The fungi species dwelling in the rhizosphere of crop plants, revealing functions that endeavor sustainability are commonly referred to as ‘plant-growth-promoting fungi’ (PGPF). They biotic inducers provide benefits and carry out important agricultural sustainability. problem encountered system nowadays is how meet population demand based on yield protection without putting environment human animal health at risk production. PGPF including Trichoderma spp., Gliocladium virens, Penicillium digitatum, Aspergillus flavus, Actinomucor elegans, Podospora bulbillosa, Arbuscular mycorrhizal fungi, etc., have proven their ecofriendly nature ameliorate production crops by improving growth shoots roots germination seeds, chlorophyll for photosynthesis, abundant crops. PGPF’s potential mode action follows: mineralization major minor elements required support plants’ productivity. In addition, produce phytohormones, induced resistance, defense-related enzymes inhibit or eradicate invasion pathogenic microbes, other words, help plants while encountering stress. This review portrays an effective bioagent facilitate promote production, plant growth, resistance disease invasion, various abiotic stresses.

Microbial Consortia for Plant Protection against Diseases: More than the Sum of Its Parts

International Journal of Molecular Sciences, Год журнала: 2023, Номер 24(15), С. 12227 - 12227

Опубликована: Июль 31, 2023

Biological plant protection presents a promising and exciting alternative to chemical methods for safeguarding plants against the increasing threats posed by diseases. This approach revolves around utilization of biological control agents (BCAs) suppress activity significant pathogens. Microbial BCAs have potential effectively manage crop disease development interacting with pathogens or hosts, thereby their resistance. However, current efficacy remains unsatisfactory, creating new research opportunities sustainable cultivation management. In this context, microbial consortia, comprising multiple microorganisms diverse mechanisms action, hold promise in terms augmenting magnitude stability overall antipathogen effect. Despite scientific efforts identify construct consortia that can aid vital crops, only limited number consortia-based biocontrol formulations are currently available. Therefore, article aims present complex analysis status explore future directions technological advancements.

Response of bacterial community metabolites to bacterial wilt caused by Ralstonia solanacearum: a multi-omics analysis

Frontiers in Plant Science, Год журнала: 2024, Номер 14

The soil microbial community plays a critical role in promoting robust plant growth and serves as an effective defence mechanism against root pathogens. Current research has focused on unravelling the compositions functions of diverse taxa rhizospheres invaded by Ralstonia solanacearum , however, specific mechanisms which key groups with distinct exert their effects remain unclear. In this study, we employed combination amplicon sequencing metabolomics analysis to investigate principal metabolic rhizosphere soil. Compared healthy tobacco samples, bacterial diversity co-occurrence network diseased were significantly reduced. Notably, certain genera, including Gaiella Rhodoplanes MND1 ( Nitrosomonadaceae ), found be more abundant plants than that plants. Eight environmental factors, exchangeable magnesium, available phosphorus, pH, crucial factors influencing composition community. displayed negative correlations cation exchange flux, but showed positive correlation iron. Furthermore, metabolomic revealed pathways related synthesis various antibacterial compounds enriched group. results indicate genera Polycyclovorans Lysobacter Pseudomonas Nitrosospira may participate compounds. Collectively, our findings contribute in-depth understanding disease resistance within communities provide theoretical foundation for development targeted strategies using beneficial microorganisms suppress occurrence.

Introduction Alternaria solani is a challenging pathogen in the tomato crop globally. Chemical control rapid approach, but emerging fungicide resistance has become severe threat. The present study investigates use of culture filtrates (CFs) three species Trichoderma spp. to this disease. Methods Highly virulent A. strain and fungal strains viz., T. harzianum (Accession No: MW590687), atroviride MW590689) longibrachiatum MW590688) previously isolated by authors were used study. efficacy mitigate early blight disease tested under greenhouse field conditions, experiments conducted different seasons 2020 using variety “doucen”. Results discussion CFs , significantly inhibited vitro mycelial growth (62.5%, 48.73%, 57.82%, respectively, followed 100%). In GC–MS analysis CF volatile compounds harzianic acid (61.86%) linoleic (70.02%) hydroxymethylfurfural (68.08%) abundantly present. Foliar application considerably reduced severity (%) all treatments, (18.03%), (31.91%), (23.33%), infected (86.91%), positively affected plant biomarkers. greenhouse, plants treated with demonstrated higher flavonoids after 6 days inoculation, whereas phenolic increased 2 days. CF-treated antioxidant enzymes, i.e., phenylalanine ammonia-lyase (PAL) peroxidase (POD), 4 days, polyphenol oxidase (PPO) was healthy controls. open both as compared naturally plants, exhibited fruit yield than results conclude that can be potential biocontrol candidate promising alternative for sustainable production.
