Data on annotation and analysis of genome sequence of YSY-1.2, a promising chitinase-producing, plant-growth-promoting, and biocontrol agent.

The bacterium YSY-1.2 was recently isolated from soil collected from Yok Don National Park in Vietnam. Previous experiments showed this bacterium possesses high chitin-degrading activity, plant-growth promotion, and biocontrol capacity. Here, we report the draft genome sequence of strain YSY-1.2 for further characterizations related to crop production. The genome sequencing was performed using the DNBSeq-G99 with the Illumina platform. The draft genome of YSY-1.2 has 8,240,519 bp in length and comprises 135 contigs. It has an N50 of 315,408 bp and a GC% of 52.8%. The genome contains 7498 protein-coding genes, 87 tRNA genes, and 1 rRNA gene. Among the protein-coding sequences, 6610 were assigned by COG, while 3230 were assigned by KEGG. The genome possesses at least 61 genes involved in environmental adaptation and plant growth promotion. Additionally; there are 258 carbohydrate-active enzymes deduced from the genome; among them, at least 14 may contribute to the biocontrol capacity. The chitin-degrading system of strain YSY-1.2 contains 16 chitinolytic enzymes, comprising 10 chitinases, 4 β--acetylhexosaminidases, and 2 auxiliary activities. Furthermore, 32 gene clusters encoding antimicrobial metabolites were identified from the genome, with 17 showing no sequence similarities to reported clusters. Data provide an insight into the genomic information of strain YSY-1.2 and could lead to valuable further explorations and applications in crop production. This is the first report describing the genome sequence of isolated from Vietnam.
