“…The results from the present study also showed that the high ability of the culture filtrate of P. lilacinum at all tested concentrations to reduce both the incidence and severity of orange green mould during 7 days of incubation at 25°C, which was consistent with the results of in vitro assays. Our results agree with previous studies that confirm the potential of P. lilacinum and its culture filtrate in biocontrol of plant diseases, such as stem rot in oilseed rape (Yang et al 2015), Verticillium wilt in eggplant (Lan et al 2017), white mould in common bean (Elsherbiny et al 2019) and Phytophthora blight in pepper (Hu et al 2020). In addition, P. lilacinum has remarkable effects on plant growth promotion.…”

Aims: The present study evaluated, for the first time, the inhibitory effects of the filtrate of Purpureocillium lilacinum against Penicillium digitatum. Methods and Results: No direct contact between P. lilacinum and P. digitatum was observed during the dual culture test and the inhibition zone was 6Á1 mm. The filtrate of P. lilacinum completely inhibited P. digitatum growth and spore germination at the concentration of 64%. The filtrate increased the permeability of the cell membrane and the content of MDA in P. digitatum. The ergosterol content in P. digitatum was strongly inhibited at 32% by 81Á1%. The green mould incidence and severity in filtrate-treated fruit at 64% were 71Á7 and 80Á7% lower than in the control, respectively. The filtrate enhanced the activity of PAL, PPO and POD enzymes in orange fruit. The POD and PAL gene expression levels were significantly upregulated in the fruit treated with the filtrate. Conclusions: This study indicated that the antifungal mechanism of P. lilacinum filtrate against P. digitatum is mainly by the damage of the fungal cell membrane and its components. Significance and Impact of the Study: This work provides the pioneer evidence on the application of P. lilacinum filtrate as a novel biocontrol agent for orange green mould.

“…Additional studies showed that complex biofungicides caused both disease suppression and the promotion of plant growth [ 17 , 18 ]. However, the possibility of competition for space and nutrients among different antifungal agents merits consideration [ 19 ]. More research needs to be conducted to explore the optimal combination of different antagonistic bacteria and the effects of the microbial complexes.…”

Peach brown rot caused by Monilinia fructicola is one of the most economically destructive diseases of peach (Prunus persica L.) in some orchards of China. Biocontrol is a significant strategy that exhibits strong levels of control and ecologically sound concepts in disease management. The purpose of this study was to investigate the combined suppressive effects of three endophytic bacterial strains (xj-14, xj-15, and xj-16) and two soil rhizosphere bacterial strains (xj-A and xj-C) that were shown to have strong inhibitory activity toward M. fructicola in our previous study. The optimal strains and the optimized combination of strains were determined. The combination of strains xj-15 and xj-C inhibited M. fructicola more intensively for a longer period of time. Following the application of 1 × 109 CFU/mL bacterial complex to the fruits, leaves, and shoots of peach trees infected with M. fructicola, the rate of inhibition reached 73.80%, 83.33%, and 90.43%, respectively. A pot experiment using lettuce (Lactuca sativa) showed that inoculation with the bacterial complex significantly increased the growth of seedlings. In this study, some compound bacteria were more effective than those in previous study in suppressing disease and promoting growth, which have the potential to be further applied in the field.

“…As a special glycoprotein, which was quantified as the glomalin-related soil protein (GRSP) in soils, glomalin can adhere to organic materials and bind to clay particles, sand and silt, thereby enhancing soil stability and increasing carbon (C) storage (Rillig, 2004;Zhang, He, Zhao, Zhang, & Xu, 2017). Furthermore, AM fungi have benefits for the productive functions of agroecosystems (Smith & Read, 2008), such as protecting plants from soil pathogens and improving their resistance to abiotic stresses (Hu et al, 2014(Hu et al, , 2020. From this perspective, AM fungi are of high value for the maintenance of agroecosystem functions to increase sustainability (Rillig et al, 2019).…”

Organic amendments are powerful tools for mitigating land degradation, improving soil fertility and biodiversity. Nevertheless, changes in the diversity and activity of arbuscular mycorrhizal (AM) fungi during the initial period of soil restoration under different organic amendments (e.g., crop residues and livestock manure) remains poorly understood despite their growing roles in improving soil sustainability. We conducted a six-month experiment with the application of rice straw (RS), horse manure (HM), and both amendments (RH) to an artificially degraded field in Eastern China, and the AM fungal community structure was assessed through Illumina sequencing. The dominance (35.2%) of the identified operational taxonomic units (OTUs) belonged to Glomus, whereas the majority (66.0%) of the recovered sequence reads belonged to Paraglomus. Although no notable changes in AM fungal abundance were observed, the relative abundance of Claroideoglomus significantly increased (p < .05) to 4.3% in the HM-treated soil compared with that in the control (0.1%), and Acaulospora was only detected in the three treated soils. In addition to shaping AM fungal communities, the RH appeared to be the strongest treatment for increasing AM fungal diversity, alkaline phosphatase activity, and glomalin-related soil protein (GRSP) concentrations, and these parameters were positively correlated (p < .05) with edaphic factors, notably the organic carbon concentration. Furthermore, GRSP could be used as an ecological indicator of AM fungal functioning. This study highlights that the combined application of crop residues and livestock manure could have synergistic effects that help to ameliorate the community structure and diversity of AM fungi in degraded fields.
