Summary: This study examined the impact of wastewater treatment plant (WWTP) discharges on nutrient concentrations in receiving rivers in Sao Paulo state, Brazil. The results showed that WWTP discharges significantly increased nutrient concentrations and loads, with limited net nutrient uptake along the river reaches. These findings suggest that WWTPs with limited nutrient removal have considerable effects on water chemistry and nutrient cycling, potentially impairing downstream ecosystems.

Summary: This study investigated the responses of the fungal community and the host tree to fluctuations in nitrogen availability. The results showed that the fungi displayed resistance to increased nitrogen levels, while the tree dynamically metabolized the supplied nitrogen sources.

Summary: It was found that there is substantial genetic variation in maize for multiple ion-uptake rates and specific nutrient uptake rates are positively correlated with specific root respiration, indicating shared mechanisms governing uptake. RNA-seq analysis of maize lines with high and low specific uptake rates identified key regulatory components involved in nutrient uptake. The high-throughput multiple ion-uptake kinetics pipeline will further understanding of nutrient uptake and help identify breeding targets for crops with more efficient nutrient acquisition.

Summary: The study found that moderate increases in CO2 concentration and AMF colonization can promote wheat growth and soil fertility. However, nighttime eCO2 environments may reduce the beneficial effects of AMF on plants. Therefore, integrating the benefits of AMF is crucial for managing the long-term consequences of future CO2 rising on global cropping systems.

Summary: This study investigated the effects of overexpression of the ammonium transporter LbAMT3-1 on nutrient uptake and plant productivity. The results showed that LbAMT3-1 overexpression can enhance the absorption of nutrients and increase the abundance of mycorrhizal in plants. This study provides a potential strategy for using LbAMT3-1 in breeding programs to improve nutrient uptake in plants.

Summary: The excessive use of chemicals in agroecosystems by farmers has negative effects on soil quality, soil ecology, and human health. This study focused on utilizing a Bacillus safensis strain STJP and mycorrhiza Glomus fasciculatum ABTEC to develop a whey-based bioformulation for enhancing the growth, nutrient uptake, soil properties, stevioside content, and steviol glycosides (SGs) biosynthesis in Stevia rebaudiana. The combined treatment of the bioformulation and mycorrhiza showed significant improvements in the growth parameters, chlorophyll content, protein content, flavonoid content, carbohydrate content, antioxidant activity, stevioside content, and mineral uptake in the plants. The results suggest that the application of the bioformulation and mycorrhiza provides an eco-friendly and sustainable solution for improving the yield and quality of Stevia rebaudiana.

Summary: The hydrography of the Arctic Seas is changing due to climate change, impacting nutrient dynamics and primary production. The study shows that physical processes control nutrient dynamics in the Fram Strait, with Atlantic Waters experiencing lower nitrogen limitation compared to Polar Surface Water. The loss of winter sea ice and continued atmospheric warming may hinder deep winter mixing and limit future primary production in the Arctic.

Summary: This study analyzed the effects of arbuscular mycorrhizal (AM) fungi and earthworms on plant growth and nitrogen content in soil. The introduction of earthworms improved the effect of AM fungi on chlorophyll and plant growth. The introduction of earthworms increased root and soil nitrogen content, while the introduction of AM fungi increased nitrogen content in leaves, roots, easily extractable glomalin-related soil protein (GRSP), and soil. AM fungi increased the contribution of nitrogen in GRSP to soil total nitrogen, and the introduction of earthworms further accelerated this effect.

Summary: Shifts in tree species and their mycorrhizal associations driven by global change have significant impacts on biogeochemical cycles. In this study, we proposed and tested a framework of mycorrhizal-associated nutrient economy (MANE) in two tropical rainforests through nutrient addition experiments. We found that distinct MANE frameworks were applicable for different types of rainforests, with organic and inorganic forms of nutrient cycling in ECM-dominated and AM-dominated rainforests, respectively. Moreover, the effects of mycorrhizal types on soil P cycling were stronger than those on C and N cycling. The findings highlight the crucial role of mycorrhizal types in regulating biogeochemical processes and provide important insights for understanding the ecological consequences of global changes.

Summary: The release of carboxylates by roots increases manganese phytoavailability and uptake by plants. The success of Lambers and colleagues' approach depends on plants being able to increase root manganese uptake and leaf manganese concentration when releasing carboxylates, as well as tolerating the resulting higher tissue manganese concentrations.
