“…This is because fungicides and their degradation products may be toxic against specific components of the resident microbiome [49]. The fungal Shannon diversity index indicated that seed-coating agents had significantly promotional effects on fungal diversity, while they did not affect the bacterial alpha diversity indices, which is similar to the findings of Du et al 2022 [50]. The results of PCoA showed that the seed-coating agents significantly changed the rhizosphere microbial community structure, possibly due to the influence of soil on the rhizosphere microbial communities.…”

TFC (10% thifluzamide–fludioxonil–clothianidin) is a novel wheat seed-coating agent. In the field, we confirmed that 10% TFC plays a positive role in preventing soil-borne diseases and promoting wheat seedling growth. However, its effects on rhizosphere microecology and the underlying molecular mechanism are not fully understood. Field trials revealed a positive effect on the biomass, plant height, and root length of wheat sharp eyespots in a Yingshang field, with 95.3% control efficiency. The effects of 10% TFC on the rhizosphere soil microbiome of young wheat plants were evaluated using high throughput sequencing technology. The results demonstrated that seed-coating agents significantly changed bacterial and fungal communities, and reduced the number of bacteria but increased the number of fungi. Sequence analysis revealed that the abundance of Proteobacteria, Actinobacteria, and Patescibacteria in bacteria and Ascomycota, Mortierellomycota, and Basidiomycota in fungi were significantly enriched, which have been reported as being beneficial for plant growth and pathogen resistance. In contrast, the abundance of Mucoromycota in fungi was reduced, and most of the related genera identified were pathogenic to plants. In this study, 15-day-old wheat plant tissues treated with 10% TFC were subjected to global transcriptome analysis by RNA sequencing to provide insights into the effects of 10% TFC on seedling growth. The comparative analysis of Triticum aestivum L. libraries identified 8286 differentially expressed genes (DEGs), of which 2290 and 5996 genes were up- and downregulated in seedling growth in the presence of 10% TFC, respectively. Gene ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) functional analyses were performed for up- and downregulated DEGs separately, showing that these DEGs were enriched for terms related to the phenylpropanoid biosynthesis pathway, the protein products of which promote cell differentiation and seedling growth. This research provides comprehensive insights into its effects on wheat seedling growth and the rhizosphere microecology of seed coatings and provides important insights into their regulation and into understanding the potential benefits of seed coatings in disease management and plant growth promotion.

“…For the root endosphere samples, the relative abundances of Streptomyces and Flavobacterium in the Akihime samples were significantly higher than those in the F. nilgerrensis samples ( p < 0.05), and those of Micromonospora and Pseudomonas were significantly lower than those in the F. nilgerrensis samples ( p < 0.05) ( Figure 4F ). Acidibacter, Arthrobacter, Bradyrhizobium, Gemmatimonas, Nocardioides, Var iovorax, Blastococcus, Flavisolibacter, Anaeromyxobacter, and Enterobacter ( Kuypers et al, 2018 ; Zhang et al, 2019 ; Finkel et al, 2020 ; Kalam et al, 2020 ; Du et al, 2022 ; Zhang et al, 2022a ; Li et al, 2022b ) are important sources of beneficial bacteria and were annotated in both strawberry species with significant differences in relative abundance ( p < 0.05) ( Figure 4 ). Chaetomium is a potential source of biocontrol fungi ( Moya et al, 2020 ).…”

“…The use of a large number of chemical pesticides, insecticides, fungicides, bactericides, and soil fumigants has a negative impact on soil, water resources, air, and human health ( Deng et al, 2019 ). It is reported that Blastococcus , Solirubrobacter , Gemmatimonas , among others, have the ability to degrade pesticides ( Du et al, 2022 ), while Nocardioides can withstand various low-nutrient conditions and concurrently degrade pollutants ( Ma et al, 2023 ). We observed that the relative abundances of Blastococcus, Nocardioides, Solirubrobacter , and Gemmatimonas in the rhizosphere soil samples of Akihime were significantly higher than those of F. nilgerrensis ( p < 0.05).…”

Fragaria nilgerrensis is a wild strawberry species widely distributed in southwest China and has strong ecological adaptability. Akihime (F. × ananassa Duch. cv. Akihime) is one of the main cultivated strawberry varieties in China and is prone to infection with a variety of diseases. In this study, high-throughput sequencing was used to analyze and compare the soil and root microbiomes of F. nilgerrensis and Akihime. Results indicate that the wild species F. nilgerrensis showed higher microbial diversity in nonrhizosphere soil and rhizosphere soil and possessed a more complex microbial network structure compared with the cultivated variety Akihime. Genera such as Bradyrhizobium and Anaeromyxobacter, which are associated with nitrogen fixation and ammonification, and Conexibacter, which is associated with ecological toxicity resistance, exhibited higher relative abundances in the rhizosphere and nonrhizosphere soil samples of F. nilgerrensis compared with those of Akihime. Meanwhile, the ammonia-oxidizing archaea Candidatus Nitrososphaera and Candidatus Nitrocosmicus showed the opposite tendencies. We also found that the relative abundances of potential pathogenic genera and biocontrol bacteria in the Akihime samples were higher than those in the F. nilgerrensis samples. The relative abundances of Blastococcus, Nocardioides, Solirubrobacter, and Gemmatimonas, which are related to pesticide degradation, and genus Variovorax, which is associated with root growth regulation, were also significantly higher in the Akihime samples than in the F. nilgerrensis samples. Moreover, the root endophytic microbiomes of both strawberry species, especially the wild F. nilgerrensis, were mainly composed of potential biocontrol and beneficial bacteria, making them important sources for the isolation of these bacteria. This study is the first to compare the differences in nonrhizosphere and rhizosphere soils and root endogenous microorganisms between wild and cultivated strawberries. The findings have great value for the research of microbiomes, disease control, and germplasm innovation of strawberry.

Because of its acidity, biomass pyrolytic uid (BPF) had been paid attention in the amelioration of saline soil. However, BPF contained biotoxic phenolic compounds and must be re ned before use. Most of the existing re ning methods were cumbersome and uneconomical. A simple one-step salting-out extraction system of was developed. BPF was successfully divided into upper and lower phases, and most phenolic substances were concentrated in the upper phase. The lower phase diluted 400 times at the pyrolysis temperature of 500℃ was added into saline-alkali soil, which greatly increased the content of soil available nutrients. Under the action of organic acids, soil pH and total salt content could be reduced effectively, and soil enzyme activities can be increased. Microbial community analysis showed that the addition of LP could increase the proportion of Actinomycetes, which played a bene cial role in improving soil fertility, and then improved the growth of Chinese cabbage.
