A dihydrochalcone-specific O-methyltransferase from leaf buds of Populus trichocarpa implicated in bud resin formation

ABSTRACT: We used transcriptomics and differential gene expression analyses of P. trichocarpa and P. balsamifera leaf buds to identify a gene encoding a P. trichocarpa dihydrochalcone-specific O-methyltransferase, which we named PtDOMT1. Detailed enzymatic analyses demonstrated PtDOMT1 to be a highly selective and regiospecific O-methyltransferase which methylates 4 and 4' positions of dihydrochalcones using S-adenosyl-L-methionine as a methyl donor.

RNAseq of transfected protoplasts of Populus trichocarpa

Project description:PtrHSFB3-1 and PtrMYB092 are xylem specific genes in xylem of P. trichocarpa, and their expression levels are down regulated most significantly in tension wood. These two transcription factors were transiently overexpressed in stem differentiating xylem (SDX) of P. trichocarpa , and transcriptomic sequencing was performed to identify the regulatory effects of the two transcription factors on wood formation related genes.

Ozone exposure of Populus deltoides and Populus trichocarpa

Project description:Populus deltoides and Populus trichocarpa were exposed to either ambient air or an acute ozone exposure of 200 ppb for 9 hrs and ozone response was profiled for each genotype by hybridising control against ozone-exposed samples per genotype. Keywords: stress response, genotype comparrison, ozone exposure

Transcriptome analyses of the Laccaria bicolor-Populus trichocarpa mycorrhiza

Project description:Illumina HiSeq2000 technology was used to generate mRNA profiles from the ectomycorrhizal fungi Laccaria bicolor colonizing roots of Populus trichocarpa. Samples were taken after 3 months of contact in order to identify mycorrhiza-regulated transcripts. 100bp reads were generated and aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) reference genome.

Transcriptome analyses of the Laccaria bicolor-Populus trichocarpa mycorrhiza development

Project description:Illumina GAIIx technology was used to generate mRNA profiles from the ectomycorrhizal fungi Laccaria bicolor colonizing roots of Populus trichocarpa. Samples were taken after two, four and 12 weeks of contact in order to identify mycorrhiza-regulated transcripts. 37bp reads were generated and aligned to the Populus trichocarpa (http://www.phytozome.net/poplar.php) and the Laccaria bicolor (http://genome.jgi-psf.org/Lacbi2/Lacbi2.home.html) reference genomes using CLC Genomics Workbench 6.

Comparative physiology and transcriptional networks underlying the heat shock response in Populus trichocarpa, Arabidopsis thaliana and Glycine max [Populus]

Project description:The heat shock response continues to be layered with additional complexity as interactions and cross-talk among heat shock proteins, the reactive oxygen network and hormonal signaling are discovered. However, comparative analyses exploring variation in each of these processes among species remains relatively unexplored. In controlled environment experiments, photosynthetic response curves were conducted from 22 °C to 42 °C and indicated that temperature optimum of light saturated photosynthesis was greater for Glycine max relative to Arabidopsis thaliana or Populus trichocarpa. Transcript profiles were taken at defined states along the temperature response curves and inferred pathway analysis revealed species-specific variation in the abiotic stress and the minor carbohydrate raffinose/galactinol pathways. A weighted gene co-expression network approach was used to group individual genes into network modules linking biochemical measures of the antioxidant system to leaf-level photosynthesis among P. trichocarpa, G. max and A. thaliana. Network enabled results revealed an expansion in the G. max HSP17 protein family and divergence in the regulation of the antioxidant and heat shock module relative to P. trichocarpa and A. thaliana. These results indicate that although the heat shock response is highly conserved, there is considerable species-specific variation in its regulation.

RNA-seq of major tissues and xylem cell types of Populus trichocarpa

Project description:We used the stem cross-sections of P. trichocarpa and our recently developed laser capture microdissection (LCM) to collect fibers, vessels, and a combination of 3 cell types (fibers + vessels + rays). Total RNA from the three samples was isolated, amplified, and analyzed by full-transcriptome RNA-sequencing. The sequencing reads were mapped to the P. trichocarpa genome.

Screen of oligonucleotides for microarray transcriptome analysis of Populus deltoides and P. trichocarpa

Project description:The purpose of this study was to evaluate a set of 6-7 long oligonucleotide probes developed based on the sequence of the Populus trichocarpa genome, that are optimal for gene expression analysis of P. deltoides and a hybrid of P. deltoides and P. trichocarpa. To evaluate these probes, multiple tissues (differentiating xyle, leaf and whole-root) of a pure P. deltoides and a hybrid (P. deltoides X P. trichocarpa) were transcript profiled for identification of one or more probes that are not biased towards one or the other genotype.

Populus trichocarpa Transcriptome or Gene expression

Project description:Our analysis provides a comprehensive picture of how P. trichocarpa responds to drought stress at physiological and transcriptome levels which may help to understand molecular mechanisms associated with drought response and could be useful for genetic engineering of woody plants. Drought stress treatment was performed dividing P. trichocarpa plants into the well-watered (WW) group (soil volumetric water content of 40â45 %) and the water-limited group (soil volumetric water content of 10â15 %). Two cDNA libraries constructed separately from the WW and WL groups were subjected to high-throughput Illumina sequencing.
