“…Analysed pit channels in the developing shell were simple tubes with a mean size of about 1 µm in diameter but showed high variability depending on the interfaces. At the ICS interface, pit fields were in the size range found in maize and Arabidopsis with around 150 nm (Fujita and Wasteneys 2014 ; Mueller and Brown 1982 ) or in bamboo ranging from 100 to 300 nm (Chen et al 2020 ). Pit fields at the husk interface were more similar to pitted metaxylem cells with a pit diameter of about 2 µm (Fujita and Wasteneys 2014 ).…”

Main conclusion High symplastic connectivity via pits was linked to the lignification of the developing walnut shell. With maturation, this network lessened, whereas apoplastic intercellular space remained and became relevant for shell drying. Abstract The shell of the walnut (Juglans regia) sclerifies within several weeks. This fast secondary cell wall thickening and lignification of the shell tissue might need metabolites from the supporting husk tissue. To reveal the transport capacity of the walnut shell tissue and its connection to the husk, we visualised the symplastic and apoplastic transport routes during shell development by serial block face-SEM and 3D reconstruction. We found an extensive network of pit channels connecting the cells within the shell tissue, but even more towards the husk tissue. Each pit channel ended in a pit field, which was occupied by multiple plasmodesmata passing through the middle lamella. During shell development, secondary cell wall formation progressed towards the interior of the cell, leaving active pit channels open. In contrast, pit channels, which had no plasmodesmata connection to a neighbouring cell, got filled by cellulose layers from the inner cell wall lamellae. A comparison with other nut species showed that an extended network during sclerification seemed to be linked to high cell wall lignification and that the connectivity between cells got reduced with maturation. In contrast, intercellular spaces between cells remained unchanged during the entire sclerification process, allowing air and water to flow through the walnut shell tissue when mature. The connectivity between inner tissue and environment was essential during shell drying in the last month of nut development to avoid mould formation. The findings highlight how connectivity and transport work in developing walnut shell tissue and how finally in the mature state these structures influence shell mechanics, permeability, conservation and germination.

“…In a previous study, Wu et al separated three new lignin glycosides from Castanea ehnryi and two known lignins [25]. The structure of the isolated lignin was mainly 2,3-dihydro-2-[4-(β-glucopyranosyl (1,2)-[β-glucopyranosyl (1,6)]-β-glucopyranosyloxy)-3-methoxyphenyl]-3-(hydroxymethyl)-7-methoxy5benzofuranpropanol and it was reported that all of them inhibited tyrosinase. In another study, six lignin samples (obtained by alkali and ethanol extraction from three typical lignocellulosic materials) showed excellent tyrosinase inhibitory effects [15].…”

“…They are primarily distributed across tropical and subtropical zones, with some in the temperate and frigid zones. Their fast and rhizomatous growth habits are suitable for industrial production because they can be harvested within 4-5 years; furthermore, they can continue growing from the remaining part of their stems in the ground after annual harvests [6]. Bamboo biomass is generally used to manufacture handicrafts and as construction materials, pulp materials, and food ingredients [7].…”

Cosmetic ingredients originating from natural resources have garnered considerable attention, and the demand for whitening ingredients is increasing, particularly in Asian countries. Lignin is a natural phenolic biopolymer significantly effective as a natural sunscreen, as its ultraviolet protection efficacy ranges from 250 to 400 nm. However, using different types of lignin as cosmetic ingredients is difficult owing to the heterogeneity of lignin and the lack of in vitro and in vivo safety and efficacy data. Thus, steam-exploded lignin (SEL) was prepared from bamboo, fractionated via successive organic solvent extraction, and sequentially fractionated using ethyl acetate, methanol, and acetone to investigate its potential as a natural whitening material. Gel permeation chromatography showed that the molecular weight of acetone-soluble and acetone-insoluble SEL fractions were the lowest and the highest, respectively. Monomer structures of the four lignin fractions were elucidated using 1H, 13C, and 2D heteronuclear single quantum coherence nuclear magnetic resonance and pyrolysis gas chromatography/mass spectrometry. The antioxidant and tyrosinase inhibition activities of the four fractions were compared. The methanol-soluble SEL fraction (SEL-F2) showed the highest antioxidant activity (except 2,2-diphenyl-1-picrylhydrazyl scavenging activity), and the enzyme inhibition kinetics were confirmed. In this study, the expression pattern of the anti-melanogenic-related proteins by SEL-F2 was confirmed for the first time via the protein kinase A (PKA)/cAMP-response element-binding (CREB) protein signaling pathway in B16F10 melanoma cells. Thus, SEL may serve as a valuable cosmetic whitening ingredient.

“…The dyeing process in the hot water bath for three days could be also considered to be a heat treatment, which is used to increase the dimensional stability of wood products (Zhang et al 2013a). Previous studies (Hu et al 2014;Liu et al 2020) have shown that dyeing at higher temperatures increases the color fastness of the material. Higher temperatures can increase the reactivity and bonding between dye molecules and free radicals on the material surface (Hu et al 2014).…”

“…Bamboo is a highly functionally graded composite with unique and different material characteristics to wood. Moso bamboo is a hollow culm with dense and waxy outer walls, with the tissue lacking crossgain pores or large pits (Chen et al 2020), which makes it much more difficult to treat with preservatives, stains and dyes, chemical modification agents or adhesive resins compared with wood. Therefore, significant culm crushing and flattening are needed to improve bonding and further treatment of bamboo fiber composites.…”

Flattened and crushed fiber-bundles of moso bamboo (Phyllostachys pubescens) were dyed with a water or alcohol-based dye at 20 °C, 75 °C or 90 °C for 72 h, followed by drying and coating with PF resin. Hot-pressed bamboo fiber composites (BFC) were manufactured, and the weathering performance of the composites made from dyed and natural bamboo material were tested over 90 days of the Autumn/Winter season in Beijing. Dye was able to penetrate the bamboo tissue to create a rich red color that degraded in color faster than BFC made from un-dyed bamboo. BFC made from un-dyed tissue remained a lighter but more consistent color over the weathering period. Dying the bamboo in ethanol-based dye was effective at pigmenting the product, but made it more susceptible to color degradation as well as greater mass and thickness loss due to the chemical degradation of the lignin caused by ethanol. Higher temperature of water dying treatment (90 °C) gave the greatest resistance to mass and thickness loss during outdoor exposure, and the bamboo may have benefitted from the longer period of ‘heat treatment’ during dyeing. Further work is needed to quantify dye leaching from bamboo tissue and to develop more water-tight and color-fast, weather resistant dyes for bamboo products.
