The Age of Coumarins in Plant–Microbe Interactions

Plant and Cell Physiology, Journal Year: 2019, Volume and Issue: 60(7), P. 1405 - 1419

Published: April 23, 2019

Coumarins are a family of plant-derived secondary metabolites that produced via the phenylpropanoid pathway. In past decade, coumarins have emerged as iron-mobilizing compounds secreted by plant roots and aid in iron uptake from iron-deprived soils. Members coumarin found many species. Besides their role uptake, been extensively studied for potential to fight infections both plants animals. Coumarin activities range antimicrobial antiviral anticoagulant anticancer. recent years, studies model species tobacco Arabidopsis significantly increased our understanding biosynthesis, accumulation, secretion, chemical modification modes action against pathogens. Here, we review current knowledge on different We focus simple provide an overview biosynthesis environmental stress responses, with special attention recently discovered semiochemical aboveground belowground plant-microbe interactions assembly root microbiome.

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.

Bio-organic fertilizers stimulate indigenous soil Pseudomonas populations to enhance plant disease suppression

Microbiome, Journal Year: 2020, Volume and Issue: 8(1)

Published: Sept. 22, 2020

Abstract Background Plant diseases caused by fungal pathogen result in a substantial economic impact on the global food and fruit industry. Application of organic fertilizers supplemented with biocontrol microorganisms ( i.e. bioorganic fertilizers) has been shown to improve resistance against plant pathogens at least part due impacts structure function resident soil microbiome. However, it remains unclear whether such improvements are driven specific action microbial inoculants, populations naturally fertilizer or physical-chemical properties compost substrate. The aim this study was seek ecological mechanisms involved disease suppressive activity bio-organic fertilizers. Results To disentangle mechanism action, we conducted an experiment tracking Fusarium wilt banana changes communities over three growth seasons response following four treatments: (containing Bacillus amyloliquefaciens W19), fertilizer, sterilized B . W19. We found that which re-inoculated provided similar degree suppression as non-sterilized across cropping seasons. further observed these treatments is linked communities, specifically leading increases Pseudomonas spp.. Observed correlations between amendment indigenous spp. might underlie were studied laboratory pot experiments. These studies revealed bacterial taxa synergistically increase biofilm formation likely acted plant-beneficial consortium pathogen. Conclusion Together demonstrate product inoculum within its This knowledge should help design more efficient biofertilizers designed promote function.

Metabolic regulation of the maize rhizobiome by benzoxazinoids

The ISME Journal, Journal Year: 2019, Volume and Issue: 13(7), P. 1647 - 1658

Published: Feb. 22, 2019

Abstract The rhizobiome is an important regulator of plant growth and health. Plants shape their communities through production release primary secondary root metabolites. Benzoxazinoids (BXs) are common tryptophan-derived metabolites in grasses that regulate belowground aboveground biotic interactions. In addition to biocidal activity, BXs can plant–biotic interactions as semiochemicals or within-plant defence signals. However, the full extent mechanisms by which root-associated microbiome has remained largely unexplored. Here, we have taken a global approach examine regulatory activity on maize metabolome associated bacterial fungal communities. Using untargeted mass spectrometry analysis combination with prokaryotic amplicon sequencing, compared impacts three genetic mutations different steps BX pathway. We show metabolism concurrently influence type-dependent manner. Correlation between BX-controlled taxa suggested dominant role for BX-dependent metabolites, particularly flavonoids, constraining range soil microbial taxa, while stimulating methylophilic bacteria. Our study supports multilateral model control root–microbe via function metabolism.

Plants have evolved intimate interactions with soil microbes for a range of beneficial functions including nutrient acquisition, pathogen resistance and stress tolerance. Further understanding this system is promising way to advance sustainable agriculture by exploiting the versatile benefits offered plant microbiome. The rhizosphere interface between soil, as first step defense root microbiome recruitment. It features specialized microbial community, intensive microbe-plant microbe-microbe interactions, complex signal communication. To decipher assembly soybean (Glycine max), we comprehensively characterized community using 16S rRNA gene sequencing evaluated structuring influence from both host genotype source.Comparison bulk revealed significantly different composition, metabolic capacity. Soil type cooperatively modulated predominantly shaping while slightly tuned recruitment process. undomesticated progenitor species, Glycine soja, had higher diversity in types tested comparison domesticated genotypes. Rhizobium, Novosphingobium, Phenylobacterium, Streptomyces, Nocardioides, etc. were robustly enriched irrespective tested.
