Two bacteria, MDJK11 and MDJK44, which are potential plant growth-promoting rhizobacteria against pathogenic fungi were isolated from the rhizosphere soil of peony in Shandong, China. Their biological characteristics and complete genome sequences were reported in this study. The total genome size of MDJK11 was only 8.14 Mb with 6,550 protein-coding genes and a high GC content of 72.8 mol%. The MDJK44 genome comprises a 9.62 Mb chromosome with 72.1 mol% GC content, 7,285 protein-coding genes, and two plasmids. Some gene sequences in these two genomes were analyzed to be heterologously obtained by horizontal transfer. Gene or gene cluster candidates responding to secondary metabolites production, antimicrobial activities, and plant growth-promoting capacities were also analyzed in this paper. The genomic information and biological characteristics will facilitate the understanding and application of and species as biocontrol agents in future agriculture.
从中国山东牡丹根际土壤中分离到两株具有拮抗真菌活性的潜在植物促生根际细菌 MDJK11 和 MDJK44。本研究对它们的生物学特性和全基因组序列进行了报道。MDJK11 的全基因组大小仅为 8.14 Mb，包含 6550 个蛋白编码基因和 72.8 mol% 的高 GC 含量。MDJK44 基因组由一个 9.62 Mb 的染色体组成，GC 含量为 72.1 mol%，包含 7215 个蛋白编码基因和两个质粒。对这两个基因组中的一些基因序列进行分析，发现它们是通过水平转移获得的异源基因。本文还分析了与次生代谢产物产生、抗菌活性和植物促生能力相关的基因或基因簇候选物。这些基因组信息和生物学特性将有助于未来农业中作为生物防治剂的 和 种的理解和应用。
