Response of aspen cell cultures to combinatorial feeding of methyl jasmonate and AOPP.

ABSTRACT: To better understand the role of phenylpropanoid pathway perturbation in plant metabolism, Populus tremuloides cell cultures previously established from leaf mesophyll tissue were fed with methyl jasmonate, alpha-aminooxy-beta-phenylpropionic acid (AOPP), or both approximately 5 days after transfer to fresh medium. Methyl jasmonate is an elicitor that activates a suite of defense responses including phenylpropanoid metabolism. In contrast, AOPP acts as an inhibitor of phenylalanine ammonia lyase (PAL). Samples were harvested 48 hrs after initiation of the experiment. Total RNA was extracted and gene expression measured using Affymetrix poplar genome microarrays.

Response of aspen cell cultures fed piperonylic acid to methyl jasmonate.

Project description:To better understand the role of phenylpropanoid pathway perturbation in plant metabolism, Populus tremuloides cell cultures previously established from leaf mesophyll tissue were fed with piperonylic acid (PIP) alone, or in combination with methyl jasmonate (MJ_PIP) approximately 5 days after transfer to fresh medium. Methyl jasmonate is an elicitor that activates a suite of defense responses including phenylpropanoid metabolism, while PIP acts as an inhibitor of cinnamate-4-hydroxylase (C4H). Sample tissues were contemporary with those used to generate Series GSE16773. Samples were harvested 48 hrs after initiation of the experiment. Total RNA was extracted and gene expression measured using Affymetrix poplar genome microarrays.

Grapevine cell cultures transcriptomic response to methyl jasmonate and cyclodextrin elicitors

Project description:The specificity and synergisms of methyl jasmonate and cyclodextrin elicitor effects in grapevine were analysed at the transcrptomic level. To this end, 12-14 day old cell cultures established from Vitis vinifera L. cv Monastrell calli were elicited with 50 mM cyclodextrin (CD), 100 µM methyl jasmonate (MJ) or the combination of both elicitros (MJ+CD). The experiment was carried out in triplicate and untreated cell cultures were followed in parallel as a control. Cells of each culture were isolated just prior and 24h after the treatment to obtain RNA. GrapeGen GeneChip microarray hybridization was performed from each sample. ****[PLEXdb(http://www.plexdb.org) has submitted this series at GEO on behalf of the original contributor, Pablo Carbonell-Bejerano.

Transcription profiling of grapevine cell culture treated with methyly jasmonate, salicylic acids and ethanol controls

Project description:Calli generated from grape berries were used to establish a cell suspension in Gamborgs B5 liquid medium with minimal organics supplemented with 30 gL-1 sucrose, 0.25 gL-1 casein hydrolysate, 0.93 ?M kinetin and 0.54 ?M naphthaleneacetic acid (NAA) and incubated in darkness at 26°C. <br>The cells were cultured in 250 mL flasks (50 mL of cell suspension in each) incubated in darkness on an orbital shaker at 100 rpm. The cell suspensions were sub-cultured every 2 weeks using an initial packed cell volume (PCV) of 15%. For the evaluation of the effect of elicitor addition on the changes in gene expression, 100 mL flasks containing 20 mL of the above cell suspension were used. Each treatment was conducted in triplicate.<br><br>In a set of preliminary experiments studying the effect of elicitors on the volatiles produced by the cell suspensions, the compounds were added during the exponential growth phase when the PCV was approximately 50%. After 72h incubation in darkness after elicitor addiction, cells were harvested. The elicitors screened for their ability to induce volatile compound production were: 500 µM methyl jasmonate (MeJA); 500 uM MeJA + 500 µM salicylic acid (SA); 500 µM jasmonic acid (JA). Controls were conducted by adding the same volume of the solvent used to dissolve each elicitor to the cultures. For the jasmonate and SA experiments the solvent was ethanol.<br>

Effect of Methyl jasmonate of the Poplar root transcriptome

Project description:Illumina HiSeq technology was used to generate mRNA profiles from Populus tremula x alba INRA 717-1B4 roots treated with Methyl jasmonate. Samples were harvested after two weeks either from untreated control roots or from Methyl jasmonate treated roots. Paired-end (2X100bp) reads were generated and aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) using CLC Genomics Workbench 6. mRNA profiles from Populus tremula x alba INRA 717-1B4 roots treated with Methyl jasmonate as well as from control roots were generated by paired-end (2X100bp) Illumina HiSeq sequencing. Four samples were sequenced per lane, two biological replicates per treatment.
