RNA-seq of Arabidopsis root sieve element markers at 24h of iron deficiency

ABSTRACT: RNA-seq of pPEAR1::dBOX-YFP, pPEAR1-erGFP, and pC2-YFP to characterize the transcriptome associated with progressively more differentiated sieve elements. pPEAR1::dBOX-YFP is the proxy for early / phloem initials. pPEAR1-erGFP is the proxy for transit amplifying protophloem. pC2-YFP is the proxy for differentiation sieve elements. Each marker line was grown for 4 days in standard MS (Murashige & Skoog) media then transferred to iron deficient media (Murashige & Skoog containing ferrozine to chelate any iron present so that it's biounavailable). At 24h after transfer, roots were protoplasted and sorted using Fluorescence Activated Cell Sorting (FACS) to isolate GFP-positive or YFP-positive cells. Then, RNA-seq was performed in the sorted cell populations.

Proteomics of isolated sieve tubes from N.tabacum

Project description:Symplasmicly connected cells called sieve elements form a network of tubes in the phloem of vascular plants. Sieve elements have essential functions as they provide routes for photoassimilate distribution, the exchange of developmental signals, and the coordination of defense responses. Nonetheless, they are the least understood main type of plant cells. They are extremely sensitive, possess a reduced endomembrane system without Golgi apparatus, and lack nuclei and translation machineries, so that transcriptomics and similar techniques cannot be applied. Moreover, the analysis of phloem exudates as a proxy for sieve element composition is marred by methodological problems. We developed a simple protocol for the isolation of sieve elements from leaves and stems of Nicotiana tabacum at sufficient amounts for large-scale proteome analysis. By quantifying the enrichment of individual proteins in purified sieve element relative to bulk phloem preparations, proteins of increased likelyhood to function specifically in sieve elements were identified. To evaluate the validity of this approach, YFP-constructs of genes encoding three of the candidate proteins were expressed in plants. Tagged proteins occurred exclusively in sieve elements. Two of them, a putative cytochrome b561/ferric reductase and a reticulon-like protein, appeared restricted to ER segments that were inaccessible to the luminal ER marker, HDEL-GFP, suggesting a previously unknown differentiation of the endomembrane system in sieve elements. Evidently, our list of promising candidate proteins provides a valuable exploratory tool for sieve element biology.

Transcription profiling of Arabidopdis seedlings - heat, anoxia, and combined heat-anoxia treatments

Project description:Anoxia induces several heat shock proteins and a heat pre-treatment can acclimatize Arabidopsis seedlings to a subsequent anoxic treatment. In this work we analyzed the response of Arabidopsis seedlings to anoxia, heat and a combined heat+anoxia stress. A significant overlapping between the anoxic and heat shock responses has been observed by whole-genome microarray analysis. Experiment Overall Design: We treated Arabidopsis seedling, 4-days old, dark germinated with: Experiment Overall Design: -Control (23Â°C, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: -Heat-treated (38Â°C for 90 minutes, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: -Anoxia-treated (23Â°C, under anoxia for 6h, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: -combined heat+Anoxia-treatment (23Â°C, treated at 38Â°C for 90 min and thereafter under anoxia for 6h, dark, liquid Murashige-Skoog medium containing 30mM sucrose). Experiment Overall Design: Two biological replicates for each condition.

Comparison of IND induced vs. mock treated seedlings: Transcriptome profiling upon induction of the transcription factor IND

Project description:rs10-03_ind - comparison of ind induced vs mock treated seedlings - Identification of miRNAs regulated by IND - Transgenic seeds containing an IND transgene under the control of a dexamethasone inducible promoter were germinated and grown in liquid Murashige/Skoog medium under a 16h light/8h darkness light regime. After seven days of growth, seedlings were either mock-treated or treated with 10 micromolar dexamethasone for 24 hours.

Transcription profiling by array of control and TCP13-SRDX transgenic Arabidopsis plants

Project description:To understand the downstream genes of TCP13, we performed analysis of gene expression using vector control plants and the TCP13 fused repression domain plants (TCP13pro::TCP13SRDX) . TheTCP13pro::TCP13SRDX plants is transgenic plants expressing chimeric repressor (SRDX) fused to TCP13 cDNA using the TCP13 promoter. TCP13 is a drought-inducible gene and play an essential role in leaf morphology. Arabidopsis plants were grown on the Murashige and Skoog (MS) medium (Murashige and Skoog, 1962), supplemented with 3% sucrose and 0.8 % agar (under a 16-h-day (60 ± 10 μmol photons m−2 s−1 light intensity) and 8-h-night regime for 2 weeks.
