“…The density value of each band was divided by the average band density of the lane to minimize the influence of the loaded DNA concentrations among samples (Zhou et al 2012). The number of DGGE bands, Shannon Wiener index and evenness index were calculated (Ran et al 2021). Permutational analysis of variance (PERMANOVA) was performed to test the effects of phenolic acid on Fusarium community structure based on the Bray-Curtis distance…”

Soil microorganisms play an important role in agricultural ecosystem. However, there is little information about the effects of putative allelochemicals on specific soil microorganisms in vivo. Cucumber seedlings were treated with four concentrations of ferulic and p-hydroxybenzoic acids (0-1.0 μmol g-1 soil) in soil. Effects of ferulic and p-hydroxybenzoic acids on rhizosphere Fusarium community structures and abundance were analyzed by polymerase chain reaction denaturing gradient gel electrophoresis (PCR-DGGE) and real-time PCR techniques, respectively. The results showed that ferulic acid at concentrations of 0.25, 0.5 and 1.0 μmol g-1 soil significantly reduced the number of bands of Fusarium, and ferulic acid at concentrations of 0.5 and 1.0 μmol g-1 soil significantly reduced Shannon Wiener and evenness index of Fusarium community. All concentrations of p-hydroxybenzoic acid changed the community structure of Fusarium, including decreasing the number of bands, Shannon Wiener and evenness index. Ferulic and p-hydroxybenzoic acids at all concentrations significantly promoted the abundance of Fusarium. Ferulic and p-hydroxybenzoic acids at 0.5 μmol g-1 soil had the highest Fusarium abundance among all treatments. These results indicate that four concentrations of ferulic acid had various effects on Fusarium, which was different from p-hydroxybenzoic acid, and this may be related to the cucumber autotoxicity, giving us a further understanding of soil sickness.

“…Residue DNA was extracted from 0.25 g of residue with the Power Soil DNA Isolation Kit (MO BIO Laboratories, Carlsbad, CA, USA) according to the manufacturer's instructions [32]. Each composite residue sample was extracted in triplicate, and the extracted DNA solutions were pooled as described previously [33].…”

(1) Background: Residue degradation plays a very important role in terrestrial ecosystems and residue mixing is the main factor affecting the degradation rates. However, in the agricultural systems, the effect of residue mixing on the degradation of pepper residues and the microbial community in pepper root residues is not clear. (2) Methods: In this study, we added different residues into soil by using double-layered nylon litterbags in culture bottles. The treatments including pepper root (P: Capsicum annuum L.), soybean [S: Glycine max (L.) Merr.] and maize (M: Zea mays L.) residue, as well as mixtures of soybean + pepper (SP), maize + pepper (MP), maize + soybean + pepper (MSP) mixtures. Litterbags were harvested after 7, 14, 28, and 56 days, respectively. Mass loss and nitrogen and phosphorus contents in pepper residue were quantified and bacterial and fungal community levels in pepper residues were analyzed using quantitative PCR and high throughput amplicon sequencing; (3) Results: The study showed that the mass loss and fungal community abundance of pepper root residue in mixtures were higher than P, except day 7. The phosphorus contents in MSP-P and MP-P were significantly lower than that for P at day 28 and day 56. Illumina MiSeq sequencing showed that the presence of maize residue significantly altered the microbial community composition of pepper root pepper. Day 56. (4) Conclusions: Our results suggest that residue mixing changed the microbial community abundance in pepper residue and promoted the degradation of pepper residues compared to pepper residue decomposition alone, especially for mixtures with soybean.

Microbiome plays vital role in the life. Study the microbiome of plants with great impact in the planet can provide significant information to solve many problems. Therefore, finding structural population of plant microbiome needs scientific approach. Revealing the specific biochemical and genetical approaches towards identification of specific population provided the growing bodies of methods and procedures to study and analysis the plant microbiomes. Thus, this mini-review paper presents the summarized of scientific methods for study, identify and structural population analysis of plant microbiome.
