Abstract Motivation Trait data are fundamental to the quantitative description of plant form and function. Although root traits capture key dimensions related responses changing environmental conditions effects on ecosystem processes, they have rarely been included in large‐scale comparative studies global models. For instance, remain absent from nearly all that define spectrum Thus, overcome conceptual methodological roadblocks preventing a widespread integration trait into analyses we created Global Root (GRooT) Database. GRooT provides ready‐to‐use by combining expertise ecologists with mobilization curation. Specifically, (a) determined set core relevant function based an assessment experts, (b) maximized species coverage through standardization within among traits, (c) implemented quality checks.

Root functional traits explain root exudation rate and composition across a range of grassland species

Journal of Ecology, Год журнала: 2021, Номер 110(1), С. 21 - 33

Опубликована: Фев. 20, 2021

Abstract Plant root exudation is a crucial means through which plants communicate with soil microbes and influence rhizosphere processes. Exudation can also underlie ecosystem response to changing environmental conditions. Different plant species vary in their exudate quantity quality, but our understanding of the characteristics that drive these differences fragmentary. We hypothesised exudates would be under phylogenetic control fit within an exploitative nutrient uptake strategy, specifically high rates link traits indicative growth. collected from grown field soil, as well leachates entire plant–soil system, assess both quality exudates, interaction metabolome, across 18 common grassland species. found varied functional group were trait dependent. Particularly, diameter, tissue density nitrogen content explained much variation along phylogeny. Specific rate was highest forbs negatively correlated density, conservative resource‐use positively associated microbial collaboration resource ‘outsourcing’. Synthesis . provide novel insight into species‐specific identify might differences. Our results show fits, although not entirely, current models economic space, strong positive relationships outsourcing like diameter. Determining role key facet resource‐outsourcing strategy necessitates further research fundamental controls on particularly during change.

Deciphering the role of specialist and generalist plant–microbial interactions as drivers of plant–soil feedback

New Phytologist, Год журнала: 2022, Номер 234(6), С. 1929 - 1944

Опубликована: Март 26, 2022

Feedback between plants and soil microbial communities can be a powerful driver of vegetation dynamics. Plants elicit changes in the microbiome that either promote or suppress conspecifics at same location, thereby regulating population density-dependence species co-existence. Such effects are often attributed to accumulation host-specific antagonistic beneficial microbiota rhizosphere. However, identity host-specificity taxa involved rarely empirically assessed. Here we review evidence for plant-associated microbes propose specific plant-soil feedbacks also driven by generalists. We outline potential mechanisms which generalist pathogens, mutualists decomposers generate differential on plant hosts synthesize existing predict these as function investments into defence, dispersal. Importantly, capacity drive depends not only traits individual but phylogenetic functional diversity communities. Identifying factors specialization generalism plant-microbial interactions modulate impact performance will advance our understanding underlying feedback ways it contributes

The rhizosphere microbiome, which is shaped by host genotypes, root exudates, and plant domestication, crucial for sustaining agricultural growth. Despite its importance, how domestication builds up specific microbiomes metabolic functions, as well the importance of these affected rhizobiomes relevant exudates in maintaining growth, not understood. Here, we firstly investigated bacterial fungal communities wild accessions tetraploid wheat using amplicon sequencing (16S ITS) after 9 years process at main production sites China. We then explored ecological roles exudation shaping microbiome functions integrating metagenomics genomics approaches. Furthermore, established evident linkages between morphology traits keystone taxa based on microbial culture inoculation experiments.Our results suggested that were co-shaped both genotypes status. genomes contributed more variation diversity composition than communities, whereas status exerted much stronger influences communities. In terms interkingdom association networks, destabilized network depleted abundance taxa. Moreover, found shifted from slow growing fungi dominated to fast bacteria dominated, thereby resulting a shift fungi-dominated membership with enrichment carbon fixation genes bacteria-dominated degradation genes. Metagenomics analyses further indicated cultivars possess higher function domesticated cultivars. Notably, cultivar able harness microorganism carrying N transformation (i.e., nitrification, denitrification) P mineralization pathway, inorganic fixation, organic ammonification, solubilization are recruited releasing wheat.

Plant phosphorus‐use and ‐acquisition strategies in Amazonia

New Phytologist, Год журнала: 2022, Номер 234(4), С. 1126 - 1143

Опубликована: Янв. 21, 2022

In the tropical rainforest of Amazonia, phosphorus (P) is one main nutrients controlling forest dynamics, but its effects on future biomass carbon (C) storage under elevated atmospheric CO2 concentrations remain uncertain. Soils in vast areas Amazonia are P-impoverished, and little known about variation or plasticity plant P-use -acquisition strategies across space time, hampering accuracy projections vegetation models. Here, we synthesize current knowledge leaf P resorption, fine-root foraging, arbuscular mycorrhizal symbioses, root acid phosphatase organic exudation discuss how these vary with soil response to . We identify gaps suggest ways forward fill those gaps. Additionally, propose a conceptual framework for variations along gradients Amazonia. that soils intermediate high concentrations, at community level, investments primarily directed foraging via roots mycorrhizas, whereas low shift prioritize resorption mining phosphatases acids.
