Despite the numerous benefits plants receive from probiotics, maintaining consistent results across applications is still a challenge. Cultivation-independent methods associated with reduced sequencing costs have considerably improved overall understanding of microbial ecology in plant environment. As result, now, it possible to engineer consortium microbes aiming for health. Such synthetic communities (SynComs) contain carefully chosen species produce desired microbiome function. Microbial biofilm formation, production secondary metabolites, and ability induce resistance are some traits consider when designing SynComs. Plant-associated not assembled randomly. Ecological theories suggest that these defined phylogenetic organization structured by general community assembly rules. Using machine learning, we can study rules target functions generate phenotypes. Well-structured assemblages more likely lead stable SynCom thrives under environmental stressors as compared classical selection single activities or taxonomy. However, ensuring colonization long-term phenotype stability one challenges overcome SynComs, may change over time horizontal gene transfer retained mutations. Here, explored advances made research regarding health, focusing on bacteria, they most dominant form other members commonly found studies.

The root microbiome refers to the community of microbes living in association with a plant's roots, and includes mutualists, pathogens, commensals. Here we focus on recent advances study commensal which is major research object microbiome-related researches. With rapid development new technologies, plant-commensal interactions can be explored unprecedented breadth depth. Both soil environment host plant drive assembly. bulk seed bank potential commensals, plants use exudates immune responses build healthy microbial communities from available microbes. extends functional system by participating variety processes, including nutrient absorption, growth promotion, resistance biotic abiotic stresses.

Abstract The role of rhizosphere microbiota in the resistance tomato plant against soil-borne Fusarium wilt disease (FWD) remains unclear. Here, we showed that FWD incidence was significantly negatively correlated with diversity both bacterial and fungal communities. Using microbiological culturomic approach, selected 205 unique strains to construct different synthetic communities (SynComs), which were inoculated into germ-free seedlings, their roles suppressing monitored using omics approach. Cross-kingdom (fungi bacteria) SynComs most effective than those Fungal or Bacterial alone. This effect underpinned by a combination molecular mechanisms related immunity microbial interactions contributed study provides new insight dynamics pathogen suppression host interactions. Also, formulation manipulation for functional complementation constitute beneficial strategy controlling disease.

Published: June 14, 2022

Abstract The phytohormones salicylic acid (SA) and jasmonic (JA) are major players in plant immunity. Numerous studies have provided evidence that SA- JA-mediated signaling interact with each other (SA-JA crosstalk) to orchestrate immune responses against pathogens. At the same time, SA-JA crosstalk is often exploited by pathogens promote their virulence. In this review, we summarize our current knowledge of molecular mechanisms for modulations during pathogen infection.

Abstract Genetic and environmental factors collectively determine plant growth yield. In the past 20 years, genome-wide association studies (GWAS) have been conducted on crops to decipher genetic loci that contribute yield, however, genotype appears be insufficient explain trait variations. Here, we unravel associations between genotypic, phenotypic, rhizoplane microbiota variables of 827 foxtail millet cultivars by an integrated GWAS, microbiome-wide (MWAS) microbiome (mGWAS) method. We identify 257 microbial biomarkers associated with six key agronomic traits validated microbial-mediated effects using marker strains isolated from field. The composition is mainly driven variations in genes related immunity, metabolites, hormone signaling nutrient uptake. Among these, host immune gene FLS2 transcription factor bHLH35 are widely taxa rhizoplane. further uncover a genotype-microbiota interaction network contributes phenotype plasticity. dependent genotype, suggesting precision management could used engineer high-yielding agriculture systems.
