镰刀菌属包括与农业相关的植物病原性物种。尖孢镰刀菌引起番茄枯萎病，造成显著的产量损失。使用农药防治番茄枯萎病对环境不友好。芽孢杆菌属物种作为生物防治剂，提供了一种安全和可持续的手段来控制镰刀菌诱导的植物病害。本文研究了从光叶牧豆根瘤中分离的蜡状芽孢杆菌MH 778713对番茄枯萎病的保护作用。 蜡样芽孢杆菌MH 778713及其挥发物对F.在离体和体内试验中，尖孢霉和刺激番茄幼苗生长。温室番茄植株接种B.蜡状芽孢杆菌MH 778713，枯萎率由96%下降到12%，对枯萎病有较好的防治效果。在B产生的代谢产物中。蜡状芽孢杆菌MH 778713、三十一烷和2，4-二叔丁基苯酚促进番茄幼苗生长并对目标病原菌表现出抗真菌活性。接种B.蜡状芽孢杆菌MH 778713对番茄幼苗的作用有助于番茄对枯萎病的控制，提示了B的潜力。蜡状芽孢杆菌MH 778713作为生防剂。这些结果补充了我们以前对B耐铬性和生物修复特性的研究。蜡状芽孢杆菌MH 778713，强调这种耐金属微生物促进作物生长和抗病性的潜力。
The genus Fusarium comprises plant pathogenic species with agricultural relevance. Fusarium oxysporum causes tomato wilt disease with significant production losses. The use of agrochemicals to control the Fusarium wilt of tomato is not environmentally friendly. Bacillus species, as biocontrol agents, provide a safe and sustainable means to control Fusarium‐induced plant diseases. In this study, the ability of Bacillus cereus MH778713, a strain isolated from root nodules of Prosopis laevigata, to protect tomato plants against Fusarium wilt was evaluated. Bacillus cereus MH778713 and its volatiles inhibited the radial growth of F. oxysporum and stimulated tomato seedling growth in in vitro and in vivo tests. When tomato plants growing in the greenhouse were inoculated with B. cereus MH778713, the percentage of wilted plants decreased from 96% to 12%, indicating an effective crop protection against Fusarium wilt. Among the metabolites produced by B. cereus MH778713, hentriacontane and 2,4‐di‐tert‐butylphenol promoted tomato seedling growth and showed antifungal activity against the target pathogen. The inoculation of B. cereus MH778713 on tomato seedlings helped plants to manage Fusarium wilt, suggesting the potential of B. cereus MH778713 as a biocontrol agent. These results complement our previous studies on chromium tolerance and bioremediation traits of B. cereus MH778713 by highlighting the potential of this metal‐resistant micro‐organism to boost crop growth and disease resistance.
