Lactiplantibacillus plantarum HQ-3 was isolated from fermented soybean and has been validated in vitro for potential probiotic characteristics.In the study, high-throughput sequencing was employed to conduct whole-genome sequencing of HQ-3, and its potential probiotic functions were explored based on genomic analysis.The total genome length of HQ-3 was 3 422 620 bp, with a GC content of 44.41%;the genome contains five plasmids, and a total of 3 283 coding genes were predicted.Genes were annotated in the GO, KEGG, COG, CAZy, and CARD databases numbered 3 968, 3 238, 2 888, 128, and 2, respectively.Genomic analysis revealed that HQ-3 contains genes associated with bile salt hydrolase (4 genes), acid tolerance (9 genes), adhesion (1 gene), bacteriocin production (6 genes), carbohydrate transport (20 genes), heat shock proteins (8 genes), and cold shock proteins (3 genes).In conclusion, the whole-genome sequencing and potential probiotic function analysis of HQ-3 could provide theoretical guidance for the development of its probiotic properties.
