“…Nevertheless, the effect on the α-diversity was only observed for the fungal community, while diversity and richness of the bacteriome remained mostly unchanged. This agrees with previous studies dealing with herbaceous plants under different managements [26] , [27] , [28] , [59] , [60] . In fact, a stronger effect on fungal diversity can be related to differences in soil organic matter content [61] , in agreement with our results.…”

“…Therefore, manure amendment is known to modify soil as well as root microbiota. This has been widely studied for herbaceous plants but scarcely for woody species [23] , [24] , [25] , [26] , [27] , [28] . Although several studies on the effect of manure amendment on olive tree yield are available [5] , [29] , [30] , [31] , [32] , little is known about its influence on the olive root microbiome.…”

“…Additionally, animal manure or compost-derived organic fertilizers may carry pathogens and contaminants like antibiotic resistance genes, bringing concerns for their application ( Xu et al, 2020 ; Wei et al, 2022 ). So, as an integrated nutrient management practice, the combined application of chemical and organic fertilizers offers several benefits, such as providing a balanced nutrient supply and mitigating the environmental risks associated with the excessive use of synthetic fertilizers ( Liu et al, 2022 ; Wu et al, 2022 ). However, balancing the application rates of chemical and organic fertilizers and determining the optimal ratio and timing of application can be challenging.…”

The combined application of chemical and organic fertilizers has been recognized to enhance soil fertility and foster the soil microbial ecosystem. However, the optimal ratio of chemical and organic fertilizers in oilseed rape cultivation is still uncertain, and the role of rhizosphere effect is still unclear. Thus, this study aimed to elucidate the impacts of varying ratios of chemical and organic fertilizers on the structure and potential functionalities of rhizosphere and non-rhizosphere soil microbial communities. The interplay of microbial communities with soil properties and oilseed rape root exudates was investigated in controlled pot cultivations receiving varying ratios of chemical and organic fertilizers. Results indicated clear segregation in the soil bacterial community, influenced by both fertilization treatments and rhizosphere effects. The bacterial community structure significantly correlated with nitrate nitrogen, organic acids, and dissolved organic carbon (DOC) content. Rhizosphere effects led to increased bacteria abundance, reduced diversity, and decreased network stability. Notably, F3 treatment receiving 25% chemical and 75% organic fertilizers showed a significantly higher abundance at 1.43 × 1011 copies g−1 dry soil, accompanied by increased species and genetic diversity, and ecological network complexity. This treatment also yielded the highest aboveground biomass of oilseed rape. However, the application of organic fertilizers also increased the risk of plant pathogenicity. This study reveals the impact of fertilizers and rhizosphere effects on soil microbial community structure and function, shedding light on the establishment of more effective fertilization schemes for oilseed rape agriculture.

“…Maize's high economic value ($9.2 billion in US exports alone in 2020) [64,65] and extensive genetic variation have made it a model organism for the last century [66]. Although many studies have looked at the maize microbiome [3, 33-36, 67, 68], the majority of these studies use inbred research lines, while few looked at normal production conditions or used commercial varieties [69][70][71][72]. As microbial interactions can be effected by host genetics, current understanding and assumption about the maize microbiome using dedicated inbred lines may not translate to high performing commercial varieties.…”

The maize microbiome consists of microbes that are associated with plants, and can be shaped by the host plant, the environment, and microbial partners, some of which can impact plant performance. We used a public dataset to analyze bacteria and fungi in the soil, rhizosphere, roots, and leaves of commercial maize at 30 locations across the US. We found that both tissue type and location had significant effects on community structure and makeup, although the patterns differed in bacteria and fungi based on tissue type. We also found many differences in predicted microbial gene pathways between tissues, with location also shaping predicted functional gene profiles. We found a pattern of potential interaction between fungi and bacteria, and potential intra-kingdom mutualism, in microbiome networks. The robustness of these networks was dependent upon tissue, with endophytes in leaves and roots showing significantly higher natural connectivity. Within a tissue, this connectivity was relatively stable across locations. We identified environment and soil characteristics that may impact tissue specific microbial abundance. Sulfate level in the soil was positively correlated with Proteobacteria abundance, but negatively correlated with Firmicutes abundance in the roots and leafs. Ascomycota appears to be affected by different environmental variables in each tissue. We also identified gene functions and enzymes which may be necessary to allow microbes to transition across compartments and become endophytes.
