Climate change, inadequate possessions, and land degradation all pose obstacles to modern agriculture. In the current scenario, agriculture industry is mainly dependent on use of chemical-based pesticides fertilizers that impact soil health crop productivity. Moreover, water scarcity leads farmers in drastically affected regions heavy metal-enriched sources originating from industrial for field crops irrigation. Soil pollutants can be carried into human body via dust water, creating negative effects varying simple symptoms, e.g., nausea diarrhea reaching death critical cases. Thus, clean contaminants, improve fertility agricultural production, alternatives chemical must developed. Therefore, using beneficial microbes found plant-associated microorganisms offers an effective strategy alleviate some these challenges, improving fertility, yield, protecting plants stress conditions.

Abstract Globally, substantial research into endophytic microbes is being conducted to increase agricultural and environmental sustainability. Endophytic such as bacteria, actinomycetes, fungi inhabit ubiquitously within the tissues of all plant species without causing any harm or disease. Endophytes form symbiotic relationships with diverse can regulate numerous host functions, including resistance abiotic biotic stresses, growth development, stimulating immune systems. Moreover, endophytes play a dominant role in nutrient cycling, biodegradation, bioremediation, are widely used many industries. have stronger predisposition for enhancing mineral metal solubility by cells through secretion organic acids low molecular weight metal-specific ligands (such siderophores) that alter soil pH boost binding activity. Finally, synthesize various bioactive compounds high competence promising candidates new drugs, antibiotics, medicines. Bioprospecting novel secondary metabolites has given momentum sustainable agriculture combating stresses. Biotechnological interventions aid played pivotal crop improvement mitigate stress conditions like drought, salinity, xenobiotic compounds, heavy metals. Identification putative genes from conferring tolerance diseases, apart those involved accumulation degradation contaminants, could open avenues development.

Plants are fascinating organisms present in most ecosystems and a model system for studying different facets of ecological interactions on Earth. In the environment, plants constantly encounter multitude abiotic biotic stresses. The zero-avoidance phenomena make them more resilient to such environmental odds. combat stress or pathogenic ingression through complex orchestration intracellular signalling cascades. plant–microbe interaction primarily relies acquired immune response due absence any specialised immunogenic cells adaptive response. generation memory is mainly carried out by T as part humoral animals. Recently, prodigious advancements our understanding epigenetic regulations invoke “plant memory” theory afresh. Current innovations cutting-edge genomic tools have revealed stress-associated alterations strengthened idea transgenerational plants. plants, events transferred imprints successive generations, even without stress. Such priming against stresses crucial their eco-evolutionary success. However, there limited literature capturing current knowledge boosting responses. this context, review focuses general concept recent field comprehensive implications tolerance with future perspectives.

According to the United Nations Environment Programme (UNEP), soil health is declining over decades and it has an adverse impact on human food security. Hence, restoration a need of hour. It known that microorganisms play vital role in remediation pollutants like heavy metals, pesticides, hydrocarbons, etc. However, indigenous microbes have limited capacity degrade these will be slow process. Genetically modified organisms (GMOs) can catalyze degradation process as their altered metabolic pathways lead hypersecretions various biomolecules favor bioremediation This review provides overview application bioengineered for by pollutants. also sheds light challenges using GMOs environmental introduction may affect normal microbial community soil. Since refers potential native survive, possible changes with are discussed. Finally, future prospects engineering applications make fertile healthy been deciphered.

Plant Growth-Promoting Rhizobacteria (PGPR): Approaches to Alleviate Abiotic Stresses for Enhancement of Growth and Development of Medicinal Plants

Sustainability, Год журнала: 2022, Номер 14(23), С. 15514 - 15514

Опубликована: Ноя. 22, 2022

Plants are constantly exposed to both biotic and abiotic stresses which limit their growth development reduce productivity. In order tolerate them, plants initiate a multitude of stress-specific responses modulate different physiological, molecular cellular mechanisms. However, many times the natural methods employed by for overcoming not sufficient require external assistance from rhizosphere. The microbial community in rhizosphere (known as rhizomicrobiome) undergoes intraspecific well interspecific interaction signaling. rhizomicrobiome, biostimulants, play pivotal role stimulating providing resilience against stress. Such rhizobacteria promote increase yield immunity known PGPR (plant promoting rhizobacteria). On basis contact, they classified into two categories, extracellular (in soil around root, root surface space) intracellular (nitrogen-fixing bacteria). They show effects on plant directly (i.e., absence pathogens) or indirectly. Generally, make niche concentrated form roots, latter exude several nutrients, such amino acids, lipids, proteins, etc. Rhizobacteria build special symbiotic relationship with section plant’s inner tissues. There free-living PGPRs potential work biofertilizers. Additionally, studies that can ameliorate effect help enhanced producing therapeutically important compounds.

As the awareness on ecological impact of chemical phosphate fertilizers grows, research turns to sustainable alternatives such as implementation solubilizing bacteria (PSB), which make largely immobile phosphorous reserves in soils available for uptake by plants. In this review, we introduce mechanisms plants facilitate P-uptake and illustrate how PSB improve bioavailability nutrient. Next, effectiveness increasing plant biomass is assessed using a meta-analysis approach. Our review demonstrates that improved does not always translate height biomass. We show effect provide an added benefit when bacterial consortia compared single strains. Moreover, commonly reported species P-solubilization, Bacillus spp. Pseudomonas spp., are outperformed scarcely implemented Burkholderia Despite similar responses monocots eudicots, responsiveness varies within both clades. Remarkably, challenges common belief less effective under field conditions greenhouse conditions. This provides innovative insights identifies key questions future promote their agriculture.

Опубликована: Май 30, 2022

For most Gram-negative bacteria, pathogenicity largely depends on the type-III secretion system that delivers virulence effectors into eukaryotic host cells. The subcellular targets for majority of these remain unknown. Xanthomonas campestris, causal agent black rot disease crucifers such as Brassica spp., radish, and turnip, XopP, a highly conserved core-effector protein produced by X. which is essential virulence. Here, we show XopP inhibits function host-plant exocyst complex direct targeting Exo70B, subunit complex, plays significant role in plant immunity. interferes with exocyst-dependent exocytosis can do this without activating NOD-like receptor guards Exo70B Arabidopsis. In way, efficiently host's pathogen-associated molecular pattern (PAMP)-triggered immunity blocking pathogenesis-related protein-1A, callose deposition, localization FLAGELLIN SENSITIVE2 (FLS2) immune to plasma membrane, thus promoting successful infection. Inhibition related defenses represents an effective strategy, indicating ability pathogens adapt avoiding responses.
