Arbuscular mycorrhizal fungi (AMF) have been shown to play a major role in regulating the accumulation, transport, and toxicity of cadmium (Cd) plant tissues. This review aims highlight current understanding mechanisms by which AMF alleviate Cd plants. accumulation agricultural soils has become an increasing global concern due industrial activities use phosphatic fertilizers. disrupts various physiological processes plants, adversely affecting growth, photosynthesis, oxidative stress responses, secondary metabolism. plants through multiple mechanisms, including reduced transport into roots, improved nutritional status, modulation organic acid protein exudation, enhanced antioxidant capacity, maintenance ion homeostasis. colonization also influences speciation, bioavailability, compartmentalization within The expression metal transporter genes, as well synthesis phytochelatins metallothioneins, are modulated during stress. However, efficacy mitigating depends on several factors, such soil properties, species, taxa, experimental duration. Further knowledge intricate plant–AMF–Cd interactions is crucial for optimizing AMF-assisted phytoremediation strategies developing Cd-tolerant high-yielding crop varieties cultivation contaminated soils.

Nano‐Selenium Elevating Leaf Quality and Growth Via Microbial‐Regulating Nitrogen Availability Under Ammonium and Nitrate Spraying in Tea Plants

Plant Cell & Environment, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 27, 2025

ABSTRACT Nano‐selenium fertilizers can promote plant growth and nitrogen availability. However, little information is available on the effects of nano‐selenium tea leaf quality, soil nutrient availability associated microbe‐driven mechanisms. This study examined quality cycling in 20‐year‐old plantations when leaves were sprayed with ammonium or nitrate. Leaf selenium amino acid contents increased ninefold 9%, respectively, “Zhongcha108” “Longjing43.” Rhizosphere bacterial fungal community compositions more sensitive to applications “Longjing43” than “Zhongcha108.” enriched taxa related microbial growth, while cellular maintenance acquisition application decreased copy number AOA AOB genes, nosZ nirK genes by 59%, 53%, 37% 46% under ammonium, 77%, 43%, 38% 65%, nitrate spraying, expression these spraying. It concluded that a increases this effect ecological functioning largely depends cultivar‐specific composition function.

Effects of Arbuscular Mycorrhizal Fungi on the Growth and Nutrient Uptake in Wheat Under Low Potassium Stress

Plants, Journal Year: 2025, Volume and Issue: 14(9), P. 1288 - 1288

Published: April 24, 2025

Potassium (K) plays important roles in plant growth and development processes, while low K (LK) stress inhibits by altering reactive oxygen species accumulation. Arbuscular mycorrhizal fungi (AMF) promote nutrient absorption transport plants. However, the of AMF affecting nutrition are less well studied than those other nutrients, especially wheat. In this study, effects on four wheat varieties were evaluated; results showed that inoculation with AMF-Rhizophagus intraradices significantly increased colonization, fresh dry weights, ascorbic acid, glutathione contents, decreasing malondialdehyde contents under both normal LK treatments. It is worth noting several elements more roots shoots, suggesting mainly affect uptake roots. Moreover, expression levels transporter genes higher nitrogen phosphorus genes, combined These indicate improves antioxidant activity regulating gene transport. Therefore, could be used as a sustainable agricultural alternative soils.

Enhancing soil health through balanced fertilization: a pathway to sustainable agriculture and food security

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 16

Published: April 28, 2025

Sustainable soil health management is pivotal for advancing agricultural productivity and ensuring global food security. This review comprehensively evaluates the effects of mineral-organic fertilizer ratios on microbial communities, enzymatic dynamics, functional gene abundance, holistic health. By integrating bioinformatics, enzyme activity assays, metagenomic analyses, we demonstrate that balanced fertilization significantly enhances diversity, community stability, resilience against environmental stressors. Specifically, synergistic application mineral organic fertilizers elevates β-glucosidase urease activities, accelerating matter decomposition nutrient cycling while modulating taxa critical transformation pathogen suppression. Notably, replacing 20-40% with alternatives mitigates risks such as greenhouse gas emissions leaching sustaining crop yields. dual approach improves structure, boosts water retention capacity, increases biomass by 20-30%, fostering long-term fertility. Field trials reveal yield 25-40% in crops like rice maize under combined fertilization, alongside enhanced carbon (110.6%) nitrogen content (59.2%). The findings underscore necessity adopting region-specific, strategies to optimize ecological sustainability productivity. Future research should prioritize refining frameworks through interdisciplinary approaches, addressing soil-crop-climate interactions, scaling these practices diverse agroecosystems. aligning policies principles, stakeholders can safeguard health-a cornerstone human wellbeing-while securing resilient systems future generations.

Published: May 27, 2025

Zizania latifolia (Jiaobai) is an economically important aquatic crop characterized by unique gall formation through interaction with the smut fungus Ustilago esculenta. Understanding factors influencing this crucial for cultivation. This study investigates non-target effects of fungicide Fenaminosulf (FM) on Z. latifolia’s growth, physiology, and underlying molecular pathways. We demonstrate that FM exerts striking concentration-dependent effects, revealing its potential as a modulator plant development symbiosis. Physiological measurements showed moderate concentration (1.25 g/L) promoted key vegetative growth parameters, including height leaf length, while maintaining chlorophyll content, suggesting bio-stimulant effect. In contrast, higher concentrations (2.5 g/L 5 inhibited but significantly enhanced formation, particularly at 2.5 g/L, indicating can redirect resources or alter susceptibility to favor fungal under specific conditions. Transcriptomic analysis provided mechanistic insights, extensive gene expression reprogramming, especially high treatment (5 g/L). Key pathways related plant-pathogen interaction, phenylpropanoid biosynthesis, hormone signal transduction were modulated. Notably, suppressed immune-related genes, Xa21 PBL19, potentially reducing resistance facilitating formation. Hormone signaling revealed inhibition auxin, cytokinin, brassinosteroid, jasmonic acid metabolism, comprehensive recalibration developmental processes.
