We have sequenced the whole genome of sp. 6(4) isolated from tomato roots that presents antifungal activity against phytopathogenic fungi, mainly . The genome has almost 7 Mb and 3368 hypothetical proteins that were analysed and characterized in Uniprot with the emphasis on biological compounds. Multilocus sequence typing (MLST) analyses were performed in an effort to characterize and identify this isolate, resulting in a new sequence type (ST), classified as ST64. Phenetic and phylogenetic trees were constructed to investigate sp. 6(4) evolution and sequence similarity, and the isolate is a strain closer to and . It is known that the genus possess huge metabolic capacity with the presence of cryptic genes. These genes are usually present in clusters, which are responsible for the production of diverse natural products, mainly antibiotics. In addition, 6(4) showed 11 biosynthetic gene clusters through antiSMASH, including 3 polyketide synthase (PKS) and non-ribosomal peptide synthase (NRPS) type clusters.
我们对从番茄根部分离出的sp. 6(4)的全基因组进行了测序,该菌株对植物病原真菌具有抗真菌活性,主要针对[此处原文缺失具体真菌名称]。该基因组大小近7兆碱基,包含3368个假定蛋白,已在UniProt中对其进行了分析和表征,重点是生物化合物。进行了多位点序列分型(MLST)分析以表征和鉴定该分离株,结果产生了一种新的序列类型(ST),分类为ST64。构建了表型树和系统发育树以研究sp. 6(4)的进化和序列相似性,该分离株是一种更接近[此处原文缺失具体菌株名称]和[此处原文缺失具体菌株名称]的菌株。已知[此处原文缺失具体属名]属具有巨大的代谢能力,存在隐秘基因。这些基因通常成簇存在,负责产生多种天然产物,主要是抗生素。此外,通过antiSMASH分析,6(4)显示出11个生物合成基因簇,包括3个聚酮合酶(PKS)和非核糖体肽合成酶(NRPS)类型的簇。
