Root exudates shift how N mineralization and N fixation contribute to the plant-available N supply in low fertility soils

Yuan Liu et al.

Summary: This study investigated the effects of root exudates on microbial-mediated nitrogen transformations in low fertility soils through laboratory incubation. The results showed that different root exudates influenced soil respiration, dissolved organic carbon, and dissolved organic nitrogen concentrations. Analysis of measured pools revealed that the recovery of root exudate carbon was lower in sandy loam soil. Additionally, organic acids had a greater impact on nitrogen mineralization and fixation rates. Root exudate addition also altered soil pH and organic nitrogen concentrations.

Tree species richness differentially affects the chemical composition of leaves, roots and root exudates in four subtropical tree species

Alexander Weinhold et al.

Summary: This study investigated the impact of tree diversity levels on the metabolomes of four subtropical tree species, revealing that the chemical diversity of leaves, roots, and root exudates increases with tree diversity. Different species and tissues showed varying responses to diversity levels, with plot diversity having a stronger effect on metabolome profiles than local diversity. Further controlled experiments are needed to understand the causes and consequences of shifts in plant metabolomes.

Organic acids: versatile stress-response roles in plants

Poonam Panchal et al.

Summary: This article discusses the central role of organic acids (OAs) in cellular metabolism, highlighting their importance in plant stress responses, soil carbon sequestration, and sustainable food production. OAs are versatile in plant stress tolerance and efficient chelating agents, with key functions in combating climate change. The multiple functions of OAs, such as modifying pH and binding metals, are crucial factors in understanding their important roles in plant stress biology.

Organic-C quality as a key driver of microbial nitrogen immobilization in soil: A meta-analysis

Yansheng Cao et al.

Summary: The addition of organic carbon significantly increased microbial nitrogen immobilization in soil, with glucose being more effective than other compounds. The C/N ratio of organic materials did not significantly affect microbial nitrogen immobilization, and the form of inorganic nitrogen also did not have a significant impact on the response of microbial nitrogen immobilization to organic carbon addition. The chemical quality of organic carbon, rather than the C/N ratio, is a critical factor regulating microbial nitrogen immobilization.

Comparing root exudate collection techniques: An improved hybrid method

Alex Williams et al.

Summary: Plant-microbe interactions are crucial for ecosystem functioning and root exudates play a key role in communication between plants and microbes. Hybrid root exudate collection methods offer an ecologically relevant alternative, but a recovery period after root washing is critical to prevent bias. The hybrid method yields exudates that discriminate between species and provide a diverse metabolome for better identification of metabolites.

Assembly Patterns of the Rhizosphere Microbiome Along the Longitudinal Root Axis of Maize (Zea mays L.)

Lioba Rueger et al.

Summary: The assembly of rhizosphere microbiota along maize roots is found to be more complex than expected, with high randomness in beta diversity at root tips and root hair zones. Further up the root, determinstic processes such as competition and predation appear to be more prominent, leading to low variability in beta diversity and regular phylogenetic co-occurrence patterns in bipartite networks between prokaryotes and their protistan predators.

Cendrine Mony et al.

Summary: This study demonstrated that neighbouring plants from different taxonomic families provided different species pools for the focal plant, influenced the AMF communities associated with the focal plant, especially in terms of species richness. The effects were weakly dependent on phylogenetic distance but predicted by functional proximity, with AMF communities enriched and more similar to the neighbouring plants when functionally dissimilar from the focal plant.

Switchgrass Rhizosphere Metabolite Chemistry Driven by Nitrogen Availability

Darian N. Smercina et al.

Summary: The chemical composition of switchgrass root exudates is influenced by nitrogen levels, with higher nitrogen leading to greater total metabolite concentrations. Furthermore, the relative abundance of carbohydrates was higher under high nitrogen conditions, while organic acids were more abundant under low nitrogen conditions. Inoculation treatments also had an impact on the rhizosphere chemical fingerprints, suggesting a complex relationship between switchgrass, nitrogen, and microbial interactions.
