Compression wood formation in Pinus strobus L. following ice storm damage in southwestern Virginia
To evaluate the compression wood response in eastern white pine (Pinus strobus L.) following a severe ice storm in 1994, 47 trees were felled in 2007 and cross-sectional samples were collected at 0.5 (±0.2) m stem height. The disks were sanded and digitally scanned, and the cross-sectional area …

Development and interrogation of approaches to modelling xylogenesis with a view towards their suitability for inclusion in Dynamic Global Vegetation Models
… via the development and interrogation of wood formation process formulations suitable for resolving hitherto missing growth processes in Dynamic Global Vegetation Models (DGVMs). Current understanding of environmental controls on plant carbon dynamics is encapsulated in DGVMs. These models …

Architecture and Evolution of Xylem-related Gene Coexpression Networks in Poplars
… was used in this study to indentify the genes in wood formation of Populus trichocarpa with the help of the other novel bioinformatics tools such as Gene Ontology and Cytoscape. In order to booster the accuracy of the findings, we have combined it with an evolutionary approach, synonymous and …

Discovery of New Protein-DNA and Protein-Protein Interactions Associated With Wood Development in Populus trichocarpa
… of regulatory mechanisms that control wood development the potential exists to increase biomass yield. Transcription factors (TFs) are DNA-binding regulatory proteins capable of either activation or repression by binding to a specific region of DNA, normally located in the 5-prime …

Development and properties of tracheids and their cell wall layers in eastern hemlock (Tsuga canadensis L.)
… and physical properties, a model for wood formation was derived. The model for wood formation and the physical properties and chemical constitution of the partially developed tracheids were used to calculate physical and chemical properties of individual cell wall layers. Results …

CHARACTERIZING INTRA-ANNUAL XYLEM CELL FORMATION AND CIRCADIAN CYCLE DYNAMICS OF JACK PINE (PINUS BANKSIANA) IN THE NORTHERN BOREAL FOREST, YELLOWKNIFE, NORTHWEST TERRITORIES
Xylem cell formation and stem radial fluctuations for jack pine in Yellowknife, NT were assessed during the 2017 season. The characterization of the timing of the onset of xylogenesis reactivation, period(s) of rapid cell development, and termination of seasonal stem growth were recorded over the …

Functional characterization of NAC-domain transcription factors implicated in control of vascular cell differentiation in Arabidopsis and Populus
Wood has a wide variety of uses and is arguably the most important renewable raw material. The composition of xylem cell types in wood determines the utility of different types of wood for distinct commercial applications. Using expression profiling and phylogenetic analysis, we identified many …

Functional analysis of novel protein-protein interactions involving ROP GTPases in Arabidopsis thaliana and Populus trichocarpa
… protein-protein interactions (PPI) relevant to wood formation. Bait proteins for Y2H binary assays and screening against a xylem cDNA prey library were selected from approximately 400 Populus trichocarpa genes that are at least 8-fold more highly expressed in differentiating secondary xylem …

K+-Homöostase und kaliumabhängige Xylogenese in Populus tremula L. x Populus tremuloides Michx
… von PTORK und PTK2 wurden nach Transformation von A. thaliana mit geeigneten Promotor-GUS-Konstrukten im Phloem und Xylemparenchym von Blattstielen nachgewiesen. Erstmals für Pflanzen wurden mit PTORK und PTK2 Kaliumkanal-Proteine immunologisch durch Antikörper in Phloem- und …

Trockenheitsreaktionen und holzanatomische Eigenschaften der Zitter-Pappel (Populus tremula L.) – Physiologie und QTL-Mapping
Holz aus Kurzumtriebsplantagen (KUP) mit Pappeln (Populus spp.) kann eine bedeutende Rolle im Mix der Bioenergieressourcen in Deutschland spielen. Trotz eines günstigen Energieinput-Energieoutput-Verhältnisses ist das Erreichen wirtschaftlich zufriedenstellender Ergebnisse mit KUP jedoch auf den …
