Effectiveness in woody biomass utilization is highly dependent on its genetics and physiology. We performed morpho-anatomical, chemical, and biomethane productivity characterizations of one-year-old woody stems in three shrub Salix viminalis genotypes: a diploid (Energo) and its two autotetraploid derivatives (PP-E7 and PP-E13). Tetraploidization a...

In nature, woody substrates are usually degraded by entire communities of microorganisms, which are nowadays jeopardised by anthropogenic influence, making it important to define the functional specificity of every species. Two strains of autochthonous fungi from Serbian lowland forests (Pleurotus ostreatus Ser1 and Cyclocybe aegerita Ser1) have be...

Leaning stems of woody plants form reaction wood, in hardwood trees termed tension wood (TW). Typical TW fibers, gelatinous fibers (G-fibers), are characterized by an inner gelatinous cell wall layer (G-layer). Xyloglucan endotransglycosylases (XETs) was proposed as the essential enzyme in cell wall modifications in TW, by making xyloglucan (XG) cr...

Modern light microscopy imaging techniques have substantially advanced our knowledge about the ultrastructure of plant cells and their organelles. Laser-scanning microscopy and digital light microscopy imaging techniques, in general—in addition to their high sensitivity, fast data acquisition, and great versatility of 2D–4D image analyses—also open...

The UV-B represents the minor fraction of the solar spectrum, while UV-C is not contained in natural solar radiation, but both radiation types can cause damaging effects in plants. Cell walls (CWs) are one of the targets for external stressors. Juvenile P. omorika trees were treated either with 21 day- high doses UV-B or with 7 day- UV-C in open-to...

Cellulose, xylan and lignin, as well as maize cell wall, were used as modifiers of carbon paste electrode. Comparative analysis of electrochemical performance of each modifier toward heavy metal detection was performed. A higher affinity of biomass constituents for lead ions than for copper ions influenced simultaneous detection of lead and copper...

Key message We present and test an automatic image processing morphometric method for the analysis of tracheid double wall thickness. Abstract Measurements of various anatomical characteristics of wood cells are of great importance in research of wood structure, either for the evaluation of environmental influences or for estimation of wood qualit...

Anatomical adaptation of liana plants includes structural changes in cell walls of different tissues: fibers, vessel elements and tracheids. However, the contribution of parenchyma cells to stem twining in liana plants is mostly unknown. The aim of this investigation is to determine changes in stem parenchyma cell walls that are correlated with the...

Interactions between macromolecules in the cell walls of different plant origin were compared, namely spruce wood (Picea omorika (Pančić) Purkiňe) as an example of softwood, maple wood (Acer platanoides L.) as a hardwood and maize stems (Zea mays L.) as a herbaceous plant from the grass family and widely used agricultural plant. Interactions of mac...

Fluorescence-detected linear dichroism (FDLD) microscopy provides observation of structural order in a microscopic sample and its expression in numerical terms, enabling both quantitative and qualitative comparison among different samples. We applied FDLD microscopy to compare the distribution and alignment of cellulose fibrils in cell walls of com...

Key message Young P. omorika trees subjected to static bending showed a severe compression wood response as characterized by fluorescence spectroscopy/microscopy, which decreased in severity with height correlated with a decrease in bending moment. Abstract This investigation is aimed at understanding the reaction wood response in a slow-growing co...

Main conclusion: Cell wall fluorescence and immunocytochemistry demonstrate that xylem parenchyma cell walls do not show changes in structure and composition related to gravitropic response comparable to those of tracheids, even when they have lignified secondary cell walls. Tracheid cell walls in compression wood have altered composition and stru...

Cell-wall mechanical properties play a key role in the growth and the protection of plants. However, little is known about genuine wall mechanical properties and their growth-related dynamics at subcellular resolution and in living cells. Here, we used atomic force microscopy (AFM) stiffness tomography to explore stiffness distribution in the cell...

In a plant cell wall, lignin is synthesized from several monomeric precursors, combined in various ratios. The variation in monomer type and quantity enables multifunctional role of lignin in plants. Thus, it is important to know how different combinations of lignin monomers impact variability of bond types and local structural changes in the polym...

The organisation of the major polymers in the wood fibre structure has a large impact on the properties of the structure. Numerous studies have been devoted to the cellulose microfibril arrangement, the structure providing the longitudinal strength of the fibre, while less is known regarding the structural organisation of the other components, the...

The organization of the major polymers in the wood fiber has a large impact on the properties of the structure. Numerous studies have been devoted to the cellulose microfibril arrangement, providing the longitudinal strength of the fiber, while less is known regarding the structural organization of other components, such as hemicelluloses and ligni...

The mechanical and physical properties of wood fibres are dependent on the organisation of their constituent polymers (cellulose, hemicellulose and lignin). Fourier Transform Infrared (FTIR) microscopy was used to examine the anisotropy of the main wood polymers in isolated cell wall fragments from branches of maple and Serbian spruce. Polarised FT...
