Soil microbiome indicators can predict crop growth response to large-scale inoculation with arbuscular mycorrhizal fungi

Nature Microbiology, Год журнала: 2023, Номер 8(12), С. 2277 - 2289

Опубликована: Ноя. 29, 2023

Alternative solutions to mineral fertilizers and pesticides that reduce the environmental impact of agriculture are urgently needed. Arbuscular mycorrhizal fungi (AMF) can enhance plant nutrient uptake stress; yet, large-scale field inoculation trials with AMF missing, so far, results remain unpredictable. We conducted on-farm experiments in 54 fields Switzerland quantified effects on maize growth. Growth response was highly variable, ranging from -12% +40%. With few soil parameters mainly microbiome indicators, we could successfully predict 86% variation growth inoculation. The abundance pathogenic fungi, rather than availability, best predicted (33%) success. Our indicate indicators offer a sustainable biotechnological perspective success at beginning growing season. This predictability increases profitability engineering as tool for agricultural management.

Every organism on the earth maintains some kind of interaction with its neighbours. As plants are sessile, they sense varied above-ground and below-ground environmental stimuli decipher these dialogues to microbes neighbouring via root exudates as chemical signals resulting in modulation rhizospheric microbial community. The composition depends upon host genotype, cues, other biotic factors. Crosstalk agents such herbivores, microbes, can change plant exudate composition, which may permit either positive or negative interactions generate a battlefield rhizosphere. Compatible utilize carbon sources their organic nutrients show robust co-evolutionary changes changing circumstances. In this review, we have mainly focused different factors responsible for synthesis alternative leading rhizosphere microbiota. Understanding stress-induced community help us devise strategies engineering microbiomes enhance adaptive capabilities stressful environment.
