“…Under control conditions, P was preferentially allocated to nucleic acid P and lipid P in both species, in line with the common P‐allocation pattern as nucleic acid P > lipid P > Pi > other P fractions (Veneklaas et al, 2012). Nucleic acid P is the major organic P pool in leaves, involved in protein synthesis, with ≥ 85% being rRNA (Suriyagoda et al, 2023; Veneklaas et al, 2012). P in cell membranes belongs to lipid P (Veneklaas et al, 2012), and metabolite P is mainly intermediate of carbon metabolism and nucleotides (Arrivault et al, 2009).…”

“…The ability of P‐hyperaccumulating species to tolerate high P concentrations and grow well is related to the above physiological traits (Aziz et al, 2015; Ye et al, 2021). P chemical forms involved in protein synthesis (nucleic acid P), membrane structure (phospholipids), carbon metabolism (metabolite P and Pi), affecting bioavailability and phytotoxicity of P to plants (Lambers, 2022; Suriyagoda et al, 2023; Yan et al, 2019). Plants can alter allocation to different P fractions when P levels change in the environment (Lambers et al, 2012; Yan et al, 2019).…”

Phosphorus (P)‐hyperaccumulators for phytoextraction from P‐polluted areas generally show rapid growth and accumulate large amounts of P without any toxicity symptom, which depends on a range of physiological processes and gene expression patterns that have never been explored. We investigated growth, leaf element concentrations, P fractions, photosynthetic traits, and leaf metabolome and transcriptome response in amphibious P‐hyperaccumulators, Polygonum hydropiper and P. lapathifolium, to high‐P exposure (5 mmol L−1), with 0.05 mmol L−1 as the control. Under high‐P exposure, both species demonstrated good growth, allocating more P to metabolite P and inorganic P (Pi) accompanied by high potassium and calcium. The expression of a cluster of unigenes associated with photosynthesis was maintained or increased in P. lapathifolium, explaining the increase in net photosynthetic rate and the rapid growth under high‐P exposure. Metabolites of trehalose metabolism, including trehalose 6‐phosphate and trehalose, were sharply increased in both species by the high‐P exposure, in line with the enhanced expression of associated unigenes, indicating that trehalose metabolic pathway was closely related to high‐P tolerance. These findings elucidated the physiological and molecular responses involved in the photosynthesis and trehalose metabolism in P‐hyperaccumulators to high‐P exposure, and provides potential regulatory pathways to improve the P‐phytoextraction capability.

Molecular membrane separation: plants inspire new technologies

Plants draw up their surrounding soil solution to gain water and nutrients required for growth, development and reproduction. Obtaining adequate water and nutrients involves taking up both desired and undesired elements from the soil solution and separating resources from waste. Desirable and undesirable elements in the soil solution can share similar chemical properties, such as size and charge. Plants use membrane separation mechanisms to distinguish between different molecules that have similar chemical properties. Membrane separation enables distribution or retention of resources and efflux or compartmentation of waste. Plants use specialised membrane separation mechanisms to adapt to challenging soil solution compositions and distinguish between resources and waste. Coordination and regulation of these mechanisms between different tissues, cell types and subcellular membranes supports plant nutrition, environmental stress tolerance and energy management. This review considers membrane separation mechanisms in plants that contribute to specialised separation processes and highlights mechanisms of interest for engineering plants with enhanced performance in challenging conditions and for inspiring the development of novel industrial membrane separation technologies. Knowledge gained from studying plant membrane separation mechanisms can be applied to developing precision separation technologies. Separation technologies are needed for harvesting resources from industrial wastes and transitioning to a circular green economy.

“…Phosphorus (P) is a vital nutrient for plant growth, playing a crucial role in sustaining terrestrial ecosystems’ productivity and functionality, especially in tropical and subtropical forest soils where P is often strongly fixed and has low availability ( Vitousek et al., 2010 ; Hidaka and Kitayama, 2011 ; Mirriam et al., 2022 ; Suriyagoda et al., 2023 ). To combat nutrient deficiencies, plants have formed symbiotic relationships with soil microorganisms, particularly mycorrhizal fungi ( Phillips et al., 2013 ; Tedersoo et al., 2020 ; Li et al., 2022 ).…”

Tree species establish mycorrhizal associations with both ectomycorrhizal (EM) and arbuscular mycorrhizal fungi (AM), which play crucial roles in facilitating plant phosphorus (P) acquisition. However, little attention has been given to the effects of EM and AM species on soil P dynamics and the underlying mechanisms in subtropical forests, where P availability is typically low. To address this knowledge gap, we selected two EM species (Pinus massoniana - PM and Castanopsis carlesii - CC) and two AM species (Cunninghamia lanceolata - Chinese fir, CF and Michelia macclurei - MM) in a common garden established in 2012 in subtropical China. We investigated soil properties (e.g., pH, soil organic carbon, total nitrogen, and dissolved organic nitrogen), soil P fractions, phospholipid fatty acids (PLFAs), enzyme activities, foliar manganese (Mn) concentration, and foliar nutrients and stoichiometry. Our findings revealed that soils hosting EM species had higher levels of resin P, NaHCO3-Pi, extractable Po, total P, and a greater percentage of extractable Po to total P compared to soils with AM species. These results indicate that EM species enhance soil P availability and organic P accumulation in contrast to AM species. Moreover, EM species exhibited higher P return to soil (indicated by higher foliar P concentrations) when compared to AM species, which partly explains higher P accumulation in soils with EM species. Additionally, resin P showed a positive correlation with acid phosphatase (ACP) activity, whereas no correlation was found with foliar Mn concentration, which serves as a proxy for the mobilization of sorbed soil P. Such findings indicate that organic P mineralization has a more substantial impact than inorganic P desorption in influencing P availability in soils hosting both EM and AM species. In summary, our study contributes to a more comprehensive understanding of the effects of mycorrhizal associations on soil P accumulation in subtropical forests and provide valuable insights into plant-soil interactions and their role in P cycling in regions with limited P availability.
