“…This might be due to the fact that HR soil had low level of pathogen, thus suggesting that pathogen densities were not high enough to activate the rhizosphere defense system. Moreover, we also found more documented plant-beneficial microorganisms that showed negative correlation with Ralstonia such as Burkholderia [32], Actinospica, and…”

Background The soil disease-suppressiveness may depend on complex interactions between pathogens and microbiome in response to limiting nutrients. However, these interactions remain poorly understood. Thus, we investigated the significance of soil available phosphorus (AP) in modulating pathogen-microbiome interactions for the emergence or suppression of peanut wilt using receiver operating characteristic curve (ROC) analysis and structural equation modeling (SEM) approaches. Results We observed significant differences in the relative abundance of pathogenic and beneficial microbes, alpha- and beta-diversity indices between disease-conducive and -suppressive soils. The pathogenic ( Ralstonia) and beneficial ( Burkholderia and Bacillus ) taxa dominated the rhizosphere of wilted and healthy peanut plants. The rhizosphere of healthy rather than wilted plants showed significantly higher microbial biodiversity. Moreover, co-occurrences between Ralstonia and microbiome species were highly positive and negative in the disease-conducive and -suppressive soil, respectively, thus predicting facilitative ( Rudaea ) and suppressive ( Burkholderia , Enterobacter , Bacillus ) role of indigenous microbes in Ralstonia invasion in soil. Moreover, both ROC and SEM analyses revealed that Ralstonia invaded rhizospheric microbial networks and caused peanut wilt, very likely by competently utilizing soil phosphorus under copiotrophic (high AP) than oligotrophic (low AP) conditions. Conclusion Our results suggest the importance of soil phosphorus availability in altering the interactions between pathobiome and beneficial microbiome. Our study concludes that feeding soil with labile nutrients could deplete microbial biodiversity and interactions while paving the way for pathogen invasion.

“…campestris was significantly reduced upon treatment with bacteriophage as well [226]. Additionally, phage cocktails have been employed against Ralstonia solanacearum in bananas [227]. Several recent reviews have covered advancements and future prospective of using bacteriophages for the management of bacterial plant diseases [221,[228][229][230][231].…”

Extended overuse and misuse of antibiotics and other antibacterial agents has resulted in an antimicrobial resistance crisis. Bacteriophages, viruses that infect bacteria, have emerged as a legitimate alternative antibacterial agent with a wide scope of applications which continue to be discovered and refined. However, the potential of some bacteriophages to aid in the acquisition, maintenance, and dissemination of negatively associated bacterial genes, including resistance and virulence genes, through transduction is of concern and requires deeper understanding in order to be properly addressed. In particular, their ability to interact with mobile genetic elements such as plasmids, genomic islands, and integrative conjugative elements (ICEs) enables bacteriophages to contribute greatly to bacterial evolution. Nonetheless, bacteriophages have the potential to be used as therapeutic and biocontrol agents within medical, agricultural, and food processing settings, against bacteria in both planktonic and biofilm environments. Additionally, bacteriophages have been deployed in developing rapid, sensitive, and specific biosensors for various bacterial targets. Intriguingly, their bioengineering capabilities show great promise in improving their adaptability and effectiveness as biocontrol and detection tools. This review aims to provide a balanced perspective on bacteriophages by outlining advantages, challenges, and future steps needed in order to boost their therapeutic and biocontrol potential, while also providing insight on their potential role in contributing to bacterial evolution and survival.

“…Those examples were included in Table 1. The phage mixtures were used to control a variety of bacterial plant pathogens such as R. solanacearum (Ramírez et al, 2020;Wang et al, 2019;Wei et al, 2017), Xanthomonas sp. (Chae et al, 2014;Ibrahim et al, 2017;Tewfike and Desoky, 2015), and P. carotovorum sp.…”

In nature, plants are always under the threat of pests and diseases. Pathogenic bacteria are one of the major pathogen types to cause diseases in diverse plants, resulting in negative effects on plant growth and crop yield. Chemical bactericides and antibiotics have been used as major approaches for controlling bacterial plant diseases in the field or greenhouse. However, the appearance of resistant bacteria to common antibiotics and bactericides as well as their potential negative effects on environment and human health demands bacteriologists to develop alternative control agents. Bacteriophages, the viruses that can infect and kill only target bacteria very specifically, have been demonstrated as potential agents, which may have no negative effects on environment and human health. Many bacteriophages have been isolated against diverse plantpathogenic bacteria, and many studies have shown to efficiently manage the disease development in both controlled and open conditions such as greenhouse and field. Moreover, the specificity of bacteriophages to certain bacterial species has been applied to develop detection tools for the diagnosis of plant-pathogenic bacteria. In this paper, we summarize the promising results from greenhouse or field experiments with bacteriophages to manage diseases caused by plant-pathogenic bacteria. In addition, we summarize the usage of bacteriophages for the specific detection of plant-pathogenic bacteria.
