“…The rhizosphere bacteria or plant endophytes may protect plant tissues toward SRP [ 99 , 111 , 112 , 113 , 114 ]. Most of the research on the selection of strains inhibiting the growth of SRP is focused on their mode of action, which includes production of antimicrobials, competition for nutrient and iron ions [ 115 , 116 , 117 , 118 , 119 , 120 ], and interference with the cell-to cell communication (QS mechanism–see below) of the pathogens [ 113 , 121 , 122 , 123 , 124 ]. Many of these potential BCAs contribute to plant tissue protection via a combination of antagonistic activities, e.g., production of antimicrobials, induction of systemic resistance in plants, and interfering in pathogens’ cell-to-cell communication [ 108 , 115 ].…”

The majority of research on biological control concerns crop plants (e.g., potato, Chinese cabbage); however, BCAs have also been developed for the control of bacteria in ornamentals [ 119 , 124 ]. Jafra et al [ 124 ] selected Dickeya zeae antagonists, which included, among others, the strains of Rahnella aquatilis and Erwinia persicina from hyacinth bulb tissues.…”

“…Although the number of potential SRP biocontrol strains studied under laboratory condition is growing, there is a limited number of studies evaluating their biocontrol potential under greenhouse, field, or storage conditions [ 117 , 118 , 119 , 120 , 125 , 126 ], and even less data on the use of FPs in studies of plant colonization efficiency, their use on/in plants, and effectiveness in inhibiting pathogen activity. Notwithstanding, SRPs, as well as the bacterial antagonists of Pectobacterium spp.…”

Biosensors Used for Epifluorescence and Confocal Laser Scanning Microscopies to Study Dickeya and Pectobacterium Virulence and Biocontrol

Promoter-probe vectors carrying fluorescent protein-reporter genes are powerful tools used to study microbial ecology, epidemiology, and etiology. In addition, they provide direct visual evidence of molecular interactions related to cell physiology and metabolism. Knowledge and advances carried out thanks to the construction of soft-rot Pectobacteriaceae biosensors, often inoculated in potato Solanum tuberosum, are discussed in this review. Under epifluorescence and confocal laser scanning microscopies, Dickeya and Pectobacterium-tagged strains managed to monitor in situ bacterial viability, microcolony and biofilm formation, and colonization of infected plant organs, as well as disease symptoms, such as cell-wall lysis and their suppression by biocontrol antagonists. The use of dual-colored reporters encoding the first fluorophore expressed from a constitutive promoter as a cell tag, while a second was used as a regulator-based reporter system, was also used to simultaneously visualize bacterial spread and activity. This revealed the chronology of events leading to tuber maceration and quorum-sensing communication, in addition to the disruption of the latter by biocontrol agents. The promising potential of these fluorescent biosensors should make it possible to apprehend other activities, such as subcellular localization of key proteins involved in bacterial virulence in planta, in the near future.

The application and promotion of biological control agents are limited because of poor efficacy and unstable performance in the field. Screening microorganisms with high antagonistic activity, effective adaptability, and high field-survival should be prospected. Myxobacteria are soil predatory bacteria with wide adaptability, which are considered as good antagonists. Here, we report a myxobacterium strain M34 isolated from subtropical forest soil in South China using the Escherichia coli baiting method. Based on the morphological observation, physiological test, biochemical characteristics, 16S rRNA gene sequence, and genomic data, strain M34 was identified as a novel genus and novel species, representing a new clade of Myxococcaceae, for which the name Citreicoccus inhibens gen. nov. sp. nov. is proposed (type strain M34T = GDMCC 1.2275T = KCTC 82453T). The typical features of M34, including fruiting body formation and extracellular fibrillar interconnection, indicated by microscopic observations, contributed to cell adaption in different environments. Furthermore, the strain showed antifungal activity against phytopathogenic fungi and predatory activity to both Gram-negative and Gram-positive phytopathogenic bacteria. The bioprotective mechanisms are attributed to the presence of pyrrolnitrin and derivative with antifungal activity and the extracellular proteins with lytic activity against pathogenic bacteria. Due to its multiple beneficial traits, strain M34 has the potential to be developed into a versatile biocontrol agent for the management of both fungal and bacterial phytopathogens.
