1. Impact of power line corridors on carbon stocks of upland forests in eastern Canada.
PMID:日期:2026-08-18Hydroelectricity is considered a renewable energy source with low greenhouse gas emissions. However, little attention has been given to the impact of the construction and maintenance of power line corridors on soil and vegetation. This study assessed the effect of power line corridors on terrestrial carbon pools in upland forests across a 750-km gradient from deciduous forests to open-canopy taiga in Quebec (Canada). Quantification of ecosystem carbon pools (live biomass, dead organic matter and soil) was carried out using transects of plots located in: i) the power line corridor, ii) the forest located at 20 m from the corridor edge (forest edge), and iii) the forest located at 60 m from the corridor (interior forest, considered as a control). Ecosystem carbon stocks were significantly lower in the corridors, with reductions of 36-133 Mg of C ha compared with interior forests. Yet, corridors still stored substantial carbon (average of 108.5 ± 13.7 Mg of C ha). While biomass of trees and shrubs was significantly reduced in the corridor compared with interior and edge forests, total soil carbon stocks (which varied from 80.11 to 169.91 Mg of C ha across bioclimatic domains) were similar between corridors and forests. We also observed similar carbon stocks between edge and interior forests, suggesting that the influence of power line corridors is not noticeable at 20 m and beyond in adjacent forest ecosystems. Our study improves the quantification of carbon storage across forested landscapes and the GHG footprint of hydroelectricity.

2. Digging for meaningful connections: associations between root phenotypes and rhizosphere microbial diversity in maize.
PMID:日期:2026-07-11Drought threatens food security globally. Adaptive root phenotypes and microbiomes can improve maize ( L.) water uptake and tolerance to drought. However, synergisms between root phenotypes and microbiomes remain underexplored. We aimed to investigate the association between varying root phenotypes and rhizosphere microbiomes under field-scale drought. We grew 22 maize inbred lines in the field under optimal water availability and drought imposed by excluding rain with rainout shelters. We quantified grain yield and measured root architectural and anatomical phenotypes on root crown and cross-section images obtained by laser ablation tomography, respectively. We characterized rhizosphere prokaryotic and fungal communities with DNA metabarcoding of ribosomal markers. Rhizosphere microbial diversity predominantly associated with root anatomy rather than root architecture. Cortical parenchyma wall width explained 13.1% of the variance of the prokaryotic β-diversity and correlated with grain yield under control conditions. Under the same conditions, number of cortical cell files and metaxylem vessels explained 1.4%-2.1% of the variance of prokaryotic and fungal β-diversities. No effect of the root phenotypes was observed under drought. We found 248 significant correlations between microbial taxa abundances and root anatomical phenotypes, especially cortex-related phenotypes such as number of cell files and living cortical area. Overall, a greater number of correlations was found under control conditions. We identified root phenotypes explaining a small but significant percentage of the variance of the microbial β-diversity, mostly under optimal water availability. We showed that especially root anatomy is associated with rhizosphere microbial diversity in field-grown maize.

3. Alpine dwarf shrubs on green roofs: species-specific physiological responses to substrate depth and drought intensity.
PMID:日期:2026-07-09Green roofs can enhance urban biodiversity when local, functionally diverse species are used. However, extreme roof conditions require species selection based on plant eco-physiological characteristics. This study evaluated the performance of four Alpine dwarf shrubs (, , , ) in green roof plots with 10 and 30 cm substrate under natural conditions (temperate climate) and compared it with the drought-tolerant shrub as a reference. Seasonal and daily variations in leaf temperature, water potential, and gas exchange were recorded during humid and dry periods to assess how substrate depth modulates plant-soil interactions. More favourable water availability and temperature with 30 cm substrate reduced drought stress and increased stomatal conductance, photosynthesis, and biomass in all shrubs compared to 10 cm substrate. However, species responded differently to substrate depth and drought intensity, with and performing best: the former remained above its hydraulic vulnerability threshold (Ψ) in both plots, and the latter with 30 cm substrate. Despite strict stomatal control, and exceeded their Ψ during drought in the 10 cm plot and experienced dieback. surpassed all Alpine species by achieving the highest gas exchange, growth and favourable water status in both substrates. Alpine dwarf shrubs can broaden the species for temperate green roofs, but some may experience drought-induced dieback with shallow substrate. Alternating deep and shallow substrate patches may be a cost-efficient strategy to improve shrub survival and account for species-specific limitations.

