  2. Jeong J, Park B, Park H, Choi I, Kim K. Draft Genome Sequence of Chryseobacterium sp. Strain GSE06, a Biocontrol Endophytic Bacterium Isolated from Cucumber (Cucumis sativus). Genome Announc. 2016;4: pubmed publisher
    ..Here, we present its draft genome sequence, which contains genes related to biocontrol traits, such as colonization, antimicrobial activity, plant growth promotion, and abiotic or biotic stress adaptation. ..
  3. Park H, Park B, Kim H, Park W, Choi I. Draft Genome Sequences of Two Ureolytic Bacteria Isolated from Concrete Block Waste. Genome Announc. 2016;4: pubmed publisher
    ..We sequenced genomes of two ureolytic bacteria, Bacillus sp. JH7 and Sporosarcina sp. HYO08, which were isolated from concrete waste and have a potential for biocementation applications. ..
  4. Min B, Kim S, Oh Y, Kong W, Park H, Cho H, et al. Genomic discovery of the hypsin gene and biosynthetic pathways for terpenoids in Hypsizygus marmoreus. BMC Genomics. 2018;19:789 pubmed publisher
    ..Comparative genome analysis revealed the conserved gene cluster for terpenoid biosynthesis in the genome. These discoveries will further our understanding of the biosynthesis of medicinal bioactive molecules in this edible mushroom. ..
