Characterization of candidate genes involved in halotolerance using high-throughput omics in the halotolerant bacterium Virgibacillus chiguensis.

We previously used whole-genome sequencing and Tn5 transposon mutagenesis to identify 16 critical genes involved in the halotolerance of Halomonas beimenensis, a species in the phylum Proteobacteria. In this present study, we sought to determine if orthologous genes in another phylum are also critic...

description We previously used whole-genome sequencing and Tn5 transposon mutagenesis to identify 16 critical genes involved in the halotolerance of Halomonas beimenensis, a species in the phylum Proteobacteria. In this present study, we sought to determine if orthologous genes in another phylum are also critical for halotolerance. Virgibacillus spp. are halotolerant species that can survive in high-saline environments. Some Virgibacillus species are used in different aspects of food processing, compatible solute synthesis, proteinase production, and wastewater treatment. However, genomic information on Virgibacillus chiguensis is incomplete. We assembled a draft V. chiguensis strain NTU-102 genome based on high-throughput next-generation sequencing (NGS) and used transcriptomic profiling to examine the high-saline response in V. chiguensis. The V. chiguensis draft genome is approximately 4.09 Mbp long and contains 4,166 genes. The expression profiles of bacteria grown in 5% and 20% NaCl conditions and the corresponding Gene Ontology (GO) and clusters of orthologous groups (COG) categories were also analyzed in this study. We compared the expression levels of these 16 orthologs of halotolerance-related genes in V. chiguensis and H. beimenensis. Interestingly, the expression of 7 of the 16 genes, including trkA2, smpB, nadA, mtnN2, rfbP, lon, and atpC, was consistent with that in H. beimenensis, suggesting that these genes have conserved functions in different phyla. The omics data were helpful in exploring the mechanism of saline adaptation in V. chiguensis, and our results indicate that these 7 orthologs may serve as biomarkers for future screening of halotolerant species in the future.
