Salicylic acid-induced gene expression in wild-type Col-0 and mutant ube4 Arabidopsis thaliana plants

ABSTRACT: Activation of plant immunity is associated with dramatic transcriptome reprogramming to prioritise immune responses over normal cellular functions. Changes in gene expression are coordinated by the immune hormone salicylic acid (SA). Here we investigated the involvement of the E4 ubiquitin ligase UBE4/MUSE3 in SA-induced transcriptional reprogramming. We show that loss of UBE4 function results in amplified expression of SA-induced, NPR1-dependent gene expression. Twelve-day old Arabidopsis thaliana seedlings of wild-type Col-0, mutant ube4 (SAIL_713_A12) and mutant npr1-1 genotypes were grown on MS media supplemented with 1X Gamborg vitamins in an environmental chamber with 16/8 hour day/night light regime (120 mol m-2 s-1 light intensity) and 22 degrees Celcius. Seedlings were then transferred to 6-well plates and immersed in 10 ml of 0.5 mM SA or water. After 12 hours seedlings were harvested and for each treatment ~50 seedlings were pooled together into a single biological repeat. In total two independent biological repeats were collected. After harvesting seedlings were briefly dried on tissue and immediately frozen in liquid nitrogen until further analysis.

Salicylic acid-induced gene expression in wild-type Col-0 and mutant upl1, upl5, and npr1-1 Arabidopsis thaliana plants

Project description:The plant immune hormone salicylic acid (SA) modulates transcriptional reprogramming via controlling the master transcriptional coactivator, NPR1. Here we examined the role of HECT-type ubiquitin ligases, UPL1 and UPL5, in SA/NPR1-dependent transcriptional control. We showed that UPL1 and UPL5 are essential regulators of SA-responsive genes, and regulate SA-induced transcriptional reprogramming in a NPR1-dependent manner. Four-week old Arabidopsis thaliana plants of wild-type Col-0, mutant upl1, mutant upl5, and mutant npr1-1 genotypes were germinated on soil in 100% relative humidity. Plants were continuously grown in an environmental chamber with 16/8 hour day/night light regime (120 mol m-2 s-1 light intensity), 21/18 degrees celcius day/night cycle and 65% relative humidity. 4-week-old plants were sprayed with water or 0.5 mM SA until all leaves were thoroughly covered with fine droplets, samples were collected after 24 hours treatment. In total two independent biological repeats were collected.

Salicylic acid-induced gene expression in wild-type Col-0 and mutant upl3-4 Arabidopsis thaliana plants.

Project description:Activation of plant immunity is associated with dramatic transcriptome reprogramming to prioritise immune responses over normal cellular functions. Changes in gene expression are coordinated by the immune hormone salicylic acid (SA). Here we investigated the involvement of the HECT-type ligase Ubiquitin Protein Ligase 3 (UPL3) in SA-induced transcriptional reprogramming. We show that UPL3 acts as an amplifier of SA-induced changes in gene expression. Four-week old Arabidopsis thaliana plants of wild-type Col-0 and mutant upl3-4 genotypes were germinated on soil in 100% relative humidity. After 12 days plants were transplanted to larger pots (six plants per pot) and grown for an additional 3 weeks before experimental treatment. Plants were continuously grown in an environmental chamber with 16/8 hour day/night light regime (120 mol m-2 s-1 light intensity), 21/18 degrees celcius day/night cycle and 65% relative humidity. Plants were then sprayed with water or 0.5 mM SA until all leaves were thoroughly covered with fine droplets. After 24 hours leaf tissue was harvested from 6 plants per treatment and pooled together into a single biological repeat. In total two or three independent biological repeats were collected. After harvesting leaf tissue was immediately frozen in liquid nitrogen until further analysis.

1-aminocyclopropane-1-carboxylic acid (ACC)-induced gene expression in wild-type Col-0, mutant upl3 upl4, mutant ein3-1, and mutant upl3 upl4 ein3-1 Arabidopsis thaliana plants

Project description:The plant hormone ethylene is involved in plant developmental, stress and environmental signalling. The ethylene signalling pathway is modulated by the master transcription factor EIN3. Here we examined the involvement of proteasome-associated UPL3 and UPL4 ubiquitin ligases in ethylene-responsive gene expression. We reveal that in absence of functional UPL3 and UPL4, plants show constitutive and enhanced activation or repression of ethylene-responsive genes in an EIN3-dependent manner. Ten-day old Arabidopsis thaliana seedlings of wild-type Col-0, mutant upl3 upl4, mutant ein3-1, and mutant upl3 upl4 ein3-1 were grown on MS media in an environmental chamber with 16/8 hour day/night light regime (120 mol m-2 s-1 light intensity) and 22 degrees Celsius. Seedlings were then transferred to 6-well plates and floated on the surface of water or 50 uM 1-aminocyclopropane-1-carboxylic acid (ACC). After 3 hours seedlings were harvested and for each treatment ~50 seedlings were pooled together into a single biological repeat. In total three independent biological repeats were collected. After harvesting seedlings were briefly dried on tissue and immediately frozen in liquid nitrogen until further analysis.

