枯草芽孢杆菌/解淀粉芽孢杆菌的一些菌株以其对真菌植物病原体的植物保护活性而闻名。值得注意的是，这是因为它们的遗传潜力可以形成一系列令人印象深刻的抗生素，包括非核糖体脂肽(LPs)。在这里介绍的工作中，我们希望进一步了解这些脂蛋白在枯草杆菌/液化淀粉菌的全球抗真菌活性中的相对作用。 subtilis/amyloliquefaciens为此，进行了一项涉及多个菌株的比较研究，这些菌株对四种不同的植物病原体进行了测试。我们结合了各种方法来进一步证明，这些内毒素的分泌是直接抵御病原体的关键特征，这实际上可以推广到这些物种的所有成员。我们的数据表明，对于每个LP家族，目标物种的功能不同，其真菌毒活性也不同，并且ITURINS和Fengycins的产生受到病原体的调节。我们在根际自然条件下讨论了这些脂多糖在生物防治活动中的相对参与及其生产的调节的数据。
Some isolates of the Bacillus subtilis/amyloliquefaciens species are known for their plant protective activity against fungal phytopathogens. It is notably due to their genetic potential to form an impressive array of antibiotics including non-ribosomal lipopeptides (LPs). In the work presented here, we wanted to gain further insights into the relative role of these LPs in the global antifungal activity of B. subtilis/amyloliquefaciens. To that end, a comparative study was conducted involving multiple strains that were tested against four different phytopathogens. We combined various approaches to further exemplify that secretion of those LPs is a crucial trait in direct pathogen ward off and this can actually be generalized to all members of these species. Our data illustrate that for each LP family, the fungitoxic activity varies in function of the target species and that the production of iturins and fengycins is modulated by the presence of pathogens. Our data on the relative involvement of these LPs in the biocontrol activity and modulation of their production are discussed in the context of natural conditions in the rhizosphere.
