The impact of multifactorial stress combination on plants, crops, and ecosystems: how should we prepare for what comes next?

The complexity of environmental conditions encountered by plants in the field, or nature, is gradually increasing due to anthropogenic activities that promote global warming, climate change, and increased levels pollutants. While past it seemed sufficient study how acclimate one even two different stresses affecting them simultaneously, complex developing on our planet necessitate a new approach studying stress plants: Acclimation multiple occurring concurrently consecutively (termed, multifactorial combination [MFSC]). In an initial plant response MFSC, conducted with Arabidopsis thaliana seedlings subjected MFSC six abiotic stresses, was found increase number simultaneously impacting plant, growth survival declined, if effects each involved such minimal insignificant. three recent studies, crop plants, have similar commercial rice cultivar, maize hybrid, tomato, soybean, causing significant reductions growth, biomass, physiological parameters, and/or yield traits. As are worsening, as well becoming more complex, addressing its agriculture ecosystems worldwide becomes high priority. this review, we address crops, agriculture, worldwide, highlight potential avenues enhance resilience crops MFSC.

Climate change-associated multifactorial stress combination: A present challenge for our ecosystems

Journal of Plant Physiology, Год журнала: 2022, Номер 276, С. 153764 - 153764

Humans negatively influence Earth ecosystems and biodiversity causing global warming, climate change as well man-made pollution. Recently, the number of different stress factors have increased, when impacting simultaneously, multiple conditions cause dramatic declines in plant ecosystem health. Although much is known about how plants are affected by each individual stress, recent research efforts diverted into these biological systems respond to several applied together. Studies such "multifactorial combination" concept reported a severe decrease survival microbiome along increasing consistent directional trend. In addition, results concert with studies microbiota natural imposed change. Therefore, all this evidence should serve an important warning order pollutants, create strategies deal increase tolerance stressful combination. Here we review focused on impact abiotic stresses plants, agrosystems including forests microecosystems. mitigate discussed.

The microbial communities inhabiting urban soils determine the functioning of these soils, in regards to their ability cycle nutrients and support plant communities. In an increasingly urbanized world properties are utmost importance, responsible worthy exploration. We used 53 grassland sites spread across Berlin describe explain impacts urbanity other environmental parameters upon diversity community composition four groups. These groups were (i) Fungi, with a separate dataset for (ii) Glomeromycota, (iii) Bacteria, (iv) protist phylum Cercozoa. found that had distinct on fungal richness, which tended increase. Geographic distance between soil chemistry, addition urbanity, drove composition, site connectivity being important Glomeromycotan communities, potentially due host Our findings suggest many species well adapted as supported by increase far more common result than reverse. However, we also distinctly distributions operational taxonomic unit (OTU)s from same species, shedding doubt reliability indicator use taxonomy draw conclusion functionality. observational study employed extensive set gradient, region German capital, produce rich dataset; such it can serve blueprint investigations.

Responses of the arbuscular mycorrhizal fungi community to warming coupled with increased drought in an arid desert region

Geoderma, Год журнала: 2023, Номер 441, С. 116744 - 116744

Warming coupled with precipitation changes induced by climate change profoundly affect desert ecosystem functions in global drylands. Arbuscular mycorrhizal fungi (AMF) play a crucial role such ecosystems regulating energy and nutrient exchange. However, little is known about how AMF communities respond to warming reduced (W + RP). We evaluated the impacts of 0.5 °C 1.5 increase temperature 5 % 8 reductions total annual (0.5 W RP, RP) on main ecological processes structuring community assemblies rhizosphere soil typical winter plants Tengger Desert, northwest China. The results showed that could significantly alter composition, abundance, diversity communities. Both biomass increased RP treatment but decreased treatment. root colonization rate specific length, indicating trade-off between fine roots their symbiotic AMF. was phylogenetically random appeared clustered treatment, implying more pronounced can promote deterministic assembly community. provide conceptual framework for comprehending mechanisms underlying effects communities, incorporating biological geochemical processes. Overall, findings this study suggest abundance driving assemblages differently compared less intensive precipitation. Importantly, higher reduction plant dependence resulted stronger environmental filtration reducing water content.

Pushing the limits of C₃ intrinsic water use efficiency in Mediterranean semiarid steppes: Responses of a drought‐avoider perennial grass to climate aridification

Abstract Intrinsic water use efficiency (WUEi) reflects the trade‐off between photosynthetic carbon gain and loss through stomatal conductance is key for understanding dryland plant responses to climate change. Stipa tenacissima a perennial tussock C 3 grass with an opportunistic, drought‐avoiding strategy that dominates arid semiarid steppes across western Mediterranean region. However, its ecophysiological aridification woody shrub encroachment, major land‐use change in drylands worldwide, are not well‐understood. We investigated variations leaf stable isotopes (δ 18 O, δ 13 C, 15 N), nutrient concentrations (N, P, K), culm content isotopic composition 2 H) of paired pure‐grass shrub‐encroached S. along 350 km aridity gradient Spain (10 sites, 160 individuals). Culm revealed shallow‐rooted depends heavily on recent rainwater uptake, which may render it vulnerable increasingly irregular rainfall combined faster topsoil drying under warming aridification. With increasing aridity, enhanced leaf‐level WUE i more stringent regulation flux assimilation (higher O), reaching exceptionally high values (−23‰ −21‰) at most steppes. Foliar N concentration was remarkably low sites regardless evidencing severe co‐limitation photosynthesis productivity. Shrub encroachment decreased P K but did affect status. Perennial cover markedly both declining winter suggesting population‐level rather than individual‐level these changes. The fundamental physiological constraints metabolism foliar hamper ability other drought‐avoider species shallow roots achieve further adaptive improvements climatic stress.