Transcription profiling of Arabidopsis wild type, AtVdac1 knock-outs, p26 knock-outs and AtVdac1-p26 double kock-outs in response to growth in medium with salicylic acid

Project description:Functions of AtVDAC1 and its partner p26 in Arabidopsis thaliana. We previously showed that knock-out mutants impaired in AtVdac1 and p26 (AtVdac1 protein partner) are hypersensitive to salicylic acid: the root growth is more inhibited in response to 30 uM salicylic acid (SA) compared to the wild type. We want to know now which genes are up- or down-regulated in the mutants in control and SA conditions.<br> We want to compare the RNAm contents in the wild type, vdac1 and p26 mutants and, vdac1-p26 double mutant. One-week old plantlets were transferred for 2 hours on a fresh medium containing either 0 or 30uM salicylic acid.<br> Arabidopsis lines (WT, vdac1.1, p26.1, vdac1.1-p26.1) were grown in vertical position on ABIS medium (Lanquar et al., 2006). One week-old seedlings were transferred on a fresh ABIS medium containing either 0 or 30 uM salicylic acid. After 2 hours, the all seedlings were harvested. Three replicates were done; total RNAs from these 3 experiments were mixed together for the transcriptomic analysis.

Analysis of the molecular dialogue between gray mold (Botrytis cinerea) and grapevine (Vitis vinifera) reveals a clear shift in defense mechanisms during berry ripening

Project description:Mature grapevine berries at the harvesting stage (MB) are very susceptible to the gray mold fungus Botrytis cinerea while veraison berries (VB) are not. We conducted simultaneous microscopic and transcriptomic analyses of the pathogen and the host to investigate the infectious process developed by B. cinerea on MB versus VB, and the plant defense mechanisms deployed to stop the fungus development. On the pathogen side, our genome-wide transcriptomic data revealed that B. cinerea genes up-regulated during infection of MB are enriched in functional categories related to necrotrophy such as degradation of plant cell wall, proteolysis, membrane transport, reactive oxygen species generation and detoxification. Quantitative-PCR on a set of representative genes related to virulence and microscopic observations further demonstrated that the infection is also initiated on VB but stops at the penetration stage. On the plant side, genome-wide transcriptomic analysis and metabolic data revealed a defense pathways switch during berry ripening. In response to B. cinerea infection, VB activated a burst of reactive oxygen species (ROS), the salicylate (SA)-dependent defense pathway, the synthesis of the resveratrol phytoalexin and cell-wall strengthening. In opposite, infected MB activated the jasmonate (JA)-dependent pathway which does not stop the fungal necrotrophic process. Grapevine berries at veraison (VB) and harvesting stages (MB) were inoculated with Botrytis cinerea B05-10 and samples were taken at 24h and 48h post-inoculation. An additional uninfected control sample taken at 0h post-inoculation was included in the experimental design. 3 replicates per sample were performed. The total-RNA samples were labeled and used for hybridization on NimbleGen 12plex Vitis vinifera gene expression array.

Transcription profiling of WT and dsr1 Arabidopsis seedlings treated with salicylic acid

Project description:Reactive oxygen species such as hydrogen peroxide (H2O2) are important in biotic and abiotic stress responses in plants, but their source is often unclear. We have identified an Arabidopsis mutant that shows loss of stress responsive GSTF8 gene expression in response to the plant defence signal salicylic acid (SA) . The mutant showed increased susceptibility to both fungal and bacterial pathogens. The dsr1 mutation was mapped to mitochondrial succinate dehydrogenase (SDH1-1) and dsr1 had reduced SDH activity and a lowered mitochondrial H2O2 production. To better understand the loss of SA-response in dsr1, we performed ATH1 microarray analysis in WT and dsr1 10 hours after a 1 mM SA treatment, a point at which we observed maximal SA-induced GSTF8 promoter activity. 4 day old WT (a Columbia line containing a -800GSTF8::LUC reporter) and dsr1 seedlings (a mutant Columbia line containing a -800GSTF8::LUC) reporterwere treated with water (mock) or 1 mM SA for 40 min. Ten hours after treatment, samples were collected.
