Physical characteristics of rhizosphere are crucial for plant performance; and analyses rhizosheath, i.e. root-adhering soil, is a common tool in studies. Yet, despite numerous efforts, processes that lead to formation porosity gradients, as well their relationships with remain poorly understood. We used X-ray computed micro-tomography (uCT) examine distinguish between the effect direct root-induced changes vs. preferential root growth patterns on observed macroporosity gradients. also utilized 14C labeling evaluate rhizosheath relation rhizodeposition. The experiments were conducted intact soil inherent structure preserved sieved structureless soil. Rhizosphere was found be largely outcome preferences, while occurred at <0.1 mm distances from surface primarily soils. Rhizosheath linked roots actively compacting surrounding releasing carbon it, there no link destructively-sampled intactly uCT-observed rhizosphere. findings suggest root-soil interactions, rather than changes, drive porosity. development compensates low soil-root contact, however, traditionally sampled not representative actual

Roots and the associated soil directly affected by root activity, termed rhizosphere, have both been extensively studied recognized for their crucial role in functioning. The formation of rhizosphere is primarily driven effect roots on shaping physical structure soil, which turn has direct feedbacks interactions between physical, biological chemical processes. As a result, hot spot microbial cycling nutrients turnover organic matter. Despite pivotal controlling processes, we still lack quantitative description understanding interrelationships root-systems creation stabilization structure. We provide comprehensive review current knowledge novel insights into processes that drive rhizosphere. These are regulated multiple indirect pathways, involving growth, production rhizodeposits hairs, as well activity microorganisms fauna. Further, highlight may persist evolve after death to an extent currently largely unknown. Finally, identify five pertinent challenges should be addressed fully apprehend thus harness potential resilience plant-soil interactions. include refining structural assessment sampling rhizosheaths, examining in-situ bridging gap solid phase pore scale research. In our view, overcoming these obstacles can accomplished combining power imaging isotopic approaches, especially at field scale, encompassing diverse soils plant species. ultimate objective future research upscale conducting more experiments concert with modeling efforts, under umbrella collaborative interdisciplinary

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

Employing crop cultivars with low cadmium (Cd) accumulation and high yield is an effective strategy for the sustainable safe utilization of Cd-contaminated farmland. However, current understanding peanut cultivars, particularly under field conditions, limited. This study identified low-Cd their rhizosphere microbial characteristics in acidic alkaline fields moderate Cd contamination. The results indicated that LH11, FH1, LH14, YH9414 exhibited yield, kernel content reduced by 27.27% to 47.28% increased 9.27% 14.17% compared cultivar SLH. Among them, FH1 was validated achieve production two fields. A unique community formed recruitment diverse microbes, such as Alphaproteobacteria, Acidobacteria, Gemmatimonadetes, Chloroflexi, soil which might be associated immobilization promotion plant growth. Functional predictions further these findings, revealing enhanced functional pathways related proliferation, stabilization, detoxification. provides valuable germplasm resources agriculture Cd-polluted soils elucidates different conditions. These findings are important targeted management contaminated farmland ensuring food production.

Low-cadmium (Cd) accumulating wheat cultivars (LAWC-Cds) can effectively reduce the total Cd content in grains (Grain-Cd). Thirteen LAWC-Cds were planted three fields to study enrichment, transport, and accumulation patterns of LAWC-Cds. Compared with soil properties before planting, pH decreased, while diethylenetriaminepentaacetic acid extract, conductivity, organic matter increased at maturity. The enrichment capacity different organs decreased following order: root > leaf rachis stem glume grain. dynamics roots affected Grain-Cd, these factors negatively correlated. all showed strong negative correlations lengths first second internodes highly significant positive both per spike awn length. Structural equation modeling that had most direct effect (0.639) determining largest (0.744) influencing Grain-Cd. This is important for screening stable low Cd-accumulation characteristics.
