Mitochondrial complex II (succinate dehydrogenase [SDH]) plays roles both in the tricarboxylic acid cycle and the respiratory electron transport chain. In Arabidopsis (Arabidopsis thaliana), its flavoprotein subunit is encoded by two nuclear genes, SDH1-1 and SDH1-2. Here, we characterize heterozygous SDH1-1/sdh1-1 mutant plants displaying a 30% reduction in SDH activity as well as partially silenced plants obtained by RNA interference. We found that these plants displayed significantly higher C ...[more]

Acclimation of photosynthesis to changes in the environment results decreases oxidative stress in Arabidopsis thaliana

Project description:Dynamic acclimation of photosynthesis plays an important role in increasing plant fitness under variable light environments. Acclimation is mediated by a glucose-6-phosphate/phosphate translocator, GPT2. This study examined whether plants lacking GPT2, which are defective in acclimation to increases in light, are more susceptible to oxidative stress. To understand this, we used the model plant of Arabidopsis thaliana (accession Wassilewskija-4 (Ws-4)) and compared this to mutants lacking GPT2. Plants were grown at low light (100 μmol m−2 s−1) for 7 weeks. For acclimation experiments, a set of plant from low light was transferred to 400 μmol m−2 s−1 for 7 days. Microarray analysis showed that gpt2 plants showed a greater induction of stress related genes relative to WT.

Arabidopsis Col-0 and cerk1 treated with chitosan or water

Project description:Microbe-associated molecular pattern (MAMP)-triggered immunity (MTI) is the first layer of molecular defense encountered by pathogens when they attempt to infect plants. MTI is dependent on cell surface pattern-recognition receptors (PRR) which act upstream of mitogen-activated protein kinase (MAPK) pathways. Genetic screening and mutant knock-out lines have largely contributed to our knowledge of MTI. However, genetic screening is confined to phenotype-causing mutations and scarcely enables the discovery of redundantly-acting proteins. We sought to discover protein components that contribute in MTI, using a phenotype-independent approach to discern nucleus-localized proteins after MTI induction. We report on the nuclear proteome of Columbia-0 (Col-0) and chitin elicitor receptor kinase 1 (cerk1) mutant plants 15 min after MTI induction. Our approach revealed that MAMP-treated cerk1 plants had many proteins in common with Col-0-treated plants following chitosan treatment. cerk1 plants also manifested several unique proteins that were absent from Col-0 plants when elicited with chitosan indicating that they also perceive chitosan. Detailed analysis of the identified proteins revealed a nuclear accumulation of transcriptional regulators and transcription factors, DNA-modifying enzymes, RNA-binding proteins and ribosomal proteins. No novel MAPKs were found although Receptor for activated C kinase 1, a scaffold protein involved in defense, and a nucleotide binding leucine-rich repeat protein, implicated in resistance to Leptosphaeria maculans, were discovered in the nucleus of chitosan-treated plants and absent from water-treated control plants.

Exogenous slaicylic acid (SA) treatment of Arabidopsis thaliana Col-0

Project description:0.5 mM SA plus 0.02% Silwet or 0.02% Silwet (control) was sprayed on leaves of 3.5 week old Arabidopsis plants. Samples were harvested at 0 (prior to treatment) , 3, 6, 12, and 24 hours post treatment. A subset of these samples were processed. Arabidopsis plants grown in parallel under standardized conditions were treated with SA + Silwet or Silwet alone (control). Only mature leaves of the same developmental age were harvested using leaves from 2-4 plants, totalling ~0.2 grams per sample. Plants were not resampled. In our hands, experimental replicates are highly reproducible. This was an exploratory experiment to look for candidate genes impacted by exogenous SA treatment. We were only able to process a subset of samples and chose to process key time points, sacrificing replicates at each time point.

Arabidopsis thaliana gene expression changes upon treatment with green peach aphid saliva

Project description:Myzus persicae (green peach aphid) feeding on Arabidopsis thaliana induces a defense response, quantified as reduced aphid progeny production, in infested leaves but not in other parts of the plant. Similarly, infiltration of aphid saliva into Arabidopsis leaves causes only a local increase in aphid resistance. Further characterization of the defense-eliciting salivary components indicates that Arabidopsis recognizes a proteinaceous elicitor with a size between 3 to 10 kD. Genetic analysis using well-characterized Arabidopsis mutant shows that saliva-induced resistance against M. persicae is independent of the known defense signaling pathways involving salicylic acid, jasmonate, and ethylene. Among 78 Arabidopsis genes that were induced by aphid saliva infiltration, 52 had been identified previously as aphid-induced, but few are responsive to the well-known plant defense signaling molecules salicylic acid and jasmonate. Quantitative PCR analysis confirms expression of saliva-induced genes. In particular, expression of a set of O-methyltransferases, which may be involved in the synthesis of aphid-repellent glucosinolates, was significantly up-regulated by both M. persicae feeding and treatment with aphid saliva. However, this did not correlate with increased production of 4-methoxyindol-3-ylmethylglucosinolate, suggesting that aphid salivary components trigger an Arabidopsis defense response that is independent of this aphid-deterrent glucosinolate. Experiment Overall Design: 3 biological replicates (control and treatment). Total number of samples: 6.

Transcription factor ATAF1 integrates carbon starvation responses with trehalose metabolism

Project description:Global transcriptome patterns were obtained from ATAF1-IOE seedlings at 1 h, 2 h and 5 h after estradiol induction or mock treatment, and from mature ATAF1-IOE leaves at 5 h after estradiol induction or mock treatment. To identify genes rapidly responding to elevated ATAF1 expression estradiol induction experiments were performed on ATAF1-IOE seedlings after 1 h, 2 h and 5 h of ATAF1 induction. In addition, expression profiles were obtained from mature leaves after 5 h of ATAF1 induction.

Expression profiling of uninfected and Golovinomyces orontii infected Arabidopsis thaliana wild type Col-0 and del1-1 mutant

Project description:In plants, the activation of immunity is often inversely correlated with growth. Mechanisms that plant growth in the context of pathogen challenge and immunity are unclear. Investigating Arabidopsis infection with the powdery mildew fungus, we find that the Arabidopsis atypical E2F DEL1, a transcriptional repressor known to promote cell proliferation, represses accumulation of the hormone salicylic acid (SA), an established regulator of plant immunity. DEL1 deficient plants are more resistant to pathogens and slightly smaller than wild type. The resistance and size phenotypes of DEL1 deficient plants are due to the induction of SA and activation of immunity in the absence of pathogen challenge. Moreover, Enhanced Disease Susceptibility 5 (EDS5), a SA transporter required for elevated SA and immunity, is a direct repressed target of DEL1. Together, these findings indicate that DEL1 control of SA levels contributes to regulating the balance between growth and immunity in developing leaves. Mature, fully expanded leaves of 41/2-week-old Col-0 and del1-1 plants were harvested at 5 days after G. orontii infection and from uninfected control plants for RNA extraction and hybridization on Affymetrix microarrays.

Transcript profiling of the wild type Arabidopsis grown under different photoperiods

Project description:Arabidopsis rosette leaves were harvested from plants grown under different photoperiods under 100 M-5mol photons m-2 s-1 at 20 M-0C. In the first experiment plants grown under short day conditions 8L/16D (8 h light / 16 h dark) for 4 weeks were compared with plants grown under long day (16L/8D) for 3 weeks. In the second experiment plants grown under 12L/12D for 2 weeks were compared with plants grown first 2 weeks under 12L/12D and then two days under short day (8L/16D) conditions.
