Since expansion of sequencing microbial genomes in 1990’s, it has been known that SM genes are expanded in the microbial genomes far more than those expected before sequencing. For most of the genes, we never have information about the conditions for their expression, thus, probably 90% or more of them have remained unexamined. In order to accelerate analysis and utilization of the unaddressed useful genes, we have developed a platform comprised of NGS (next-generation sequencer), LC/MS and bioinformatics tools specialized for high throughput analysis of multiple fungal genomes. By using the platform, twelve novel fungal genomes can be sequenced within about two weeks by SOLiD 5500 XL. Our in-house pipelines allow quick and accurate analysis of genome, gene modeling, transcriptome and successive prediction of SM gene cluster. Once a compound of interest is detected by any methods including biological, chemical or physical methods, corresponding SM gene cluster can be rapidly predicted typically within a month. We have successfully determined gene clusters of kojic acid, ustiloxin B and other unknown compounds to date. A remarkable feature of our platform is the ability to detect SM gene clusters without a so-called SM core gene such as PKS, NRPS or terpene. This allows us to expand our target SM gene clusters far beyond those already examined. |
