Phosphorus is an essential nutrient for all life on earth and has a major impact plant growth crop yield. The forms of phosphorus that can be directly absorbed utilized by plants are mainly HPO42- H2PO4-, which known as usable phosphorus. At present, the total content soils worldwide 400-1000 mg/kg, only 1.00-2.50% plant-available, seriously affects development agriculture, resulting in high level scarcity available Traditional methods applying fertilizer cannot address deficiency problems; they harm environment ore material nonrenewable natural resource. Therefore, it imperative to find alternative environmentally compatible economically viable strategies scarcity. Phosphorus-solubilizing bacteria (PSB) convert insoluble soil into plants, thus improving uptake utilization plants. However, there no clear systematic report mechanism action PSB. this paper summarizes discovery process, species, distribution PSB, focusing physiological mechanisms outlining processes acidolysis, enzymolysis, chelation complexation reactions related genes regulating PSB acidolysis enzymatic well phosphate transport molecular direction its pathway examined. effects structure abundance microbial communities also described, illustrating how interact with microorganisms indirectly increase amount soil.

Abstract Soil hosts diverse microbial communities including bacteria, fungi, archaea, protozoans and nematodes among others, which are fundamental to sustainable agriculture drive essential processes that underpin soil fertility, plant health, ecosystem resilience. They promote growth through mechanisms like nitrogen fixation, phosphorus solubilization, production of growth-promoting substances, enhancement nutrient uptake, improvement structure detoxification harmful substances. Recently, there has been increasing interest in utilizing microorganisms improve health boost efficiency, despite limited understanding diversity, microbe-plant interactions, translating laboratory findings field conditions. This is driven by the urgent need feed growing global population, placing pressure on arable land produce high-quality yields. Conventionally, synthetic fertilizers have extensively used provide nutrients, growth, increase crop productivity. Although revolutionized since green revolution, their overuse significantly harmed reduced review synthesizes current knowledge microbes influence agricultural practices, with a focus cycling plant–microbe interactions. We discuss functions important groups, such as nitrogen-fixing phosphorus-solubilizing bacteria (PSB), fungi. Furthermore, we factors highlight gaps future research maximize potential use agriculture. Understanding significance key increases harnessing vital contributors

Plant growth-promoting rhizobacteria (PGPR) applications have emerged as an ideal substitute for synthetic chemicals by their ability to improve plant nutrition and resistance against pathogens. In this study, we isolated fourteen root endophytes from healthy wheat roots cultivated in Tunisia. The isolates were identified based 16S rRNA gene sequences. They belonged Bacillota Pseudomonadota taxa. Fourteen strains tested defense-eliciting potentials on durum under greenhouse conditions, vitro biocontrol power Fusarium culmorum , ascomycete responsible seedling blight, foot rot, head blight diseases of wheat. We found that all the improved shoot and/or biomass accumulation, with Bacillus mojavensis Paenibacillus peoriae Variovorax paradoxus showing strongest promoting effects. These physiological effects correlated traits bacterial endophytes, which produced indole-related compounds, ammonia, hydrogen cyanide (HCN), solubilized phosphate zinc. Likewise, defense accumulations modulated lastingly systematically leaves strains.

Due to its adsorption with aluminum and iron hydroxides, phosphorus viability is low in acidic soils; thus, the aim of this study was isolate identify bacteria from rhizosphere four legumes growing soils Cumbaza Sub-basin, San Martín, Peru, as well characterize their ability solubilize phosphate phosphate. The isolation process conducted on TSA medium isolates were classified based origin morphocolonial characteristics, bacillary shape being most frequent, followed by cocci. To assess solubilization phosphates, liquid GELP employed. Sixteen strains selected, among which three stood out for effectiveness solubilizing AlPO4 (Sfcv-098-02, 22.65 mg L−1; Sfc-093-04, 26.50 Sfcv-041-01-2, 55.98 L−1) one FePO4 (Sfcr-043-02, 32.61 L−1). These molecularly characterized, identified Enterobacter sp., Pseudomonas Staphylococcus sp. Additionally, a decrease pH observed reactions, values ranging 5.23 3.29, enhanced solubilization. This suggests that selected could be used improve availability agricultural soils.

Maize is an important cereal in many developed and developing countries of the world. One primary challenges for maize cultivation soil acidity. Acidic a major constrain achieving food security requiring sustainable solutions. Biochar, pyrogenic carbon-rich material, carries reactive surfaces (i.e., high surface area variable charges). Therefore, it facilitates nutrient retention gradual release to plants, thereby supporting crop growth. However, combine effects functionalized biochar with microbes on phosphorus (P) bioavailability plant performance remain unclear.
