Summary: In Arabidopsis thaliana, the proteins CERK1, LYK2, and LYK5 are necessary for chitin-induced resistance to the pathogen B. cinerea, with LYK2 contributing to callose deposition but not essential for chitin perception. LYK2 is also required for enhanced resistance to other pathogens induced by flagellin and for priming of defense gene expression during fungal infection, ensuring robust resistance to subsequent pathogen infections.

Summary: The content of free arginine (Arg) increases when nitrogen (N) nutrition level is high, and this effect is potentiated by additional boron (B) fertilization. This study investigates the effects of soil fertilization with N and B on the accumulation of these elements and free Arg in one-year-old needles of 16-year-old Scots pine trees. It was found that fertilization with 3 kg ha(-1) B at N doses of 200-500 kg ha(-1) stimulates the accumulation of N in needles and increases the level of Arg.

Summary: The study found that drought has effects on carbon partitioning and volatile organic compound synthesis in Scots pine seedlings, reducing the emission of certain sesquiterpenes but not affecting carbon incorporation. Additionally, drought resulted in a re-direction of pyruvate to secondary metabolism pathways, maintaining isoprene and monoterpene production.

Summary: This study investigated ECM fungal communities on bare-root nursery stock of Scots pine in 23 forest nurseries in Poland, revealing that ECM fungal diversity depended on nursery and seedling age. A total of 29 ECM fungal taxa were found on 1- and 2-year-old seedlings, with species richness varying depending on the age of the seedlings.

Summary: This study investigated the variation of mass and surface area of Scots pine needles in different bio-social positions. Allometric equations were derived to determine the relationship between needle mass and surface area with diameter at breast height. The results showed significant correlations between needle mass, surface area, and diameter at breast height.

Summary: The study evaluated the inhibitory effects of citral on three fungal pathogens and revealed that citral changed the morphological characteristics of fungal hyphae, increased membrane permeability and disrupted energy metabolism. Citral also showed positive effects on fruit quality and reduced decay rate, suggesting its potential as an alternative for kiwifruit storage.

Summary: An endophytic bacterium XL17 isolated from a rape crown gall showed potent antagonistic activities against Pseudomonas syringae pv. actinidiae (Psa) and Botrytis cinerea, the devastating diseases of kiwifruit worldwide. Strain XL17 belongs to Pseudomonas bijieensis and produces phenolic polyketide 2,4-diacetylphloroglucinol (DAPG) and cyclic lipopeptides, which can be used to control bacterial canker and gray mold pathogens of kiwifruit.

Summary: The study found that iron deficiency-induced resistance is different from rhizobacteria-induced systemic resistance, it is a plant-mediated defense response that can effectively resist pathogens with different lifestyles. Disruption of iron homeostasis can enhance the plant's immune system for improved defense capabilities.

Summary: Endophytic nitrogen-fixing bacteria have been found in conifer trees in North American boreal forests, which could serve as an important nitrogen source for tree species in nutrient-limited boreal forests. This study investigated the presence and activity of these bacteria in a Scandinavian boreal forest. The results showed that nitrogen-fixing bacteria were present and active in both control plots and fertilized plots, with a calculated nitrogen fixation rate of 20 g N ha(-1) year(-1), suggesting their potential importance for the nitrogen budget of the forest.

Summary: The intensity of light plays a crucial role in the establishment of mycorrhizal symbioses, influencing plant growth, nutrition, and resistance to pathogens. Under different light intensities, mycorrhizal symbioses efficiently reduced disease incidence and severity, providing biotic stress protection regardless of nutritional or growth benefits.

Summary: Endophytic fungi can enhance plant growth and defense against pests and pathogens, reducing the need for chemical pesticides and fertilizers in agriculture. Beauveria bassiana, an entomopathogenic fungus, shows promise as an endophyte in controlling pests and diseases in crops, but the diversity of strains and plant responses should be carefully considered for successful utilization. This study identified B. bassiana strains with potential for tomato endophytic colonization, disease control, and pest management, laying the groundwork for more effective integrated pest management strategies.

Summary: The study found that the content of Hsps in the needles of Scots pine changed in both short-term and long-term after the fire exposure, as well as in response to reheating. The content of Hsps decreased in fire-exposed needles three years later, but increased during the heat stress test, indicating a relatively long-term 'stress memory'.

Summary: This study examined the early fungal succession in young trees and the impact of veteranisation on fungal communities. The results showed that veteranisation resulted in similar fungal communities in young trees compared to old trees, and damaged sapwood and heartwood selected for different fungal communities.

Summary: The study found that the expansion range of Emerald Ash Borer (EAB) in Ukraine is increasing, and European ash trees have stronger resistance to EAB but are more susceptible to dieback disease. The research suggests that it is necessary to inventory and map surviving European ash trees affected by both diseases, in order to carry out long-term restoration work and prevent the invasion of EAB into the EU.

Summary: Ash dieback caused by the alien fungus Hymenoscyphus fraxineus has led to the decline of European ash in Lithuania. However, recent inventories have found naturally regenerated ash stands. A study on these stands revealed that the fungal communities associated with ash were mainly composed of endophytic fungi, some of which may limit the infection rate or spread of H. fraxineus. The diversity of fungal taxa was found to be higher in natural ash habitats compared to planted trials, highlighting the importance of natural habitats in ash restoration programs.

Summary: Recent observations have shown that climate change affects the growth conditions and range of tree species distribution in Europe, which in turn has a major impact on the communities of organisms associated with these tree species. This study aimed to determine whether Larix sp. could provide suitable habitats for insects and lichens associated with P. abies to protect their biodiversity under climate change. The results demonstrate that native P. abies and introduced Larix sp. support similar diversity of stem-associated insect and lichen species.

Summary: The aim of this study was to analyze the seasonal and site-specific patterns of airborne fungal diversity, with a focus on plant pathogens. Passive spore traps were used to collect fungal spores at three different sites in Lithuania over a period of twelve months. High-throughput sequencing revealed the presence of 805 non-singleton fungal taxa, with Ascomycota and Basidiomycota being the most abundant. The diversity of airborne fungi was influenced by surrounding vegetation and climatic factors, while the occurrence of pathogenic fungi was influenced by the availability of hosts.

Summary: The diversity and composition of fungal communities in Pinus sylvestris and Picea abies stands along the latitudinal gradient of these tree species distributions in Europe were assessed to model possible changes imposed by climate change. Results showed that both the latitude and the host tree species had a limited effect on fungal communities, which were primarily influenced by environmental variables and substrate. The predicted shift in fungal communities is towards habitats with a lower temperature amplitude and increased precipitation during the driest month, but the suitability of these habitats is expected to decrease in the future compared to current conditions.

Summary: This study investigated public attitudes towards multi-storey wood buildings in seven European countries and found that the level of knowledge about wood buildings was lower in countries where brick, stone, and concrete were commonly used in construction, such as the United Kingdom, Germany, and Denmark. Finland and Sweden had the most positive attitudes towards wood buildings. The study also identified factors such as fire vulnerability, material solidity, indoor environment, and moisture vulnerability that influenced people's perception of wood buildings as a nice place to live.
