Abstract

sp. strain CWF10, an aerobic gram-negative, oval-shaped and motile bacterium, was isolated from the lateritic agricultural soil of Madhya Pradesh, India. The draft genome of the isolate is 5.7 Mb in size, consisting of 14 contigs with 65.09% G+C content. Average nucleotide identity (94.66%) and digital DNA-DNA hybridization (62%) calculation with the closest reference strains underpin the bacterium as a potential novel species. The bacterium has a plethora of plant growth-promoting genes that point towards the potential ability to enhance available nitrogen and biosynthesis of folic acid, among others. Siderophores such as vibrioferrin and crochelin A are also present in the genome and are known to regulate iron uptake. Overall, mining the genome of sp. strain CWF10 has revealed the potential of this strain for application in regenerative agriculture and sustaining soil health.

摘要

菌株CWF10是一种需氧革兰氏阴性、椭圆形且具运动性的细菌，从印度中央邦的红土农业土壤中分离得到。该分离株的基因组草图大小为5.7 Mb，由14个重叠群组成，G+C含量为65.09%。与最相近参考菌株的平均核苷酸同一性（94.66%）和数字DNA-DNA杂交（62%）计算结果表明该细菌是一个潜在的新物种。该细菌拥有大量促进植物生长的基因，表明其具有增强有效氮和叶酸生物合成等潜在能力。基因组中还存在如弧菌素和钩菌素A等铁载体，已知它们可调节铁的摄取。总体而言，对菌株CWF10的基因组挖掘揭示了该菌株在再生农业和维持土壤健康方面的应用潜力。
