Wetlands, being a considerable source of atmospheric methane (CH4), are intricately linked to global climate change. Alpine swamp meadows, being roughly half of the Qinghai-Tibet Plateau's natural wetlands, were deemed to be one of the most crucial ecological systems. Important functional microbes, methanogens, are essential to the methane production process. However, the temperature-induced effects on methanogenic communities and the primary pathways of CH4 generation in alpine swamp meadows at diverse water levels in permafrost wetlands remain unexplained. We explored how temperature changes affected methane production in soil and the associated methanogenic community shifts, analyzing samples of alpine swamp meadow soil from the Qinghai-Tibet Plateau, varying in water content, through anaerobic incubations at controlled temperatures of 5°C, 15°C, and 25°C. cachexia mediators Elevated incubation temperatures directly influenced the escalation of CH4 content, specifically exhibiting a five- to ten-fold increase at the high-water-level sites (GHM1 and GHM2) compared to the low-water-level site (GHM3). Incubation temperature fluctuations had a negligible influence on the structure of the methanogenic community at the high-water-level sites (GHM1 and GHM2). In terms of methanogen groups, Methanotrichaceae (3244-6546%), Methanobacteriaceae (1930-5886%), and Methanosarcinaceae (322-2124%) were dominant; a considerable positive correlation (p < 0.001) was found between the abundance of Methanotrichaceae and Methanosarcinaceae and the amount of CH4 generated. Within the low water level site (GHM3), a noticeable shift in the methanogenic community structure took place at a temperature of 25 degrees Celsius. The methanogen group Methanobacteriaceae (5965-7733%) reigned supreme at 5°C and 15°C. In stark contrast, Methanosarcinaceae (6929%) was the dominant group at 25°C, and a significant positive relationship (p < 0.05) was noted between its abundance and methane production. During the warming process in permafrost wetlands, these findings collectively highlight how different water levels affect the structure of methanogenic communities and the production of CH4.

Plant roots exude metabolites, including substances like ginsenosides from ginseng roots, into the soil. Furthermore, there is a lack of comprehensive information on the chemical and microbial implications of ginseng root exudates in the soil environment. This research sought to determine how increasing levels of ginsenosides affected the chemical and microbial makeup of the soil. 0.01 mg/L, 1 mg/L, and 10 mg/L ginsenosides were externally applied, and subsequent soil chemical properties and microbial characteristics were evaluated using chemical analysis and high-throughput sequencing. Ginsenosides' application resulted in a marked alteration of soil enzyme activities, with a concomitant significant reduction in the SOM-driven physicochemical characteristics of the soil. This change subsequently affected the structure and composition of the soil microbial community. The application of 10 mg/L ginsenosides demonstrably increased the relative prevalence of fungal pathogens like Fusarium, Gibberella, and Neocosmospora. Ginseng root exudates' ginsenosides, as revealed by these findings, might be associated with increased soil degradation during cultivation, thus driving future research to explore the mechanisms of interaction between these compounds and soil microbial communities.
