Project description:Gene expression response of Populus cell cultures subjected to methyl jasmonate feeding was analyzed using the Affymetrix poplar genome microarrays. Experiment Overall Design: Populus tremuloides suspension cells were treated with methyl jasmonate (MJ) in DMSO or with DMSO alone (C). Cells were harvested after 48 hours. Two biological replicates were obtained for each condition.

Project description:This SuperSeries is composed of the following subset Series:; GSE16773: Gene expression response of Populus tremuloides cell suspension cultures to methyl jasmonate feeding; GSE16783: Wound-induced gene expression changes in Populus: 1 week; GSE16785: Wound-induced gene expression changes in Populus: 90 hours; GSE14893: Comparative transcriptomics analysis of Populus leaves under nitrogen limitation: clone 3200; GSE14515: Comparative transcriptomics analysis of Populus leaves under nitrogen limitation: clone 1979 Experiment Overall Design: Refer to individual Series
Project description:The expression of stress-related genes induced by feeding of chestnut moth larvae (Conistra vaccinii L.) was studied with Vitreoscilla hemoglobin-expressing (VHb) and non-transgenic hybrid aspen lines (Populus tremula x P. tremuloides). Besides the herbivore-injured leaves (L1), cDNA microarray analyses were conducted using uninjured leaves of hybrid aspen lines positioned above (A) and below (B) the herbivory exposed leaves.
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.
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.
Project description:Aim of the project: Genome wide gene expression profiles across the cambial zone are analyzed in 35um resolution from wild type hybrid aspen (Populus tremula x tremuloides) and two independent LMX5::AtIPT7 over expressor transgenic Populus tree lines.
Project description:The expression of stress-related genes induced by feeding of chestnut moth larvae (Conistra vaccinii L.) was studied with Vitreoscilla hemoglobin-expressing (VHb) and non-transgenic hybrid aspen lines (Populus tremula x P. tremuloides). Besides the herbivore-injured leaves (L1), cDNA microarray analyses were conducted using uninjured leaves of hybrid aspen lines positioned above (A) and below (B) the herbivory exposed leaves. Two-condition experiment, control vs. herbivory exposure. Two hybrid aspen lines: non-transgenic V617 and VHb expressing V617 /45. Of each plant, three leaf types were analysed: the injured/uninjured leaf (L1) and nonorthostichous leaf positioned above (A) and below (B). Biological replicates: 3. On each array, two samples representing L1, A or B leaf type of control and herbivory treatment of either V617 or V617/45 line. line V617: wt_A_rep1-3, wt_B_rep1-3, wt_L1_rep1-3 line V617/45: VHb_A_rep1-3, VHb_B_rep1-3, VHb_L1_rep1-3 leaf type A: wt_A_rep1-3, VHb_A_rep1-3 leaf type B: wt_B_rep1-3, VHb_B_rep1-4 leaf type L1: wt_L1_rep1-3, VHb_L1_rep1-5
