Microbial natural products among other functions they play a vital role in the disease prevention in humans, animals and plants. Pseudomonas parafulva CRS01-1 is a broad-spectrum antagonistic bacterium present in plants. However, no natural products have been isolated from this strain till date. Corresponding biosynthetic gene clusters to natural products is an effective method for bioprospecting, for which, genome manipulation tools are essential. We previously developed Pseudomonas-specific phage-derived homologous recombination systems for genetic engineering in four Pseudomonas species. Herein, we report the application of these recombineering systems in Pseudomonas parafulva CRS01-1, along with structural elucidation and bioactivity evaluation of natural products. The Pseudomonas recombineering toolbox established before in different four species is efficient for genome mining and bioactive metabolite discovery from more distant species.

重组工程促进了副黄假单胞菌天然产物生物合成途径的发现

微生物天然产物除其他功能外,它们在人类、动物和植物的疾病预防中起着至关重要的作用。Pseudomonas parafulva CRS01-1 是一种存在于植物中的广谱拮抗细菌。然而,迄今为止,尚未从该菌株中分离出天然产物。将生物合成基因簇与天然产物对应起来是一种有效的生物勘探方法,为此,基因组操作工具必不可少。我们之前开发了假单胞菌特异性噬菌体同源重组系统,用于四种假单胞菌属物种的基因工程。在此,我们报告了这些重组工程系统在Pseudomonas parafulva 中的应用CRS01-1,以及天然产物的结构解析和生物活性评估。之前在不同四种物种中建立的假单胞菌重组工程工具箱对于基因组挖掘和更远距离物种的生物活性代谢物发现是有效的。
