Published: April 21, 2023

Rhizosheric bacteria with several abilities related to plant growth and health have been denominated Plant Growth-Promoting Rhizobacteria (PGPR). PGPR promote through modes of action, be it directly or indirectly. The benefits provided by these can include increased nutrient availability, phytohormone production, shoot root development, protection against phytopathogens, reduced diseases. Additionally, help plants withstand abiotic stresses such as salinity drought produce enzymes that detoxify from heavy metals. become an important strategy in sustainable agriculture due the possibility reducing synthetic fertilizers pesticides, promoting health, enhancing soil quality. There are many studies literature. However, this review highlights used for production a practical way, making possible reduce use phosphorus nitrogen fungicides, improve uptake. This addresses topics unconventional fertilizers, seed microbiome rhizospheric colonization, microorganisms, fixation chemical solubilizing mineralizing, siderophore fungicides pesticides agriculture.

Fungi That Promote Plant Growth in the Rhizosphere Boost Crop Growth

Journal of Fungi, Journal Year: 2023, Volume and Issue: 9(2), P. 239 - 239

Published: Feb. 10, 2023

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.

The viable community of microorganisms in the rhizosphere significantly impacts physiological development and vitality plants. assembly functional capacity microbiome are greatly influenced by various factors within rhizosphere. primary host plant genotype, developmental stage status, soil properties, resident microbiota. These drive composition, dynamics, activity microbiome. This review addresses intricate interplay between these how it facilitates recruitment specific microbes to support growth resilience under stress. also explores current methods for engineering manipulating microbiome, including plant-mediated manipulation, soil-related methods, microbe-mediated methods. Advanced techniques harness plant's ability recruit useful promising use rhizo-microbiome transplantation highlighted. goal this is provide valuable insights into knowledge, which will facilitate cutting-edge strategies enhanced stress tolerance. article indicates avenues future research field.

Decrypting the multi-functional biological activators and inducers of defense responses against biotic stresses in plants

Heliyon, Journal Year: 2023, Volume and Issue: 9(3), P. e13825 - e13825

Published: Feb. 18, 2023

Plant diseases are still the main problem for reduction in crop yield and a threat to global food security. Additionally, excessive usage of chemical inputs such as pesticides fungicides control plant have created another serious human environmental health. In view this, application growth-promoting rhizobacteria (PGPR) controlling disease incidences has been identified an eco-friendly approach coping with security issue. this review, we different ways by which PGPRs capable reducing phytopathogenic infestations enhancing yield. PGPR suppresses diseases, both directly indirectly, mediated microbial metabolites signaling components. Microbial synthesized anti-pathogenic siderophores, antibiotics, lytic enzymes, hydrogen cyanide, several others act on phytopathogens. The indirect mechanisms infestation caused stimulation immune responses known initiation systemic resistance (ISR) is triggering elicited through pathogen-associated molecular patterns (PAMPs). ISR triggered infected region leads development acquired (SAR) throughout making resistant wide range pathogens. A number including Pseudomonas Bacillus genera proven their ability stimulate ISR. However, there some challenges large-scale acceptance pest management. Further, discuss newly formulated inoculants possessing activities suppression holistic sustaining health productivity.

Synergistic impact of nanomaterials and plant probiotics in agriculture: A tale of two-way strategy for long-term sustainability

Frontiers in Microbiology, Journal Year: 2023, Volume and Issue: 14

Published: May 3, 2023

Modern agriculture is primarily focused on the massive production of cereals and other food-based crops in a sustainable manner order to fulfill food demands an ever-increasing global population. However, intensive agricultural practices, rampant use agrochemicals, environmental factors result soil fertility degradation, pollution, disruption biodiversity, pest resistance, decline crop yields. Thus, experts are shifting their focus eco-friendly safer methods fertilization ensure sustainability. Indeed, importance plant growth-promoting microorganisms, also determined as “plant probiotics (PPs),” has gained widespread recognition, usage biofertilizers being actively promoted means mitigating harmful effects agrochemicals. As bio-elicitors, PPs promote growth colonize or tissues when administered soil, seeds, surface used alternative avoid heavy In past few years, nanotechnology brought revolution due application various nanomaterials (NMs) nano-based fertilizers increase productivity. Given beneficial properties NMs, these two can be tandem maximize benefits. combinations NMs PPs, synergistic use, its infancy but exhibited better crop-modulating terms improvement productivity, mitigation stress (drought, salinity, etc.), restoration fertility, strengthening bioeconomy. addition, proper assessment necessary before application, dose should applicable without showing any toxic impact environment microbial communities. The combo encapsulated within suitable carrier, this method aids controlled targeted delivery entrapped components increases shelf life PPs. review highlights functional annotation combined manner.
