Plant–soil feedback under drought: does history shape the future?

Trends in Ecology & Evolution, Год журнала: 2023, Номер 38(8), С. 708 - 718

Plant–soil feedback (PSF) is widely recognised as a driver of plant community composition, but understanding its response to drought remains in infancy. Here, we provide conceptual framework for the role PSF, considering traits, severity, and historical precipitation over ecological evolutionary timescales. Comparing experimental studies where plants microbes do or not share history (through co-sourcing conditioning), hypothesise that with shared experience more positive PSF under subsequent drought. To reflect real-world responses drought, future need explicitly include plant–microbial co-occurrence potential co-adaptation consider experienced by both microbes.

Interplay of biotic and abiotic factors shapes tree seedling growth and root-associated microbial communities

Communications Biology, Год журнала: 2024, Номер 7(1)

Опубликована: Март 22, 2024

Abstract Root-associated microbes can alleviate plant abiotic stresses, thus potentially supporting adaptation to a changing climate or novel environments during range expansion. While change is extending species fundamental niches northward, the distribution and colonization of mutualists (e.g., arbuscular mycorrhizal fungi) pathogens may constrain growth regeneration. Yet, degree which biotic factors impact performance associated microbial communities at edge their remains unclear. Here, we use root microscopy, coupled with amplicon sequencing, study bacterial, fungal, root-associated from sugar maple seedlings distributed across two temperate-to-boreal elevational gradients in southern Québec, Canada. Our findings demonstrate that soil pH, Ca, distance trees are key drivers communities, overshadowing influence elevation. Interestingly, changes fungal community composition mediate an indirect effect pH on seedling growth, pattern consistent both sites. Overall, our highlight complex role shaping tree-microbe interactions, turn correlated growth. These have important ramifications for tree expansion response shifting climatic niches.

Arbuscular mycorrhiza: advances and retreats in our understanding of the ecological functioning of the mother of all root symbioses

Plant and Soil, Год журнала: 2023, Номер 489(1-2), С. 41 - 88

Опубликована: Май 2, 2023

Abstract Background Arbuscular mycorrhizal (AM) symbiosis has been referred to as the mother of all plant root symbioses it predated evolution roots. The AM research is a multidisciplinary field at intersection soil science, mycology, and botany. However, in recent decades nature properties soils, which develops functions, have received less attention than desired. Scope In this review we discuss number developments research. We particularly cover role acquisition phosphorus, nitrogen, heavy metals metalloids, well water by plants from soil; effects on nutritional stoichiometry carbon cycle; hyphosphere microbiome; so-called facultative plants; explanations for lack benefit; common networks; arbuscular ectomycorrhizal ecosystems. Conclusion reflect what previously described ‘dogmas’. conclude that these are fact generalisations supported multiple studies, while admitting there potentially geographical bias developed temperate boreal regions, other ecosystems might uncover greater diversity viable non-mycorrhizal strategies currently acknowledged. also note an increasing tendency overinterpret data, may lead stagnation some fields due experiments designed test mechanistic basis processes rather cumulating descriptive studies correlative evidences.

Plant-soil feedback: incorporating untested influential drivers and reconciling terminology

Plant and Soil, Год журнала: 2023, Номер unknown

Опубликована: Фев. 11, 2023

Abstract Background Plants condition the soil in which they grow, thereby altering performance of subsequent plants growing this soil. This phenomenon, known as plant-soil feedback (PSF), has garnered increasing interest. Experiments are moving from single species pairings glasshouse to community-level field trials. Consequently, our knowledge role PSF plays shaping ecosystem functions advanced. However, gaps remain. Scope Here, we explore intrinsic and extrinsic abiotic biotic drivers such maternal effects, plant functional traits, self-DNA, plant-plant competition, herbivory, interactions between organisms, temperature, drought, flooding, greenhouse gases, (micro)nutrients, plant-litter-soil priority effects. These have begun feature experiments, mechanistic understanding PSF. Nonetheless, many these topics received insufficient coverage determine general principles across larger temporal spatial scales. Further, conflicting terminology excluded studies reviews meta-analyses. We review terms sickness, Janzen-Connell hypothesis, soil-related invasive work, legacies, allelopathy succession that overlap with but generally not named such. Conclusion Holistic experimental designs consider continual reciprocal environment, soil, well unification terminologies necessary if realise full potential for steering processes. compile outstanding questions related research emphasis aforementioned suggest ways incorporate them into future order advance ecology.

Plant-associated microorganisms may be invisible to the naked eye, yet they play a key role in future sustainability of terrestrial ecosystems – from arable lands rainforests, through tundra and taiga deserts. It is now widely recognized that climate change dramatically impacts plant performance physiology.
