The utilization of chemical pesticides recovers 30%-40% food losses. However, their application has also triggered a series problems, including safety, environmental pollution, pesticide resistance, and incidents poisoning. Consequently, green are increasingly seen as viable alternatives to counterparts. Among these, Plant Growth-Promoting Rhizobacteria (PGPR), which found within plant rhizosphere, stand out for capacity stimulate growth. Recently, we isolated strain, BN, with broad-spectrum antimicrobial activity from the rhizosphere Lilium brownii. Identification revealed that this strain belongs species Bacillus velezensis exhibits significant inhibitory effects against various fungal pathogens. complete genome sequence B. BN consists circular chromosome length 3,929,791 bp, includes 3,747 protein-coding genes, 81 small RNAs, 27 rRNAs, 86 tRNAs. Genomic analysis 29% genes directly involved in growth, while 70% indirectly involved. In addition, 12 putative biosynthetic gene clusters were identified, responsible synthesis secondary metabolites, such non-ribosomal peptides, lanthipeptides, polyketides, siderophores, terpenes. These findings provide scientific basis development efficient agents construction biopesticide production platforms chassis cells.

Abstract Background The utilization of beneficial (Rhizo) bacteria, as an alternative to traditional fertilizers, has emerged eco-friendly strategy for ameliorating sustainable agricultural production. This approach aims reduce the use agrochemicals and minimize environmental pollution. Scope review provides updated insight into ecological impact plant growth-promoting rhizobacteria (PGPR), focusing on resident microbiome its potential transferability next generation plants. Conclusion In this context, PGPR are assumed alter rhizosphere by outcompeting existing taxa through nutrient deprivation, acidification environment, metabolites production, consequently, increasing copiotrophic taxa. Such modifications can maximize interactions plant-PGPR bioavailability nutrients handling diverse signaling pathways. effects within PGPR-root system adjust composition root exudates influence release bioactive molecules root, especially under stress conditions, which act signals reactivate recruit microbes in endosphere favor changes structure occur gradually over time, even if survival rate soil their re-colonization efficiency inside tissue limited. aforementioned have increase chances progeny plants growing same conditions. Establishing a comprehensive robust knowledge framework that addresses all these issues is critical significantly advancing field microbe-plant developing reliable applications PGPR.

Bacillus cereus G2 Facilitates N Cycle in Soil, Further Improves N Uptake and Assimilation, and Accelerates Proline and Glycine Betaine Metabolisms of Glycyrrhiza uralensis Subjected to Salt Stress

Journal of Agricultural and Food Chemistry, Год журнала: 2023, Номер 71(42), С. 15485 - 15496

Опубликована: Окт. 13, 2023

Soil salinity is a severe abiotic stress that reduces crop productivity. Recently, there has been growing interest in the application of microbes, mainly plant-growth-promoting bacteria (PGPB), as inoculants for saline land restoration and plant tolerance. Herein, effects endophyte G2 on regulating soil N cycle, uptake assimilate pathways, proline glycine betaine biosynthesis, catabolic pathways were investigated Glycyrrhiza uralensis exposed to salinity. The results indicated improved efficiency absorption assimilation plants by facilitating cycling. Then, promoted synthesis substrates accelerated its rate, which increased relative water content reduced electrolyte leakage, eventually protecting membrane system caused salt G. uralensis. These findings will provide new idea from systems environment.

This study aimed to investigate the mechanisms by which dark septate endophytes (DSE) regulate salt tolerance and accumulation of bioactive constituents in licorice. First, stress resynthesis with plant effect isolated DSE from wild licorice were tested. Second, performance inoculated DSE, had best salt-tolerant growth-promoting effects, was examined under stress. All showed promoted growth, withCurvularia lunata D43 being most effective. Under stress, C. could promote increase antioxidant enzyme activities, enhance glycyrrhizic acid accumulation, improve key activities synthesis pathway, induce expression gene The structural equation model demonstrated that alleviate negative effects through direct indirect pathways. Variations expression, constituent concentration can be attributed DSE. These results contribute revealing value for cultivating medicinal plants saline soils.

Abstract Boosting plant immunity by priming agents can lower agrochemical dependency in production. Levan and levan‐derived oligosaccharides (LOS) act as against biotic stress several crops. Additionally, beneficial microbes promote growth protect fungal diseases. This study assessed possible synergistic effects caused levan, LOS five levan‐ LOS‐metabolizing Bacillaceae ( Bacillus Priestia ) strains tomato wheat. Leaf seed defense assays were conducted non‐soil (semi‐sterile substrate) soil‐based systems, focusing on tomato‐ Botrytis cinerea wheat‐ Magnaporthe oryzae Triticum (MoT) pathosystems. In the system, with (especially velezensis GA1), or their combination significantly promoted protection B. . While no stimulatory observed for wheat, disease protective also wheat‐MoT pathosystem. When grown soil subjected to leaf priming, plants co‐applied levan bacterial showed increased resistance compared treated single strains, these some cases. For soil, more tolerance a non‐fertilized fertilized suggesting that potential prebiotic of are prominent poor soils. The using combinations Bacilliaceae sustainable agriculture is discussed.
