2020-6-3  Introduction. Phosphorus is an essential element for plant growth and development [], and a non-renewable resource [2,3].Despite the fact that the total amount of phosphorus is high in most agricultural soils, crop yields are often limited by low availability due to the non-soluble form and low mobility of this nutrient [4,5].It has been estimated that residual phosphorus fertilizer known as ...

Phosphorus Stress Effects on Assimilation of Nitrate

Abstract. An experiment was conducted to investigate alterations in uptake and assimilation of NO 3 − 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.On selected days, plants were exposed to 15 NO 3 − during the 12 hour light period to determine changes in NO ...

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

1998-2-1  UPDATE ON PHOSPHORUS UPTAKE. 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 reactions and in the ...

Biotechnology of nutrient uptake and assimilation in plants

Plants require a complex balance of mineral nutrients to reproduce successfully. Because the availability of many of these nutrients in the soil is compromised by several factors, such as soil pH, cation presence, and microbial activity, crop plants depend directly on nutrients applied as fertilizer

PHOSPHATE ACQUISITION Annual Review of Plant Biology

2019-7-17  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 mechanisms involved in ...

Phosphorus Basics – The Phosphorus Cycle

2015-5-5  Most plants are only about 0.2% P by weight, but that small amount is critically important. Phosphorus is an essential component of adenosine triphosphate (ATP), which is involved in most biochemical processes in plants and enables them to extract nutrients from the soil. Phosphorus also plays a critical role in cell development and DNA formation.

2013-11-6  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).
