Опубликована: Дек. 5, 2023

This review covers the literature data on plant growth-promoting bacteria in soil, which can fix atmospheric nitrogen, solubilize phosphates, produce and secrete siderophores, may exhibit several different behaviors simultaneously. We discuss perspectives for creating bacterial consortia introducing them into soil to increase crop productivity agrosystems. The application of rhizosphere bacteria-which are capable fixing solubilizing organic inorganic secreting as well their consortia-has been demonstrated meet objectives sustainable agriculture, such increasing fertility yields. combining with mineral fertilizers is a crucial trend that allows reduction fertilizer use beneficial production.

The role of endophytes to combat abiotic stress in plants

Plant Stress, Год журнала: 2024, Номер 12, С. 100435 - 100435

Climatic changes and global warming produce abiotic stressors that affect plant development productivity. Abiotic stressors, such as drought, salt, cold, heat, significantly impair agricultural crop yields. The endophyte is a type of endosymbiont, usually bacteria or fungus lives inside cells doesn't cause disease in the host plant. This review scrutinizes integral contribution endophytes to augmenting stress tolerance plants. core analysis investigates regulatory role mechanism pivotal physiological aspects plants under conditions. includes their involvement managing water uptake maintaining balance during drought salinity stress, regulating osmotic scavenging reactive oxygen species (ROS). Additionally, explores outlines diverse strategies for inoculating applying enhance Endophytes secondary active compounds defend from diseases extracellular enzymes help colonize hosts. Microbial may thrive poor soil conditions through phytohormone production hazardous chemical degradation. use many processes survive nutritional deficiency, heavy metal temperature. These findings suggest rhizobacteria cope with stress. Still, more research needed understand mechanisms side effects maximize sustainable climate-smart agriculture.

Serratia spp. as plant growth-promoting bacteria alleviating salinity, drought, and nutrient imbalance stresses

Frontiers in Microbiology, Год журнала: 2024, Номер 15

Опубликована: Март 18, 2024

In agricultural environments, plants are often exposed to abiotic stresses including temperature extremes, salt stress, drought, and heavy metal soil contamination, which leads significant economic losses worldwide. Especially stress drought pose serious challenges since they induce ionic toxicity, osmotic oxidative in plants. A potential solution can be the application of bacteria Serratia spp. known promote plant growth under normal conditions Thus mini-review aims summarize current knowledge on promotion by (under salinity nutrient deficit) highlight areas for development field. So far, it has been proven that strains exhibit a variety traits contributing enhanced tolerance, such as phytohormone production, ACC deaminase activity, nitrogen fixation, P Zn solubilization, antioxidant properties improvement, modulation gene expression. Nevertheless, further research is needed, especially two subjects: elucidating its mechanisms action at molecular level effects indigenous microbiota and, particularly, rhizosphere. both cases, advisable use omics techniques gain in-depth insights into issues. Additionally, some may phytopathogens, therefore studies rule out this possibility recommended prior field trials. It believed improving said stimulate will increase from genus serve an eco-friendly biofertilizer sustainable agriculture more often.

Enhanced efficiency fertilizers: Overview of production methods, materials used, nutrients release mechanisms, benefits and considerations

Environmental Pollution and Management, Год журнала: 2024, Номер 1, С. 32 - 48

The application of fertilizers is necessary for continuous replenishment plants nutrients, sustaining the productivity soils. Inorganic are very simple, chemically defined, water soluble, and easily absorbed immediate reproducible responses in plants. In excess needs however, they do not only scorch plants, but also lost to atmosphere as greenhouse gases. Prolonged usage leads reduced soil quality, acidification (accompanied by dissolution carbonate gases emission), contamination underground water. Increasing nutrients use efficiency ameliorates these problems ensuring a better synchronization availability with uptake. Without increasing frequency fertilization associated labor cost (encountered split-fertilization), enhanced (EEFs) gradually make available over long period time, that met after single seasonal fertilization, without compromising integrity soil. EEFs benefits environment retarding availability; some materials used formulation impact beneficial qualities (e.g., improved structure, erosion) production EEFs, such coated fertilizers, depending on nature coat, completely environmentally friendly; effects certain due variability between fertilizer batches conditions. These challenges development different potential solutions, their formulation, addition advantages discussed. information contained herein expected arouse more research sustainable assist farmers selecting best kind condition, crops production, while health.

Plant growth promotion via priming with volatile organic compounds emitted from Bacillus vallismortis strain EXTN-1

Frontiers in Microbiology, Год журнала: 2025, Номер 15

Опубликована: Янв. 10, 2025

Volatile organic compounds (VOCs) produced by potential plant growth-promoting rhizobacteria (PGPR) play an important role in interactions. However, the mechanisms underlying this phenomenon are not well understood. Our findings show that influence of VOCs from PGPR strain Bacillus vallismortis (EXTN-1) on tobacco growth is dependent culture media used. The released sugar-rich such as potato dextrose agar (PDA) and King's B (KB) were highly effective. exposure to nutrient (NA), tryptic soy (TSA), Luria-Bertani (LB) resulted chlorosis stunted growth. This effect was caused discharge a large amount ammonia altered pH media. Seedlings exposed for 10 days exhibited improved even after eliminated under greenhouse conditions. Priming seeds with 24 48 h induced higher than untreated control, better compared treatment. Chemical characterization emitted EXTN-1 different using solid-phase microextraction (SPME) coupled gas chromatography-mass spectrometry (GC-MS) showed presence 2,3-butanedione monoxime all spectra. 1-butanol prominent peak VOC grown KB NA, while acetoin highest PDA, followed KB.
