Oxidative burst causes loss of tapetal Ubisch body and male sterility in rice

Project description:We identified the nup1 mutant rice that exhibited specific male sterility due to the absence of Ubisch body formation and pollen grain production. We cloned the causal gene and demonstrated that NUP1, a class III peroxidase predominantly expressed in the anther wall, mediated ROS scavenging. The loss-of-function of NUP1 resulted in ROS burst in anthers, which disrupted the oxidation-reduction process and carbohydrate and lipid metabolisms, and thereby led to loss of tapetal Ubisch bodies and ultimately resulted in male sterility in rice. Our study expands the understanding of the molecular mechanisms by which ROS homeostasis regulates cell metabolism, tapetal Ubisch body formation and male fertility in plants.

Staphylococcus aureus stimulates neutrophil itaconate production that suppresses the oxidative burst

Project description:Neutrophils are critical in the host defense against Staphylococcus aureus, a major human pathogen. However, even in the setting of a robust neutrophil response, S. aureus can cause persistent infection. Here we demonstrate that S. aureus impairs neutrophil function by triggering the production of the anti-inflammatory metabolite, itaconate. The enzyme that synthesizes itaconate, Irg1, is selectively expressed in neutrophils during S. aureus pneumonia. Itaconate inhibits neutrophil glycolysis and oxidative burst, which impairs survival and bacterial killing. In a murine pneumonia model, neutrophil Irg1 expression protects critical lung cell populations from oxidative stress but compromises bacterial clearance. S. aureus is thus able to evade innate immune clearance by targeting neutrophil metabolism and inducing the production of the antiinflammatory metabolite itaconate.

Candida glabrata oxidative stress

Project description:Investigating the oxidative stress response: Candida glabrata strains were stressed with hydrogen peroxide and menadione (causing oxygen radicals) to induce the oxidative stress regulon, which is thought to be upregulated during the oxidative burst inside of phagocytic cells.

Genomic encoding of transcriptional burst kinetics

Project description:We sequenced allele-resolution single-cell transcriptomes from mouse primary fibroblasts and embryonic stem cells with the overall aim to infer transcriptional kinetics for each gene and allele. Inferred transcriptional burst kinetics revealed the genomic encoding of transcriptional burst frequencies and sizes within the genome. Core promoter elements were found to specify burst sizes, whereas burst frequencies were regulated by enhancers. In particular burst frequencies were found to account for cell-type differences in gene expression levels and were also mostly correlating with absolute expression levels in cells. Importantly, the patterns identified were not detectable at the level of mean expression demonstrating the need to investigate transcriptional dynamics at the level of burst kinetics.

Comprehensive analysis of genic male sterility-related genes in Brassica rapa using Brassica rapa 300k microarray v2.0

Project description:To identify genes associated with genic male sterility (GMS) that could be useful for hybrid breeding in Chinese cabbage (Brassica rapa ssp. pekinensis), floral bud transcriptome analysis was carried out using a B. rapa microarray with 300,000 probes (Br300K). Among 47,548 clones deposited on a Br300K microarray with seven probes of 60 nt length within the 3' 150 bp region, a total of 10,622 genes were differentially expressed between fertile and sterile floral buds; 4,774 and 5,848 genes were up-regulated over 2-fold in fertile and sterile buds, respectively. However, the expression of 1,413 and 199 genes showed fertile and sterile bud-specific features, respectively. Genes expressed specifically in fertile buds, possibly GMS-related genes, included homologs of several Arabidopsis male sterility-related genes, genes associated with the cell wall and synthesis of its surface proteins, pollen wall and coat components, signaling components, and nutrient supplies. However, most early genes for pollen development, genes for primexine and callose formation, and genes for pollen maturation and anther dehiscence showed no difference in expression between fertile and sterile buds. Some of the known genes associated with Arabidopsis pollen development showed similar expression patterns to those seen in this study, while others did not. BrbHLH89 and BrMYP99 are putative GMS genes. Additionally, 17 novel genes identified only in B. rapa were specifically and highly expressed only in fertile buds, implying the possible involvement in male fertility. All data suggest that Chinese cabbage GMS might be controlled by genes acting in post-meiotic tapetal development that are different from those known to be associated with Arabidopsis male sterility. A total of 14 chips were used for the microarray experiment. Experiments were performed with two biological replicates.

Respiratory burst oxidase homologues D and F in catalase2 deficient plants

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. 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.
