Pseudarthrobacter phenanthrenivorans strain MHSD1 is a bacterial endophyte isolated from sterilized leaves of Pellaea calomelanos, a medicinal plant capable of growing in arid environments. Here, we report the draft genome sequence and annotation of this bacterial endophyte. The draft genome sequence of P. phenanthrenivorans strain MHSD1 has 4 450 468 bp with a G + C content of 65.30%. The National Center for Biotechnology Information Prokaryotic Genome Annotation Pipeline identified a total of 4004 protein-coding genes, 56 genes coding for RNAs, and 82 pseudogenes. Biosynthesis pathways for various phytohormones such as auxin, salicylic acid, ethylene, cytokinin, jasmonic acid, abscisic acid, and gibberellins were identified. Putative genes involved in various characteristics of bacterial endophyte lifestyle such as transport, motility, adhesion, membrane proteins, secretion and delivery systems, plant cell wall modification, and detoxification were identified. Phylogenomic analysis showed P. phenanthrenivorans strain MHSD1 to be a subspecies of P. phenanthrenivorans Sphe3.

Pseudarthrobacter phenanthrenivorans菌株 MHSD1 是从Pellaea calomelanos的无菌叶子中分离出来的细菌内生菌，Pellaea calomelanos 是一种能够在干旱环境中生长的药用植物。在这里，我们报告了这种细菌内生菌的基因组序列草案和注释。P. phenanthrenivorans MHSD1菌株基因组草图序列为4 450 468 bp，G+C含量为65.30%。国家生物技术信息中心原核基因组注释管道共鉴定出4004个蛋白质编码基因、56个RNA编码基因和82个假基因。确定了各种植物激素（例如生长素、水杨酸、乙烯、细胞分裂素、茉莉酸、脱落酸和赤霉素）的生物合成途径。鉴定了涉及细菌内生菌生活方式的各种特征的推定基因，例如运输、运动、粘附、膜蛋白、分泌和递送系统、植物细胞壁修饰和解毒。系统发育分析显示P. phenanthrenivorans菌株 MHSD1 是P. phenanthrenivorans Sphe3 的一个亚种。
