Compared with the other major nutrients, phosphorus is by far the least mobile and available to plants in most soil conditions. Although phosphorus is abundant in soils in both organic and inorganic forms, it is frequently a major or even the prime limiting factor for plant growth. The bioavailability of soil inorganic phosphorus in the rhizosphere varies considerably with plant species, nutritional status of soil and ambient soil conditions. To circumvent phosphorus deficiency, phosphate… Expand

Role of Phosphate-Solubilizing Fungi in Sustainable Agriculture
A variety of nutrients such as nitrogen (N) and phosphorus (P) are generally used by crop plants extensively. Available P is one of the prominent limiting and decisive factors that determine theExpand
Phosphate-Solubilizing Microorganisms in Sustainable Agriculture: Genetic Mechanism and Application
Phosphorus (P) is the second important nutrient in terms of plant requirement and uptake. Though it is present in the soil in both organic and inorganic forms, its accessibility is constrained as itExpand
Phosphate-Solubilizing Rhizobacteria: Diversity, Mechanisms, and Prospects in Sustainable Agriculture
TLDR
This review particularly focuses on the P solubilizing rhizobacteria and evaluates their diversity, mechanisms of action, and prospects in sustainable agriculture based on the present and future scenario of their application. Expand
Rhizobacterial Phosphate Solubilizers in Sustainable Agriculture: Concepts and Prospects
Phosphorous is the second most important macroelement in plant nutrition. The availability of the P present in the soil and being applied through chemical fertilizers is very poor due to fixation inExpand
Plant growth promotion by phosphate solubilizing fungi – current perspective
TLDR
The present review focuses on the mechanisms of phosphate solubilization, development and mode of fungal inoculants application and mechanisms of growth promotion by phosphate-solubilizing fungi for crop productivity under a wide range of agro-ecosystems. Expand
Phosphorus Cycling: Prospects of Using Rhizosphere Microorganisms for Improving Phosphorus Nutrition of Plants
Phosphorus (P) is the second most essential nutrient after nitrogen for plant growth and development. The available form of P is generally low even in fertile soils throughout the world due to highExpand

Solubilization of inorganic phosphates by fungi isolated from agriculture soil
Most agricultural soils contain large reserves of phosphorus (P), a considerable part of which accumulates as a consequence of regular applications of P fertilizers. However, a greater part of soilExpand
Microbially Mediated Increases in Plant-Available Phosphorus
TLDR
This chapter elaborates the microbially mediated increases in plant-available phosphorus (P) under soil conditions, one of the most important being the activity of the PS microbial population already in the soil. Expand

TLDR
Many soil fungi, predominantly of the genera Aspergillus and Penicillium, have been shown to possess the ability to solubilize sparingly soluble phosphates in vitro by secreting inorganic or organic acids. Expand
Phosphate solubilisation in solution culture by the soil fungus Penicillium radicum

TLDR
The absolute growth depression of VAM plants at the higher P level was likely due to P toxicity, and high leaf P and K concentrations may have interfered with carbohydrate distribution and utilization in these symbioses. Expand
