Project description:Small RNAs (sRNAs) play important roles in plants encountering stress environments. However, limited research has been conducted on the sRNAs involved in plant wound responses. To identify potential roles for the wounding-related sRNAs, sRNA deep sequencing was used. After leaves were wounded for 0.5 hour, total RNAs from unwounded and wounded leaves were isolated for sRNA library construction. The Illumina platform was used to sequence sRNA libraries. About 12 million sequence reads were obtained for each sample.

Project description:To establish the role of the Glutamate Receptor-like gene in Marchantia polymorpha, MpGLR , in wound-induced gene expression changes, we compared the transcriptomes of plants that are wild type for MpGLR to the transcriptomes of Mpglr-7, a deletion mutant in MpGLR, analyzing samples from intact plants and from wounded plants, both from damaged tissues and from systemic undamaged tissues of wounded plants.

Project description:Plant microRNAs (miRNAs) have emerged as important regulators in developmental processes and stress responses in plants. To identify the wound-responsive miRNAs in the leaves of sweet potato, small RNA deep sequencing was conducted on unwounded and wounded leaves (30 min). Total RNAs were isolated for library construction and analyzed by RNA-sequencing via Illumina Genome Analyzer IIx platform. About 16 million total reads were obtained for each sample.

Project description:LapA encodes an acidic leucine aminopeptidase that is wound-inducible and found only in tomato (Solanum lycopersicum) and a small subset of the Solanaceae. LapA is expressed in developing flowers, fruit and in foliage after wounding, insect feeding (Manduca sexta), Pseudomonas syringae pv. tomato infection, salinity, and water-deficit stress. Using Agrobacterium tumefaciens, UC82b plants were transformed with a chimeric gene containing the CaMV 35S promoter and LapA cDNA in the sense orientation. Kanamycin-resistant plants were screened by RNA and protein blots to identify plants that did not accumulate and LAP-A protein upon wounding; these plants were designated LapA-silenced (LapA-SI) lines. The LapA-SI plants have an impaired wound response and do not accumulate wound response transcripts (proteinase inhibitors and polyphenol oxidase) to wild-type levels. LAP-A is the first aminopeptidase to be shown to have a regulatory role in plants. LapA-SI and UC82b plants were germinated on filter paper for 7 days before being planted in soil. Plants were grown in a growth chamber, (16 hour days at 28°C, 8 hour nights at 24°C, 50% humidity) for three weeks. Plants were wounded by crushing each leaflet on each of two lower leaves with pliers. Wounded leaves were collected at 0, 1 and 8 hr (local wounded tissue). Two upper, unwounded leaves were collected from the same plants at the same times (systemically wounded tissue). Five to seven plants were pooled for each time point. The experiment was repeated three times. RNA was extracted using a hot phenol/LiCl protocol and purified and DNase treated using the SV Total RNA Isolation Kit from Promega.

Project description:Dendritic epidermal T cells (DETC) reside in murine skin and participate in homeostasis and wound repair. Upon wounding, DETC become activated through the recognition of an unidentified ligand expressed by keratinocytes proximal to sites of injury. Such DETC activation is mediated through a monoclonal T cell receptor (TCR). Using a soluble form of this monoclonal TCR, we have shown that keratinocytes upregulate DETC TCR ligands in wounded tissue within 2 hours following wounding. Down-modulation of the ligand is seen 3 hours following wounding, and no expression is evident in non-wounded skin. In vitro studies on cell lines which express this unknown ligand indicate that antigen recognition by the DETC TCR is dependent upon N-linked glycosylation of the ligand. Given the glycosylation sensitivity of the ligand and the restricted expression following wounding, we are interested in pursuing microarray analysis to identify genes that are modulated in keratinocytes in response to wounding. Keratinocytes represent 90% of the cells in the epidermis (DETC and Langerhan’s cells make up the remaining 10%). As such, we propose to isolate RNA from whole epidermis under either wounded or resting conditions. In addition to comparing RNA from wounded and non-wounded epidermis, we would like to compare RNA from tissue that has been wounded for different times. Initially, we would like to analyze 4 sampes (non-wounded epidermis, and epidermal cells isolated 30 minutes, 2 hours, and 4 hours following wounding). These time points would correlate to a period prior to cell surface expression of ligand (30 minutes), during cell surface expression (2 hours), and following down regulation of cell surface expression (4 hours). In addition to providing possible identification of the unknown DETC TCR ligand, such analysis would provide novel information about early responses by keratinocytes in response to physical wounding in vivo. We propose to isolate RNA from whole epidermis under either wounded or resting conditions. In addition to comparing RNA from wounded and non-wounded epidermis, we would like to compare RNA from tissues that has been wounded for different times.

Project description:In a previous study, we found that wound-induced transcriptional expression is strongly correlated with an increase of the level of acetylation of the N-tails of histone 3. To investigate if the increase in histone acetylation is a prerequisite for the induction of wound-induced gene expression, we performed transcriptional profiling of wounded roots with and without treatment with γ-butyrolactone (MB3), a chemical inhibitor of GNAT-MYST family of histone acetyltransferase .

Project description:The plant hormone jasmonic acid (JA) has been known as a signal molecule that is induced by various stresses and mediates plant defense responses. Rice O. sativa inductively produces variety of defensive compounds upon abiotic and biotic stress conditions, such as wounding and insect attack. We identified wound-inducible genes by comparison with transcriptomes between wounded and untreated wild-type rice leaves.

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).
