Root and rhizosphere traits for enhanced water and nutrients uptake efficiency in dynamic environments

Frontiers in Plant Science, Год журнала: 2024, Номер 15

Опубликована: Июль 31, 2024

Modern agriculture's goal of improving crop resource acquisition efficiency relies on the intricate relationship between root system and soil. Root rhizosphere traits play a critical role in efficient use nutrients water, especially under dynamic environments. This review emphasizes holistic perspective, challenging conventional separation nutrient water uptake processes necessity for an integrated approach. Anticipating climate change-induced increase likelihood extreme weather events that result fluctuations soil moisture availability, study explores adaptive potential to mitigate stress. We emphasize significance characteristics enable crops rapidly respond varying availabilities (i.e. presence mobile zone) their accessibility possibility transport resources surface). These encompass example hairs, mucilage extracellular polymeric substance (EPS) exudation, rhizosheath formation expression transporters. Moreover, we recognize challenge balancing carbon investments, stress, where optimized must consider carbon-efficient strategies. To advance our understanding, calls well-designed field experiments, recognizing limitations controlled Non-destructive methods such as mini rhizotron assessments

Subsurface Drip Irrigation Combined with Ammonium Enhances Root Growth in Rice (Oryza sativa L.), Leading to Improved N Uptake and Higher Yield Formation

Plants, Год журнала: 2025, Номер 14(6), С. 891 - 891

Опубликована: Март 12, 2025

Coordinating the spatial distribution of crop roots with soil nutrients, along selecting appropriate types fertilizers, is an effective strategy to enhance root nutrient absorption and increase yield. In Xinjiang’s current surface drip irrigation practices for rice (Oryza sativa L.), premature leaf senescence N deficiency are common issues, resulting in decreased yields. This study investigated whether different forms under subsurface can modulate morphological strategies delay later growth stages, enhancing uptake yield formation. A field experiment compared effects positions (surface at surface, DI0; 10 cm depth, DI10) (urea N, UN; ammonium AN) four combination treatments (DI0-UN, DI0-AN, DI10-UN, DI10-AN) on morphology, aboveground growth, During grain-filling stage, total length (RL) number (RN) DI10-AN treatment were higher than other treatments. Root vitality increased by 23.24–133.72% during filling while decline rate 1.16–32.80%. The configuration parameters β superior those treatments, indicating that tend distribute deeper soil. reduced Malondialdehyde (MDA) levels Superoxide Dismutase (SOD) activity, thereby alleviating water stress leaves stages maintaining photosynthetic parameter values. significantly (14.37–52.88%) (13.32–46.31%).

Earlier snowmelt reduces the strength of carbon sink in montane meadows

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Апрель 15, 2025

Abstract Warming temperatures are changing winters, leading to earlier snowmelt. This shift can accelerate or extend the growing season, which in turn may affect various plant-mediated ecosystem functions. Despite its relevance carbon cycle, we still know little about how snowmelt impacts balance ecosystems over season. Most studies rely on interannual variability timing, making it difficult isolate effects from other confounding variables, e.g, temperature and moisture anomalies. To address this uncertainty, investigated advancing affects cycling of montane meadows. We experimentally advanced date by approximately nine days collected data every two weeks throughout including net exchange (NEE), gross primary productivity (GPP), respiration (ER), plant composition, shrub, graminoid, forb biomass. Early GPP was higher early plots, though effect decreased as season progressed. Our modeling cumulative NEE showed that reduced sink strength around 70%, likely due drier soils. Graminoid biomass 47% plots with snowmelt, but there no change total As winters warm occurs earlier, will However, soil during summer limit productivity, weakening overall altering

Rainfall-runoff nitrogen (N) pollution has emerged as the primary source of water contamination due to rapid urbanization. Green infrastructure (GI), representative measure, is widely used in controlling N runoff. However, there limited research on impact woody plants reduction GIs. Therefore, this study aimed investigate influence and relationship Sophora japonica (with tap root) Malus baccata fibrous removal Utilizing advanced root analysis software WinRHIZO (version 4.0b), a meticulous examination morphological traits plant roots was conducted. The findings unveiled striking contrast between systems two species: S. primarily boasts vertically oriented configuration, whereas M. baccata’s system characterized by an extensively lateral, or horizontal, growth pattern. Specifically, comparison japonica, horizontal demonstrated substantial superiority, with their total length measuring 10.95 times longer, surface area spanning 6.25 wider, cumulative volume being 3.93 greater. For comparing load rates runoff NH3-N, NO3-N, TN different morphologies’ GIs, GI had highest purification effect three pollutants, average pollutants reached 67.74%, 33.83%, 38.96%, respectively, which were 11.42%, 27.46%, 6.16% higher than those control. variance contribution rate vertical characteristics accounted for 86.47% rate. most crucial characteristic factor affecting load.

Опубликована: Июль 5, 2024

Allelopathic compounds released by invasive plants can directly affect neighbouring interfering with their germination and suppressing the growth of seedlings or adult plants. In this study, we investigated strength allelopathic effect three plants: Japanese knotweed (Fallopia japonica), Canadian goldenrod (Solidago canadensis) stinkwort (Dittrichia graveolens) on early Tartary buckwheat (Fagopyrum tatricum). All aqueous extracts significantly reduced seedlings, but had almost no seed germination. addition, obtained from a 2-fold serial dilution 10% extract D. graveolens inhibited in dose-dependent manner. The results showed that root length was more than shoot length, while remained largely unaffected.