4. Environmental regulation of root growth angle in cereal crops.
PMID:日期:2026-04-22In recent years, the root system has emerged as a critical determinant of crop resilience and productivity under soil-related environmental stresses. Among root architectural traits, the root angle is particularly important because it shapes the depth and spatial distribution of roots, thereby influencing access to water and nutrients. A steeper angle can promote deeper soil exploration, whereas a shallower angle can improve topsoil foraging; each can confer advantages under specific stress conditions, including drought, flooding, salinity, and nutrient deficiency. This review explores the ecological relevance of the root angle, illustrated by adaptations observed in cereal crops across Australia, a continent characterized by diverse climatic and edaphic conditions. We then review the current understanding of how crop plants adjust root angle in response to water-related stresses (drought, flooding, osmotic and salinity) and nutrient (nitrate and phosphate) deficiency on root system and molecular level. We examine the underlying mechanisms and physiological responses, highlighting the roles of key hormonal pathways, particularly auxin, abscisic acid and ethylene and explore how cell wall mechanics potentially acts as a converging point for developmental and environmental signals to fi ne-tune root angle. Root angle is emerging as a critical trait for improving crop resilience and productivity under increasingly variable environmental conditions, and its ecological relevance, genetic variability, and responsiveness to environmental cues underscore its potential as a breeding target. Despite these insights, major knowledge gaps remain, particularly in understanding how multiple tropic responses coordinate under combined stresses and how these responses vary across root classes.

5. Root decomposition affects soil hydraulic properties in four contrasting herbaceous species.
PMID:日期:2026-02-16To optimise soil conditions for agriculture and engineering, we must better understand how root growth and decomposition affect soil hydraulic properties. This paper investigates soil hydraulic properties down soil columns containing grass, forb, and legume species before and after root decomposition. Contrasting species (2 grasses, 1 forb, 1 legume) were grown within repacked soil columns. These soil columns were divided horizontally into 60 mm cores and hydraulic conductivity ( ) was measured both before and after 7-month incubation of cores at either 5 °C or in a heated glasshouse (18-25 °C). Water sorptivity, hydrophobicity and hardness were measured in root-channel walls after decomposition in cores divided longitudinally. Soil water-release characteristics were measured in small cores sampled down the soil profile. Vegetated soil averaged up to 5.6-fold greater than fallow soils, varying greatly between species. decreased rapidly down the columns in fallow soil, whilst and soils had more uniform with depth. The soil of root-channel walls showed distinct sorptivity and hydrophobicity compared to control bulk-soil. Appropriate species choice can increase . Roots and their decomposition greatly affect these soil physical properties down the profile, influencing water dynamics in plant communities and soil-mediated ecosystem services.

6. Caterpillar-induced plant-soil feedback affects resistance in wild and cultivated cabbage.
6. 卡特彼勒诱导的植物-土壤反馈影响野生和栽培白菜的抗性PMID:日期:2026-02-11Aboveground insect herbivory can change the plant rhizosphere and modulate the composition of the soil microbiome. However, it is unclear to what extent these changes in the rhizosphere affect plant resistance to above-ground herbivorous insects, and how these plant-soil feedback (PSF) mechanisms are shaped. Here, we investigated whether herbivore-induced changes in the rhizosphere increase resistance against caterpillars in cabbage, , and how intraspecific variation of the host plant, herbivory intensity, and soil type affect PSF outcomes. PSF experiments with rhizosphere-soil transfer were performed for a wild and cultivated , with different densities of the caterpillar , and different soil types. We found that caterpillar-induced soil conditioning affected the performance of feeding on the shoot, depending on both intraspecific variation of the host plant and the intensity and duration of herbivory. On wild cabbage, caterpillar-induced PSF positively affected plant resistance to , which needed more than two weeks to become detectable. In contrast, in cultivated cabbage, caterpillar-induced PSF had a neutral to negative effect on plant resistance and did not differ between soil types. The observed negative PSF effect was associated with downregulation of genes involved in jasmonic acid biosynthesis and downstream signalling. Overall, we found that natural variation within one plant species can, depending on intensity and duration of herbivory, result in opposite PSF effects with consequences for jasmonic acid-mediated defences.

7. Comparative assessment of root exudation in maize: Influence of experimental setup, growth conditions and root hairs.
PMID:日期:2026-02-05A major challenge in root exudation research is obtaining exudates samples that accurately reflect the exudation processes under natural soil growth conditions. Both growth environment and experimental setup can significantly influence root exudation dynamics. This study investigated how different experimental systems and growth conditions affect carbon exudation in maize ( L.) roots and whether these factors could influence the detection of genotypic differences between the wild type (B73) and its hairless mutant, Maize plants were grown under various experimental conditions, including soil-based and hydroponic systems. Root exudates were collected using a combination of traditional and innovative sampling approaches. Carbon exudation rates were compared across experimental setups and genotypes. Laboratory results were further compared with data from a separate field experiment. Exudation rates obtained from soil-based laboratory experiments were comparable to those observed in the field under similar growth temperatures. The contribution of root hairs to total carbon exudation was negligible compared to the effect of growth conditions and experimental setup. Large differences in root biomass introduced bias into exudation measurements, particularly when root to sampling volume ratio (RSVR) varied substantially. Experimental setup and environmental conditions have a strong influence on root exudation measurement. Soil-based laboratory systems that closely replicate field conditions, particularly temperature, can serve as reliable proxies for field experiments, providing ecologically meaningful data. Maintaining a consistent RSVR is also essential for obtaining accurate and comparable results. These findings offer important methodological guidance for reliably quantifying root carbon exudation in maize.

