With climate change, the frequency of regions experiencing water scarcity is increasing annually, posing a significant challenge to crop yield. Barley, staple consumed and cultivated globally, particularly susceptible detrimental effects drought stress, leading reduced yield production. Water adversely affects multiple aspects barley growth, including seed germination, biomass production, shoot root characteristics, osmotic status, photosynthesis, induces oxidative resulting in considerable losses grain its components. In this context, present review aims underscore importance selecting drought-tolerant genotypes utilizing bio-inoculants constructed from beneficial microorganisms as an agroecological approach enhance growth production resilience under varying environmental conditions. Selecting with robust physiological agronomic tolerance can mitigate diverse Plant Growth Promoting Rhizobacteria (PGPR) play crucial role promoting plant through nutrient solubilization, nitrogen fixation, phytohormone exopolysaccharide secretion, enzyme activity enhancement, many other mechanisms. Applying containing PGPR, improves barley's thereby minimizing caused by scarcity.

Soils are a hotspot for the emergence and spread of antibiotic resistance. The effects agrochemical treatments on bacterial community agricultural soils content antibiotic-resistance genes (ARGs) were studied. Treatments included following: control, mineral fertilizers (NPKs), pesticides, combined treatment under soya (Glycine max), sunflower (Helianthus annuus L.), wheat (Triticum aestivum). Bacterial taxonomic composition was studied using 16S rRNA gene sequencing. 10 ARGs 3 integron (intI1, intI2, intI3) determined quantitative real-time PCR. results showed that had little effect diversity soil community. most significant factors determining differences in microbial sampling time physico-chemical parameters. A role ARG distribution demonstrated. Representatives Pseudomonas, Bacillus, Sphingomonas, Arthrobacter genera, Nocardioidaceae Micrococcaceae families likely hosts. presence all three classes detected, numerous being intI3. This work provides important information transfer, findings may be useful sustainable safe development.

Enhancing Agricultural Sustainability Through Rhizomicrobiome: A Review

Journal of Basic Microbiology, Год журнала: 2024, Номер 64(11)

Опубликована: Июнь 20, 2024

Sustainable agriculture represents the responsible utilization of natural resources while safeguarding well-being environment. It encompasses objectives preserving environment, fostering economic growth, and promoting socioeconomic equality. To achieve sustainable development for humanity, it is imperative to prioritize agriculture. One significant approach achieving this transition extensive microbes, which play a crucial role due genetic reliance plants on beneficial functions provided by symbiotic microbes. This review focuses significance rhizospheric microbial communities, also known as rhizomicrobiome (RM). complex community microorganisms that live in rhizosphere influence plant's growth health. provides its host plant with various benefits related including biocontrol, biofertilization, phytostimulation, rhizoremediation, stress resistance, other advantageous properties. Yet, mechanisms RM contributes remain largely unknown. Investigating population presents opportunity advance toward Hence, study aims provide an overview diversity applications practices. Lately, there has been growing momentum areas rhizobiome research application includes engineering, synthetic microbiome application, agent-based modeling rhizobiome, metagenomic studies. So, developing bioformulations these support could serve promising solution future strategies aimed at new green revolution.

Immunomodulating melatonin-decorated silica nanoparticles suppress bacterial wilt (Ralstonia solanacearum) in tomato (Solanum lycopersicum L.) through fine-tuning of oxidative signaling and rhizosphere bacterial community

Journal of Nanobiotechnology, Год журнала: 2024, Номер 22(1)

Опубликована: Окт. 12, 2024

Tomato (Solanum lycopersicum L.) production is severely threatened by bacterial wilt, caused the phytopathogenic bacterium Ralstonia solanacearum. Recently, nano-enabled strategies have shown tremendous potential in crop disease management. This study investigates efficacy of biogenic nanoformulations (BNFs), comprising silica nanoparticles (SiNPs) and melatonin (MT), controlling wilt tomato. SiNPs were synthesized using Zizania latifolia leaves extract. Further, MT containing BNFs through one-pot approach. Nanomaterials characterized standard characterization techniques. Greenhouse assays conducted to assess impact on tomato plant immunity resistance wilt. The exhibited a spherical morphology, with particle sizes ranging from 13.02 nm 22.33 for 17.63 21.79 BNFs, indicating relatively uniform size distribution consistent shape across both materials. experiments revealed that soil application outperformed SiNPs, significantly enhancing reducing incidence 78.29% plants maintaining oxidative stress homeostasis via increasing activities antioxidant enzymes such as superoxide dismutase (31.81%), peroxidase (32.9%), catalase (32.65%), ascorbate (47.37%) compared untreated infected plants. Additionally, induced salicylic acid activating defense-related genes (e.g., SlPAL1, SlICS1, SlNPR1, SlEDS, SlPD4, SlSARD1) involved phytohormones signaling High-throughput 16 S rRNA sequencing promoted growth beneficial rhizosphere bacteria (Gemmatimonadaceae, Ramlibacter, Microscillaceae, Anaerolineaceae, Chloroplast Phormidium) healthy diseased plants, while suppressing R. solanacearum abundance Overall, these findings suggest offer more promising sustainable approach managing
