How does plant metabolites promote symbiotic phosphate acquisition?
Best insight from top research papers
Plant metabolites promote symbiotic phosphate acquisition through various mechanisms. Symbiotic fungi, such as arbuscular mycorrhizal fungi (AMF) and endophytic fungi, play a crucial role in enhancing phosphorus (P) uptake in plants. These fungi colonize the roots and increase soil phosphatase activities, leading to an elevation of soil Olsen-P and improved P availability . The symbiotic fungi also promote plant growth and root development, resulting in increased P uptake . Additionally, the symbiotic fungi up-regulate the expression of phosphate transporter genes in roots and leaves, facilitating P uptake and transport within the plant . The metabolites secreted by phosphate solubilizing bacteria (PSB) also contribute to symbiotic phosphate acquisition. PSB secrete organic acids, siderophores, exopolysaccharides, and enzymes that solubilize inorganic forms of P and mobilize organic sources of P, making them available for plant uptake . These mechanisms collectively enhance the acquisition and utilization of phosphate by plants in symbiotic associations.

How does the presence of phosphate affect the growth and metabolism of Euglena gracilis?5 answersThe presence of phosphate significantly influences the growth and metabolism of Euglena gracilis. Research shows that E. gracilis can efficiently reduce phosphorus concentrations in wastewater by 96–100%. Additionally, increasing phosphate concentrations from 4 to 14 mg/l can lead to the accumulation of biomass and photosynthetic pigments in E. gracilis. Furthermore, the induction of flocculation by adjusting pH to 8.5 enhances the pre-concentration of E. gracilis, maintaining cell integrity, chlorophyll production, and increasing paramylon production. The study also highlights that E. gracilis can utilize phosphate in wastewater for biomass production and nutrient removal, achieving high biomass productions in different effluents. Overall, phosphate plays a crucial role in the growth, metabolism, and potential applications of Euglena gracilis.
How can fungi improve nutrient uptake by plants?4 answersFungi can improve nutrient uptake by plants through various mechanisms. Firstly, fungal associations, such as arbuscular mycorrhizal (AM) fungi, increase the nutrient absorption area of plant roots, enhancing nutrient accumulation efficiency. These symbiotic fungi release phosphatases and organic acids, increasing the solubility of phosphorous in soil and promoting mycelium growth, enabling plants to acquire more phosphorous. Additionally, endophytic fungi living within plants can enhance nutrient uptake by producing substances that favor root growth, increasing nutrient interception and mass flow. Fungal endophytes can also secrete hydrolytic enzymes that enhance nutrient solubilization. Furthermore, fungi can perform beneficial interactions with other soil organisms, such as arbuscular mycorrhizal fungi, to enhance nutrient uptake. Overall, these mechanisms contribute to improved nutrient uptake by plants, reducing the need for chemical fertilizers and promoting sustainable agriculture practices.
What role does phosphorus play in plant growth?5 answersPhosphorus (P) is an essential macronutrient for plant growth and plays a vital role in various plant processes. It is involved in energy transfer, photosynthesis, nutrient movement within the plant, and the transfer of genetic characteristics. However, abiotic stresses such as temperature extremes, drought, and excess soil moisture can reduce the transport of nutrients from the roots to the shoots, leading to a decline in crop productivity. External application of P has been identified as a promising strategy to mitigate the impact of these stresses and improve stress tolerance in crops. Phosphorus availability in soils is often limited, and the poor use efficiency of phosphatic fertilizers further exacerbates this challenge. Phosphate solubilizing microorganisms (PSM) have been identified as potential agents for solubilizing and mobilizing insoluble phosphates in arid soils, thereby enhancing plant nutrition. Plants modulate complex responses to fluctuating P levels through global transcriptional regulatory networks, although the specific chromatin-level mechanisms involved in regulating P homeostasis are not yet understood. Phosphorus also plays a crucial role in mitigating abiotic stresses such as drought, salinity, heavy metal, heat, and acid stresses, and its management in agricultural lands can help plants survive under these conditions. Legume crops, in particular, require higher levels of P fertility for optimal growth and yield, and the application of phosphorus has been shown to increase various growth parameters and yield in legume crops.
Do secondary metabolites play an important role in plant growth?4 answersSecondary metabolites play a crucial role in plant growth and development. They are organic compounds produced by plants that are not directly involved in growth, development, or reproduction, but they have important functions in adaptation to the environment. These compounds have diverse chemical structures and biological functions, such as defense against herbivores and pathogens, attraction of pollinators, and regulation of growth and development. Plants produce secondary metabolites in response to environmental stresses, and these metabolites provide protection against stressors and support the growth of symbiotic organisms. Understanding the genetic basis of secondary metabolite biosynthesis and their ecological functions is crucial for developing sustainable agriculture and protecting natural ecosystems. Additionally, secondary metabolites are beneficial to mankind as nutraceuticals and pharmaceuticals. Therefore, secondary metabolites are not only important for plant survival but also have significant implications for human health and well-being.
What is the role of phosphate in agriculture?5 answersPhosphate plays a crucial role in agriculture by being an essential nutrient for crop growth and development. It is involved in various physiological and biochemical reactions and is known to be one of the most important factors limiting crop yields. However, the availability of phosphorus to plants is limited due to its strong reactive nature and formation of insoluble derivatives. This has led to the use of phosphate solubilizing microorganisms (PSMs) as biofertilizers to make soil-insoluble phosphate bioavailable for plants through solubilization and mineralization. PSMs secrete organic acids and enzymes that solubilize inorganic and organic phosphates, respectively, making them more accessible to plants. Inoculation of soils or crops with phosphate-solubilizing bacteria has shown promising results in improving plant phosphate uptake, promoting sustainable agriculture, improving soil fertility, and increasing crop yields. The use of phosphate-containing nanoparticles has also shown potential in improving agricultural productivity by reducing the amount of phosphate required and improving plant development and photosynthesis.
How does phosphorus uptake influence nodules in legumes?5 answersPhosphorus uptake influences nodules in legumes by affecting their formation, function, and energy costs. Legumes have a higher requirement for phosphorus due to symbiotic nitrogen fixation (SNF) occurring in specialized organs called nodules. In phosphorus-deficient conditions, legumes exhibit impaired SNF activity, reduced growth, and altered phosphorus distribution in leaves, roots, and nodules. Phosphorus stress leads to membrane lipid remodeling in nodules, with changes in the distribution of specific phosphatidylcholine (PC) species. Legumes adapt to phosphorus deficiency by internally recycling phosphorus, reducing phosphorus uptake, and increasing phosphohydrolase exudation. The maintenance of phosphorus homeostasis in nodules is crucial for rhizobia-legume symbiosis under phosphorus scarcity. Legumes employ various mechanisms to stabilize phosphorus levels in nodules, including elevated phosphorus allocation, formation of a strong phosphorus sink, direct phosphorus acquisition, and phosphorus remobilization from organic-P containing substances. Understanding the physiological, biochemical, and molecular reprogramming involved in legume adaptation to phosphorus deficiency is essential for enhancing phosphorus uptake and nodulation in legume crops.
