“…Phenylpropanoids pathway contributes to lot of aspects of responses toward environmental stimuli and within vast variety of antioxidant phenolics or produced the defensive component (Fraser and Chapple, 2011;Wang et al, 2021). Specifically, the downstream of phenylpropanoid pathway involves lignin biosynthesis, which is essential for structural integrity and pathogen resistance (Vogt, 2010;Chan et al, 2023). Previously, it was confirmed that transcription factor MeRAV5 promoted the MeCAD15 to affect lignin accumulation which increased drought tolerance in cassava (Yan et al, 2021).…”

Drought-induced leaf senescence is related to high sugar levels in leaves, photosynthesis inhibition, and ultimate yield loss. This physiological phenomenon in leaves bears resemblance to the symptom of diabetes in human disease. However, the underlying mechanisms of plant diabetes on carbon imbalance in maize leaf and corresponding detoxification strategy have not been well understood. In this study, we demonstrated that foliar application of exogenous methylglyoxal (MG) delayed leaf senescence and promoted photoassimilation, retrieved 14% yield loss induced by drought stress during grain filling stage. Transcriptome and metabolite analysis revealed that drought increased sugar accumulation in leaf with inhibition of sugar transporters facilitating phloem loading. This further lead to disequilibrium of glycolysis and over-accumulation of endogenous MG. Contrarily, exogenous MG significantly upregulated glycolytic flux and glyoxalase system catabolizing endogenous MG and advanced glycation end products toxicity, ultimately alleviating plant diabetes. Besides, the genes facilitating anabolism and catabolism of trehalose-6-phosphate were promoted and suppressed by drought, respectively, whereas exogenous MG reversed the effect. Moreover, exogenous MG activated phenylpropanoid biosynthetic pathway, likely promoting cell structural integrity. Collectively, these results suggest that exogenous MG alleviates the toxic effect from drought-induced sugar accumulation and activates the defense-related pathway, thereby maintaining leaf function and yield production.

“…When multi-layer laminated materials are subjected to tension, delamination can occur. In the case of paulownia wood reinforced composites, the parts bearing the load are the ber, matrix, and interface, with the interface being typically more vulnerable to destruction than the matrix and ber [23,24]. This is due to the composite's weak joint nature.…”

Paulownia wood, a fast-growing wood native to China, has limited application due to its loose texture. However, the mechanical properties of materials can be improved by densification after delignification. In this study, paulownia wood was treated with sodium hydroxide and hydrogen peroxide to remove most of the lignin, then densified by hot pressing. The influence of the densification process of paulownia wood/epoxy composite on the mechanical properties, especially stab resistance, was discussed. The results show that densification after delignification significantly improves the mechanical properties of the materials. The densification improves the fracture strength and modulus of the materials, reching 171.98 MPa and 14.55 GPa. Hybrid composites made of densified wood/carbon fiber/epoxy resin have good stab resistance. The punch strength per unit area density and puncture worker unit area density of these hybrid composites are superior to carbon fiber reinforced composites.

“…Bamboo fiber is a kind of natural fiber, and bamboo is rich in resources, with green, low-carbon, recyclable characteristics, thus using bamboo fiber to manufacture bamboo fiber-based composite materials to replace plastic is conducive to the promotion of a green economy and ecological civilization [45,46]. With global warming and increasing environmental threats, forest resources are becoming more and more precious.…”

Natural fiber composites are receiving more and more attention because of their greenness and low cost. Among natural fibers, bamboo is characterized by fast growth, a short cultivation period, high strength and good toughness, and is one of the strongest natural fibers in the world. A bamboo-fiber-reinforced polymer composite (BFRPC) has the characteristics of high mechanical strength, low density, degradability, etc. It has the industrial applicability comparable to metal materials, the same strong corrosion resistance as composites such as glass and carbon fibers, and the same immunity to electromagnetic interference and low thermal conductivity as natural materials. Its unidirectional specific strength and unidirectional specific modulus is higher than that of glass fiber, second only to the extremely high price of carbon fiber, which is playing an increasingly important role in the field of composite materials, and can be widely used in the fields of wind power, construction, aviation, automotive, medical care and so on. At present, it has been initially used in packaging, automotive and transportation fields, and is expected to replace petroleum-based plastics in various fields. In addition to their environmental protection and green production, they have excellent physical properties. This paper provides an overview of the mechanical properties of bamboo-fiber-reinforced thermoplastic composites and thermoset composites that have been developed so far, such as tensile strength, flexural properties and impact strength. In addition, the prospects of bamboo-fiber-reinforced thermoplastic composites for automotive, packaging and agricultural applications are presented.
