Protection of teleomere1b safeguards the Arabidopsis genome by regulating ROS homeostasis

ABSTRACT: Proximity labeling proteomics samples generated using TurboID fused to AtPOT1b or AtPOT1a in Arabidopsis thaliana. Six-day-old seedlings expressing POT1b-TurboID or POT1a-TurboID and corresponding TurboID-only controls were grown on half-strength MS medium with or without sucrose. Seedlings were treated with 250 uM biotin for 1 hour, followed by streptavidin-based enrichment of biotinylated proteins and LC-MS/MS analysis. Each condition includes biological replicates. Raw files correspond to individual LC-MS/MS runs for each genotype and growth condition.

The interaction between glucose and cytokinin signal transduction pathway in Arabidopsis thaliana

Project description:Columbia (Col) seeds were sown on half-strength Murashige and Skoog (MS) medium, supplemented with 1% sucrose and 0.8% agar and grown vertically in culture room conditions. The 5-d-old homogenous seedlings were washed five times with sterile water and lastly with liquid half strength MS medium without sugar to remove residual exogenous sugar. In order to deplete internal sugars seedlings were grown in sugar free liquid half strength MS medium for 24 h in dark. Thereafter, the seedlings were treated with half-strength MS medium containing 0% G, 0% G + 1 uM BAP, 3% G, and 3% G + 1 uM BAP for 3 h in dark. RNA was extracted and microarray analysis was performed. Please note: G stands for glucose and BAP stands for 6-Benzylaminopurine (cytokinin)

Transcript analysis under calcium deficiency in 6 day old Marchantia polymorpha wildtype (Tak-1) and Gβ-null mutant (gpb1-2) gemmalings and inter-species comparison of M. polymorpha, Arabidopsis and lettuce under calcium deficiency

Project description:Calcium deficiency response in liverwort, Arabidopsis and lettuce: (1) Marchantia polymorpha: M. polymorpha wildtype and Gβ-null mutant plants (Tak-1, gpb1-2) were grown in control liquid Yamagami media (2 mM Ca) for 6 days. For RNA-seq experiments, 6 day old gemmalings were transferred to calcium deficiency (0 mM Ca) media. Samples were collected at 48 h after the transfer. The transcriptomic profiles were collected from two independent batches. In total four biological replicates were used for each condition and each genotype for a total of 16 samples. (2) Arabidopsis thaliana: For Arabidopsis RNA-seq experiment, 6-day old seedlings grown on ½ strength MS media with sucrose were transferred to Yamagami media with 2 mM or 0 mM CaCl2 and treated for 7 days. (3) Lactuca Sativa: For lettuce RNA-seq, 4-day old seedlings grown on water agar (1%) were transferred to Yamagami media with 2 mM or 0.15 mM CaCl2 and treated for 7 days. In total four and three biological replicates were used for each condition for a total of 8 and 6 samples respectively for Arabidopsis and lettuce.

Transcription profiling of Arabidopsis dark grown seedlings response to 6h-long treatment with 90 mM sucrose

Project description:Dark grown Arabidopsis seedlings (Columbia gl1) were grown in the dark at 23Â°C for 4 days before adding 90 mM sucrose for 6h. Experiment Overall Design: Arabidopsis thaliana ecotype Columbia glabra (gl1-1) was used in this study. Seeds were sterilized with diluted bleach (10 min incubation in 1.7% sodium hypochlorite, rinsing and washing thoroughly in sterile water), and incubated in 2.5 ml liquid growing medium [Murashige-Skoog (MS) half strength solution] in 6-well plates (fully aerobic, with shaking). Plates were incubated in the darkness at 4Â°C for 2 days and finally transferred to 23Â°C for 4 days before the sugar treatments (with 90 mM sucrose, lasting 6h). Two independent, replicated experiments were performed for sucrose treatments. Each independent experiment consisted of four replicated seedlings cultures, pooled after RNA extraction. Experiment Overall Design: AIR EXPERIMENT 1: Control without added sucrose Experiment Overall Design: AIR EXPERIMENT 2: Control without added sucrose Experiment Overall Design: Sucrose 90 mM, 6h treatment in the dark, Biological Replicate 1 Experiment Overall Design: Sucrose 90 mM, 6h treatment in the dark, Biological Replicate 2

Transcriptomics Analyses of tobacco leaves and roots sample during water-deficit

Project description:Microarray experiments were performed on the roots and leaves samples seperately using custom based Nimblegen platform (12plex). This is a time-course study. The plants were grown in controlled growth chamber condiditons. The seeds were sown in sterile petri plates with modified half-strength MS agar medium. The seedlings were then aseptically transferred into sterile polycarbonate container with half-strength MS liquid medium. Seedlings were grown for 2 weeks in an incubator set at 25 oC with constant light and subjected to dehydration for 20min, 40min, 1hr, 2hrs, and 4hrs.

Transcriptome analysis of pho3

Project description:The aim of this proposal is to understand the impact of the pho3 mutation on the transcriptome.The mutant pho3 was isolated on the basis of a failure to induce acid phosphatase activity in roots in response to low Pi. The pho3 mutant had a P deficient phenotype in vitro and in the leaves of soil grown pho3 plants the total P content was again reduced. pho3 exhibited a number of characteristics normally associated with low-P stress, including severely reduced growth, increased anthocyanin content and starch accumulation. pho3 was shown to have an absolute requirement for exogenous sucrose as pho3 seedlings were arrested in early seedling development on sucrose-free medium and was unaffected by Pi-availability. pho3 was found to be insensitive to high concentrations of exogenous sucrose (10%) but was sensitive to glucose. pho3 also exhibited reduced sensitivity of seed germination to exogenous ABA (abi-phenotype), a response which has been linked to sucrose insensitivity in both sugar-sensing and ABA mutants. Two developmental stages have been selected on the basis of the physiological characterisation of pho3. Seedlings (1.02; 2 rosette leaves) grown in agar and compost-grown plants (3.90; rosette growth complete). Agar will be supplemented with 1% sucrose and 1/2 strength MS; plants will be grown under a 16 h light/8 h dark cycle. Comparisons will be made between pho3 and Wassilewskija (the genetic background of the mutant) at each stage.

Genome wide analysis of glucose brassinosteroid interaction in Arabidopsis

Project description:Arabidopsis thaliana seeds after imbibition were inoculated in ½ MS medium supplemented with 0.8% agar and 1% sucrose. Once the plant material was uniformly germinated, the experimental conditions were applied. 5d old light-grown uniformly germinated seedlings were washed seven times with sterile water with last wash given by ½ MS liquid medium without sucrose to remove residual exogenous sugar and the plant material was kept in ½ MS liquid without sucrose in the dark for all subsequent steps. Cultures were shaken at 140 rpm at 22oC for 24 h and then 3 h treatment was given with liquid ½ MS without glucose and liquid ½ MS supplemented with BR (0.1 ?M EBR), glucose (3%), glucose (3%) + BR (0.1 ?M EBR). Seedlings were harvested after 3h and preceded for RNA isolation and Microarray analysis.

Once the plant material was uniformly germinated, the experimental conditions were applied. 5-d-old, dark-grown seedlings were washed seven times with sterile water followed by a wash with ? X MS liquid medium without sucrose to remove residual exogenous sugar and the plant material was kept in ? X MS liquid without sucrose in the dark for all subsequent steps. Cultures were shaken at 140 rpm at 22 C for 24 h and then treated with ? X MS without glucose or ½ X MS supplemented with BR (100 nM), glucose (3%), or glucose (3%) + BR (100 nM) for 3 h. Seedlings were harvested after 3h and preceded for RNA isolation and microarray analysis.
