Dec 12, 2024 · Relative increment of leaf P concentration (P leaf) and leaf P fractions (concentrations, mg kg −1) for exotic species (ES), eurytopic native species (ENS) and stenotopic native species (SNS). Values (means ± SE) were compared by …

Dec 15, 2022 · Drought exacerbates the limitation of phosphorus (P) deficiency to crop growth and agricultural production. Leaf P resorption is an efficient strategy that a plant develops to cope with P deficiency. However, few studies have explored the …

Dec 24, 2024 · Leaf phosphorus (P) is essential in plant physiology and is partitioned into five functional fractions, each reflecting distinct biochemical roles. Orthophosphate P (Pi) serves primarily as a storage form in vacuoles.

Jan 8, 2024 · Adaptations of plants to phosphorus (P) deficiency include reduced investment of leaf P in storage (orthophosphates in vacuoles), nucleic acids and membrane lipids. Yet, it is unclear how these adaptations are associated with plant ecological strategies.

Nov 23, 2021 · We emphasize three main conclusions with regards to the ecosystem P response to 25 yr of warming in the arctic tundra. First, we found community level increases in plant leaf P and increases in plant litter mass, presumably resulting in …

Nov 3, 2022 · Leaf phosphorus (P) comprises four major fractions: inorganic phosphate (P i), nucleic acids, phospholipids, P-containing metabolites and a residual fraction. In this review paper, we investigated whether allocation of P fractions varies among groups of terrestrial vascular plants, and is indicative of a species' strategy to use P efficiently.

Nov 25, 2023 · Inorganic phosphate is a significant fraction of the total leaf P pool when P availability is high (Veneklaas et al., 2012). Nucleic acid P is typically the largest among the organic P fractions (Suriyagoda et al., 2023). Leaf P allocation patterns give an …

Apr 4, 2023 · Phosphorus (P) is a key limiting nutrient for plant growth, yet it is unclear how the allocation of leaf P among different functions is coordinated with the LES. We addressed this question among 12 evergreen woody species co-occurring on P-impoverished soils in south-eastern Australia.

Apr 1, 2025 · This assessment allowed us to quantitatively evaluate the effects of N and P additions alone and interactively on leaf P allocation and use strategies. Nitrogen addition (exacerbating P limitation) reduced the concentrations of leaf total P and different leaf P fractions.

Aug 6, 2020 · The findings provide insight into how overall leaf P concentrations are partitioned, including that P investment in structural components of the leaf like membrane phospholipids is remarkably conservatively regulated.
