A multifactorial stress combination occurs when more than two to three abiotic and/or biotic factors simultaneously impact a plant.Global warming, climate change, and industrial pollution could result in an increase the frequency, complexity, intensity of combinations impacting plants, soils, microbial communities.With number survival growth plants declines, even if levels each these individual stresses is very low.The response unique involves many transcripts genes that are not altered different applied individually.The harmful effects on soil properties, diversity communities should serve as dire warning our society prompt us act drastically reduce sources environment. Global environmental present with stresses. Although much known about how acclimate stresses, little they respond occurring together, namely combination.

Rhizosphere bacteriome structure and functions

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: Feb. 11, 2022

Abstract Microbial composition and functions in the rhizosphere—an important microbial hotspot—are among most fascinating yet elusive topics ecology. We used 557 pairs of published 16S rDNA amplicon sequences from bulk soils rhizosphere different ecosystems around world to generalize bacterial characteristics with respect community diversity, composition, functions. The selects microorganisms soil function as a seed bank, reducing diversity. is enriched Bacteroidetes, Proteobacteria, other copiotrophs. Highly modular but unstable networks (common for r -strategists) reflect interactions adaptations dynamic conditions. Dormancy strategies are dominated by toxin–antitoxin systems, while sporulation common soils. Functional predictions showed that genes involved organic compound conversion, nitrogen fixation, denitrification were strongly (11–182%), nitrification depleted.

Linking Plant Secondary Metabolites and Plant Microbiomes: A Review

Frontiers in Plant Science, Journal Year: 2021, Volume and Issue: 12

Published: March 2, 2021

Plant secondary metabolites (PSMs) play many roles including defense against pathogens, pests, and herbivores; response to environmental stresses, mediating organismal interactions. Similarly, plant microbiomes participate in of the above-mentioned processes directly or indirectly by regulating metabolism. Studies have shown that plants can influence their microbiome secreting various and, turn, may also impact metabolome host plant. However, not much is known about communications between interacting partners phenotypic changes. In this article, we review patterns potential underlying mechanisms interactions PSMs microbiomes. We describe recent developments analytical approaches methods field. The applications these new increased our understanding relationships Though current studies primarily focused on model organisms, results obtained so far should help future agriculturally important facilitate development manipulate PSMs–microbiome with predictive outcomes for sustainable crop productions.

Published: Dec. 20, 2021

Modern intensive agricultural practices face numerous challenges that pose major threats to global food security. In order address the nutritional requirements of ever-increasing world population, chemical fertilizers and pesticides are applied on large scale increase crop production. However, injudicious use agrochemicals has resulted in environmental pollution leading public health hazards. Moreover, agriculture soils continuously losing their quality physical properties as well (imbalance nutrients) biological health. Plant-associated microbes with plant growth- promoting traits have enormous potential solve these play a crucial role enhancing biomass yield. The beneficial mechanisms growth improvement include enhanced nutrient availability, phytohormone modulation, biocontrol phytopathogens amelioration biotic abiotic stresses. Solid-based or liquid bioinoculant formulation comprises inoculum preparation, addition cell protectants such glycerol, lactose, starch, good carrier material, proper packaging best delivery methods. Recent developments entrapment/microencapsulation, nano-immobilization microbial bioinoculants biofilm-based biofertilizers. This review critically examines current state-of-art strains biofertilizers important roles performed by maintaining soil fertility productivity.

Disease-induced changes in plant microbiome assembly and functional adaptation

Microbiome, Journal Year: 2021, Volume and Issue: 9(1)

Published: Sept. 15, 2021

The plant microbiome is an integral part of the host and increasingly recognized as playing fundamental roles in growth health. Increasing evidence indicates that rhizosphere recruits beneficial microbes to suppress soil-borne pathogens. However, ecological processes govern assembly functions below- aboveground compartments under pathogen invasion are not fully understood. Here, we studied bacterial fungal communities associated with 12 (e.g., soils, roots, stems, fruits) chili pepper (Capsicum annuum L.) using amplicons (16S ITS) metagenomics approaches at main production sites China investigated how Fusarium wilt disease (FWD) affects assembly, co-occurrence patterns, plant-associated microbiomes.The amplicon data analyses revealed FWD affected less on reproductive organs (fruit) than vegetative (root stem), strongest impact upper stem epidermis. Fungal intra-kingdom networks were stable their more sensitive communities. analysis microbial interkingdom network further indicated destabilized induced importance taxa. Although diseased plants susceptible colonization by other pathogenic fungi, can also recruit potential bacteria. Some taxa enriched identified core for microbiomes hub networks. On hand, metagenomic significant enrichment several functional genes involved detoxification, biofilm formation, plant-microbiome signaling pathways (i.e., chemotaxis) plants.Together, demonstrate a could bacteria mitigate changes organ facilitate or its offspring survival. may attract through modulation pathways. These findings significantly advance our understanding interactions provide important harnessing sustainable agriculture. Video abstract.
