“…Nettle is a wide-spread plant in the wild, requiring almost no extra watering or care, thus making it an excellent biodegradable source for fibre production (Markova 2019). This ecological aspect combined with other advantageous traits such as its nontoxicity, processability and ability to be recycled, have contributed to the popularity and increasing utilization of nettle fibres and yarn products (Debnath 2015). Nowadays, the interest in plant fibres and fibreformed structures is not only limited to textiles as some common plant fibres have turned out to be very functional materials for biocomposites due to their useful mechanical properties (Ramamoorthy et al 2015).…”

Stinging nettle (Urtica dioica) is a potential source material for industrial applications. However, systematic research on the ultrastructural properties of nettle fibres is lacking. Determining the ultrastructure of nettle and the other bast fibres also provides new insights into the studies of archaeological fibres and their usage. In this study, the nanostructure of modern and ancient nettle samples was studied using wide-angle X-ray scattering (WAXS) and compared to other bast fibres. The culturo-historical fibre samples consisted of nettle, flax, and hemp from White Karelian textiles collected 1894 as well as of 800–900-year-old archaeological textile fragments from Ravattula Ristimäki burial site, Finland. Using WAXS, the average cellulose crystallite widths, relative crystallinities and orientational order (including microfibril angle for the modern fibres) were determined and compared. The results also revealed the suitability of the WAXS analysis for fibre identification. The crystallite widths were of the similar size for all modern fibres (3.4–4.8 nm). Subtle differences in the relative crystallinities in descending order (from flax to nettle, and finally hemp) were observed. Also, subtle differences in the mean MFAs were observed (10 ± 1° for flax, 12 ± 1° for nettle, and 14 ± 1° for hemp). For the culturo-historical fibres, the values for crystallite widths and relative crystallinities were larger compared to the corresponding modern references. In addition, features due to the presence of non-cellulosic, crystalline substances (e.g., calcium oxalates) were detected in the WAXS patterns of all the modern nettle fibres. These features could potentially be used as a tool for identification purposes. Graphical abstract

“…Plants that produce bast fibers are extremely important because they provide both long and strong fibers containing high amounts of crystalline cellulose . These fibers have applications in the textile industry, as well as in the biocomposite industry, being environmentally friendly alternatives to artificial fibers [ 28 ]. Flax ( Linum usitatissimum L.), hemp ( Cannabis sativa L.) and nettle ( Urtica dioica L.) are fibrous plants that have attracted more interest as producers of fiber cells with gelatinous cell walls, high crystalline cellulose content and low lignin content [ 29 , 30 ].…”

Sucrose synthase is a key enzyme in sucrose metabolism as it saves an important part of sucrose energy in the uridine-5′-diphosphate glucose (UDP-glucose) molecule. As such it is also involved in the synthesis of fundamental molecules such as callose and cellulose, the latter being present in all cell walls of plant cells and therefore also in the gelatinous cell walls of sclerenchyma cells such as bast fibers. Given the importance of these cells in plants of economic interest such as hemp, flax and nettle, in this work we have studied the occurrence of Sucrose synthase in nettle stems by analyzing its distribution between the cytosol, membranes and cell wall. We have therefore developed a purification protocol that can allow the analysis of various characteristics of the enzyme. In nettle, Sucrose synthase is encoded by different genes and each form of the enzyme could be subjected to different post-translational modifications. Therefore, by two-dimensional electrophoresis analysis, we have also traced the phosphorylation profile of Sucrose synthase isoforms in the various cell compartments. This information paves the way for further investigation of Sucrose synthase in plants such as nettle, which is both economically important, but also difficult to study.

Stinging nettle (Urtica dioica) among other bast fibres, is a potential fibre source material for industrial and manufacturing applications. However, systematic research on the ultrastructural properties of nettle fibres is lacking. Determining the ultrastructural parameters of the bast fibres could provide also new insights into the studies of archaeological and historical fibres and their usage. In this study, modern and ancient fibre samples of stinging nettle were studied using wide-angle X-ray scattering (WAXS) and compared to other well-studied plant fibre species. From the WAXS patterns, the mean microfibril angle, average cellulose crystallite width and relative crystallinity index were determined. Besides, the suitability of the WAXS method for fibre identification purposes was studied. The culturohistorical research material consisted of fibre samples of nettle, flax and hemp acquired from White Karelian textiles collected 1894 as well as of 800–900-year-old archaeological textile fragments from Ravattula Ristimäki burial site in Kaarina, Southwest Finland. The crystallite widths for all modern fibres were of the similar size, however subtle differences in the relative crystallinity values in descending order (from flax to nettle and finally hemp) were observed. For the culturohistorical fibres, the values for average crystallite width and relative crystallinity were larger compared to the modern references of the same fibre type. In addition, individual features due to the presence of other crystalline substances (noncellulosic, minerals e.g., calcium oxalates), were detected in the scattering patterns of all modern nettles. These features could potentially be used as a tool to identify modern nettle fibres.
