strain FG106 was isolated from the rhizosphere of tomato plants and identified through morphological analysis, 16S rRNA gene sequencing, and whole-genome sequencing. In vitro and in vivo experiments demonstrated that this strain could control several pathogens on tomato, potato, taro, and strawberry. Volatile and non-volatile metabolites produced by the strain are known to adversely affect the tested pathogens. FG106 showed clear antagonism against , , subsp. , , , , and pv. . FG106 produced proteases and lipases while also inducing high phosphate solubilization, producing siderophores, ammonia, indole acetic acid (IAA), and hydrogen cyanide (HCN) and forming biofilms that promote plant growth and facilitate biocontrol. Genome mining approaches showed that this strain harbors genes related to biocontrol and growth promotion. These results suggest that this bacterial strain provides good protection against pathogens of several agriculturally important plants via direct and indirect modes of action and could thus be a valuable bio-control agent.
菌株FG106从番茄植株根际分离得到，并通过形态学分析、16S rRNA基因测序和全基因组测序进行鉴定。体外和体内实验表明，该菌株可防治番茄、马铃薯、芋头和草莓上的多种病原菌。已知该菌株产生的挥发性和非挥发性代谢产物会对受试病原菌产生不利影响。FG106对[具体病原菌名称1]、[具体病原菌名称2]、[具体病原菌名称3]亚种[具体病原菌名称4]、[具体病原菌名称5]、[具体病原菌名称6]和[具体病原菌名称7] pv. [具体病原菌名称8]表现出明显的拮抗作用。FG106产生蛋白酶和脂肪酶，同时还能高效溶解磷酸盐、产生铁载体、氨、吲哚乙酸（IAA）和氰化氢（HCN），并形成促进植物生长和便于生物防治的生物膜。基因组挖掘方法表明，该菌株含有与生物防治和生长促进相关的基因。这些结果表明，该细菌菌株通过直接和间接作用模式为几种重要农作物的病原菌提供了良好的保护，因此可能是一种有价值的生物防治剂。
