“…PGPR is important for sustainable crop production and achieving food security (Ajilogba et al, 2022a). PGPR for crop yield and quality increase as well as disease/pathogen control has been extensively studied in many crops such as soybean (Silva et al, 2019;Riviezzi et al, 2021), rice (Raja et al, 2017;Xu et al, 2019), maize (Ke et al, 2019;Olanrewaju and Babalola, 2019a;Liu et al, 2020), wheat (Kumar et al, 2018;Ma et al, 2021), chickpea (Laranjeira et al, 2021;Khalifa et al, 2022), and cowpea (Kanthaiah and Velu, 2019;Kumar et al, 2021).…”

“…Many studies have reported their use in controlling various plant pathogens. For example, by producing the metabolite, wuyiencin, Streptomyces albulus CK-15 controls powdery mildew of cucumber (Yang et al, 2021), while Bacillus (Cui et al, 2019(Cui et al, , 2020Castaldi et 2021), Rhizobium (Wong et al, 2021;Kawaguchi and Noutoshi, 2022), and Pseudomonas (Omoboye et al, 2019;Khalifa et al, 2022) species have been reported in the biocontrol of some plant species. PGPR acts via direct and indirect mechanisms to control plant pathogens.…”

Orphan legumes are now experiencing growing demand due to the constraints on available major food crops. However, due to focus on major food crops, little research has been conducted on orphan legumes compared to major food crops, especially in microbiome application to improve growth and yield. Recent developments have demonstrated the enormous potential of beneficial microbes in growth promotion and resistance to stress and diseases. Hence, the focus of this perspective is to examine the potential of plant growth promoting rhizobacteria (PGPR) to improve Bambara groundnut yield and quality. Further insights into the potential use of PGPR as a biological control agent in the crop are discussed. Finally, three PGPR genera commonly associated with plant growth and disease resistance (Bacillus, Pseudomonas, and Streptomyces) were highlighted as case studies for the growth promotion and disease control in BGN production.

Fusarium wilt, caused by Fusarium oxysporum, is one of the most notorious diseases of cash crops. The use of microbial fungicides is an effective measure for controlling Fusarium wilt, and the genus Bacillus is an important resource for the development of microbial fungicides. Fusaric acid (FA) produced by F. oxysporum can inhibit the growth of Bacillus, thus affecting the control efficacy of microbial fungicides. Therefore, screening FA-tolerant biocontrol Bacillus may help to improve the biocontrol effect on Fusarium wilt. In this study, a method for screening biocontrol agents against Fusarium wilt was established based on tolerance to FA and antagonism against F. oxysporum. Three promising biocontrol bacteria, named B31, F68, and 30833, were obtained to successfully control tomato, watermelon, and cucumber Fusarium wilt. Strains B31, F68, and 30833 were identified as B. velezensis by phylogenetic analysis of the 16S rDNA, gyrB, rpoB, and rpoC gene sequences. Coculture assays revealed that strains B31, F68, and 30833 showed increased tolerance to F. oxysporum and its metabolites compared with B. velezensis strain FZB42. Further experiments confirmed that 10 µg/mL FA completely inhibited the growth of strain FZB42, while strains B31, F68, and 30833 maintained normal growth at 20 µg/mL FA and partial growth at 40 µg/mL FA. Compared with strain FZB42, strains B31, F68, and 30833 exhibited significantly greater tolerance to FA.

“…In this regard, biocontrol agents have emerged as a potential alternative to chemical fungicides to prevent and control various diseases due to their green and pollution-free characteristics (Niem et al, 2020;Huang et al, 2021;Yuan et al, 2022). The antagonistic microorganisms that can inhibit the postharvest diseases of fruits and vegetables include species of Candida, Bacillus, Pseudomonas, yeast, and Wickerhamomyces (Spadaro and Droby, 2016;Kang et al, 2019;Khalifa et al, 2022). Among them, Bacillus has been widely isolated and utilized as an effective biocontrol agent.…”

Sugarcane (Saccharum officinarum L.) may be infected with Apiospora, which can produce the toxin 3-nitropropionic acid (3-NPA) during improper transportation and storage. The consumption of sugarcane that contains 3-NPA can lead to food poisoning. Therefore, this study sought to explore a novel biocontrol agent to prevent and control Apiospora mold. Bacteria were isolated from the soil of healthy sugarcane and identified as Bacillus velezensis T9 through colony morphological, physiological and biochemical characterization and molecular identification. The inhibitory effect of B. velezensis T9 on Apiospora mold on sugarcane was analyzed. Assays of the cell suspension of strain T9 and its cell-free supernatant showed that T9 had significant in vitro antifungal activities against Apiospora arundinis and thus, would be a likely antagonist. Scanning electron microscopy and transmission electron microscopy showed that treatment with T9 significantly distorted the A. arundinis mycelia, perforated the membrane, contracted the vesicles, and decomposed most organelles into irregular fragments. A re-isolation experiment demonstrates the ability of T9 to colonize the sugarcane stems and survive in them. This strain can produce volatile organic compounds (VOCs) that are remarkably strong inhibitors, and it can also form biofilms. Additionally, the cell-free supernatant significantly reduced the ability of A. arundinis to produce 3-NPA and completely inhibited its production at 10%. Therefore, strain T9 is effective at controlling A. arundinis and has the potential for further development as a fungal prevention agent for agricultural products.
