Computational modeling of cambium activity provides a regulatory framework for simulating radial plant growth

eLife, 2023
Precise organization of growing structures is a fundamental process in developmental biology. In plants, radial growth is mediated by the cambium, a stem cell niche continuously producing wood (xylem) and bast (phloem) in a strictly bidirectional manner.

Divergent Deborah number-dependent transition from homogeneity to heterogeneity

Nature Communications, 2023
Heterogeneous structures are ubiquitous in natural organisms. Native heterogeneous structures inspire many artificial structures that are playing important roles in modern society, while it is challenging to identify the relevant factors in forming these

A review of wood machining literature with a special focus on sawing [PDF]

, 2013
In this review, fundamental wood machining research is evaluated to determine the general cutting mechanics of simple, orthogonal, and oblique cutting tools. Simple tool force trends and chip formation characteristics are indentified here, along with the

Ecotoxicity and fungal deterioration of recycled polypropylene/wood composites: Effect of wood content and coupling [PDF]

, 2013
Polypropylene (PP)/wood composites were produced by homogenization in a twin-screw extruder and injection molding of tensile bars. Their mechanical properties were determined before and after exposure to biological treatment, and the effect of the ...

Carbon allocation during defoliation: testing a defence-growth trade-off in balsam fir

Frontiers in Plant Science, 2015
During repetitive defoliation events, carbon can become limiting for trees. To maintain growth and survival, the resources have to be shared more efficiently, which could result in a trade-off between the different physiological processes of a plant. The

A Novel NAC Transcription Factor From Eucalyptus, EgNAC141, Positively Regulates Lignin Biosynthesis and Increases Lignin Deposition

Frontiers in Plant Science, 2021
Wood formation is a complicated process under the control of a large set of transcription factors. NAC transcription factors are considered “master switches” in this process.

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.
