Project description:Photoperiod is a circannual signal measured by biological systems to align growth and reproduction with the seasons. To understand the effect of photoperiod of gene expression in Arabidopsis thaliana in the absence of exogenous sugar under constant light intensity, we performed time course mRNA-seq analysis on 13-day old seedlings across three photoperiods with triplicates to identify photoperiod-regulated genes.

Project description:Plants respond to seasonal cues such as the photoperiod, to adapt to current conditions and to prepare for environmental changes in the season to come. To assess photoperiodic responses at the protein level, we quantified the proteome of the model plant Arabidopsis thaliana by mass spectrometry across four photoperiods. This revealed coordinated changes of abundance in the proteins of photosynthesis, primary metabolism and secondary metabolic processes such as pigment biosynthesis, consistent with higher metabolic activity in long photoperiods. Higher translation rates during the day than during the night likely contribute to these changes, but rhythmic RNA profiles will alter their effects. Photoperiodic control of protein levels might be greatest if high translation rates only coincide with high transcript levels in some photoperiods. We term this mechanism ‘translational coincidence’, mathematically model its components, and demonstrate its effect on the Arabidopsis proteome. Datasets from a green alga and a cyanobacterium suggest that this mechanism is general, contributing to the seasonal control of the proteome in many phototrophic organisms, and favouring RNA rhythms even for stable proteins.

Project description:In order to identify genes specifically involved in the photoperiodic control of the mobilisation programme for starch reserve in Arabidopsis thaliana transcription profiling was performed on the following genotypes Columbia wild type (Col-0), CO overexpressor (35S::CO), CO muntant (co-10), GBSSI mutant (gbs-1), aps1 mutant (aps1) and Columbia with sucrose. The different Arabidopsis thaliana genotype seedlings were cultivated in long day conditions (16 h day/ 8 h dark) at 22 C in controlled environment cabinets for two weeks. Samples were collected at ZT 4, immediately frozen in liquid nitrogen and processed.

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.

Project description:The induction of flowering by the photoperiodic pathway (i.e. an increase in daylength) involves the production of systemic signals that induce the transition to reproductive development. In order to evaluate the early events occurring in the roots during the photoperiodic induction of flowering, we harvested the roots of 7 week-old Col-0 Arabidopsis thaliana plants grown plants exposed to a single 22-hour long day. Control plants were maintained under 8-hour short days. Plants were grown in hydroponics and roots tissues were harvested 16 and 22 hours after the beginning of the light period.

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. Please view also related dataset GSE69077 (RNA-sequencing of heat stressed A. lyrata and A. thaliana plants).
