Phosphorus (P) is an essential and limiting nutrient in soil tightly linked to fertility productivity. Microorganisms have developed different mechanisms respond P scarcity increase its availability soil, which are susceptible change under contrasting land uses. Here, we calculated compared metagenomic redundancy, as a measurement of ecosystem potential capacity, 23 key functional genes related organic mineralization, inorganic solubilization P-starvation response regulation forest, grassland cropland soils through mining public sequence repository. The redundancy those all currently published genomes (genome redundancy) from archaea, bacteria fungi was also studied. Microbes croplands grasslands showed higher (i.e., mineralize the action alkaline phosphatases (phoA, phoD phoX genes) solubilize (gcd pqqC) by producing gluconic acid than forests. Instead, capacity microbes phosphonates C–P lyases (phnG, phnH, …, phnM) found be impact use on encoding phytases (appA 3-phytase) dependent type phytase. Intermetagenome (potentiality per metagenome unit) reached maximum values for phosphatase production, starvation, denoting crucial role that these functions cycling. Proteobacteria, within Bacteria, Euryarchaeota, Archaea, greatest genomic scarcity. However, seems more restricted. present study provides overview how microbial regulate potentially with taxonomy microbes.

Soil phosphorus transformation and plant uptake driven by phosphate-solubilizing microorganisms

Frontiers in Microbiology, Journal Year: 2024, Volume and Issue: 15

Published: March 27, 2024

Phosphorus (P) is an important nutrient for plants, and a lack of available P greatly limits plant growth development. Phosphate-solubilizing microorganisms (PSMs) significantly enhance the ability plants to absorb utilize P, which improving turnover yield. This article summarizes analyzes how PSMs promote absorption utilization nutrients by from four perspectives: types functions PSMs, phosphate-solubilizing mechanisms, main functional genes, impact complex inoculation on acquisition. reviews physiological molecular mechanisms phosphorus solubilization promotion with focus analyzing soil microbial communities its interaction root exudates. In order better understand their role in transformation provide prospects research promoting absorption. mainly activate insoluble through secretion organic acids, phosphatase production, mycorrhizal symbiosis, symbiosis indirectly activates via carbon exchange. can secrete acids produce phosphatase, plays crucial cycling, related genes are involved regulating P-solubilization ability. uptake great significance deeper understanding PSM-mediated utilization, efficiency agriculture.

Published: Dec. 12, 2023

Rhizosphere microbes play critical roles for plant's growth and health. Among them, the beneficial rhizobacteria have potential to be developed as biofertilizer or bioinoculants sustaining agricultural development. The efficient rhizosphere colonization of these is a prerequisite exerting their plant functions, but colonizing process underlying mechanisms not been thoroughly reviewed, especially nonsymbiotic rhizobacteria. This review systematically analyzed root compared it with that symbiotic pathogenic bacteria. also highlighted approaches improve efficiency proposed study rhizobacterial from holistic perspective microbiome under more natural conditions.

Medicinal plants (MPs) are important resources widely used in the treatment and prevention of diseases have attracted much attention owing to their significant antiviral, anti-inflammatory, antioxidant other activities. However, soil degradation, caused by continuous cropping, excessive chemical fertilizers pesticide residues heavy metal contamination, seriously restricts growth quality formation MPs. Microorganisms, as major biota soil, play a critical role restoration land ecosystem. Rhizosphere microecology directly or indirectly affects development, metabolic regulation active ingredient accumulation Microbial resources, with advantages economic efficiency, harmless environment non-toxic organisms, been recommended promising alternative conventional pesticides. The introduction beneficial microbes promotes adaptability MPs adversity stress enhancing fertility, inhibiting pathogens inducing systemic resistance. On hand, it can improve medicinal removing pollutants, reducing absorption harmful substances regulating synthesis secondary metabolites. ecological benefits microbiome agricultural practices increasingly recognized, but current understanding interaction between conditions, root exudates microbial communities mechanism rhizosphere affecting metabolism is still quite limited.

Abstract Soils are a main repository of biodiversity harbouring immense diversity microbial species that plays central role in fundamental ecological processes and acts as the seed bank for emergence plant microbiome cropland ecosystems. Crop‐associated microbiomes play an important shaping performance, which includes but not limited to nutrient uptake, disease resistance, abiotic stress tolerance. Although our understanding structure function soil has been rapidly advancing, most knowledge comes from ecosystems natural environment. In this review, we present overview current communities along soil–plant continuum agroecosystems. To characterize mechanisms community assembly crop microbiomes, explore how host environmental factors such developmental stage, pathogen invasion, land management shape structure, co‐occurrence patterns, crop‐microbiome interactions. Particularly, relative importance deterministic stochastic is illustrated under different conditions, potential sources keystone taxa described. Finally, highlight few questions perspectives future research.
