Summary
Phosphate-solubilizing microorganisms (PSMs) enhance plant phosphorus (P) uptake by releasing organic acids and phosphatases. This review explores PSM mechanisms for improving P availability and plant growth.
Area of Science:
- Agricultural Science
- Microbiology
- Soil Science
Background:
- Phosphorus (P) is crucial for plant development, but its availability is often limited in soils.
- Phosphate-solubilizing microorganisms (PSMs) can enhance plant P acquisition and utilization.
- Understanding PSM functions is key to improving crop yield and nutrient cycling.
Purpose of the Study:
- To review the mechanisms by which PSMs promote plant phosphorus absorption and utilization.
- To analyze the roles of PSM types, solubilizing mechanisms, functional genes, and co-inoculation.
- To explore PSM interactions with soil microbial communities and root exudates.
Main Methods:
- Literature review of studies on PSMs and plant phosphorus uptake.
- Analysis of physiological and molecular mechanisms of phosphorus solubilization.
- Examination of the impact of PSMs on soil P transformation and plant growth.
Main Results:
- PSMs activate insoluble P via organic acid secretion, phosphatase production, and mycorrhizal symbiosis.
- Functional genes regulate the P-solubilization capabilities of PSMs.
- PSMs influence soil microbial communities and interact with root exudates.
Conclusions:
- PSMs are vital for enhancing soil P availability and plant P uptake.
- Further research on PSMs can improve phosphorus use efficiency in agriculture.
- PSM-mediated soil P cycling and plant P nutrition are significant areas for study.

01:21The Phosphorus Cycle
36.8K
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems.

02:11The Roles of Bacteria and Fungi in Plant Nutrition
35.3K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

01:20Overview of Nitrogen Metabolism
7.9K
Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of ammonia, ammonium ions, nitrate, nitrite, or nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.

02:35Key Elements for Plant Nutrition
18.7K
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the...

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

02:34Water and Mineral Acquisition
33.0K
Specialized tissues in plant roots have evolved to capture water, minerals, and some ions from the soil. Roots exhibit a variety of branching patterns that facilitate this process. The outermost root cells have specialized structures called root hairs that increase the root surface, thus increasing soil contact. Water can passively cross into roots, as the concentration of water in the soil is higher than that of the root tissue. Minerals, in contrast, are actively transported into root cells.
