Microbial Communities in Continuous Panax notoginseng Cropping Soil

Agronomy, Journal Year: 2025, Volume and Issue: 15(2), P. 486 - 486

Published: Feb. 18, 2025

Panax notoginseng is a prominent traditional Chinese medicinal herb, yet its yield and quality are significantly constrained by continuous cropping obstacles, primarily stemming from soil-related issues. This study analyzed soils subjected to various degrees of P. cultivation, without planting, natural forest floor soil planting. The objective was investigate variations in microbial communities, physicochemical properties, enzyme activities across different conditions. Macro-genome sequencing employed reveal shifts key factors influencing rhizosphere communities. Notably, the exhibited highest levels organic matter, carbon, total nitrogen, available potassium. Furthermore, showed pH, phosphorus, electrical conductivity, catalase, urease, acid phosphatase, sucrase, FDA hydrolase decreased after cropping, but increased again five years fallowing. Microbial analysis revealed that Bacteroidetes, Firmicutes, Chloroflexi dominated whereas Proteobacteria, Actinobacteria, Acidobacteria were predominant phyla soils. Continuous led an increase Acidobacteria, Gemmatimonadetes, Chloroflexi, while fallowing reduced Actinobacteria. Gemmatimonades almost exclusively present Overall, planting altered nutrients composition. Key communities included nitrate potassium, conductivity. suggests attention should be paid scientific rational fertilization practices mitigate effects cropping. Additionally, fallow period more than recommended. proper application probiotic fertilizers also advised. Finally, cultivating under conditions recommended as viable method.

Abstract Plant pathogens cause plant diseases that significantly decrease crop yields, posing a serious threat to global food security. While disease resistance has traditionally been understood as the trait determined by innate immune system and pathogen virulence system, recent research underscores pivotal role of microbiome in resistance. Plant-associated microbiomes confer protection against through direct inhibition, resource competition, activation responses. Agricultural practices such rotation, intercropping, disease-resistant breeding, biocontrol, organic farming modulate microbiomes, thereby influencing This review synthesizes latest advancements understanding intricate interactions among plants, pathogens, microbiomes. We emphasize need for in-depth mechanistic studies linking agricultural dynamics propose future directions leverage sustainable agriculture.

Harnessing plant–microbe interactions: strategies for enhancing resilience and nutrient acquisition for sustainable agriculture

Frontiers in Plant Science, Journal Year: 2025, Volume and Issue: 16

Published: April 15, 2025

The rhizosphere, a biologically active zone where plant roots interface with soil, plays crucial role in enhancing health, resilience, and stress tolerance. As key component achieving Sustainable Development Goal 2, the rhizosphere is increasingly recognized for its potential to promote sustainable agricultural productivity. Engineering microbiome emerging as an innovative strategy foster growth, improve adaptation, restore soil health while mitigating detrimental effects of conventional farming practices. This review synthesizes recent advancements omics technologies, sequencing tools, synthetic microbial communities (SynComs), which have provided insights into complex interactions between plants microbes. We examine root exudates, composed organic acids, amino sugars, secondary metabolites, biochemical cues that shape beneficial rhizosphere. further explores how advanced techniques like metagenomics metabolomics are employed elucidate mechanisms by exudates influence health. Tailored SynComs shown promising resilience against both abiotic stresses (e.g., drought salinity) biotic challenges pathogens pests). Integration these microbiomes optimized exudate profiles has been nutrient cycling, suppress diseases, alleviate environmental stresses, thus contributing more By leveraging multi-disciplinary approaches optimizing profiles, ecological engineering plant-microbiome presents pathway boosting crop approach also aids managing soil-borne reducing chemical input dependency, aligning Goals aimed at global food security sustainability. ongoing research offers significant promise ensuring long-term productivity preserving future generations.
