Summary: The study revealed differences in the expression of P450 gene families during wood decay among related fungi, indicating a potential role for P450 proteins in niche adaptation. Expansion of certain key P450 gene families and high expression of P450 protein families during wood decay further support the importance of these proteins in wood decay processes. The generalist species S. himantioides was found to have the highest number of P450 genes and family diversity, as well as the highest number of P450 protein families expressed during wood decay.

Summary: The study prepared PVP-Se NPs through wet chemical reduction and characterized their physical and chemical properties using various analytical methods, while also evaluating their toxicological properties. In antifungal experiments, the combination of PVP-Se NPs with a commercial fungicide showed better results than using either alone, demonstrating their synergistic effect and inhibitory effect on fungal growth.

Summary: Lytic polysaccharide monooxygenase (LPMO), specifically the AA14 family, was found to significantly improve the saccharification efficiency of pine and xylan-coated cellulose substrate. The newly identified AA14 LPMO (SlLPMO14A) from brown-rot fungi showed optimal pH, temperature, and reaction activity, and it disrupted the surface structure of lignocellulose to release glucose and xylose.

Summary: The dry rot fungus Serpula lacrymans causes severe structural damage to construction timber, necessitating costly restoration procedures. Research has shown that S. lacrymans harbors various co-existing bacteria, with differences in communities associated with different fungal parts. Some bacteria in co-culture can impact the growth and pigment production of S. lacrymans.

Summary: A study compared the mechanical properties and microstructures of outerwood and corewood of Pinus radiata. The results showed that the outerwood had better performance than the corewood, mainly due to differences in cell wall thickness, MFA, and relative crystallinity.

Summary: This research aimed to study the effect of tensile creep on the longitudinal stiffness of radiata pine wood. The results showed that the moduli of elasticity had no effect on the wood stiffness at the macroscopic level, but there might be changes at the microscopic level.

Summary: This study utilized dynamic mechanical analysis (DMA) to measure the viscoelastic properties of water-saturated radiata pine wood in the temperature range of 0 to 100 degrees Celsius, aiming to understand the transitional behavior within successive annual rings. The results showed that the peak tan delta temperature caused by micro-Brownian motion of lignin varied between different annual rings and within the same ring.

Summary: This study examined the degradation ability of two fungi on thermally modified spruce wood. The results showed that spruce wood treated at higher temperatures exhibited better resistance to the brown-rot fungus compared to the white-rot fungus. The wood samples with higher levels of thermal degradation had larger mass losses and reduced attacks by the fungi.

Summary: In this study, the abundance and composition of prokaryotic communities associated with the fruiting bodies of S. lacrymans were analyzed using amplicon-sequencing. The results showed that microbial diversity was mainly influenced by the specimen type and sample origin. The most abundant bacterial phylum in the fruiting bodies was Pseudomonadota, while Actinomycetota dominated the prokaryote community of the mycelium. Several bacterial genera, including Nocardioides, Pseudomonas, Pseudonochardia, Streptomyces, and Rubrobacter, were found to comprise the core microbiome of S. lacrymans basidiocarps.

Summary: Pinus radiata bark was used as a polyol source for bio-foam production. Alkaline extracts rich in polyphenols were prepared and derivatized to obtain hydroxypropylated alkaline extracts. The hydroxypropylated alkaline extracts showed suitable solubility in polyether and polyester polyols. The study showed that these extracts could be directly applied to bio-foam production without removing salts.

Summary: This study aims to understand the impact of physical properties and chemical composition of Pinus radiata D. Don and Eucalyptus nitens Maiden raw materials on the fibrillation process and final properties of Lignocellulose nanofibrils (LCNFs). The anatomical, physical, and component differences of the fibers did not affect the longitudinal disintegration during the fibrillation process. Smaller fibers produced LCNFs with a smaller average width, particularly in Eucalyptus nitens. The arrangement of components (hemicellulose) from Pinus radiata on the fiber surface resulted in larger and more hydrated fibrils, increasing the viscosities of LCNF suspensions. The glass transition temperatures of lignin were not affected by physical changes in the raw material.

Summary: The construction of robust high-density linkage maps using exome-capture genotyping is significant for genomic research in radiata pine, allowing for quantitative trait locus scans, genomic prediction, and analysis of genetic architecture. The results provide valuable insights into the genomic basis of growth and wood properties in radiata pine.

Summary: Plants have stress memory, and chloroplast signaling is crucial for acquiring and extending this memory. This study examines the impact of the physiological status of Pinus radiata parents on the ability of their progeny to adapt to their first stress period. The results show that seedlings from stressed parents responded quicker and more efficiently, suggesting a potential biotechnological application in seed orchards.
