Project description:This study examined the transcriptome level attributes of a variety of Populus balsmifera tissues and organs. The tissues include seedlings grown under three light regimes, young leaves, mature leaves, roots, differentiating xylem, female catkins, and male catkins.

Project description:We performed that comprehensive identification of genes responsible for stress tolerance by analyzing the whole-genome expression profiles of poplar (Populus alba × P. glandulosa) leaves exposed to drought and salt stresses. Examination at the molecular level how this tree species responds to drought and salt stresses by regulating the expression of genes involved in signal transduction, transcriptional regulation, and stress responses.

Project description:Generally, salt stress causes both osmotic and ionic stress. To discern the effects of osmotic and ionic specific effects on Burma mangrove transcriptome, we conducted expression profiling in 500 mM NaCl or 1M solbitol treated leaves. This study will lead to a rapid and effective selection of gene that confers high salt tolerance in transgenic plants and to a comprehensive understanding of plant stress response. Keywords: Stress response

Project description:We analyzed the transcriptome in roots, young and mature leaves, nodes and internodes in the reference genotype Nisqually-1 and identified a core set of approximately 10,000 genes expressed in common among vegetative organs. Quantitative contrasts of transcript levels among organs identified expected patterns of expression associated with organ-specific physiological processes, although a surprisingly high number of defense-related genes were preferentially expressed in young leaves and nodes. Application of a novel runs test established an objective criterion for the identification of genomic regions in which adjacent genes were expressed more frequently than expected by chance, suggesting the presence of chromatin domains. Comparisons between P. trichocarpa Nisqually-1 and the P. tremula X P. alba hybrid INRA 717-1B4 revealed similar expression patterns, particularly in stems. Although a comparison to Arabidopsis thaliana revealed similar proportions of expressed genes in leaves and stems, there was very little conservation between rank correlations of expression patterns.

Project description:Rooted plantlets of Populus euphratica were transferred to aerated hydroculture with Long Ashton nutrient solution, grown for 3.5 months at 22°C, 150 µmol m-2 s-1 photosynthetically active radiation with a photoperiod of 16h light. After reaching an average height of 0.83 m, the media was supplemented with 150 mM NaCl (Salt-treated) or maintained under control conditions (control). During the experimental phase, light was continuously supplied to avoid interference of light/dark transitions. <br>Roots and leaves of six plants were harvested separately after 3h, 6h, 12h, and 24h of salt exposure and of controls at the corresponding time points (= 48 plants per experiment). The material of each harvest of 6 plants was pooled, yielding one leaf and one root sample of controls and one leaf and one root sample of salt-treated plants, respectively (=16 samples per experiment).<br>The experiment was performed three times yielding three biological replications (=48 samples in total).<br>After extraction of RNA and cDNA synthesis, each extract was labelled with Cy3 and Cy5, respectively (yielding 96 labelled extracts). Extracts from e.g. 3h-salt-treated leaf exp. 1 (cy3) was hybridized with 3h-control leaf exp.1 (cy5) with microarrays (UHPB-P.euphratica-10K-5; A-MEXP-93)containing unique 7,662 ESTs of P. euphratica from stress-induced cDNA libraries (Brosche et al., Genome Biology 2005, 6:R101). Dye swap was perfomed, thus usually yielding 6 arrays per timepoint and plant tissue (3 biological, 3 technical replicates). In some cases hydridizations were not successfull. Therefore, for roots harvested at timepoints 12h and 24 h only 4 arrays per timepoint were used. For roots harvested after 3h an additional mixed sample of all 3 biological replicates was performed. One leaf array at 6 h was not sucessfull. Therefore, residual labelled extract from salt treated plants of exp1 was hydridized with controls at 6h from exp.2. <br>

Project description:Grapevine rootstock 1616C shoots were sterilized and cultured on Murashige & Skoog (MS) medium containing 2% sucrose (w/v). Plantlets were grown in a growth chamber with a 16-h light/8-h dark cycle for 10 weeks at 25 °C. Plantlets with 4–5 leaves were chosen for use in stress treatments. Experiments were conducted with treatment groups: The control (C, without any chemical treatment), TM (treated with 5 μg mL-1 tunicamycin (TM)) and salt (treated with 400 mM NaCl). Microarray analysis was performed and we investigated transcript profiles in leaves of the salt-tolerant grapevine rootstock 1616C under salt- and ER-stress at 6 and 24 hours

Project description:We conducted micro-array analysis to quantify the global transcriptome variations in leaves through the course of the year allowing for identification of changing developmental signals. We used RNA samples from pre-formed and mature leaves in the upper crown of a sexually mature Populus deltoides tree 2 hours after sunrise.

Project description:We performed that comprehensive identification of genes responsible for stress tolerance by analyzing the whole-genome expression profiles of poplar (Populus alba M-CM-^W P. glandulosa) leaves exposed to drought and salt stresses. Examination at the molecular level how this tree species responds to drought and salt stresses by regulating the expression of genes involved in signal transduction, transcriptional regulation, and stress responses. Genome-wide analysis was conducted in poplar leaves exposed to drought and salt stresses.The plants were acclimated in soil and grown for 6 weeks in controlled conditions in a growth room (16 h light; light intensity, 150 M-NM-<mol m-2sec-1; 24M-BM-0C). Plants with a height of about 15 cm were separately exposed to either drought or salt stress. Up- and down-regulated genes were identified, and their putative functions are discussed.

Project description:Our study identified long term salt stress treatment to induce symptoms similar to developmental senescence. In order to identify possible crosstalk components shared between developmental and salt-triggered senescence. We first obtained the expression profile of Arabidopsis leaves under the condition of salt-induced senescence (4 days) and then compared it with the transcriptome of developmental leaf senescence.
