Here, we report the draft genome sequence of Bt Strain S2685-1. It consists of 262 scaffolds with a GC content of 34.89% and a total length of 5,685,503 bp. The assemble analysis shows that there are four replicons in S2685-1, including a circular chromosome of 5,287,484 bp with 6326 ORFs and 5429 CDSs and three circular plasmids, which are named S2685-1P01 (151,717 bp), S2685-1P02 (196,775 bp) and S2685-1P03 (49,527 bp), respectively. The average GC content of the chromosome sequence is 35.08%, while that of the plasmid sequences are 31.86%, 32.23% and 34.89%, respectively. Two crystal genes have been predicted from this strain but they share 100% sequence identity to cry1Ac in HD73. It also had been identified with high larvacidal toxicity against Helicoverpa zea in S2685-1.
