Gravitropic stimulation / isotropic light-Characterization of early molecular events of woody stem gravitropism independently of phototropic responses

ABSTRACT: 12plex_poplar_2012-01 - gravitropic stimulation / isotropic light - The experiments were designed to identify genes responding to the gravitropic stimulus in the xylem of poplar stem independently of phototropic responses. - young poplar trees were staked one week before use. For the experiment, the plants were placed in an isotropic light environment and were tited at 35° during 30 min. Control plants were kept straight in the isotropic light device. Xylem samples were collected from the upper and lower face of the stems. 4 biological replicates were made (4 controls and 4 tilted plants). RNA was extracted from each xylem sample. cDNA was synthetized. The discovery of genes whose expression is modulated by tilting was performed by a microarray approach.

rewatering-Global gene expression in young differentiating xylem of poplar in response to a drought ârewatering cycle

Project description:affy_rewatering_poplar - rewatering - Biological question (15 lines max): Xylogenesis is a complex process and is highly influenced by environmental factors. Numerous studies have shown xylem structural acclimation to moderate and long-lasting water deficits. A decrease in cell lumen size and an increase in vessel density are generally observed. Other preliminary experiments in our laboratory focusing on a short and progressive drought-rewatering cycle in poplar show a gradual decrease in fibre size with decreasing water availability and an important rise in vessel number with irrigation recovery. This suggests a reorientation during the early stages of cambial derivatives differentiation towards vessel formation. The aim of this study is to characterize global gene expression in young differentiating xylem of poplar in response to a drought-rewatering cycle. Results should provide a comprehensive genomic basis for the xylem structural modifications observed.-The experimental design consisted in a differential water supply. Experiments were done on tilted trees to induce tension wood formation. Trees were regularly irrigated at full capacitance until July 18, 2007, the beginning of the experiment. Two sets of plants were designed. For each set, irrigation was withheld until July 25, 2007. At this time, one of the two sets (treated-sample) was re-irrigated at full capacitance during 14hrs (WDR) while the other one was maintained under water deficit (WD). Samples were collected after the 14hrs for all trees. Keywords: treated vs untreated comparison 6 arrays - poplar

Isolation of poplar genes involved in xylem vessel differentiation

Project description:Downstream genes of PtVNS genes were explored with inducible expression system using glucocorticoid receptor (GR). Transgenic poplar plants expressing 35S:AtVND7-VP16-GR were treated with dexamethazone (DEX). A number of genes related to the formation of xylem vessels were induced by DEX.

Transcriptome profiling data for secondary vascular tissue regeneration in Populus tomentosa

Project description:Regeneration is a common strategy for plants to repair their damaged body plans after attack from other organisms or physical assaults. Trees with bark girdling on a large scale will grow new bark within one month and this bark regeneration after girdling system has been proven to be an efficient method to study secondary vascular development as well as plant tissue regeneration in vivo. We herein show the molecular features of differentiating xylem cell fate switch process during secondary vascular tissue (SVT) regeneration in Populus. Based on our data, we propose a working model to illustrate the molecular dynamics underlying xylem cell fate switch process during SVT regeneration, which is significant to understand the pattern formation during the SVTs regeneration and also would shed light on the mechanisms of tissue regeneration in plants. Specific regenerated tissues of Populus at different stages were isolated by tangential cryo-sectioning. Total RNA from cryo-sections representing different regenerating tissues was extracted for Affymetrix Poplar Whole Genome Array hybridization. Five samples (two replicates for each sample) were used for gene expression analysis: differentiating xylem (diX, Stage 0), dedifferentiating xylem cells (deX, Stage I), regenerated phloem (rPh, Stage II), differentiating regenerated cambium (diC, Stage II) and regenerated cambium (rC, Stage III). In addition, one pooled genomic DNA sample from cryo-sections of differentiating xylem from two trees was isolated for DNA hybridization to produce a new CDF file that was used to mask out some potentially cross-hybridizing probesets from the standard Affymetrix Poplar Genome Array.

Transcriptome profiling of the basal region of poplar stems during the early gravitropic response

Project description:Young poplar stems show a preponderantly primary growth in the top internodes and differential cambium activity in the basal internodes after inclination with some tension wood formed after 45 min. This study was conducted in order to characterize the early changes in gene expression during early stages of the gravitropic response in the poplar.

Populus metacaspases - The function of two type II metacaspases in woody tissues of Populus trees

Project description:Metacaspases (MCs) are cysteine proteases that are implicated in programmed cell death of plants. AtMC9 (Arabidopsis thaliana Metacaspase9) is a member of the Arabidopsis MC family that controls the rapid autolysis of the xylem vessel elements, but its downstream targets in the xylem remain uncharacterized. PttMC13 and PttMC14 were identified as AtMC9 homologs of hybrid aspen (Populus tremula x tremuloides). A proteomic analysis was conducted in xylem tissues of transgenic hybrid aspen trees which carried either an overexpression or an RNAi construct for PttMC13 and PttMC14. The proteomic analysis revealed modulation of levels of both previously known targets of metacaspases, such as Tudor staphylococcal nuclease, heat shock proteins and 14-3-3 proteins as well as novel targets, such as homologs of the PUTATIVE ASPARTIC PROTEASE 3 (PASPA3) (PASPA) and the cysteine protease RD21 by PttMC13 and PttMC14. We identified here the pathways and processes that are modulated by PttMC13 and PttMC14 in xylem tissues. In particular, the results indicate involvement of PttMC13 and/or PttMC14 in controlling not only xylem cell autolysis but also cell death. This work provides a valuable reference dataset on xylem specific metacaspase functions for future functional and biochemical analyses.

Identification of Developing Xylem-Specific Promoters from Poplar by Using tissue type-Specific Whole Genome Transcriptome Analysis.

Project description:Lignocellulosic feedstock (i.e., wood) is gaining popularity as a source of fermentable sugars for liquid fuel production. To improve the quantity and quality of woody biomass, the developing xylem (DX) cell-specific genetic modification is desired. Bioinformatic analyses followed by the validation of cell type-specific transcriptomes led to the identification of 37 transcripts specifically expressed in DX. After further confirmation of DX-specific expression, we selected four genes (DX5, DX8, DX11 and DX15) to demonstrate the feasibility of our strategy. The promoter regions of selected DX genes were isolated and produced stable transformants of poplar by using transcriptional promoter:β-glucuronidase (GUS) fusion constructs. The GUS expression patterns of DX5 and ANAC073 (orthologous gene of Arabidopsis) revealed that these promoters were active in xylem cells in poplar at early seedling growth, and showed strongest expression in the developing xylem cells in the wood formation/development at later growth stages of poplar. DX specific and strong expression patterns of all the other DX promoters (DX8, DX11 and DX15) tested suggests that these promoters may be useful to control transgene expression in the DX cells of woody plants with the aim of the feedstock improvement.
