Summary: This study reveals a mechanism by which a rice enzyme BC16 remodels GPI lipid tails and governs cell wall biomechanics. Loss of BC16 alters GPI lipid structure and disturbs the targeting of GPI-AP BC1 to the cell membrane, leading to compromised cellulosic nanofiber deposition and abnormal mechanical properties. The findings provide insights into the control of cell wall biomechanics and offer potential for breeding crops with improved support strength.

Summary: The study showed that pre-treatment with salicylic acid significantly reduced cadmium accumulation in tomato plants and altered cadmium distribution. Salicylic acid induced the composition of the cell wall, increasing cellulose, hemicellulose, pectin, and lignin content, and up-regulated the expression of lignin and cellulose synthase genes while down-regulating pectin methylesterase related genes. Additionally, salicylic acid decreased pectin methylesterase activity to reduce cadmium accumulation in the cell wall and change cadmium partition ratio.

Summary: In this study, cellulose nanofibril (CNF) films were prepared from ramie fibers with varying pectin compositions and contents, and the impact of residual pectin on the overall performance of CNF films was assessed. The residual pectin composition did not significantly affect the properties of the CNF films obtained. However, increasing the content of residual pectin led to an increase in surface area and water absorption of the CNF films, while decreasing the content resulted in higher UVA light transmittance and tensile strength. This research provides guidance for the preparation of CNF films with different performance requirements.

Summary: In this study, the assembly of lignocellulosic components in plant stems and the interactions between polysaccharides and the aromatic polymer lignin are investigated using solid-state NMR spectroscopy. The research shows that the extent of glycan-aromatic association varies in different types of plant stems, and lignin primarily interacts with xylan through non-covalent interactions and partially binds to the junction of xylan and cellulose surface. The unique feature of homogeneous mixing of all molecules in softwoods enables better water retention. These findings provide insights into the principles of polymer interactions underlying the heterogeneous architecture of lignocellulose, which can guide the rational design of more digestible plants and more efficient biomass-conversion pathways.

Summary: Cellular mechanotransduction plays a critical role in converting mechanical signals to biochemical signals, regulating various biological processes. While mechanical cues can trigger beneficial processes, excessive stimulation can lead to pathological conditions. The regulatory mechanisms between different mechanical cues are not fully understood, and effective therapies targeting mechanical cue-related signaling are lacking.

Summary: Catastrophic events like nuclear war could lead to adverse climate conditions and hinder crop growth. Research shows that converting plant biomass into food at 30% efficiency would provide enough carbohydrates but might result in potentially toxic or insufficient levels of other nutrients. Therefore, utilizing biomass with low mineral content for carbohydrates and supplementing with edible insects/single-cell proteins and vitamin supplements could offer a balanced diet in a global catastrophic environment.

Summary: Fungal infections pose a significant threat to human health, especially for immunocompromised individuals. However, our understanding of the assembly and remodeling of fungal cell walls has been limited. High-resolution solid-state nuclear magnetic resonance (ss NMR) studies have provided new insights into the structure of polysaccharides and the organization of cell walls in Aspergillus fumigatus and other fungi. In this study, the dynamic nuclear polarization (DNP) technique was used to compare the cell wall materials of A. fumigatus and C. albicans. The results confirmed the presence of a conserved carbohydrate core in the cell walls of both fungi, regardless of the culture media used. Additionally, the discovery of the function of alpha-glucan in forming the mechanical centers was validated. These findings not only contribute to our understanding of A. fumigatus cell walls at different stages but also have implications for the study of other challenging fungal materials and cellular systems.