8. Phosphorus and base cations drive contrasting root dynamics in a central Amazon forest.
PMID:日期:2026-02-02In highly weathered soils of central Amazonia, where nutrients such as phosphorus (P) and base cations are scarce, fertilization experiments have demonstrated above- and belowground effects on total net primary productivity (NPP). This study examined how fine root stocks and turnover responded to added nutrients over a two-year period. We predicted that adding a limiting nutrient would decrease fine root stocks and increase turnover, with the strongest effects from P, followed by base cations, and no response to N. Fine roots (< 2 mm diameter) were sampled from the 0-30 cm soil layer in a low-fertility primary forest in central Amazon subjected to a large-scale factorial experiment adding P, base cations, and N over two years. Fine root turnover was calculated as the ratio between fine root productivity, measured with in-growth cores, and fine root stock. Fine root stocks remained unchanged with nutrient addition. However, P increased root turnover by 23% and 48% in the first and second years, respectively, while base cations addition reduced turnover by 24% in year two. N had no significant effect, though a trend toward reduced turnover was observed in the second year. The results of this study show that fine root standing stock and turnover in the central Amazon are regulated by soil nutrient availability, especially P and base cations. The contrasting responses observed suggest distinct belowground resource-use strategies for different nutrients, shaped by the nutrient specific mobility in the soil and physiological role in the plant.

9. Drought increases root and rhizodeposition carbon inputs into soils.
PMID:日期:2026-01-12Increasing droughts affect crop yield and health. Plants can respond to drought by adapting their root biomass, root morphology, and quality and quantity of rhizodeposition to improve water and nutrient uptake. Besides droughts, agricultural management influences roots and rhizodeposition; however, it is not well studied how agricultural management can affect the response of roots and rhizodeposition to drought. A semi-continuous CO isotope labelling experiment was performed in a long-term field experiment comparing biodynamic, mixed conventional, and mineral conventional cropping systems. Rainout shelters were installed to induce drought. Root, net rhizodeposition, and the rhizosphere microbiome were determined at ripening of wheat. Drought enhanced the total root carbon mainly through the increase of fine roots. Fine root carbon under drought was primarily enhanced in the mixed conventional and biodynamic cropping system, both receiving farmyard manure, whereas no increase was measured in the mineral fertilized conventional system. Net rhizodeposition carbon was enhanced in all cropping systems under drought, particularly in the first 0.25 m. While some plant-growth-promoting genera such as and showed relative increases under drought, other plant growth-promoting genera often involved in nitrogen fixation such as and were decreased. This field trial suggests that drought increases total belowground carbon input via fine root and net rhizodeposition carbon inputs. Since fine root carbon increased under drought in cropping systems with farmyard manure, adding manure under future drought periods could be advantageous to increase soil carbon inputs and improve nutrient foraging.

10. Early belowground interactions in lupin-wheat intercropping assessed by a simple root phenotyping approach.
PMID:日期:2025-07-14Legume-cereal intercropping is a common strategy to enhance agricultural sustainability. Many plant-plant interactions occur in the underground but remain poorly understood due to methodological challenges. In the current study, we developed an indoor rhizobox-based simple and rapid root phenotyping approach to study early interactions between roots of white lupin seedlings cultivated as a sole crop or in intercropping with bread wheat. A rhizobox-based root phenotyping approach assessed the belowground structure of white lupin in the two conditions during early growth stages. The method focused on spatial root metrics and a rapid graphic indicator of root overlap between neighbour plants, termed Root Merge (RM) index. Root traits that could promote facilitative processes were also recorded. Lupin modified its root architecture spatially in response to intercropping rather than simply altering total root production. The RM index clearly separated the two lupin cropping systems. Lupin in pure stand showed an avoidance behaviour between neighbours (RM = 0.17) indicating spatial compartmentalization, whereas in intercropping large lupin-wheat root intermingling was evident (RM = 0.69), suggesting mechanisms for nutrient-availability facilitation. Lupin aboveground and belowground growth was not inhibited by the great spatial soil exploration of wheat in intercropping. Lupin nodulation significantly increased in intercropping compared to pure stand, highlighting facilitative interaction through enhanced biological nitrogen fixation. The root visual parameters proved to be useful indicators of phenotypic plasticity in response to intercropping. The method could be easily extended to other legume-cereal combinations or to intercropping involving other plant types.
