Phosphorus Uptake by Plants: From Soil to Cell Plant ...

1998-2-1  P is an important plant macronutrient, making up about 0.2% of a plant's dry weight. It is a component of key molecules such as nucleic acids, phospholipids, and ATP, and, consequently, plants cannot grow without a reliable supply of this nutrient. Pi is also involved in controlling key enzyme

Facilitation of phosphorus uptake in maize plants by ...

Phosphorus is required in relatively large amounts by plants for optimal growth, as it is a structural constituent of biomolecules involved in several key plant processes, including photosynthesis ...

Nitrogen and phosphorus variation in shallow

The study of purification efficiency and nutrient assimilation in plants was made in two riparian buffer zones with a complex of wet meadow and grey alder (Alnus incana) stand.In the less polluted Porijõgi test site, the 31 m wide buffer zone removed 40% of total nitrogen (total-N) and 78% of total phosphorus (total-P), while a heavily polluted 51 m wide buffer zone in Viiratsi retained 85% ...

Sulfur Assimilation - an overview ScienceDirect Topics

Sulfur assimilation is largely confined to plants and microorganisms since higher animals, unable to assimilate inorganic sulfur, must rely on ingested methionine and cysteine. Thus, whilst some microorganisms can reduce sulfate, thiosulfate or elemental sulfur, higher plants

What Does Phosphorus Do for Plants? Hunker

Plants grown for their seeds and fruits benefit from phosphorus, and the nutrient helps establish healthy root systems in young plants. Phosphorus supports the transfer of energy in plants, which is a different role from other plant nutrients, such as nitrogen.

Nitrogen Assimilation in Nitrogen‐Fixing Soybean

This study evaluated the hypothesis that P deficiency alters N assimilation in N 2 ‐fixing soybean plants (Glycine max L. Merr.) through effects on nodule carbohydrate status. Transport of N constituents in xylem sap, concentrations and total quantities of N fractions in plant organs, and nonstructural carbohydrate status of nodules were compared in P‐sufficient (1.0 mM P) and P ...

The Influence of Phosphate Deficiency on Legume

Phosphate (Pi) deficiency is a major nutritional factor limiting legume production, particularly in acidic and calcareous soils. Pi deficiency limits N 2 fixation, since it has been described to have a strong impact on the growth and survival of both rhizobia and host plant. Legumes have evolved complex mechanisms to cope with Pi limitation.
