Bacillus amyloliquefaciens L-S60, a gram-positive plant-associated bacterium, which could stimulate plant growth and shows strong antifungal function, was isolated from the turfy soil in Beijing, China. The genome of B. amyloliquefaciens L-S60 comprises a 3903,017bp long circular chromosome that consists of 3909 protein-coding genes and 117 RNA genes. Based on genomic analysis, we identified gene clusters responsible for the biosynthesis of numerous bioactive metabolites with well-established in-vitro activity such as surfactin, iturin and fengycins. Additionally, we also found functionally related genes in the genome of L-S60, which play key roles in the process of plant growth promotion hormone secretion, biofilm formation and volatile compounds production.
解淀粉芽孢杆菌L-S60是一种革兰氏阳性植物相关细菌,可刺激植物生长并具有很强的抗真菌功能,它是从中国北京的草炭土中分离得到的。解淀粉芽孢杆菌L-S60的基因组由一条3903017bp长的环状染色体组成,该染色体包含3909个蛋白质编码基因和117个RNA基因。基于基因组分析,我们鉴定出了负责多种具有体外活性的生物活性代谢产物(如表面活性素、伊枯草菌素和丰原素)生物合成的基因簇。此外,我们还在L-S60的基因组中发现了功能相关基因,这些基因在植物生长促进激素分泌、生物膜形成和挥发性化合物产生过程中发挥着关键作用。
