Jasmonates and Histone deacetylase 6 activate Arabidopsis genome-wide histone acetylation and methylation during the early acute stress response

ABSTRACT: To analyze the extent of the overlap between MeJA-induced transcripts and MeJA- induced histone acetylation, the expression profiles of WT untreated (WT), WT+MeJA, axe1-5 untreated and axe1-5+MeJA samples were analysed using the catalog microarray (Agilent design ID:21169). Whole A. thaliana seedlings of axe1-5 mutant and DR5 wild-type lines (Murfett et al 2001) were grown in vitro for 12 days on 1% Murashige and Skoog (MS) medium (Duchefa) supplemented with 1% sucrose, 0.8% phytoagar (Duchefa) and buffered to pH 5.8. Stratification of seeds was performed for 3 days at 4°C in the dark. Seeds were then grown with plates approximately 20° to vertical under 16h light/8h dark cycles for 12 days at 22°C and a light intensity of 100-120 µmol m-2s-1. Twelve-day-old in vitro grown whole seedlings were transferred to 50 µM MeJA or mock plates and sampled after 3 hours for microarray analysis. Expression profiles were analyzed using the catalog microarray (Agilent design ID:21169).

comparison of transcriptomes in mad mutants-Transcriptome analysis of miRNA action deficient mutants

Project description:rs10-04_mad - comparison of transcriptomes in mad mutants - What gene sets are differentially expressed in mad mutants? - Seeds of GFP171.1 (parental line), mad1, mad2, mad3, mad6 and dcl1-12 were sterilized and germinated on Murashige/Skoog medium with 0.9% agar. Plates were stratified at 4C in the dark for 4 days. The plates were then transferred to a growth cabinet at 21C under a 16h light/8h darkness light regime, and the seedlings were harvested 18 days after transfer to the growth cabinet.

affy_ath_2012_05-Arabidopsis Ubiquitin-Like Proteases characterization

Project description:affy_ath_2012_05 - affy_ath_2012_05 - The main objective is to determinate the influence of Ubiquitin-Like Proteases in plant transcriptional modulation. The experiment will also allow us to find what transcriptional cues are particularly affected in the mutants relatively to wild-type.-Seeds were stratified for 3 days at 4ºC in the dark. Afterwards, seeds were surface sterilized, sown onto MS media and grown at 23ºC, with 100 µE light condition, in long days (16h L/8h D). Each MS plate was dived in four, corresponding to a genotype (Col, AB, SIZ1 or SAB), and 10 seeds were sown per genotype. After 10 days, seedlings were collected and frozen in liquid nitrogen. Each replicate was made of ~40 seedlings coming from 4 different MS plates. Frozen plant material was grounded in an eppendorf tube using a mini pestle. RNA was extracted using RNeasy Plant Mini kit (QIAGEN cat.74904), following the manufacturer instructions (QIAGEN, Hilden, Germany). The RNA samples were DNase treated (Recombinant DNase I, Takara Biotechnology, Dalian, China) and subsequently cleaned by column using RNeasy Plant Mini kit (QIAGEN, Hilden, Germany).

Project description:rs04-04_skp2_cul4 - comparison_cul4_as_dark_light - Antisense and mutants of the SKP2 and CUL4 genes are compared to the Wt in order to identify the genes controlled by those SCF proteins. - The seeds have been sown every two days on MS 255 (Duschefa) without adding sugar. These plates stayed 2 days in the dark at 4°C. Then they got a 8 hours light induction (light induction of germination) and then back to the dark for 5 more days.

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
