1、Plant adaptation to low phosphorus availability: Core signaling

Plants preferentially absorb P as orthophosphate (Pi), an ion that displays low solubility and that is readily fixed in the soil, making P limitation a condition common to many soils and Pi fertilization an inefficient practice.

2、Phosphorus Acquisition and Utilization in Plants

Tremendous progress has been made on molecular aspects of plant phosphorus (P) nutrition, often without heeding information provided by soil scientists, ecophysiologists, and crop physiologists. This review suggests ways to integrate information from different disciplines.

3、Phosphorus acquisition and use: critical adaptations by plants for

Plants have evolved a diverse array of strategies to obtain adequate P under limiting conditions, including modifications to root architecture, carbon metabolism and membrane structure, exudation of low molecular weight organic acids, protons and enzymes, and enhanced expression of the numerous genes involved in low-P adaptation.

4、Phosphate Uptake and Transport in Plants: An Elaborate Regulatory

Plants absorb Pi from the soil through their roots and transfer Pi to various organs or tissues through phosphate transporters, which are precisely controlled at the transcript and protein levels.

5、Phosphate Uptake and Transport in Plants: An Elaborate

Recently, the molecular mechanisms of plant Pi signaling have become clearer. Plants absorb Pi from the soil through their roots and transfer Pi to various organs or tissues through phosphate transporters, which are precisely controlled at the transcript and protein levels.

Phosphate acquisition and metabolism in plants

In this primer, we give an overview of the factors limiting phosphorus acquisition by plants and highlight various pathways and strategies plants have evolved at the level of development, metabolism and signal transduction to adapt to phosphorus deficiency.

Adaptive strategies of plants to conserve internal phosphorus under P

In this review, we have discussed the adaptive strategies that conserve the use of P and maintain cellular Pi homeostasis in the cytoplasm.

Lilies, as perennial herbaceous plants, have strict and delicate nutrient requirements during their growth. Phosphorus, an essential element for plant development, plays a critical role in the growth and flowering of lilies. when lilies lack phosphorus, their ability to absorb this nutrient is impaired, affecting the health of the plant and blooming. Below are the detailed mechanisms of phosphorus absorption in phosphorus-deficient lilies:

I. Root Absorption

1. Root Structure: Lilies possess a well-developed root system with strong absorptive capabilities. The roots penetrate deep into the soil, accessing phosphorus from lower layers.
2. Root Distribution: Roots are distributed across multiple soil layers, with a higher density in the upper layers, facilitating efficient phosphorus uptake.
3. Root Activity: Healthy roots maintain active respiration and metabolism, enhancing their capacity to absorb phosphorus.

II. Root Tip Absorption

1. Root Tip Structure: The root tip contains specialized cells rich in phosphorus-absorbing capabilities, directly extracting phosphorus from the soil.
2. Root Tip Activity: The vitality of root tip cells determines absorption efficiency. Highly active cells absorb phosphorus more effectively, while weaker cells perform poorly.
3. Root Tip Morphology: Dense root hairs in the root tip improve phosphorus capture by increasing surface area.

III. Stem and Leaf Absorption

1. Leaf Structure: Leaves contain abundant chloroplasts and photosynthetic pigments, which promote phosphorus absorption.
2. Leaf Activity: Leaf vitality correlates with phosphorus uptake. Active leaves efficiently capture and transport phosphorus to other parts of the plant.
3. Leaf Morphology: Broad, flat leaves enhance phosphorus absorption, while narrow, erect leaves are less effective.

IV. Stem Absorption

1. Stem Structure: Stems contain woody fibers and lignin, which inhibit phosphorus absorption.
2. Stem Activity: Active stems resist lignin’s inhibitory effects, improving phosphorus uptake.
3. Stem Morphology: Thick, robust stems better counteract lignin’s limitations, whereas thin, weak stems absorb less efficiently.

V. Stem Tip Absorption

1. Stem Tip Structure: Specialized tissues in the stem tip facilitate phosphorus absorption.
2. Stem Tip Activity: Highly active stem tips absorb phosphorus more effectively than less active ones.
3. Stem Tip Morphology: Long, erect stem tips absorb phosphorus better, while short, flat tips perform poorly.

Under phosphorus deficiency, lilies rely on coordinated absorption mechanisms involving roots, root tips, stems, leaves, and stem tips. These processes work synergistically to ensure adequate phosphorus supply at different growth stages. Fertilization strategies should consider the plant’s growth stage and soil conditions to optimize phosphorus availability while avoiding soil salinization caused by over-fertilization.
