Arbuscular mycorrhiza fungi (AMF) forms a multi-beneficial symbiotic relationship with the host plant, therefore it is considered to be an effective helper to promote plant health. However, failure to consider the source or universality of AMF is often unstable during application. Therefore, it is necessary to screen potential AMF inoculants based on the source and the relationship with host.

Native core microbiomes represent a unique opportunity to support food provision and plant-based industries. Yet, these microbiomes are often neglected when developing synthetic communities (SynComs) to support plant health and growth. Here, we study the contribution of native core, native non-core and non-native microorganisms to support plant production.

Next-generation sequencing (NGS) has revolutionized taxa identification within contaminant-degrading communities. However, uncovering a core degrading microbiome in diverse polluted environments and understanding its associated microbial interactions remains challenging. In this study, we isolated two distinct microbial consortia, namely MA-S and Cl-G, from separate environmental samples using 1,4-dioxane as a target pollutant.

A wild melon reference genome elucidates the genomic basis of fruit acidity domestication. Structural variants (SVs) have been reported to impose major effects on agronomic traits, representing a significant contributor to crop domestication. However, the landscape of SVs between wild and cultivated melons is elusive and how SVs have contributed to melon domestication remains largely unexplored.

Article Synopsis
  • BTB and TAZ domain proteins (BTs) are crucial adaptors for the CUL3-RING ubiquitin ligase complex, which helps target proteins for ubiquitination under various conditions.
  • The study reveals that the calmodulin-like protein MdCML15 negatively regulates the function of the apple scaffold protein MdBT2, influencing processes related to membrane H-ATPase regulation and tolerance to iron deficiency.
  • The findings suggest that MdCML15, through its interactions with MdBT2 and the target protein MdbHLH104, plays a significant role in lowering rhizosphere pH and maintaining iron balance in apple plantlets.

Heterogeneous Fenton oxidation using traditional catalysts with HO for the degradation of 1,4-dioxane (1,4-DX) still presents challenge. In this study, we explored the potential of Fe-ZSM-5 zeolites (Fe-zeolite) with three Si/Al ratios (25, 100, 300) as heterogeneous Fenton catalysts for the removal of 1,4-DX from aqueous solution. FeO or ZSM-5 alone provided ineffective in degrading 1,4-DX when combined with HO.

Article Synopsis
  • The study focuses on creating effective microbial consortia to break down 1,4-dioxane, a harmful contaminant, and highlights the challenges researchers face due to microbial diversity.
  • Researchers used a combination of dilution-to-extinction and reculture methods to successfully identify key bacteria, demonstrating that Shinella species are more effective at degrading 1,4-dioxane than Xanthobacter species.
  • The findings suggest that these techniques not only simplify the assembly of microbial communities but also help in pinpointing important degraders for environmental bioremediation efforts.

Soil-borne pathogens pose a major threat to food production worldwide, particularly under global change and with growing populations. Yet, we still know very little about how the soil microbiome regulates the abundance of soil pathogens and their impact on plant health. Here we combined field surveys with experiments to investigate the relationships of soil properties and the structure and function of the soil microbiome with contrasting plant health outcomes.

Bacterial wilt caused by (Rs) is one of the most important diseases found in ginger; however, the disease resistance mechanisms dependent on root bacteria and exudates are unclear. In the present study, we analyzed the changes in the composition of rhizobacteria, endobacteria, and root exudates during the pathogenesis of bacterial wilt using high-throughput sequencing and gas chromatography-mass spectrometry (GC-MS). Rs caused bacterial wilt in ginger with an incidence of 50.

Introduction: Organic manure, plant growth-promoting microorganisms, and biocontrol agents are widely used to sustainably control soil-borne diseases. However, how and whether organic manure inoculated with biocontrol agents alters soil microbiota and reduces disease severity is poorly understood.

Methods: Here, we examined changes to the soil microbial community, soil properties, and incidence of wilt disease in response to several fertilization regimes.

Myxobacteria are unique predatory microorganisms with a distinctive social lifestyle. These taxa play key roles in the microbial food webs in different ecosystems and regulate the community structures of soil microbial communities. Compared with conditions under conventional management, myxobacteria abundance increases in the organic soil, which could be related to the presence of abundant myxobacteria in the applied compost manure during organic conditions.

Microbial treatment has recently been attracting attention as a sustainable agricultural strategy addressing the current problems caused by unreasonable agricultural practices. However, the mechanism through which microbial inoculants promote plant growth is not well understood. In this study, two phosphate-solubilizing bacteria (PSB) were screened, and their growth-promoting abilities were explored.

The occurrence of sulfonamides in the environment is a severe global threat to public health due to the increasing prevalence of antibiotic selection pressure that may lead to the development of antibiotic resistance. We report an enhanced biodegradation of sulfadimethoxine (SDM) by Phanerochaete chrysosporium (Pc) with lignocellulosic biomass (Lb) using FeO-ZSM-5 as a catalyst (Pc/FeO-ZSM-5/Lb). SDM was completely degraded within 4 days at pH 7.

This study used integrated omics technologies to investigate the potential novel pathways and enzymes for 1,4-dioxane degradation by a consortium enriched from activated sludge of a domestic wastewater treatment plant. An unclassified genus belonging to Xanthobacteraceae increased significantly after magnetic nanoparticle-mediated isolation for 1,4-dioxane degraders. Species with relatively higher abundance (> 0.

The overuse of antibiotics and subsequent enrichment of antibiotic resistant microbes in the natural and built environments is a severe threat to global public health. In this study, a Phanerochaete chrysosporium fungal-luffa fiber system was found to efficiently biodegrade two sulfonamides, sulfadimethoxine (SDM) and sulfadizine (SDZ), in cow urine wastewater. Biodegradation pathways were proposed on the basis of key metabolites identified using high performance liquid chromatography coupled with quadrupole-time-of-flight mass spectrometry (HPLC-QqTOF-MS).

The use of bioaugmented zeolite (bio-zeolite) can be an effective technology for irreversibly removing recalcitrant organic pollutants in aqueous mixtures. Removal of 1,4-dioxane by a bio-zeolite ( CB1190-bioaugmented ZSM-5) in the presence of several chlorinated volatile organic compounds (CVOCs) was superior to removal by adsorption using abiotic zeolite. Mixtures containing 1,1-dichloroethene (1,1-DCE) were an exception, which completely inhibited the bio-zeolite system.

  • Apple ring rot is a significant disease affecting apple fruit quality and yield globally, but its molecular mechanisms are not well understood.
  • Recent research identified MdPOB1, an E3 ligase protein, as a suppressor of apple's defense mechanisms against the pathogen Botryosphaeria dothidea by degrading the positive regulator MdPUB29.
  • The study also found that MdPOB1's role in regulating MdPUB29 impacts the levels of H2O2 and salicylic acid signaling, providing new insights into apple resistance to ring rot.
