Summary: Gray mold caused by Botrytis cinerea is a devastating disease in tomatoes. The combined application of Clonostachys rosea and newly developed succinate dehydrogenase inhibitors (SDHI) fungicides showed stronger synergistic effects on tomato gray mold control than the application of SDHI fungicides alone. In greenhouse experiments, the combination of C. rosea with fluxapyroxad or fluopyram significantly increased the control effect against tomato gray mold, allowing a two-fold reduction of both the fungicide and biological control agent (BCA) dose.

Summary: In this study, the endophytic ability and growth effect of Clonostachys rosea strain ST1140 on solanaceous plants were tested. The study also investigated different organic substrates for cultivating and multiplying the strain. The results showed that inoculating seeds with ST1140 resulted in faster and better seed germination and plant growth compared to non-inoculated controls.

Summary: In this study, Clonostachys rosea was successfully immobilized using nontoxic chemical material sodium alginate, which enhanced its efficiency in suppressing gray mold and promoting tomato growth. The immobilized C. rosea effectively inhibited the growth of gray mold and increased the activity of stress-related enzymes and photosynthetic efficiency in tomatoes. These results indicate that immobilization improved the stability of C. rosea without compromising its biocontrol efficacy and tomato growth promotion. The findings of this research can serve as a foundation for further research and development of new immobilized biocontrol agents.

Summary: This study assessed the potential of two biocontrol fungal agents, Trichoderma harzianum and Clonostachys rosea, in preventing and alleviating B. cinerea infection. The results showed that both biocontrol agents had significant fungicidal effects on all tested phytopathogens and reduced the establishment of B. cinerea. Furthermore, a combination of both biocontrol agents showed better control of B. cinerea in tomato plants.

Summary: The Montreal Protocol and its Amendments have been highly effective in protecting the stratospheric ozone layer, reducing global warming, and preventing global increases in UV-B radiation. However, ongoing and projected changes in UV-B radiation and climate still pose threats to human health, ecosystems, and construction materials.

Summary: The study utilized community science data on eastern gray squirrels in 43 North American cities to investigate the relationship between urbanization and melanism. The results showed that the prevalence of melanism was positively associated with urbanization, with urban-rural clines in melanism being strongest in large cities with extensive forest cover and weakest or absent in cities with warmer winter temperatures. These findings suggest that novel traits can evolve in a highly repeatable manner among urban areas, but are modified by factors intrinsic to individual cities.

Summary: Solar ultraviolet-B (UV-B) radiation has been crucial for life’s evolution on Earth. UV exposure to humans has both risks and benefits, which are difficult to determine due to environmental and physiological factors. This review discusses the effects of UV-B radiation on humans and the mechanisms controlling its levels. It also reveals the uncertainties in future levels caused by climate change, emphasizing the need for continued precautionary measures to protect against excess UV-B exposure.

Summary: Downy mildew and gray mold are fungal diseases that significantly impact grape production worldwide. Cytochrome b plays a significant role in the mitochondrial respiratory chain of the fungi causing these diseases and is a key target for fungicide development. Using a combination of fungicides can reduce the development of resistance. This study identified the most potent QoI-based fungicide combinations for different fungal mutations through simulation and machine learning algorithms.

Summary: Land use and climate change have an impact on species distributions globally. In this study, the authors used observation data from gray wolves in the western Great Lakes region to predict how land use and climate change may affect wolf habitat. The results suggest that there will be stable or increasing amounts of wolf habitat in the region during the 21st century, with limited adverse effects on current distribution or further recolonization of wolves. These findings can guide wolf conservation policies and promote human-wolf coexistence.

Summary: An in situ mesocosm experiment in a Mediterranean lagoon showed that the frequency of marine heatwaves is expected to increase in the future. The first heatwave significantly increased various indicators of biological processes, such as gross primary production, respiration, chlorophyll-a, phytoplankton growth, and loss rates. The second heatwave shifted the system towards heterotrophy by enhancing respiration. Both heatwaves also altered the phytoplankton community structure.

Summary: Climate change has significant impacts on the distribution of fungal species, particularly on the common black mold Aspergillus niger. By utilizing a large dataset and modeling tools, researchers have found that temperature is the most important climatic parameter influencing the distribution of this fungus. Global warming will impose limitations on the range of Aspergillus niger.

Summary: The COVID-19 pandemic has led to increased interest in the diagnosis and treatment of infectious diseases. Nuclear medicine, with its powerful imaging modalities, has always played a crucial role in diagnosing infections and distinguishing them from sterile inflammation. Efforts have been made to develop more specific imaging agents, such as radiolabeled antibiotics and antimicrobial peptides, for bacterial imaging, as well as radiolabeled anti-fungals for fungal infections imaging.

Summary: The azo dye Congo Red (CR) is commonly used to induce cell wall integrity stress in fungi. This toxic compound undergoes pH-dependent structural changes and can precipitate at low pH, affecting its toxicity. The growth of Aspergillus nidulans and Aspergillus niger was found to be affected by CR in a pH-dependent manner. Buffering the solutions at pH above 5 is recommended for studying the antifungal effect of CR, while lower pH is suggested for decolorization of CR solutions.

Summary: Little is known about the impact of hypoxia and anoxia during mycelial growth on tolerance to different stress conditions of fungal conidia. This study found that conidia produced under hypoxic conditions exhibited higher tolerance to oxidative stress, osmotic stress, and UV radiation, while conidia produced under transient anoxic conditions showed higher tolerance to osmotic stress and UV radiation. Nutritional stress induced the highest levels of tolerance to heat, oxidative stress, osmotic stress, and UV radiation. Overall, growth under hypoxia and anoxia resulted in conidia with higher stress tolerances.

Summary: All fungi emit volatile organic compounds (VOCs) during growth, which vary in composition depending on the species, age, and environmental parameters. These VOCs include alcohols, aldehydes, acids, ethers, esters, ketones, terpenes, thiols, and their derivatives, and contribute to the characteristic odors associated with molds, mushrooms, and yeasts. Some volatiles, like 1-octen-3-ol, have biological activities as germination inhibitors, plant growth regulators, and semiochemicals in interactions with arthropods. Despite their importance, volatiles are understudied and underappreciated elements in fungal chemical metabolism.

Summary: Soybean, corn, and cotton crops are plagued by noctuid pests, but the development of bio-insecticides, such as the fungus Metarhizium rileyi, shows promise in controlling these pests. However, insect-pathogenic fungi used in agriculture face challenges from UV-B radiation and solar heat, which greatly reduce their survival rate. This study evaluated the UV-B tolerance of different isolates of M. rileyi and compared them to other Metarhizium species. The results showed variability in UV-B tolerance among the isolates, with some demonstrating high tolerance levels similar to the most tolerant Metarhizium species. Overall, most M. rileyi isolates could endure 1-2 hours of UV-B exposure, but their germination rates significantly decreased after 3 hours.
