Summary: Tropical regions are important for studying the potential impact of global climate change on forest ecosystems, including the essential ecological functions of bryophytes. A study in southern China showed that terrestrial moss species transplanted to warmer and drier elevations experienced severe declines in health status and growth, with some species highly susceptible to changes in temperature and rainfall patterns. As the tropics are expected to become hotter and drier, terrestrial mosses may face negative impacts and potential extinction, highlighting the role of bryophytes in reflecting the adverse effects of climate change and providing early warnings of biological outcomes.

Summary: This study discusses the diversity of fungal secondary metabolites that are phytotoxic to weeds and the methods commonly used to extract, characterize, identify and exploit them for weed management. The 183 phytotoxic fungal secondary metabolites identified in this review have different toxic effects on plants, including inhibition of germination, root and vegetative growth, and tissue and organ alterations. The biochemical characterization of these metabolites requires specialized knowledge and tools, as well as toxicity tests and effectiveness evaluations in laboratory and field conditions.

Summary: Harmful algal blooms events have been increasingly frequent and intense due to climate change and nutrient inputs from human activities. A method based on LC-HRMS was developed to detect and identify cyanobacterial metabolites in bloom samples from Lake Karaoun, Lebanon. A total of 92 cyanometabolites were annotated, including 7 newly discovered cyanobacterial metabolites. The study also recorded the presence of anthropogenic contaminants, highlighting the need for assessment of the co-occurrence of cyanotoxins and other hazardous compounds in the environment.

Summary: Microbes, particularly cyanobacteria, produce a variety of secondary metabolites with therapeutic potential. These metabolites could be potential options for COVID-19 treatment due to their demonstrated pharmacological actions against various pathogens. Numerous cyanobacterial metabolites have shown activity against bacteria, fungi, viruses, and tumor cells, making them valuable candidates for the development of medicinal molecules.

Summary: This study analyzed the dynamics of lichen and bryophyte communities in two dry sandy grasslands in Hungary, and investigated the effects of management changes on these cryptogams. The results showed that fencing led to an increase in cryptogam biomass, with lichens benefiting more than bryophytes. The long-term absence of grazing resulted in a significant increase in lichen biomass, while moderate grazing favored a legally protected lichen species. Short spells of low-intensity grazing can promote species richness of cryptogams.

Summary: Free radicals are crucial in cellular chemical processes, but many synthetic antioxidants are known to be carcinogenic. Natural antioxidants without side effects are being sought, and lichens containing phenolic compounds may be suitable candidates. This study aims to compare the activity of metabolites involved in radical scavenging using micromolar concentration calculations.

Summary: For the first time, a macrophyte-based assessment of ecological status was related to the accumulated heavy metals and trace elements in aquatic plants. Three moss and two vascular plant species were applied as biomonitors and three streams were found to be in good ecological status with low contamination. Two sites in moderate ecological status were revealed to be heavily contaminated with trace elements.

Summary: Despite the widespread use of lichens as biomonitors of airborne trace elements, the surface chemistry and metal adsorption parameters of these organisms are still poorly understood. This study quantified the acid-base surface properties and metal adsorption of Pseudevernia furfuracea, and found that lichen samples had higher metal-binding site concentrations compared to mosses. Although the adsorption parameters of lichens were lower than mosses, they were still able to adsorb the same amount of Cu2+ and more Zn2+.

Summary: The Chernobyl nuclear disaster released large amounts of radionuclides, which can still be detected in plants and sediments today. This study focused on moss samples from different locations and found high concentrations of Cs-137 and Am-241, with Cs-137 being significantly higher in the cooling pond. The results suggest that mosses accumulate radionuclides indiscriminately, while Cs-137 can be washed out from the soil over time, Am-241 remains adsorbed to the topsoil and precipitates in the cooling pond.

Summary: This study analyzed the potential effects of extracts from lichens and their secondary metabolites on proliferation, antimicrobial activity, and antioxidative activity. The results showed that both the extracts and the isolated compounds exhibited strong antiproliferative and cytotoxic activity against various cancer cell lines in both 2D and 3D models. Additionally, they demonstrated antioxidant and antimicrobial potential. The study highlights the importance of 2D and 3D models in drug discovery and emphasizes the promising effects of lichen compounds.

Summary: This article explores the phenotypic responses of mosses to environmental signals such as light, temperature, CO2, water, nutrients, and gravity, and compares them with the known responses in vascular plants. Hypotheses based on the contribution of anatomical and molecular factors to specific phenotypic responses are also outlined.

Summary: This study investigates the changes in terricolous bryophytes and lichens in German forests and finds that total species richness remains stable, but some moss species increase while others decrease. Moreover, in coniferous forests and deciduous forests on acid soils, there is an increase in species with high nitrogen demand and shade tolerance, while species adapted to infertile and open forest sites decrease. These changes are likely due to nitrogen deposition and shrub layer closure, indicating nutrient enrichment and increasingly shady conditions.

Summary: Fungal plant pathogens employ proteinaceous and non-proteinaceous effectors, including secondary metabolites (SMs) and small non-coding RNAs (sRNAs), to manipulate the host plant's defense system. While much research has focused on secreted effector proteins, the roles of fungal SMs and sRNAs have been largely overlooked. Fungal SMs are generated during plant colonization, especially in early infection stages, while fungal sRNAs target plant genes involved in resistance and defense responses. Understanding the functions of these effectors can provide insights into the infection process and host genes targeted. This review discusses the roles of fungal SMs and sRNAs in plant-fungal interactions, translocation of sRNA effectors across kingdoms, and the application of cross-kingdom RNA interference in managing plant diseases.
