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.

ABSTRACT Plant growth‐promoting rhizobacteria (PGPR) are widely recognized for enhancing the absorption of mineral nutrients by crops. While Sphingobium species have been reported as PGPRs, their capacity to improve nitrogen use efficiency (NUE) and underlying regulatory mechanisms not yet fully understood. Here, a strain 41R9, isolated from rhizosphere N‐deficient rapeseed, was found significantly enhance growth performance rapeseed under both low normal N conditions. Genomic analysis revealed that 41R9 closely related yanoikuyae . 15 isotope tracer experiments confirmed inoculation with boosted uptake translocation in roots. Transcriptome profiling demonstrated directly upregulated transporter genes ( NRT2.5 SLAH1/3 ), facilitating efficient acquisition. Furthermore, maintained jasmonic acid (JA) homoeostasis via JAZ‐mediated negative feedback, balancing defense responses root development, thereby improving plant's acquisition Metabolomic vitro assays further displayed strong chemotaxis towards kaempferol, N‐deficiency‐induced exudate, suggesting kaempferol might chemical effector S. recruitment. These findings advance our understanding PGPR‐driven crop NUE highlight potential harnessing PGPRs sustainable agriculture.

Considering the sensitivity of rare microbial taxa to environmental disturbances and their critical roles in ecosystems, it is essential investigate how soil communities (particularly microbes) respond pesticide exposure. In this study, we found that thiazole pesticides significantly reduced severity potato common scab effectively disrupted pathogen's cell membrane integrity. Notably, hierarchical partitioning analysis indicated geocaulosphere constitute key clusters influencing disease incidence. Within bacterial molecular ecological networks, nodes corresponding these generally exhibited higher degrees compared those more abundant taxa. However, exposure number keystone substantially weakened hub status networks. These findings suggest that, although eradicate pathogens, they may also pose a non-negligible potential risk agricultural ecosystems.

Introduction Seagrass-associated microbial communities play a crucial role in the growth and health of seagrasses. However, like seagrass meadows, seagrass-associated are often affected by eutrophication. It remains unclear how eutrophication influences composition function associated with different parts seagrass. Methods We employed prokaryotic 16S rRNA gene high-throughput sequencing combining community structure analysis co-occurrence network to investigate variances compositions, potential functions complexities across sediment, leaves, seawater within eutrophic areas two adjacent meadows on Hainan Island, China. Results Our results indicated that diversity leaves was significantly lower than sediment but higher seawater. Both phyllosphere showed no significant difference between highly less sites each lagoon. more lagoon, while Heavy increased relative abundance microorganisms potentially involved anaerobic metabolic processes, reducing those responsible for beneficial denitrification.
