Abstract. Tomato plants (Lycopersicon esculentum) grown in a complete nutrient solution for 8 days were transferred to a P-free solution of pH 6.0.Within 2 days of transfer the rate of alkalinization of the nutrient solution declined and by 4 days the solution had become acid.
Plant assimilation of phosphorus from an insoluble organic form is improved by addition of an organic anion producing Pseudomonas sp. - ScienceDirect Soil Biology and Biochemistry Volume 68, January 2014, Pages 263-269
How plants develop adaptive strategies to efficiently use nutrients on infertile soils is an important topic in plant ecology. It has been suggested that, with decreasing phosphorus (P) availability, plants increase photosynthetic P-use efficiency (PPUE) (i.e., the ratio of instantaneous photosynthetic carbon assimilation rate per unit foliar P).
The aquatic plants absorb inorganic phosphorus from lower layers of water bodies. Since phosphate salts do not dissolve in water properly, they affect plant growth in aquatic ecosystems. Absorption by Animals. The animals absorb phosphorus from the plants or by consuming plant-eating animals. The rate of the phosphorus cycle is faster in plants ...
A. Assimilation and Release by Vegetation Phosphorus assimilation and storage in plants depends on vegetative type and growth characteristics. Floating and emergent macrophytes are usually present near shorelines of streams, and the P transported in the stream may not be in direct contact with the plant roots.
Phosphorus (P) is part of the nuclei acid structure of plants which is responsible for the regulation of protein synthesis. Phosphorus plays a major role in the growth of new tissue and division of cells. Plants perform complex energy …
Abstract Phosphorus is one of the major plant nutrients that is least available in the soil. Consequently, plants have developed numerous morphological, physiological, biochemical, and molecular adaptations to acquire phosphate (Pi). Enhanced ability to acquire Pi and altered gene expression are the hallmarks of plant adaptation to Pi deficiency. The intricate …

Plant phosphorus (P)-use efficiency (PUE) is determined by a plant's capacity to produce yield (biomass or grain) per unit of P available to it. A plant can achieve a higher PUE by: (i) enhancing acquisition of P from the rhizosphere, called P-acquisition efficiency or external PUE; and/or (ii) enhancing utilisation of the acquired P towards ...
N assimilation is a main process for N utilization in plants. NR, NiR, GS, GOGAT, and enzymes related to N assimilation are encoded by a small multigene family. Although a number of works have demonstrated their functions, the functions of each member is still not fully elucidated yet, especially for functions of ASN, GDH, and CPSase in crops ...
An experiment was conducted to investigate alterations in uptake and assimilation of NO3−by phosphorus-stressed plants. Young tobacco plants (Nicotiana tabacum[L.], cv NC 2326) growing in solution culture were deprived of an external phosphorus (P) supply for 12 days.
Phosphorus. Phosphorus is a primary macronutrient (it's the P in NPK). It is required for plant respiration and photosynthesis as well as cell division and growth (and thus plant growth). It is also vital for the production of fruit and seeds and is …

Potassium transport and signaling in Arabidopsis. In root cells, after perception of external low K + stress, plants generate some signal molecules (e.g., Ca 2+, reactive oxygen species (ROS)) that regulate downstream K + channels and transporters at transcriptional and post-translational levels. The red dots represent Ca 2+ ions. AKT1, HAK5, and KUP7 are all involved in K + uptake.
Acquisition of phosphorus and nitrogen in the rhizosphere, Acquisition of phosphorus by plants Phosphorus availability and uptake Although soils generally contain a large amount of total P only a small proportion is immediately available for plant uptake Plants obtain P as orthophosphate anions (predominantly as HPO4 2− and H2PO41−) from the soil solution
ASSIMILATION OF PHOSPHORUS 4. PHOSPHORUS IN SOIL Although the total amount of P in the soil may be high, it is often present in unavailable forms or in forms that are only available outside of the rhizosphere. Few unfertilized soils release P fast enough to support the high growth rates of crop plant species.
1. Assimilation Phosphorus removal from wastewater has long been achieved through biological assimilation – incorporation of the P as an essential element in biomass, particularly through growth of photosynthetic organisms (plants, algae, and some bacteria, such as cyanobacteria). Traditionally, this was achieved through treatment ponds ...
Introduction. Plant growth and development are largely determined by nutrient availability; therefore to ensure better productivity of crop plants, it becomes essential to understand the dynamics of nutrients uptake, transport, assimilation, and their biological interactions (Wawrzyńska and Sirko, 2014).A wealth of information has been generated during …

Role of root exudates on assimilation of phosphorus in . 2020/06/03 Role of root exudates on assimilation of phosphorus in young and old Arabidopsis thaliana plants The role of root exudates has long been recognized for its potential to improve nutrient use efficiency in cropping systems.
For instance, plants can develop highly specialized morphological root traits to enhance soil exploration efficiency for phosphorus (P) assimilation, such as increasing the specific root length (SRL), and density and length of lateral roots …
Phosphorus (P) is one of the essential mineral nutrients for plants and is required in many compounds in cells and organelles [1]. These compounds are associated with numerous components of metabolism (sugar phosphates, nucleic acids, nucleotides, coenzymes, phospholipids) and are closely associated with energy transfer (triphosphonucleotides) and …

Most studies on the pH dependence of Pi uptake in higher plants have found that uptake rates are highest between pH 5.0 and 6.0, where H 2 PO 4− dominates ( Ullrich-Eberius et al., 1984: Furihata et al., 1992 ), which suggests that Pi is taken up as the monovalent form.
