Soil protists: a fertile frontier in soil biology research

FEMS Microbiology Reviews, Journal Year: 2018, Volume and Issue: 42(3), P. 293 - 323

Protists include all eukaryotes except plants, fungi and animals. They are an essential, yet often forgotten, component of the soil microbiome. Method developments have now furthered our understanding real taxonomic functional diversity protists. occupy key roles in microbial foodwebs as consumers bacteria, other small eukaryotes. As parasites animals even larger protists, they regulate populations shape communities. Pathogenic forms play a major role public health issues human parasites, or act agricultural pests. Predatory protists release nutrients enhancing plant growth. Soil importance for eukaryotic evolution biogeography. also useful applied research bioindicators quality, models ecotoxicology potential biofertilizers biocontrol agents. In this review, we provide overview enormous morphological, taxonomical discuss current challenges opportunities protistology. Research biology would clearly benefit from incorporating more protistology alongside study

High Microbial Diversity Promotes Soil Ecosystem Functioning

Applied and Environmental Microbiology, Journal Year: 2018, Volume and Issue: 84(9)

Published: Feb. 19, 2018

ABSTRACT In soil, the link between microbial diversity and carbon transformations is challenged by concept of functional redundancy. Here, we hypothesized that redundancy may decrease with increasing source recalcitrance coupling C cycling change accordingly. We manipulated to examine how affects decomposition easily degradable (i.e., allochthonous plant residues) versus recalcitrant autochthonous organic matter) sources. found a in (i) affected both sources, thereby reducing global CO 2 emission up 40%, (ii) shaped toward preferential most Our results also revealed significance effect increases nutrient availability. Altogether, these findings show soil be more vulnerable changes than expected from previous studies, particularly ecosystems exposed inputs. Thus, concern about preservation highly relevant current global-change context assumed impact biodiversity pulse inputs residues rhizodeposits into soil. IMPORTANCE With hundreds thousands taxa per gram dominates biodiversity. While numerous studies have established communities respond rapidly environmental changes, relationship functioning remains controversial. Using well-controlled laboratory approach, provide empirical evidence high for matter decomposition, major process on which rely many ecosystem services provided ecosystem.

Controls and Adaptive Management of Nitrification in Agricultural Soils

Frontiers in Microbiology, Journal Year: 2019, Volume and Issue: 10

Published: Aug. 30, 2019

Agriculture is responsible for over half of the input reactive nitrogen (N) to terrestrial systems; however improving N availability remains primary management technique increase crop yields in most regions. In majority agricultural soils, ammonium rapidly converted nitrate by nitrification, which increases mobility through soil matrix, strongly influencing retention system. Decreasing nitrification desirable decrease losses and fertilizer use efficiency. We review controlling factors on rate extent soils from temperate regions including substrate supply, environmental conditions, abundance diversity nitrifiers plant microbial interactions with nitrifiers. Approaches include those that control inhibit directly. Strategies timing fertilization coincide rapid update, formulation fertilizers slow release or inhibitors, keeping growing continuously assimilate N, increasing assimilation (immobilization). Another effective strategy directly either synthetic biological inhibitors. Commercial inhibitors are but their complicated a changing climate organic requirements. The nitrifying organisms plants microbes producing promising approach just beginning be critically examined. Climate smart agriculture will need carefully consider optimized seasonal these strategies remain tools.

Nematode grazing promotes bacterial community dynamics in soil at the aggregate level

The ISME Journal, Journal Year: 2017, Volume and Issue: 11(12), P. 2705 - 2717

Published: July 25, 2017

Abstract Nematode predation has important roles in determining bacterial community composition and dynamics, but the extent of effects remains largely rudimentary, particularly natural environment settings. Here, we investigated complex microbial–microfaunal interactions rhizosphere maize grown red soils, which were derived from four long-term fertilization regimes. Root-free soil samples separated into three aggregate fractions whereby abundance examined for nematode total communities. A functional group alkaline phosphomonoesterase (ALP) producing bacteria was included to test hypothesis that grazing may significantly affect specific bacteria-mediated ecological functions, is, organic phosphate cycling soil. Results correlation analysis, structural equation modeling interaction networks combined with laboratory microcosm experiments consistently indicated bacterivorous nematodes enhanced diversity, bacterivores positively correlated biomass, including ALP-producing abundance. Significantly, such more pronounced large macroaggregates than microaggregates. There a positive between most dominant Protorhabditis keystone ‘species’ Mesorhizobium. Taken together, these findings implicate stimulating dynamics spatially dependent manner.
