Abstract

Here we report the complete genome sequence of a plant growth-promoting rhizobacterium (PGPR), Paenibacillus polymyxa SQR-21, which consists of one circular chromosome of 5,828,438 bp with 5,024 coding sequences (CDS). The data presented highlight multiple sets of functional genes associated with its plant-beneficial characteristics.

Highlights

We report the complete genome sequence of a plant growth-promoting rhizobacterium (PGPR), Paenibacillus polymyxa SQR-21, which consists of one circular chromosome of 5,828,438 bp with 5,024 coding sequences (CDS)
P. polymyxa SQR-21 was naturally isolated from watermelon rhizosphere
As an outstanding PGPR strain with the ability to produce various antibiotics [16, 17] and colonize rhizospheres [18], SQR-21 has been widely exploited in commercial biofertilizers for plant growth promotion and biological control of soilborne plant pathogens [19, 20]

Summary

Introduction

We report the complete genome sequence of a plant growth-promoting rhizobacterium (PGPR), Paenibacillus polymyxa SQR-21, which consists of one circular chromosome of 5,828,438 bp with 5,024 coding sequences (CDS). Paenibacillus polymyxa (formerly Bacillus polymyxa), a Grampositive, sporulating bacterium, is considered to be a plant growth-promoting rhizobacterium (PGPR) [1, 2]. Isolated from various environmental samples [3, 4], P. polymyxa has been widely applied in agriculture, industry, medicine, and environmental remediation [5,6,7,8,9,10,11,12].
