Published: Feb. 28, 2022

Continuous cropping obstacles have increasingly become an important phenomenon affecting crop yield and quality. Its harm includes the deterioration of soil basic physical chemical properties, changes microbial community structure, accumulation autotoxins, weakness plant growth, aggravation diseases pests. In this review, evolutionary trend structure driven by continuous was generalized, while drivers these summed up as destruction living environment competition within community. We introduced a microorganism proliferation working model with three basics vector, four corresponding effective measures to reshape were comprehensively expounded. According model, we also put forward optimization strategies existing measures. which, synthetic microbiology provides new solution for improving structure. Meanwhile, ensure survival reproduction microorganisms, it is necessary consider their space carbon sources in fully. This review provided comprehensive perspective understanding under conditions summary reshaping direction.

Trophic relationships between protists and bacteria and fungi drive the biogeography of rhizosphere soil microbial community and impact plant physiological and ecological functions

Microbiological Research, Journal Year: 2024, Volume and Issue: 280, P. 127603 - 127603

Published: Jan. 7, 2024

Rhizosphere microorganisms play a vital role in enhancing plant health, productivity, and the accumulation of secondary metabolites. Currently, there is limited understanding ecological processes that control assembly community. To address microbial interactions for functioning rhizosphere soil microbiota, we collected samples from Anisodus tanguticus on Tibetan Plateau spanning 1500 kilometers, sequenced bacteria, fungi, archaea, protist communities. We observed significant but weak distance-decay relationship communities soil. Our comprehensive analysis spatial, abiotic, biotic factors showed trophic relationships between protists bacteria fungi predominantly influenced alpha beta diversity bacterial, fungal, protistan communities, while abiotic had greater impact archaeal including pH, available phosphorus, total phosphorus mean annual temperature. Importantly, more influence physiological functions compared to individual microorganisms. Network analyses revealed occupy central position co-occurrence network crucial connector within this The addition increased stability networks. Overall, our findings indicate an important microbiota. Bacterial serve as link different kingdoms These help us fully harness beneficial plants achieve sustainable use biological resources.

Trophic interactions in soil micro‐food webs drive ecosystem multifunctionality along tree species richness

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(3)

Published: March 1, 2024

Abstract Rapid biodiversity losses under global climate change threaten forest ecosystem functions. However, our understanding of the patterns and drivers multiple functions across gradients remains equivocal. To address this important knowledge gap, we measured simultaneous responses (nutrient cycling, soil carbon stocks, organic matter decomposition, plant productivity) to a tree species richness gradient 1, 4, 8, 16, 32 in young subtropical forest. We found that had negligible effects on nutrient productivity, but stocks multifunctionality significantly increased with richness. Linear mixed‐effect models showed organisms, particularly arbuscular mycorrhizal fungi (AMF) nematodes, elicited greatest relative multifunctionality. Structural equation revealed indirect mediated by trophic interactions micro‐food webs. Specifically, significant negative effect gram‐positive bacteria nematode abundance (a top‐down effect), positive AMF biomass bottom‐up effect). Overall, study emphasizes significance multitrophic perspective elucidating biodiversity‐multifunctionality relationships highlights conservation functioning webs maintain

Protist feeding patterns and growth rate are related to their predatory impacts on soil bacterial communities

FEMS Microbiology Ecology, Journal Year: 2022, Volume and Issue: 98(6)

Published: May 5, 2022

Predatory protists are major consumers of soil micro-organisms. By selectively feeding on their prey, they can shape microbiome composition and functions. While different known to show diverging impacts, it remains impossible predict a priori the effect given species. Various protist traits including phylogenetic distance, growth rate volume have been previously linked predatory impact protists. Closely related protists, however, also showed distinct prey choices which could mirror specificity in dietary niche. We, therefore, aimed estimate niche breadth overlap eight isolates 20 bacterial species plate assays. To assess informative value suggested newly proposed (feeding-related) traits, we them impacts predation each protist-free community microcosm via 16S rRNA gene amplicon sequencing. We demonstrate that pattern vitro. Further, assayed patterns rates correlated well with observed structure communities. thus conclude vitro screening has potential inform specific selected

Abstract Protists occupy multiple trophic positions in soil food webs and significantly contribute to organic matter decomposition biogeochemical cycling. can ingest bacteria fungi as main sources while being subjected predation of invertebrates, but our understanding how bottom‐up top‐down regulations structure protists natural habitats is limited. Here, we disentangle the effects diversity settings across northern eastern Australia. Bacterial invertebrate were identified important drivers functional groups protists. Moreover, compositions protistan taxonomic better predicted by fungi, than invertebrates. There strong interconnections between organismic network analysis. Altogether, study provided new evidence that, control played an role shaping protist community structure, which be derived from feeding preferences on microbial prey, their intimate relationships functioning or environmental adaptation. Our findings advance knowledge about impacts different key communities, with implications for ecosystem functions services.
