Abstract The northeast region of China is an important grain‐growing area. However, severe soil salinization in the impairs plant production. In present study, organic fertilizer application (composted poultry manure) was evaluated as a potential strategy for remediating saline–alkali and promoting rice growth. Following continuous 4 years, contents basic cations, including sodium (Na + ) chlorine cations (Cl − ), decreased significantly ( p < .05) (soil Na from 24.3 mg kg −1 to 21.8 Cl ‐ 570.4 38.5 while matter (SOM), total nitrogen (TN), phosphorus (TP), available (AN) potassium (AK) were markedly increased (especially AK, which 85.8 141.7 compared treatment without application. addition, relative abundance growth‐promoting bacteria such Thiobacillius, Methylobacter, Rhodoferax, Lysobacter Flavobacterium significantly, whereas halophilic genera Nitriliruptor, Mongoliicoccus, Litoribacter, Halomonas Aliidiomarina markedly.

According structural equation modelling results, bacterial key factor driving maintenance healthy growth soil. These results suggested fertilizers could improve physicochemical properties by altering interactions between plants bacteria, example, via recruitment specific beneficial microbial communities increase their salinity–alkali stress tolerance, and, turn, promote

Abstract While soil erosion drives land degradation, the impact of on microbial communities and multiple functions remains unclear. This hinders our ability to assess true ecosystem services restore eroded environments. Here we examined effect at two sites with contrasting texture climates. Eroded plots had lower network complexity, fewer taxa, associations among relative non-eroded plots. Soil also shifted community composition, decreased abundances dominant phyla such as Proteobacteria, Bacteroidetes, Gemmatimonadetes. In contrast, led an increase in some bacterial families involved N cycling, Acetobacteraceae Beijerinckiaceae. Changes microbiota characteristics were strongly related erosion-induced changes multifunctionality. Together, these results demonstrate that has a significant negative diversity functionality.

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.

Biological systems are composed of heterogeneous populations cells that intercommunicate to form a functional living tissue. function varies greatly across cells, as each single cell has unique transcriptome, proteome, and metabolome translates differences within species kingdoms. Over the past decade, substantial advancements in our ability characterize omic profiles on level have occurred, including multiple spectroscopic mass spectrometry (MS)-based techniques. Of these technologies, spatially resolved approaches, imaging (MSI), shown most progress for proteomics metabolomics.

Plants exist in close association with uncountable numbers of microorganisms around, on, and within them. Some these endophytically colonize plant roots. The colonization roots by certain symbiotic strains plant-associated bacteria fungi results plants performing better than whose are colonized only the wild populations microbes. We consider here crop inhabited introduced organisms, referring to them as Enhanced Plant Holobionts (EPHs). EPHs frequently exhibit resistance specific diseases pests (biotic stresses); abiotic stresses such drought, cold, salinity, flooding; enhanced nutrient acquisition use efficiency; increased photosynthetic capability; ability maintain efficient internal cellular functioning. microbes described generate effects part through their production Symbiont-Associated Molecular Patterns (SAMPs) that interact receptors cell membranes. Such interaction transduction systemic signals cause plant-wide changes plants’ gene expression physiology. EPH arise not from plant-microbe interactions, but also microbe-microbe interactions like competition, mycoparasitism, antibiotic production. When root shoot growth a consequence endophytes, this increases yield plants. An additional benefit growing larger systems having greater capability is sequestration atmospheric CO 2 . This transferred where sequestered C, exudation or decomposition, becomes total soil carbon, which reduces global warming potential atmosphere.

Plants grown in natural soil are colonized by phylogenetically structured communities of microbes known as the microbiota. Individual can activate microbe-associated molecular pattern (MAMP)-triggered immunity (MTI), which limits pathogen proliferation but curtails plant growth, a phenomenon growth-defence trade-off. Here, we report that, monoassociations, 41% (62 out 151) taxonomically diverse root bacterial commensals suppress Arabidopsis thaliana growth inhibition (RGI) triggered immune-stimulating MAMPs or damage-associated patterns. Amplicon sequencing 16S rRNA genes reveals that immune activation alters profile synthetic (SynComs) comprising RGI-non-suppressive strains, whereas presence RGI-suppressive strains attenuates this effect. Root colonization SynComs with different complexities and activities expression 174 core host genes, functions related to development nutrient transport. Furthermore, specifically downregulate subset immune-related genes. Precolonization plants SynComs, mutation one commensal-downregulated transcription factor, MYB15, renders more susceptible opportunistic Pseudomonas pathogens. Our results suggest modulate susceptibility pathogens either eliciting dampening MTI responses, respectively. This interplay buffers system against perturbation defence-associated inhibition, ultimately leading commensal-host homeostasis.
