Phosphorus Acquisition and Utilization in Plants

Annual Review of Plant Biology, Год журнала: 2021, Номер 73(1), С. 17 - 42

Опубликована: Дек. 15, 2021

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 from different disciplines. When P availability is very low, P-mobilizing strategies are more effective than mycorrhizal strategies. Soil parameters largely determine how much roots can acquire P-impoverished soil, kinetic properties transporters less important. Changes in the expression avoid toxicity. Plants vary widely photosynthetic P-use efficiency, photosynthesis per unit leaf P. The challenge discover what trade-offs patterns investment fractions. Less may save P, but costs incurred? Are these acceptable for crops? These questions be resolved only concerted action scientists working at both physiological levels, rather pursuing problems independently.

Linking root exudation to belowground economic traits for resource acquisition

New Phytologist, Год журнала: 2021, Номер 233(4), С. 1620 - 1635

The concept of a root economics space (RES) is increasingly adopted to explore trait variation and belowground resource-acquisition strategies. Much progress has been made on interactions morphology mycorrhizal symbioses. However, exudation, with significant carbon (C) cost (c. 5-21% total photosynthetically fixed C) enhance resource acquisition, remains missing link in this RES. Here, we argue that incorporating exudation into the structure RES key holistic understanding soil nutrient acquisition. We highlight different functional roles exudates phosphorus (P) nitrogen (N) Thereafter, synthesize emerging evidence illustrates how interacts symbioses at level species individual plant contrasting patterns evolved P-impoverished vs N-limited environments. Finally, propose new conceptual framework, integrating three groups traits better capture complexity Such deeper integrated dynamic morphology, will provide valuable insights mechanisms underlying coexistence for sustainable managed systems.

Root traits with team benefits: understanding belowground interactions in intercropping systems

Plant and Soil, Год журнала: 2021, Номер 471(1-2), С. 1 - 26

Опубликована: Дек. 2, 2021

Abstract Background The potential benefits of intercropping are manifold and have been repeatedly demonstrated. Intercropping has the to create more productive resilient agroecosystems, by improving land utilisation, yield stability, soil quality, pest, disease weed suppression. Despite these benefits, significant gaps remain in understanding ecological mechanisms that govern outcomes when crop species grown together. A major part plant-plant interactions takes place belowground often overlooked. Scope This review synthesises current evidence for competition, niche differentiation facilitation, with aim identifying root traits influence processes contributing enhanced performance intercrops compared monocultures. We identify a suite potentially complementary maximising intercropping. These underpin improved exploration, efficient resource use, suppression soil-borne pathogens pests intercrops. Conclusion brings together underpinning between intercropped roots, how their plasticity can promote positive outcomes. Root trait ‘ideotypes’ partners identified could be selected improvement. highlight importance examining consider both spatial temporal distribution roots rhizosphere aid complementarity through facilitation. Breeding ideotypes specific beneficial traits, combined considerations optimal spatio-temporal arrangement ratios component crops, essential next steps adoption as sustainable farming practice.

Allelopathy and Allelochemicals in Grasslands and Forests

Forests, Год журнала: 2023, Номер 14(3), С. 562 - 562

Опубликована: Март 13, 2023

Plants can produce and release allelochemicals to interfere with the establishment growth of conspecific interspecific plants. Such allelopathy is an important mediator among plant species in natural managed ecosystems. This review focuses on grasslands forests. Allelopathy drives invasion, exacerbates grassland degradation contributes forest regeneration. Furthermore, autotoxicity (intraspecific allelopathy) frequently occurs pastures tree plantations. Various specialized metabolites, including phenolics, terpenoids nitrogen-containing compounds from herbaceous woody are responsible for Terpenoids a diversity metabolites qualitative occurring annual grasslands, while phenolics few quantitative perennial Importantly, mediate below-ground ecological interactions plant–soil feedback, subsequently affecting biodiversity, productivity sustainability Interestingly, allelopathic plants discriminate identity neighbors via signaling chemicals, adjusting production allelochemicals. Therefore, chemicals synergistically interact regulate intraspecific forests have provided fascinating insights into plant–plant their consequences sustainability, contributing our understanding terrestrial ecosystems global changes.

Recent insights into the metabolic adaptations of phosphorus-deprived plants

Inorganic phosphate (Pi) is an essential macronutrient required for many fundamental processes in plants, including photosynthesis and respiration, as well nucleic acid, protein, membrane phospholipid synthesis. The huge use of Pi-containing fertilizers agriculture demonstrates that the soluble Pi levels most soils are suboptimal crop growth. This review explores recent advances concerning understanding adaptive metabolic plants have evolved to alleviate negative impact nutritional deficiency. Plant starvation responses arise from complex signaling pathways integrate altered gene expression with post-transcriptional post-translational mechanisms. resultant remodeling transcriptome, proteome, metabolome enhances efficiency root acquisition soil, assimilated throughout plant. We emphasize how up-regulation high-affinity transporters intra- extracellular scavenging recycling enzymes, organic acid anion efflux, remodeling, remarkable flexibility plant metabolism bioenergetics contribute survival Pi-deficient plants. research field enabling development a broad range innovative promising strategies engineering phosphorus-efficient crops.
