Summary: This study investigated the extraction, emulsifying properties, and biological activities of polysaccharides from Lentinula edodes Sing (LES). The results showed that LES polysaccharides extracted by hot water had the best emulsifying capacity, while the ones extracted by 90 min ultrasonication exhibited the strongest antioxidant activities. Therefore, Lentinula edodes Sing polysaccharides may have potential applications as emulsifying agents in the food industry.

Summary: Aspergillus fumigatus is a deadly opportunistic fungal pathogen causing hundreds of thousands of deaths every year. Our study reveals that phosphoglucose isomerase (PGI) plays an important role in the growth, cell wall biosynthesis, and virulence of A. fumigatus. The crystal structure of PGI provides a foundation for the development of PGI as a potential antifungal target.

Summary: Plant cell walls are crucial for plant growth and adaptation to environmental stresses. Plants have evolved signaling mechanisms to maintain cell wall integrity, which can be activated by environmental and developmental signals. While the signaling pathways associated with environmental stress have been well studied, less attention has been given to cell wall integrity signaling in relation to normal plant growth and development. This review focuses on the role of cell wall integrity signaling in fruit ripening, including the signaling pathways involved in cell wall fragment, calcium, and NO signaling, as well as the involvement of Receptor-Like Protein Kinases (RLKs), specifically FERONIA and THESEUS, in hormone signal regulation during fruit development and ripening.

Summary: Plant cell walls are complex structures that surround all plant cells and play important roles in providing support, protection, and maintaining integrity. Recent studies have shown that plants have a dedicated mechanism to monitor and repair cell wall damage caused by growth, development, and various stresses. This mechanism involves mechano-perception, reactive oxygen species, and phytohormone-based signaling processes. Additionally, there is crosstalk between cell wall integrity maintenance and pattern triggered immunity, which modulates adaptive responses to biotic stress. The review focuses on Arabidopsis thaliana and discusses the conservation of these mechanisms in other plant species as well as the transcriptional machinery responsible for controlling adaptive responses.

Summary: The liquid phase is an important influencing factor in Solid-State Fermentation (SSF), and water control is crucial. Super absorbent polymer (SAP) is used to supply water, and its addition significantly increases biomass and enzyme activity. The water states of fermentation substrates were analyzed using low-field nuclear magnetic resonance (LF-NMR), revealing that capillary water dominates water present and lost. The capillary water content has a high correlation with biomass and enzyme activities.

Summary: Putrescine (Put) plays a regulatory role in cell growth, and its regulation in fungi, particularly in the biosynthesis of ganoderic acid (GA), involves interactions with ornithine decarboxylase (ODC) proteins and the antizyme (AZ) protein. The target of rapamycin (TOR) can promote Put accumulation and affect GA biosynthesis by inhibiting the level of AZ protein. This study provides insights into the regulatory mechanisms of Put and secondary metabolism in fungi.

Summary: Our study revealed the interaction between GCN4 and SKO1 in regulating nitrogen utilization through affecting the transcription level of areA. GCN4 activates transcription by directly binding to the promoter recognition region of areA, while SKO1 facilitates areA transcription by forming a more stable complex with GCN4. This study deepens our understanding of the regulatory network of nitrogen metabolism and demonstrates a further level of regulation for transcription factors.

Summary: This study aimed to investigate the feasibility of developing impact-resistant mycelium-based composites (MBCs) using agricultural waste straws such as rice straw, wheat straw, and corn straw. The physical properties and performance of MBC specimens were tested and analyzed, including density, elasticity modulus, thermal conductivity, compressive strength, and impact resistance. The results showed that MBCs made from rice straw and wheat straw had higher compressive strength and impact resistance compared to those made from corn straw, attributed to the low degree of fermentation due to the flaky shape of corn straws.
