The contribution of G-layer glucose in Salix clones for biofuels: comparative enzymatic and HPLC analysis of stem cross sections. [PDF]

Biotechnol Biofuels Bioprod, 2022
Abstract Background Interest on the use of short rotation willow as a lignocellulose resource for liquid transport fuels has increased greatly over the last 10 years. Investigations have shown the advantages and potential of using Salix spp.

Transcriptomics and Proteomics Reveal the Cellulose and Pectin Metabolic Processes in the Tension Wood (Non-G-Layer) of Catalpa bungei. [PDF]

Int J Mol Sci, 2020
Catalpa bungei is an economically important tree with high-quality wood and highly valuable to the study of wood formation. In this work, the xylem microstructure of C. bungei tension wood (TW) was observed, and we performed transcriptomics, proteomics and Raman spectroscopy of TW, opposite wood (OW) and normal wood (NW).

Toward identifying molecules responsible for the peculiar properties of the G-layer in tension wood fibres [PDF]

BMC Proc, 2011
Background Due to its peculiar properties, tension wood formation constitutes a remarkable adaptation mechanism, that makes possible for the tree to reorientate its axes (stem and branches) in response to environnemental cues. In poplar, tension wood fibres harbour an extra cell wall layer, the G-layer, responsible for the peculiar mechanical ...

The effect of the G‐layer on the viscoelastic properties of tropical hardwoods [PDF]

Annals of Forest Science, 2012
Context and aim : This study aimed to examine the effect of the tension wood G‐layer on the viscoelastic properties of wood. Methods : Tension wood and opposite wood samples were obtained from six French Guianese tropical rainforest species (Sextonia rubra, Ocotea guyanensis, Inga alba, Tachigali melinoni, Iyranthera sagotiana and Virola michelii); the

Evidence of the late lignification of the G-layer inSimaroubatension wood, to assist understanding how non-G-layer species produce tensile stress [PDF]

Tree Physiology, 2015
To recover verticality after disturbance, angiosperm trees produce 'tension wood' allowing them to bend actively. The driving force of the tension has been shown to take place in the G-layer, a specific unlignified layer of the cell wall observed in most temperate species. However, in tropical rain forests, the G-layer is often absent and the mechanism

Growth Stresses are Highly Controlled by the Amount of G-Layer in Poplar Tension Wood [PDF]

IAWA Journal, 2008
To determine how gelatinous fibres and gelatinous layers contribute to the magnitude of longitudinal growth stress in tension wood, anatomical measurements of gelatinous fibres were carried out on poplar tension wood (Populus I4551). It was found that (a) no gelatinous fibres were observed under a growth strain level of 0.06 to 0.08%; (b) almost 100 ...

Stress generation in the tension wood of poplar is based on the lateral swelling power of the G‐layer [PDF]

The Plant Journal, 2008
SummaryThe mechanism of active stress generation in tension wood is still not fully understood. To characterize the functional interdependency between the G‐layer and the secondary cell wall, nanostructural characterization and mechanical tests were performed on native tension wood tissues of poplar (Populus nigra × Populus deltoids) and on tissues in ...

Sustainable silicon anodes facilitated via a double‐layer interface engineering: Inner SiOx combined with outer nitrogen and boron co‐doped carbon

Carbon Energy, 2022
Silicon‐based (Si) materials are promising anodes for lithium‐ion batteries (LIBs) because of their ultrahigh theoretical capacity of 4200 mA h g−1. However, commercial applications of Si anodes have been hindered by their drastic volume variation (∼300%)
