Respiratory burst oxidase homologues D and F in catalase2 deficient plants

ABSTRACT: Hydrogen peroxide (H2O2) can act as a signaling molecule that influences various aspects of plant growth and development, including stress signaling and cell death. Catalase deficient plants are pioneering systems which accumulate hydrogen peroxide (H2O2) from peroxisomal origin during photorespiratory challenges. Respiratory burst oxidase homologues D and F are known to participate in intracellular oxidative stress response launched in cat2 mutants (Chaouch et al., 2012). We studied the compared the transcriptional response of cat2 rbohD and cat2 rbohF double mutants versus the cat2 background to further adress their role during photorespiratory stress. After 3 weeks of growth, leaf tissue from the three different genotypes was harvested in triplicate.

In the last decade, microarray studies have delivered extensive inventories of transcriptome-wide changes in messenger RNA levels provoked by various types of oxidative stress in Arabidopsis (Arabidopsis thaliana). Previous cross-study comparisons indicated how different types of reactive oxygen species (ROS) and their subcellular accumulation sites are able to reshape the transcriptome in specific manners. However, these analyses often employed simplistic statistical frameworks that are not com ...[more]

Transcriptomic responses of cat2-2 and shr-6 cat2-2 to photorespiratory conditions

Project description:Hydrogen peroxide (H2O2) is a potent signaling molecule influencing various aspects of plant growth and development. Its limited lifetime and specific production sites in the plant cell necessitate the existence of specialized mechanisms that relay H2O2-encoded information. To discover such mechanisms, we focused on peroxisomal H2O2 production triggered by enhanced photorespiration in Arabidopsis mutants lacking catalase activity (cat2-2), and looked for second-site mutations that attenuate the negative effects (Fv'/Fm' decline and lesion formation) of H2O2 build up. A mutation residing in the GRAS family transcriptional regulator SHORT-ROOT (SHR) was found to underlie the increased performance of cat2-2 knock-outs under photorespiratory stress. In contrast to shr, introduction of the scr mutation in cat2-2 background did not improve the photorespiratory performance of plants lacking peroxisomal catalase. The absence of SHR negatively affected the activity of the photorespiratory enzymes glycolate oxidase and catalase, which was accompanied with elevated glycolate content and inability to accumulate glycine under conditions promoting photorespiration. The transcriptome signature of cat2-2 shr-6 double mutants exposed to photorespiratory stress lacked jasmonate-dependent signaling components, otherwise induced in cat2-2. The photorespiratory phenotype of cat2-2 was found to be modulated by exogenous sugars both in the presence and absence of shr. Taken together, these findings highlight a crucial role for SHR in H2O2 signal transduction and stress tolerance. Three-week-old cat2-2 and shr-6/cat2-2 plants were exposed to photorespiratory conditions. Rosettes were sampled in three biological replicates before (T = 0) and after 24 hours (T = 24H) of the treatment. Total RNA was extracted with Spectrum Plant Total RNA Kit (Sigma) and submitted to Arabidopsis ATH1 microarray hybridization.

Arabidopsis GLYCOLATE OXIDASE 1 and 2 display divergent roles under conditions promoting photorespiration

Project description:Hydrogen peroxide (H2O2) can act as a signaling molecule that influences various aspects of plant growth and development, including stress signaling and cell death. To unravel the molecular mechanisms that regulate the response towards an impact of increased H2O2 levels in plant cells, we focused on the photorespiration-dependent peroxisomal H2O2 production in Arabidopsis thaliana mutants lacking CATALASE2 (CAT2) activity (cat2-2) and screened for second-site mutations that attenuate the Fv'/Fm' decrease and lesion formation linked to the cat2-2 phenotype. A mutation in GLYCOLATE OXIDASE 1, encoding one of the two photorespiratory isoforms of glycolate oxidase rescued the cell death phenotype of cat2-2 plants under photorespiration-promoting conditions. Interestingly, introduction of gox2 into the cat2 background did not have the same effect and the double cat2 gox2 mutants were as affected as the parental cat2 mutants under conditions promoting photorespiration. Using a series of physiological, biochemical and metabolomic approaches we investigated the differential photorespiratory response of cat2 mutants underlied by the lack of GOX1 and GOX2. These differences are in line with the non-redundant functions of GOX1 and GOX2 which could be observed under enhanced photorespiration.

SHORT-ROOT Deficiency Alleviates the Cell Death Phenotype of the Arabidopsis catalase2 Mutant under Photorespiration-Promoting Conditions

To unravel the molecular mechanisms that regulate the response towards an impact of increased H2O2 levels in plant cells, we focused on the photorespiration-dependent peroxisomal H2O2 production in Arabidopsis thaliana mutants lacking CATALASE2 (CAT2) activity (cat2-2) and screened for second-site mutations that attenuate the Fv'/Fm' decrease and lesion formation linked to the cat2-2 phenotype. A mutation in the transcriptional regulator SHORT-ROOT (SHR) of the GRAS family rescued the cell death phenotype of cat2-2 plants under photorespiration-promoting conditions in a SCR-independent way, and provoked perturbation of photorespiratory metabolites. SHR deficiency boosted ascorbate levels and prevented the oxidation of the glutathione pool in cat2-2 background upon exposure to photorespiratory stress. These results reveal an unanticipated role for SHR as a regulator of cellular redox homeostasis. Unstressed and stressed samples of 4 genotypes (Col-0, cat2, shr and cat2 shr) in triplicate

Microarray analysis of Arabidopsis Col-0 and catalase 2 mutant define interactions between CO2, daylength and H2O2

Project description:Growth daylength, ambient CO2 level, and intracellular hydrogen peroxide (H2O2) availability all impact plant function by modulating signalling pathways, but interactions between them remain unclear. Using a whole-genome transcriptomics approach, we exploited the conditional photorespiratory nature of the catalase-deficient cat2 mutant to identify gene expression patterns responding to these three factors. Arabidopsis Col-0 and cat2 grown for 5 weeks in high CO2 in short days (SD) were transferred to air in SD or long days (LD), and microarray analysis was performed. Of more than 500 genes differentially expressed in Col-0 between high CO2 and transfer to air in SD, the response of about one-third was attenuated by transfer to air in LD. H2O2-responsive genes in cat2 were highly dependent on daylength. The majority of H2O2-induced genes were more strongly up-regulated after transfer to air in SD than to LD, while a smaller number showed an opposing pattern. Responses of other H2O2-dependent genes indicate redox-modulation of the daylength control of fundamental cell processes. The overall analysis provides evidence that (1) CO2 level modulates stress-associated gene expression; (2) both CO2 and H2O2 interact with daylength and photoreceptor signalling pathways; and (3) cellular signalling pathways may be primed to respond to increased H2O2 in a daylength-determined manner. Two genotypes x five conditions experiment, including Arabidopsis Col0WT and cat2-1 plants grown in soil for 5 weeks in a 8h light/16h dark (short day) regime at high CO2 concentration (3000 ppm CO2) and subsequently transferred to air (400 ppm CO2) in a short day or long day (16h light/8h dark) regime for 2 and 4 days. Three biological replicates were used that consist each of a pool of two leaves from different plants. Each sample was hybridized to one Genechip® Arabidopsis ATH1 Genome Array (Affymetrix).
