Abstract Background Plants live with diverse microbial communities which profoundly affect multiple facets of host performance, but if and how development impacts the assembly, functions interactions crop microbiomes are poorly understood. Here we examined both bacterial fungal across soils, epiphytic endophytic niches leaf root, plastic fake plant (representing environment-originating microbes) at three developmental stages maize two contrasting sites, further explored potential function phylloplane based on metagenomics. Results Our results suggested that stage had a much stronger influence diversity, composition interkingdom networks in compartments than strongest effect phylloplane. Phylloplane were co-shaped by growth seasonal environmental factors, air (represented plants) as its important source. Further, found more strongly driven deterministic processes early similar pattern was for late stage. Moreover, taxa played role network yield prediction stage, while did so Metagenomic analyses indicated possessed higher functional diversity genes related to nutrient provision enriched N assimilation C degradation Coincidently, abundant beneficial like Actinobacteria, Burkholderiaceae Rhizobiaceae observed saprophytic fungi Conclusions suggest influences microbiome assembly functions, take differentiated ecological different development.

Major losses of crop yield and quality caused by soil-borne plant diseases have long threatened the ecology economy agriculture forestry. Biological control using beneficial microorganisms has become more popular for management pathogens as an environmentally friendly method protecting plants. Two major barriers limiting disease-suppressive function biocontrol microbes are inadequate colonization hosts inefficient inhibition pathogen growth, due to biotic abiotic factors acting in complex rhizosphere environments. Use a consortium microbial strains with disease inhibitory activity may improve efficacy disease-inhibiting microbes. The mechanisms biological not fully understood. In this review, we focus on bacterial fungal agents summarize current state use single strain multi-strain consortia diseases. We discuss potential used components suppressing efficacy. emphasize interaction-related be considered when constructing multiple-strain propose workflow assembling them applying reductionist synthetic community approach.

Return of the Lemnaceae: duckweed as a model plant system in the genomics and postgenomics era

The Plant Cell, Journal Year: 2021, Volume and Issue: 33(10), P. 3207 - 3234

Published: July 16, 2021

The aquatic Lemnaceae family, commonly called duckweed, comprises some of the smallest and fastest growing angiosperms known on Earth. Their tiny size, rapid growth by clonal propagation, facile uptake labeled compounds from media were attractive features that made them a well-known model for plant biology 1950 to 1990. Interest in duckweed has steadily regained momentum over past decade, driven part need identify alternative plants traditional agricultural crops can help tackle urgent societal challenges, such as climate change population expansion.

Intimate Association of PRR- and NLR-Mediated Signaling in Plant Immunity

Molecular Plant-Microbe Interactions, Journal Year: 2020, Volume and Issue: 34(1), P. 3 - 14

Published: Oct. 13, 2020

This article is part of the Top 10 Unanswered Questions in MPMI invited review series. Plants recognize presence or invasion microbes through cell surface-localized pattern recognition receptors (PRRs) and intracellular nucleotide-binding domain leucine-rich repeat (NLRs). Although PRRs NLRs are activated by ligands located different subcellular compartments distinct mechanisms, signals initiated from converge into several common signaling pathways with dynamics. Increasing evidence suggests that PRR- NLR-mediated extensively crosstalk such interaction can greatly influence immune response outcomes. Sophisticated experimental setups enabled dissection events downstream fine temporal spatial resolution; however, molecular links underlying observed interactions PRR NLR remain to be elucidated. In this review, we summarize latest knowledge about activation mediated NLRs, deconvolute intimate association between signaling, propose hypotheses guide further research on key topics.

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.
