Systematic Review: Climate and Non-Climate Factors Influencing Wood Density in the Boreal Zone

BioResources, 2023
Wood density is a crucial factor in determining the quality of wood in boreal ecosystems within the Northern Hemisphere. Climate variables play a significant role in shaping wood density, posing challenges for forest managers and stakeholders in the wood

Association studies in Populus tomentosa reveal the genetic interactions of Pto-MIR156c and its targets in wood formation

Frontiers in Plant Science, 2016
MicroRNAs (miRNAs) regulate gene expression in many biological processes, but the significance of the interaction between a miRNA and its targets in perennial trees remains largely unknown.

Genome-Wide Association Studies to Improve Wood Properties: Challenges and Prospects

Frontiers in Plant Science, 2018
Wood formation is an excellent model system for quantitative trait analysis due to the strong associations between the transcriptional and metabolic traits that contribute to this complex process.

Juniper from Ethiopia contains a large-scale precipitation signal [PDF]

, 2008
Most semiarid regions are facing an increasing scarcity of woody vegetation due mainly to anthropogenic deforestation aggravated by climate changes. However, there is insufficient information to reconstruct past changes in climate and to evaluate the ...

Cell wall thickening in developing tension wood of artificially bent poplar trees [PDF]

, 2015
International audienceTrees can control their shape and resist gravity thanks to their ability to produce wood under tensile stress. This stress is known to be produced during the maturation of wood fibres but the mechanism of its generation remains ...

Catalytic graphitization of three-dimensional wood-derived porous scaffolds [PDF]

, 2011
A catalytic technique to enhance graphite formation in nongraphitizing carbons was adapted to work with three-dimensional wood-derived scaffolds. Unlike many synthetic graphite precursors, wood and other cellulosic carbons remain largely disordered after

Wood Anatomy of Gnetales in a Functional, Ecological, and Evolutionary Context [PDF]

, 2012
New scanning electron microscope (SEM) and light microscope data and illustrations are presented in order to compare hydraulic adaptations of non-gnetalean conifers and angiosperms to relevant wood features of Gnetales.

Age-related phenological and anatomical response of European beech (Fagus sylvatica L.) under severe summer drought conditions

Journal of Forest Science
The year 2018 was distinguished by a warm summer with extended periods of low or no precipitation. In this context, we investigated the intra-annual dynamics of xylem differentiation phases and quantitative vessel anatomy to analyse the age effect on the

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
