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

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 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.

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

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 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.

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.
