Drylands are stressful environment for plants growth and production. Plant growth-promoting rhizobacteria (PGPR) acts as a rampart against the adverse impacts of drought stress in drylands enhances plant is helpful agricultural sustainability. PGPR improves tolerance by implicating physio-chemical modifications called rhizobacterial-induced endurance resilience (RIDER). The RIDER response includes; alterations phytohormonal levels, metabolic adjustments, production bacterial exopolysaccharides (EPS), biofilm formation, antioxidant resistance, including accumulation many suitable organic solutes such carbohydrates, amino acids, polyamines. Modulation moisture status these PGPRs one primary mechanisms regulating growth, but studies on their effect survival scarce sandy/desert soil. It was found that inoculated showed high to water-deficient conditions delaying dehydration maintaining plant’s water at an optimal level. had recovery rate after rewatering interms similar biomass flowering compared non-stressed plants. These enhance also elicit induced systemic resistance scarcity. root architecture, thereby improving nutrient uptake. promoted stress-responsive metabolites sugars, sugar alcohols. play substantial role development strengthen defensive system various biotic abiotic stresses, particular stress.

Microbes of the phytomicrobiome are associated with every plant tissue and, in combination form holobiont. Plants regulate composition and activity their bacterial community carefully. These microbes provide a wide range services benefits to plant; return, provides microbial reduced carbon other metabolites. Soils generally moist environment, rich which supports extensive soil communities. The rhizomicrobiome is great importance agriculture owing diversity root exudates cell debris that attract diverse unique patterns colonization. play key roles nutrient acquisition assimilation, improved texture, secreting modulating extracellular molecules such as hormones, secondary metabolites, antibiotics various signal compounds, all leading enhancement growth. compounds they secrete constitute valuable biostimulants pivotal stress responses. Research has demonstrated inoculating plants plant-growth promoting rhizobacteria (PGPR) or treating microbe-to-plant can be an effective strategy stimulate crop Furthermore, these strategies improve tolerance for abiotic stresses (egs. drought, heat, salinity) likely become more frequent climate change conditions continue develop. This discovery resulted multifunctional PGPR-based formulations commercial agriculture, minimize use synthetic fertilizers agrochemicals. review update about role PGPR from collection commercialization low-cost agricultural inputs. First, we introduce concept context underlying food security 21st century.

Root-associated microbes can improve plant growth, and they offer the potential to increase crop resilience future drought. Although our understanding of complex feedbacks between microbial responses drought is advancing, most knowledge comes from non-crop plants in controlled experiments. We propose that research efforts should attempt quantify relationships traits, explicitly focus on food crops, include longer-term experiments under field conditions. Overall, we highlight need for improved mechanistic during, particularly after, This requires integrating ecology with plant, microbiome, molecular approaches central making production more resilient climate.

Abstract Drought stress, which causes a decline in quality and quantity of crop yields, has become more accentuated these days due to climatic change. Serious measures need be taken increase the tolerance plants acute drought conditions likely occur global warming. stress many physiological biochemical changes plants, rendering maintenance osmotic adjustment highly crucial. The degree plant resistance varies with species cultivars, phenological stages plant, duration exposure stress. Osmoregulation under low water potential relies on synthesis accumulation osmoprotectants or osmolytes such as soluble proteins, sugars, sugar alcohols, quaternary ammonium compounds, amino acids, like proline. This review highlights role water‐stressed enzymes entailed their metabolism. It will useful, especially for researchers working development drought‐resistant crops by using metabolic‐engineering techniques.

The application of microbial inoculants (biofertilizers) is a promising technology for future sustainable farming systems in view rapidly decreasing phosphorus stocks and the need to more efficiently use available nitrogen (N). Various taxa are currently used as biofertilizers, based on their capacity access nutrients from fertilizers soil stocks, fix atmospheric nitrogen, improve water uptake or act biocontrol agents. Despite existence considerable knowledge effects specific comprehensive quantitative assessment performance biofertilizers with different traits such solubilization N fixation applied various crops at global scale missing. We conducted meta-analysis quantify benefits terms yield increase, efficiency, 171 peer reviewed publications that met eligibility criteria. Major findings are: (i) superiority biofertilizer dry climates over other climatic regions (yield response: climate +20.0 ± 1.7%, tropical +14.9 1.2%, oceanic +10.0 3.7%, continental +8.5 2.4%); (ii) meta-regression analyses revealed response due was generally small low P levels; efficacy increased along higher levels order arbuscular mycorrhizal fungi (AMF), solubilizers, fixers; (iii) meta-regressions showed success inoculation AMF greater organic matter content neutral pH. Our analysis provides basis guidance proper choice biofertilizers.

Drought is one of the major constraints to rain-fed agricultural production, especially under climate change conditions. Plants evolved an array adaptive strategies that perceive stress stimuli and respond these signals through specific mechanisms. Abscisic acid (ABA) a premier signal for plants drought plays critical role in plant growth development. ABA triggers variety physiological processes such as stomatal closure, root system modulation, organizing soil microbial communities, activation transcriptional post-transcriptional gene expression, metabolic alterations. Thus, understanding mechanisms ABA-mediated responses ensuring crop yield global food security. In this review, we highlighted how adjust perception, levels ABA- drought-related genes, regulation pathways alter at both cellular whole level. Understanding synergetic will strengthen our knowledge develop stress-resilient crops integrated advanced biotechnology approaches. This review elaborate on genetic, biochemical, molecular plants, which advancement biology research.

Plants interact simultaneously with each other and soil biota, yet the relative importance of competition vs. plant-soil feedback (PSF) on plant performance is poorly understood. Using a meta-analysis 38 published studies 150 species, we show that effects interspecific (either growing plants competitor or singly, comparing inter- intraspecific competition) PSF (comparing home away soil, live sterile control fungicide-treated soil) depended treatments but were predominantly negative, broadly comparable in magnitude, additive synergistic. Stronger competitors experienced more negative than weaker when controlling for density (inter- to competition), suggesting could prevent competitive dominance promote coexistence. When was measured against strength overwhelmed PSF, indicating may depend not only neighbour identity also density. We evaluate how PSFs might across resource gradients; will likely strengthen interactions high environments enhance facilitative low-resource environments. Finally, provide framework filling key knowledge gaps advancing our understanding these biotic influence community structure.
