Abstract Plants and their symbionts, such as arbuscular mycorrhizal (AM) fungi, are increasingly subjected to various environmental stressors due climate change, including drought. As a response drought, plants generally allocate more biomass roots over shoots, thereby facilitating water uptake. However, whether this allocation shift is modulated by AM fungi remains unknown. Based on 5691 paired observations from 154 plant species, we conducted meta‐analysis evaluate how modulate the responses of growth (e.g., root‐to‐shoot ratio, R/S) We found that attenuate negative impact drought growth, production, photosynthetic performance resource (e.g. nutrient water) Accordingly, significantly increased R/S in non‐inoculated plants, but not symbiotic with established fungal symbioses. These results suggest promote stabilize through uptake under Our findings highlight crucial role enhancing resilience optimizing allocation. This knowledge opens avenues for sustainable agricultural practices leverage relationships adaptation.

ABSTRACT Most rice production is conducted in flooded (anaerobic) soil conditions, but aerobic cultivation presents several potential benefits: increased grain water use efficiency (gWUE), reduced methane emissions, and minimised loss of phosphorus (P). Arbuscular mycorrhizal (AM) fungi are more effective at colonising functioning under this rice‐AM association could increase both gWUE P acquisition (PAE). We used a precision irrigation platform to apply watering treatments (60% or 80% field capacity) throughout the experiment. Four commercial Australian varieties were grown with without inoculation Rhizophagus irregularis , addition fertiliser 10 25 mg kg –1 soil. Plants maturity (134–188 days after planting), which yield, plant use, gWUE, PAE determined. Overall, R. all four (by mean 14.4%), yield two varieties. Grain yields primarily constrained by low availability (mean 48.4% reduction), also limited Of four, Topaz showed greatest response AM fungal inoculation, qWUE PAE. There for efficiencies aerobically rice. However, extent these benefits depends on specific variety, highlights importance variety selection transitioning temperate regions enhancing resilience climate change.

Introduction Drought stress usually inhibits plant growth, which may increase the difficulty of greening slopes. Methods In this study, we systematically investigated effects arbuscular mycorrhizal (AM) fungi on growth and drought tolerance two species, Festuca elata Cassia glauca , in a vegetation concrete environment by exogenously inoculating AM setting three levels: well water, moderate severe drought.

Hydraulic redistribution (HR) is a critical ecological process whereby plant roots transfer water from wetter to drier soil layers, significantly impacting moisture dynamics and nutrient uptake. Yet comprehensive understanding of the mechanism triggering HR its influencing factors remains elusive. Here, we conducted systematic meta-analysis discuss influence conditions species characteristics on occurrence. The threshold ranges -1.80 -0.05 MPa, with hydraulic conductivity between 1.51 × 10-13 6.53 10-5 cm s-1 when occurs. influenced by various factors. Soil texture plays pivotal role, loamy soils promoting more effectively than sandy clay soils. Plant root structure occurrence, where prevalent in deep-rooted tree larger canal diameters dimorphic roots. Additionally, mycorrhizal fungi enhance expanding uptake area, reducing transport distances improving structure. However, adverse conditions, inadequate physiological regulatory capacity, or methodological limitations can hinder detection. findings highlight that likely occur there significant potential gradient, appropriate root-soil contact, low nocturnal transpiration. Plants replenish dry systems under drought increasing maintain normal functions. Our study identifies key HR, offering framework for future research aimed at resistance refining ecohydrological models.
