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 developmental responses to phosphorus nutrition

Journal of Integrative Plant Biology, Год журнала: 2021, Номер 63(6), С. 1065 - 1090

Опубликована: Март 12, 2021

Abstract Phosphorus is an essential macronutrient for plant growth and development. Root system architecture (RSA) affects a plant's ability to obtain phosphate, the major form of phosphorus that plants uptake. In this review, I first consider relationship between RSA phosphorus‐acquisition efficiency, describe how external conditions both induce impose changes in crops model Arabidopsis , discuss whether shoot status there universal root developmental response across all species. then summarize current understanding molecular mechanisms governing responses deficiency. also explore possible reasons inconsistent results reported by different research groups comment on relevance some studies performed under laboratory what occurs natural environments.

Root exudates contribute to belowground ecosystem hotspots: A review

Frontiers in Microbiology, Год журнала: 2022, Номер 13

Опубликована: Окт. 5, 2022

Root exudates are an essential carrier for material cycling, energy exchange, and information transfer between the belowground parts of plants soil. We synthesize current properties regulators root their role in ecosystem as substances cycle signal regulation. discussed composition amount production mechanism, indicating that plant species, growth stage, environmental factors, microorganisms primary influence factors. The specific mechanisms by which secretions mobilize soil nutrients were summarized. First, improve nutrient status releasing organic acids acidification chelation. Then, accelerated SOC turnover due to dual impacts, forming destabilizing aggregates MASOC. Eventually, mediate plant–plant interaction plant–microbe interaction. Additionally, a summary collection methods is presented.

Phosphate-Dependent Regulation of Growth and Stresses Management in Plants

The importance of phosphorus in the regulation plant growth function is well studied. However, role inorganic phosphate (Pi) molecule mitigation abiotic stresses such as drought, salinity, heavy metal, heat, and acid are poorly understood. We revisited peer-reviewed articles on characteristics that (P)-dependently regulated under sufficient-P low/no-P starvation alone or either combined with one mentioned stress. found photosynthesis rate stomatal conductance decreased Pi-starved conditions. total chlorophyll contents were increased P-deficient plants, owing to lack Pi molecules sustain functioning, particularly, Rubisco fructose-1,6-bisphosphatase function. dry biomass shoots, roots, P concentrations significantly reduced marketable effects cereal than legumes. To mitigate stress, plants activate alternative regulatory pathways, Pi-dependent glycolysis, mitochondrial respiration cytoplasm. Plants grown well-Pi supplementation drought stress exhibited higher shoots no-P treated ones. supply metals metal leaves for cadmium (Cd) lead (Pb), but could not prevent them from absorbing soils. detoxify enhance catalase ascorbate peroxidase activity prevents lipid peroxidation leaves.

The Chemistry of Stress: Understanding the ‘Cry for Help’ of Plant Roots

Metabolites, Год журнала: 2021, Номер 11(6), С. 357 - 357

Опубликована: Июнь 2, 2021

Plants are faced with various biotic and abiotic stresses during their life cycle. To withstand these stresses, plants have evolved adaptive strategies including the production of a wide array primary secondary metabolites. Some metabolites can direct defensive effects, while others act as chemical cues attracting beneficial (micro)organisms for protection. Similar to aboveground plant tissues, roots also appear "a cry help" response upon exposure stress, leading recruitment microorganisms help minimize damage caused by stress. Furthermore, emerging evidence indicates that microbial is, at least in part, mediated quantitative and/or qualitative changes root exudate composition. Both volatile water-soluble compounds been implicated important signals activation root-associated microbes. Here we provide an overview our current understanding belowground communication, particularly how stressed shape its protective microbiome.

Cover Crops for Sustainable Cropping Systems: A Review

Agriculture, Год журнала: 2022, Номер 12(12), С. 2076 - 2076

Опубликована: Дек. 3, 2022

Cover cropping is a promising and sustainable agronomic practice to ameliorate soil health crop performances in agro-ecosystems. Indeed, cover crops (CCs) may regulate several ecosystem services such as nutrient cycling, fertility, moderation of extreme meteorological events, pollination, climate water regulation; addition, CCs are also used forage have considerable effects on plant biodiversity. However, achieve the desired agro-ecosystems, should be carefully adopted by considering specie choice, period cultivation, termination method based site, farm, or purpose-specific. The main objective this manuscript analyze modern agriculture environmental how can support systems global food security. In it focuses incorporation into conventional help diversification assist mitigating systems.

Phosphorus Mobilization in Plant–Soil Environments and Inspired Strategies for Managing Phosphorus: A Review

Agronomy, Год журнала: 2022, Номер 12(10), С. 2539 - 2539

Опубликована: Окт. 17, 2022

Crop productivity and yield are adversely affected by the deficiency of P in agricultural soil. Phosphate fertilizers used at a large scale to improve crop yields globally. With rapid increase human population, food demands also increasing. To see that meet demands, farmers have continuously added phosphate their arable fields. As primary source inorganic phosphorous, rock is finite risk its being jeopardized foreseeable future high. Therefore, there dire need plant-available soil, using feasible, environmentally friendly technologies developed on basis further understanding dynamics between soil plants. This study systemically reviews mechanism uptake P-use efficiency plants under starvation conditions. The recent advances various strategies, especially imaging techniques, over period 2012–2021 for measurement identified. then examines how fulfill requirements from tissue-stored during starvation. Following this understanding, strategies increasing evaluated. Finally, an update novel carriers content provided.

Plant phosphorus‐use and ‐acquisition strategies in Amazonia

New Phytologist, Год журнала: 2022, Номер 234(4), С. 1126 - 1143

Опубликована: Янв. 21, 2022

In the tropical rainforest of Amazonia, phosphorus (P) is one main nutrients controlling forest dynamics, but its effects on future biomass carbon (C) storage under elevated atmospheric CO2 concentrations remain uncertain. Soils in vast areas Amazonia are P-impoverished, and little known about variation or plasticity plant P-use -acquisition strategies across space time, hampering accuracy projections vegetation models. Here, we synthesize current knowledge leaf P resorption, fine-root foraging, arbuscular mycorrhizal symbioses, root acid phosphatase organic exudation discuss how these vary with soil response to . We identify gaps suggest ways forward fill those gaps. Additionally, propose a conceptual framework for variations along gradients Amazonia. that soils intermediate high concentrations, at community level, investments primarily directed foraging via roots mycorrhizas, whereas low shift prioritize resorption mining phosphatases acids.
