Transcription profiling of Arabidopsis Umkirch-1/Umkirch-3 hybrid plants compared to siblings carrying a microRNA targeting the Umkirch-3 allele of At5g41750

ABSTRACT: Umkirch-1/Umkirch-3 hybrid plants (KB142-2) grown at 16 degreeC long day were compared with siblings carrying a microRNA targeting the Umkirch-3 allele of At5g41750. Plants were about 3 weeks old, and whole rosettes were harvested. Each sample is a pool of 8-10 individuals.

Epistatic interactions between genes are a major factor in evolution. Hybrid necrosis is an example of a deleterious phenotype caused by epistatic interactions that is observed in many intra- and interspecific plant hybrids. A large number of hybrid necrosis cases share phenotypic similarities, suggesting a common underlying mechanism across a wide range of plant species. Here, we report that approximately 2% of intraspecific crosses in Arabidopsis thaliana yield F1 progeny that express necrosis ...[more]

Transcriptomic effects of the expression in Arabidopsis of a TCP15-EAR fusion controlled by its own promoter (one-color experiment)

Project description:TCP proteins are transcription factors that participate in plant development (Martin-Trillo ad Cubas, 2010; Uberti-Manassero et al., 2013). Previous studies demonstrated that the Arabidopsis thaliana TCP protein TCP15 affects the development of leaves, stems and flowers (Kieffer et al., 2011; Uberti-Manassero et al., 2013). To obtain further insight into the molecular mechanisms involved in TCP15 action, we performed a transcriptional profiling of plants that express a repressor form of TCP15 under the control of the TCP15 promoter (P15::TCP15-EAR), previously described in Uberti-Manassero et al. (2012). For this purpose, gene expression was quantified in RNA extracted from complete rosettes of 25-day-old P15::TCP15-EAR plants and compared with that in RNA extracted from wild-type (Col-0) plants of the same age. Two genotype experiment: wild type vs. P15::TCP15-EAR plants. Biological replicates: 1 wild type replicate, 1 P15::TCP15-EAR replicate.

Comparative transcriptome profiling of Arabidopsis lyrata and Arabidopsis thaliana

Project description:Arabidopsis thaliana and Arabidopsis lyrata are two closely related Brassicaceae species, which are used as models for plant comparative biology. They differ by lifestyle, predominant mating strategy, ecological niches and genome organization. In order to explore molecular basis of specific traits, we performed RNA-sequencing of vegetative rosettes from both species. Additionally, we sequenced apical meristems and inflorescences of A. lyrata that allow for intra-specific transcriptome comparison in several major developmental stages. Arabidopsis lyrata and Arabidopsis thaliana aerial tissues were collected from mock treated plants, total RNA isolated and poly-A RNA populations sequenced

Transcription profiling of diurnal gene expression in Arabidopsis thaliana Col-0 rosette leaves

Project description:How do the transcript levels of leaf-expressed genes change in a normal day-night cycle? The interest is in genes that are regulated by the circadian clock and the diurnal component (i.e. light, metabolite changes). Plants were grown on soil in a 12/12 h light/dark rythm at 20Â°C day and night. 5 weeks after germination the rosettes of the non-flowering plants were harvested, 15 plants per sample. Plants were harvested at 6 timepoints every 4 hours beginning with the end of the night (still in darkness).

Transcription profiling of Arabidopsis diurnal gene expression in rosette leaves of the phosphoglucomutase mutant (Col-0)

Project description:How do transcript levels of leaf-expressed genes change in a normal day-night cycle of the phosphoglucomutase (pgm) mutant? The interest is in genes that are regulated by the circadian clock and the diurnal component (i.e. light, metabolite changes). Plants were grown on soil in a 12/12 h light/dark rhythm at 20Â°C day and night. 5 weeks after germination the rosettes of the non-flowering plants were harvested, 15 plants per sample. Plants were harvested in series at 6 times every 4 hours, beginning with the end of the night (still in darkness). Experiment Overall Design: A diurnal time series (8 times) was analyzed.

Transcription profiling of Arabidopsis leaf gene expression after growth under low light and low CO2

Project description:Internal sugar and light specific dependent regulation of leaf gene expression was addressed by changing [CO2] to lower than compensation point [CO2] in combination with light or prolonged darkness. Plants were grown on soil in a 12/12 h light/dark rhythm at 20Â°C day and night and under normal [CO2]. 5 weeks after germination, the above-ground rosettes of the non-flowering plants were harvested, 12 plants per sample. Plants were harvested 4hrs after the end of night (i) under low (< 50 ppm) [CO2] and 150 ÂµE fluorescent light , (ii) under normal [CO2] and light, and, (iii) under low [CO2] and prolonged darkness. The low [CO2] treatment started 30 min before the end of night and stopped with harvesting. Experiment Overall Design: 2 biological replicates of plants under 3 treatments (4hrs low CO2+light, 4hrs low CO2+prolonged darkness, and 4hrs normal CO2+light).

Transcriptome of Arabidopsis APS kinase null mutants

Project description:The aim of the experiment is to look at transcriptional changes in null mutants of APS kinase. There are four APS kinase isoforms in Arabidopsis, we are interested in the double mutant APK1/APK2, created by crossing two single salk lines. The transcriptomes of WT (Col-0) plants and the double knockout (ab) will be compared. The plants were grown under controlled environment conditions of 10h day, 14h night, 22 degrees centigrade, 60% humidity for five weeks. 10 whole rosettes were pooled for each replicate, there are three replicates for each genotype. Keywords: Expression profiling by array 6 samples were used in this experiment
