“…Recent studies have revealed that different species of plants, or even different plant traits of the same species, assemble different rhizosphere microbial communities in the same soil environment (Arafat et al, 2017;Sayer et al, 2017;Bickford et al, 2020). These complex plant-associated microbial communities are crucial for plants because they can affect plant growth, productivity, nutrients and immunity directly or indirectly (Van Wees et al, 2004;Egamberdieva et al, 2010;Erturk et al, 2010;Berendsen et al, 2012;Patel, 2018;Tahir et al, 2019;Gu et al, 2020;Song Q. et al, 2021), as well as affect host phenotypes and adaptability (Herrera Paredes et al, 2018). For instance, Finkel et al (2020) found that rhizosphere microorganisms can promote root growth by affecting plant hormone levels in Arabidopsis.…”

BackgroundPinus yunnanensis is a major silvicultural species in Southwest China. Currently, large areas of twisted-trunk Pinus yunnanensis stands severely restrict its productivity. Different categories of rhizosphere microbes evolve alongside plants and environments and play an important role in the growth and ecological fitness of their host plant. However, the diversity and structure of the rhizosphere microbial communities between P. yunnanensis with two different trunk types—straight and twisted—remain unclear.MethodsWe collected the rhizosphere soil of 5 trees with the straight and 5 trees with the twisted trunk type in each of three sites in Yunnan province. We assessed and compared the diversity and structure of the rhizosphere microbial communities between P. yunnanensis with two different trunk types by Illumina sequencing of 16S rRNA genes and internal transcribed spacer (ITS) regions.ResultsThe available phosphorus in soil differed significantly between P. yunnanensis with straight and twisted trunks. Available potassium had a significant effect on fungi. Chloroflexi dominated the rhizosphere soils of the straight trunk type, while Proteobacteria was predominant in the rhizosphere soils of the twisted trunk type. Trunk types significantly explained 6.79% of the variance in bacterial communities.ConclusionThis study revealed the composition and diversity of bacterial and fungal groups in the rhizosphere soil of P. yunnanensis with straight and twisted trunk types, providing proper microbial information for different plant phenotypes.

“…Both ash RDFs contained high amounts of Al and PLA also contained mentionable amounts of total carbon, both of which could affect Acidobacteria abundance positively. Significantly positive correlations have been reported for relative abundance of Patescibacteria with plant available P (Li et al ., 2021, Song et al ., 2021). This phylum was significantly higher for two struvite as well as one ash RDF in the current study, and these treatments also exhibited high biomass yield and in terms of the CGS60 treatment, a high Pav was also confirmed.…”

Phosphorus is a finite, essential macronutrient for agriculture. Various nutrient recycling technologies in waste streams management are currently under development in many European countries in order to alleviate the dependency of the EU on imports of non-renewable raw material for the production of mineral phosphorus fertilizers commonly used in agriculture. The resulting products such as struvites and ashes need to be assessed for their application as so-called recycling-derived fertilisers (RDF) in the agricultural sector prior to commercialisation. Albeit high phosphorus abundance in most soils, the phosphorus availability for plant growth promotion in the soil solution is usually low due to strong P sorption in soil and depends vastly on the microbial mobilisation capability of the soil. To investigate the impact of different phosphorus fertilizers on plant growth and the soil P cycling microbiota, a short-term pot trial was conducted over the period of 54 days. Lolium perenne (var. AberGreen) was grown with application of superphosphate (SP) as inorganic fertiliser, two ashes (poultry litter ash (PLA) and sewage sludge ash (SSA) and two struvites (municipal wastewater struvite (MWS) and commercial CrystalGreen (CGS) in rates of 20 and 60 kg P ha-1 in four replicates. A P-free control (SP0) was also included in the trial. Post-harvest, a positive correlation between dry weight yield and struvite application was detected, struvite P also was higher readily available and ACP activity was significantly improved for struvites at the high P application rate. The ash RDFs showed a liming effect at 60 kg P ha-1, and PLA60 negatively affected ACP activity, while PLA20 had significantly lower phoD copy numbers. P mobilization from phosphonates and phytates was not affected, TCP solubilization was negatively affected by mineral SP fertilizer application at both P concentrations. Overall, the bacterial and phoD harbouring community were not strongly affected by the P fertilization in this study.

“…Fresh cultures of the strains were spot inoculated on inorganic phosphorus bacterial screening medium (NBRIP, glucose 10 g, MgCl 2 5 g, NaCl 0.3 g, MgSO 4 ·7H 2 O 0.3 g, MnSO 4 0.03 g, K 2 SO 4 0.3 g, FeSO 4 0.03 g, (NH 4 ) 2 SO 4 0.5 g, Ca 3 (PO 4 ) 2 5 g, agar 15 g, distilled water 1,000 mL), and incubated at 30°C for 3 d to observe the growth of colonies and the formation of hyaline circles. The solubility of the strains for inorganic phosphorus was determined using the molybdenum blue colorimetric method ( Song et al, 2021 ).…”

The HSE-12 strain isolated from peanut rhizosphere soil was identified as Bacillus amyloliquefaciens by observation of phenotypic characteristics, physiological and biochemical tests, 16S rDNA and gyrB gene sequencing. In vitro experiments showed that the strain possessed biocontrol activity against a variety of pathogens including Sclerotium rolfsii. The strain has the ability to produce hydrolytic enzymes, as well as volatile organic compounds with antagonistic and probiotic effects such as ethyleneglycol and 2,3-butanediol. In addition, HSE-12 showed potassium solubilizing (10.54 ± 0.19 mg/L), phosphorus solubilization (168.34 ± 8.06 mg/L) and nitrogen fixation (17.35 ± 2.34 mg/g) abilities, and was able to secrete siderophores [(Ar-A)/Ar × 100%: 56%] which promoted plant growth. After inoculating peanut with HSE-12, the available phosphorus content in rhizosphere soil increased by 27%, urease activity increased by 43%, catalase activity increased by 70% and sucrase activity increased by 50% (p < 0.05). The dry weight, fresh weight and the height of the first pair of lateral branches of peanuts increased by 24.7, 41.9, and 36.4%, respectively, compared with uninoculated peanuts. In addition, compared with the blank control, it increased the diversity and richness of peanut rhizosphere bacteria and changed the community structure of bacteria and fungi. The relative abundance of beneficial microorganisms such as Sphingomonas, Arthrobacter, RB41, and Micromonospora in rhizosphere soil was increased, while the relative abundance of pathogenic microorganisms such as Aspergillus, Neocosmospora, and Rhizoctonia was decreased.
