. Transcriptional profiling and comparison of diploid vs. tetraploid Col-0 leaves (6th - 8th).

Transcriptional profiling and comparison of diploid vs. tetraploid Ler-0 leaves (6th - 8th). The experiment was carried out with pedigree of independently generated and assessed tetraploid Ler-0 lines. Samples 33-36: Arabidopsis thaliana Ler-0 tetraploid transcriptome. Transcriptional profiling and comparison of tetraploid vs. tetraploid Ler-0 seedlings from the second (F2) and third (F3) generation after induction, respectively.

Project description:Compare gene expression in the resting leaves of Arabidopsis thaliana WT with the mutants fou2 and tpc1-2. To analyse the contribution of the fou2 and tpc1-2 mutations in Arabidopsis thaliana to gene expression, transcript levels in the resting leaves of Arabidopsis were measured using 4 weeks-old plants grown in control conditions (long day).

Project description:Floral transition and flower development are regulated by numerous environmental and endogenous signals, which are integrated at a relatively small number of floral integrators, such as FLOWERING LOCUS T (FT) and SUPPRESSOR OF CONSTANS OVEREXPRESSION 1 (SOC1). Of the environmental factors, photoperiod is regarded the most important one in promoting floral transition in Arabidopsis thaliana and most labstrains will flower earlier under long day (LD) conditions than under short day (SD) conditions. Arabidopsis is therefore considered a facultative LD plant. To monitor gene expression changes during floral transition and early flower development plants were grown under SD (9 hr light, 15 hr dark) for 30 days. Plants were then shifted to LD (16 hr light, 8 hr dark) conditions to induce flowering. RNA was isolated from micro-dissected apical tissue harvested 0, 3, 5, and 7 days after the shift to LD and double-stranded cDNA was synthesized. Biotinylated cRNA probes were prepared and hybridized to the Affymetrix ATH1 array in duplicate (biological replicates). To study floral transition, we not only analyzed response of wildtype Landsberg erecta (Ler) plants, but also the effect of mutants in the flowering time genes CONSTANS (CO; co-2) and FT (ft-2). Early flower development was analyzed by comparing Col-0 wildtype plants with the meristem identity mutant lfy-12 (Col-0).
