“…Research on the role of P limitations in shaping soil bacterial communities has revealed that Firmicutes , including Planococcaceae and Bacillaceae , are enriched in high P soils, and Planococcaceae is relatively more abundant than Bacillaceae ( Oliverio et al, 2020 ). Notably, the abundance of Planococcaceae and Bacillacea related to functions of carbon degradation and P cycling increase sugarcane yield ( Silva et al, 2021 ). Rhodobacteraceae is a family in Alphaproteobacteria that is involved in C, N and S cycling processes in the marine environment ( Zheng et al, 2015 ; Zhang et al, 2019 ).…”

Malic acid is a component of the rhizosphere exudate and is vital for crop growth. However, little information is available about the effects of external applications of malic acid on the nutrient absorption and quality of grape fruit, and few studies have been performed on the relationship between the changes in the rhizosphere microbial community and nutrient absorption and fruit quality of grapes after adding malic acid. Here, the LM (low concentration of malic acid) and HM (high concentration of malic acid) treatments comprised 5% and 10% malic acid (the ratio of acid to the total weight of the fertilizer) combined with NPK fertilizer, respectively. Applying malic acid changed the grape rhizosphere microbial community structure and community-level physiological profile (CLPP) significantly, and HM had a positive effect on the utilization of substrates. The microbial community structure in the rhizosphere of the grapes with added malic acid was closely related to the CLPP. The N and P content in the leaves and fruits increased after applying malic acid compared to the control, while K content in the fruits increased significantly. In addition, malic acid significantly reduced the weight per fruit, significantly increased soluble sugar content (SSC) and vitamin C content of the fruit, and significantly improved the fruit sugar-acid ratio and grape tasting score. Moreover, the principal component analysis and grape nutrient and fruit quality scores showed that grape nutrients and fruit quality were significantly affected by malic acid and ranked as 5% malic acid > 10% malic acid > control. Pearson’s correlation heatmap of microbial composition, nutrient absorption and fruit quality of the grapes showed that the grape microbial community was closely related to grape nutrients and fruit quality. Adding malic acid was positively correlated to Planococcaceae, Bacillaceae, Woeseiaceae and Rhodobacteraceae. Furthermore, Planococcaceae, Bacillaceae, Woeseiaceae and Rhodobacteraceae were closely related to grape nutrient absorption and fruit quality. Bacillaceae and Woeseiaceae were positively correlated with total soluble sugar, while Planococcaceae and Rhodobacteraceae were positively correlated with titratable acid. Hence, Bacillaceae and Woeseiaceae were the key bacteria that played a major role in grape fruit quality and nutrient absorption after applying malic acid water-soluble fertilizer.

“…The second-ranked dominant genus, with a relative abundance of an order of magnitude higher than that in the undisturbed soil, namely Chaetomium of Chaetomiaceae / Sordariales / Sordariomycetes / Ascomycota , is a saprotrophic fungus, normally found in soil and organic composts [ 28 ] as it degrades cellulose and other organic materials by producing lytic enzymes [ 29 ]. As the genus representatives were shown to be the main hemicellulose degraders at the cooling stage of crop residue composting [ 30 ], its increased presence, like Mortierella ’s, in the wheat-cropped fields at the end of autumn long after the harvest was most likely determined by the presence dead phytomass in soil.…”

“…Podospora fungi are widely spread in the environment and possess a diverse enzymic repertoire, including ligninolytic activity [ 42 ]. Chaetomium is described above as a cellulose and organic matter degrader [ 27 , 28 ]. Lecythophora , widely distributed in soil, wood, vegetative matter, and polluted water saprotrophic lignocellulose-inhabiting sordariomycete ( Coniochaetaceae / Coniochaetales / Sordariomycetes/Ascomycota ) and known as an active participant at the early phase of straw residue decomposition [ 34 ], in our study was apparently involved in the same process in the cropped fields.…”

Managing soil biodiversity by reduced or no tillage is an increasingly popular approach. Soil mycobiome in Siberian agroecosystems has been scarcely studied; little is known about its changes due to tillage. We studied mycobiome in Chernozem under natural steppe vegetation and cropped for wheat by conventional or no tillage in a long-term field trial in West Siberia, Russia, by using ITS2 rDNA gene marker (Illumina MiSeq sequencing). Half of the identified OTUs were Ascomycota with 82% of the total number of sequence reads and showing, like other phyla (Basidiomycota, Zygomycota, Mortierellomycota, Chytridiomycota, Glomeromycota), field-related differential abundance. Several dominant genera (Mortierella, Chaetomium, Clonostachys, Gibberella, Fusarium, and Hypocrea) had increased abundance in both cropped soils as compared with the undisturbed one and therefore can be safely assumed to be associated with wheat residues. Fungal OTUs’ richness in cropped soils was less than in the undisturbed one; however, no tillage shifted soil mycobiome composition closer to the latter, albeit, it was still similar to the ploughed soil, despite different organic matter and wheat residue content. The study provided the first inventory of soil mycobiome under different tillage treatments in the south of West Siberia, where wheat production is an important section of the regional economy.

“…As another one indispensable component in rhizosphere microbiota, fungi also play critical roles in promoting rhizospheric nutrient cycle for better soil quality (Liu et al 2019). Different from bacteria, fungi have a stronger ability to degrade recalcitrant litter (Silva et al 2021). For example, the dominant fungi Ascomycota (including class Sordariomycetes and Dothideomycetes) are mainly responsible for lignocellulose decomposition and involved in nutrient cycling (Zhou et al 2016;Zheng et al 2021).…”

Biogas slurry (BS) is widely used as a liquid fertilizer in paddy fields. A growing body of evidence shows that rhizosphere microbiota is important for plant growth and reproduction. However, the dynamic responses of rhizosphere microbiomes of field-grown rice to BS application still remain unknown. In this study, a field experiment was conducted to further understand the impacts of BS fertilizer (BCF) on the dynamic changes of rhizosphere microbiota throughout the life cycle of rice with conventional chemical fertilizer (CF) treatment as control. The results demonstrated that BS could increase the N-, P- and C- level in paddy water as well as rhizospheric microbial abundance and diversity of paddy fields compared with control. In particular, the phosphate-solubilizing- and cellulose-decomposition-related bacteria (e.g. Bacillus) and fungi (e.g. Mortierella) were more abundant in the rhizosphere of BCF than those of CF. Moreover, these above-mentioned microbes increased markedly at the reproductive stages compared with those at vegetative stages in BCF, which could promote rice to obtain available nutrient (phosphorus and carbon) at low fertility input stages (the reproductive stages). It was noted that denitrifying-related bacteria (e.g. Steroidobacteraceae) decreased and dissimilatory nitrate reduction to ammonia (DNRA) -related bacteria increased generally at the reproductive stages, which could reduce N-loss and help to N-fixation. Furthermore, correlation network showed that nutrient-cycles-related microbes were more closely interconnected in BCF than control. These observations demonstrated the application of BS could regulate root-related microbiomes towards a beneficial fertilizer use for rice production.
