Current agricultural practices face numerous challenges, including declining soil fertility and heavy reliance on chemical inputs. Rhizosphere microbial metabolites have emerged as promising agents for enhancing crop health yield in a sustainable manner. These metabolites, phytohormones, antibiotics, volatile organic compounds, play critical roles promoting plant growth, boosting resistance to pathogens, improving resilience environmental stresses. This review comprehensively outlines the mechanisms through which rhizosphere influence health, traits, functional components, yield. It also discusses potential applications of secondary biofertilizers highlights challenges associated with their production practical use. Measures overcome these are proposed, alongside an exploration future development fertilizer industry. The findings presented here provide scientific basis utilizing enhance sustainability, offering new strategies management. Integrating could lead increased productivity, improved quality, reduced dependence synthetic inputs, thereby supporting more environmentally friendly resilient system.

Some species of Burkholderia have been studied extensively for their ability to control plant diseases and promote growth. gladioli KRS027 is a strain isolated from the rhizosphere soil healthy in pathogen-infested cotton field Xinjiang, China, which had an inhibitory against various plant-pathogenic fungi. To understand its biocontrol mechanism, we assembled high-quality genome using PacBio-HiFiReads. The contained two circular DNA chromosomes one plasmid, Chr1 4,187,756 bp with 67.95% GC content, Chr2 3,892,275 68.56% plasmid comprised 177,327 61.11% content. Moreover, contains 20 secondary metabolite biosynthesis gene clusters involving polyketides (PKS), nonribosomal peptides (NRPS), hybrid NRPS/PKS, terpene. genes involved phytotoxins, such as toxoflavin, rhizotoxin, bongkrekic acid, were not detected. resource will provide molecular basis further research on mechanisms.

Fungal endophytes are well-known for their ability to promote plant growth and hinder fungal diseases, including Fusarium head blight (FHB) caused by graminearum. This study aimed characterize the biocontrol efficacy of strain J4-3 isolated from stem symptomless wheat collected Heilongjiang Province, China. It was identified as Epicoccum layuense using morphological characteristics phylogenetic analysis rDNA internal transcribed spacer (ITS) beta-tubulin (TUB). In a dual culture assay, significantly inhibited mycelial F. graminearum PH-1 other pathogens. addition, coleoptile tests showed that lesion symptoms were reduced in seedlings treated with hyphal fragment suspensions compared controls. Under field conditions, applying spore filtrates conidial on spikes resulted significant FHB. previously before sowing successfully FHB reduction after application at anthesis. More importantly, fragments increases controls under greenhouse conditions. Overall, these findings suggest E. could be promising agent (BCA) against graminearum, causing growth-promoting fungus wheat.

Rice blast disease, caused by the pathogenic fungus Magnaporthe oryzae, is a widespread infection leading to serious crop loss worldwide. In order achieve sustainable agriculture, root-associated bacteria have been applied manage fungal diseases and promote growth. The present study aimed evaluate in vitro growth-promoting ability vivo biocontrol activity against M. oryzae of rice rhizosphere bacterium. Out sixty-eight isolates recovered from blast-infected plants, isolate NRV12 exhibited highest antifungal SH, with an inhibition percentage 72.7±3.44%. By analysis 16S rRNA sequence associated morphology, physiological biochemical tests, strain was identified as Burkholderia vietnamiensis. addition, produced hydrolytic enzymes (amylase, cellulase, protease), indole acetic acid (IAA), nitrogen-fixing potential solubilize phosphate zinc. Innoculation significantly promoted seedling growth 23.3% compared non-bacteria-treated seedlings. Importantly, infected seedlings treated led 40% disease reduction blast. These findings suggest that valuable promising oryzae.

Abstract Biological control has gained increasing attention as a strategy to address biotic and abiotic stresses in crops. In this study, we identified the strain KRS009 Bacillus mojavensis through morphological identification multilocus sequence analysis. exhibited broad‐spectrum antifungal activity against various phytopathogenic fungi by secreting soluble volatile compounds. Additionally, physio‐biochemical traits of were characterized, including its growth‐promoting capabilities active enzymes. Notably, demonstrated capacity for biofilm formation tolerance saline‐alkali conditions. The biological security evaluation confirmed safety both humans plants. Furthermore, was found trigger plant immunity inducing systemic resistance salicylic acid‐ jasmonic acid‐dependent signaling pathways. Greenhouse experiments conducted on cotton plants proved that treatment with effectively protected Verticillium wilt caused dahliae promoted growth under salt stress. These findings highlight potential B. promising biocontrol biofertilizer agent promoting growth, combating fungal diseases mitigating stress
