sp. strain MS389, an endophytic bacterium, was isolated from a healthy soybean plant growing adjacent to a patch of plants affected by charcoal rot disease, caused by the fungal pathogen . Preliminary studies demonstrated that strain MS389 possesses antimicrobial activities against multiple plant pathogens. sp. strain MS389 was found to have three circular chromosomes of 3,563,380 bp, 3,002,449 bp, and 1,180,421 bp in size, respectively. The 7,746,250-bp genome, with 66.73% G+C content, harbors 6,756 protein coding genes in the predicted 6,985 genes. In total, 18 rRNAs, 68 tRNAs, and four ncRNAs were identified and 139 pseudogenes were annotated as well. The findings of this study will provide valuable data to explore the antimicrobial mechanisms of the endophytic bacterial strain.
从一株健康大豆植株中分离到一株内生细菌 sp. 菌株 MS389，该植株生长在受炭腐病影响的植株附近，炭腐病是由真菌病原体引起的。初步研究表明，菌株 MS389 对多种植物病原体具有抗菌活性。发现 sp. 菌株 MS389 有三个大小分别为 3,563,380 bp、3,002,449 bp 和 1,180,421 bp 的圆形染色体。该 7,746,250-bp 基因组，GC 含量为 66.73%，在预测的 6,985 个基因中包含 6,756 个蛋白质编码基因。总共鉴定了 18 个 rRNAs、68 个 tRNAs 和 4 个 ncRNAs，并注释了 139 个假基因。这项研究的结果将为探索内生细菌菌株的抗菌机制提供有价值的数据。
