Bacillus pumilus ZB201701 is a rhizobacterium with the potential to promote plant growth and tolerance to drought and salinity stress. We herein present the complete genome sequence of the Gram-positive bacterium B. pumilus ZB201701, which consists of a linear chromosome with 3,640,542 base pairs, 3,608 protein-coding sequences, 24 ribosomal RNAs, and 80 transfer RNAs. Genome analyses using bioinformatics revealed some of the putative gene clusters involved in defense mechanisms. In addition, activity analyses of the strain under salt and simulated drought stress suggested its potential tolerance to abiotic stress. Plant growth-promoting bacteria-based experiments indicated that the strain promotes the salt tolerance of maize. The complete genome of B. pumilus ZB201701 provides valuable insights into rhizobacteria-mediated salt and drought tolerance and rhizobacteria-based solutions for abiotic stress in agriculture.
短小芽孢杆菌 ZB201701 是一种具有促进植物生长和耐受干旱和盐胁迫能力的根际细菌。本文呈现了革兰氏阳性细菌短小芽孢杆菌 ZB201701 的完整基因组序列，该线性染色体由 3640542 个碱基对、3608 个蛋白质编码序列、24 个核糖体 RNA 和 80 个转移 RNA 组成。使用生物信息学对基因组进行分析，揭示了一些与防御机制相关的假定基因簇。此外，该菌株在盐和模拟干旱胁迫下的活性分析表明其具有潜在的抗非生物胁迫能力。基于植物促生菌的实验表明，该菌株可促进玉米的耐盐性。短小芽孢杆菌 ZB201701 的完整基因组为根际细菌介导的盐和干旱耐受性以及基于根际细菌的农业非生物胁迫解决方案提供了有价值的见解。
