Summary Harnessing plant‐associated microbiomes offers an invaluable strategy to help agricultural production become more sustainable while also meeting growing demands for food, feed and fiber. A plethora of interconnected interactions among the host, environment microbes, occurring both above below ground, drive recognition, recruitment colonization resulting in activation downstream host responses functionality. Dissecting these complex by integrating multiomic approaches, high‐throughput culturing, computational synthetic biology advances is providing deeper understanding structure function native microbial communities. Such insights are paving way towards development products as well engineered with communities capable delivering agronomic solutions. While there a market microbial‐based solutions improve crop productivity, challenges commercialization remain. The continued translation microbiome knowledge into real‐world scenarios will require concerted transdisciplinary research, cross‐training next generation scientists, targeted educational efforts prime growers general public successful adoption innovative technologies.

Pinpointing secondary metabolites that shape the composition and function of the plant microbiome

Journal of Experimental Botany, Год журнала: 2020, Номер 72(1), С. 57 - 69

Опубликована: Сен. 10, 2020

Abstract One of the major questions in contemporary plant science involves determining functional mechanisms that plants use to shape their microbiome. Plants produce a plethora chemically diverse secondary metabolites, many which exert bioactive effects on microorganisms. Several recent publications have unequivocally shown metabolites affect microbiome composition and function. These studies pinpointed can be influenced by set molecules, including: coumarins, glucosinolates, benzoxazinoids, camalexin, triterpenes. In this review, we summarize role shaping microbiome, highlighting literature. A body knowledge is now emerging links specific with distinct microbial responses, mediated via defined biochemical mechanisms. There significant potential boost agricultural sustainability targeted enhancement beneficial traits, here argue newly discovered between root chemistry could provide new tools for rationally manipulating

Climate change and ensuring food security for an exponentially growing global human population are the greatest challenges future agriculture. Improved soil management practices crucial to tackle these problems by enhancing agro-ecosystem productivity, fertility, carbon sequestration. To meet Paris climate treaty pledges, must address validated approaches sequestration stabilization. The present synthesis assesses a range of current potential agricultural (AMP) that have effect on organic (SOC) storage Through two strategies—increasing inputs (e.g., enhanced primary production, fertilizers) reducing SOC losses erosion, managing respiration)—AMP can either sequester, up 714 ± 404 (compost) kg C ha−1 y−1, having no distinct impact (mineral fertilization), or even reduce stocks in topsoil (bare fallow). Overall, subsoil (>40 cm) requires further investigation.

Bacterial and Fungal Biocontrol Agents for Plant Disease Protection: Journey from Lab to Field, Current Status, Challenges, and Global Perspectives

Molecules, Год журнала: 2023, Номер 28(18), С. 6735 - 6735

Опубликована: Сен. 21, 2023

Plants are constantly exposed to various phytopathogens such as fungi, Oomycetes, nematodes, bacteria, and viruses. These pathogens can significantly reduce the productivity of important crops worldwide, with annual crop yield losses ranging from 20% 40% caused by pathogenic diseases. While use chemical pesticides has been effective at controlling multiple diseases in major crops, excessive synthetic chemicals detrimental effects on environment human health, which discourages pesticide application agriculture sector. As a result, researchers worldwide have shifted their focus towards alternative eco-friendly strategies prevent plant Biocontrol is less toxic safer method that reduces severity A variety biological control agents (BCAs) available for use, but further research needed identify potential microbes natural products broad-spectrum antagonistic activity This review aims highlight importance biocontrol managing Furthermore, role beneficial current status mechanisms will be summarized.

Disentangling the genetic basis of rhizosphere microbiome assembly in tomato

Nature Communications, Год журнала: 2022, Номер 13(1)

Опубликована: Июнь 16, 2022

Abstract Microbiomes play a pivotal role in plant growth and health, but the genetic factors involved microbiome assembly remain largely elusive. Here, we map molecular features of rhizosphere as quantitative traits diverse hybrid population wild domesticated tomato. Gene content analysis prioritized tomato trait loci suggests basis for differential recruitment various rhizobacterial lineages, including Streptomyces -associated 6.31 Mbp region harboring domestication sweeps encoding, among others, iron regulator FIT water channel aquaporin SlTIP2.3. Within metagenome-assembled genomes root-associated Cellvibrio , identify bacterial genes metabolism polysaccharides, iron, sulfur, trehalose, vitamins, whose variation associates with specific QTLs. By integrating ‘microbiomics’ genetics, pinpoint putative reciprocal underlying assembly, thereby providing first step towards plant-microbiome breeding programs.

The ISME Journal, Год журнала: 2021, Номер 15(9), С. 2708 - 2722

Опубликована: Март 26, 2021

Abstract The full potential of managing microbial communities to support plant health is yet-unrealized, in part because it remains difficult ascertain which members are most important for the plant. However, microbes that consistently associate with a species across varied field conditions and over development likely engage host or environment. Here, we applied abundance-occupancy concepts from macroecology quantify core membership bacterial/archaeal fungal rhizosphere common bean (Phaseolus vulgaris). Our study investigated microbiome persisted multiple dimensions agriculture, including major U.S. growing regions (Michigan, Nebraska, Colorado, Washington), development, annual plantings, divergent genotypes, also included re-analysis public data beans grown Colombia. We found 48 bacterial taxa were detected all samples, inclusive datasets dimensions. This suggests reliable enrichment these environment time-independence their association More generally, breadth ecologically this work (space, time, genotype, management) provides an example how systematically identify stably-associated members, can be other hosts systems.
