Science signaling 20090818 84

Cell-to-cell communication and long-distance signaling play a key role in the response of plants to pests, mechanical wounding, and extreme environmental conditions. Here, we report on a rapid systemic signal in Arabidopsis thaliana that traveled at a rate of 8.4 centimeters per minute and was dependent on the respiratory burst oxidase homolog D (RbohD) gene. Signal propagation was accompanied by the accumulation of reactive oxygen species (ROS) in the extracellular spaces between cells and was ...[more]

Expression data from Arabidopsis leavs 10 min after wounding.

Project description:Rapid responses to biotic and abiotic insults are crucial for plant survival. We examined the very early (10 min) wound transcriptome in order to increase our understanding regarding this critical intial phase of the plant response to stress. Our analysis revealed a rapid induction of stress-related transcripts that was distinct from the long term events which are dominated by jasmonic pathway responses. The transcriptome showed high correlation between the early wound response and other early but not late responses to innate immune interactions and other abiotic stresses. In addition those early responses were correlated with transcriptomes of response to singlet oxygen as displayed in the flu mutant. Singlet oxygen appears to be a signaling intermediate in the plant response to multiple stresses. 6 samples were analysed in total with 2 replicates from each type of treatment; control (unwounded plants), local (woundedd plants) and systemic (unwounded leaves from wounded plants).

Serine protease-mediated wounding identifies localized epidermal wound response genes in Drosophila melanogaster

Project description:We have used trypsin-mediated wounding to amplify the transcriptional response to clean puncture wounding. We studied the transcriptional response of clean puncture wounding and trypsin puncture wounding in relation to unwounded wild-type late-stage embryos. Trypsin puncture wounding generally increases the puncture wounding fold induction relative to unwounded controls.

Proteomic analysis of Caenorhabditis elegans wound model reveals novel molecular players involved in repair

Project description:Now a days, wound healing is becoming a global threat that impact economy of the country severely. Though the steps involved in wound healing are well characterised, direct therapeutics for the accelerated wound healing is comparatively less. This is solely because of the incomplete mechanism of healing and the lack of knowledge on molecular players involved in wound healing. Hence, in the present study, we have investigated the molecular players involved in wound healing process using a versatile model organism Caenorhabditis elegans through proteomic analyses. Especially, we have employed the high through put proteomic analyses tools such as 2-D GE and LCMS/MS analysis to uncover the molecular players involved in wound healing. As a result of LC-MS/MS analysis at 0 and 24 h, a total of 435 proteins were regulated in both unwounded and wounded conditions in which 13 and 10 proteins were significantly differential regulated. Bioinformatics analyses result suggested that molecular players involved in cortical actin cytoskeleton organization, protein phosphatase binding, and proton transporting ATP synthase activity were identified at 0 h; skeletal muscle myosin thick filament assembly, actin filament depolymerization were identified at 24 h.

As a result of 2-D GE analysis, a total of 35 differentially regulated proteins were identified during injury in which 22 and 13 proteins were upregulated and downregulated, respectively. Bioinformatics analyses result suggested that the upregulated proteins have crucial roles in serotonin/ acetyl choline synthesis and calcium signalling, whereas downregulated proteins were majorly involving in ubiquitin mediated proteolysis. Additionally, the mRNA levels of up and downregulated proteins were validated using qPCR analysis. Overall, the study suggested that injury initiates multiple molecular mechanisms to repair the damage.

Expression data from wound skin taken at three time points post wounding

Project description:The full complement of hair follicles is generated during embryogenesis. Normally, no new hair is created after this time. Large full thickness skin excision wounding can result in the generation of new hair in the adult. Placodes can be observed following complete reepithelialization at wound day 14. The events leading to hair neogenesis following wounding remain poorly understood. Late healing events (from wound day 10 to wound day 14) provide a possible window of induction for hair regeneration. We used microarrays to analyse changes in gene expression during late skin healing to provide candidates for factors involved in hair neogenesis following wounding. 6 week old C57Bl/6 mice received large full thickness skin excisions. Healing wound tissue was excised at wound day 10, 12 or 14 and analyzed for gene expression.
