摘要: Background: Trametes trogii is a member of the white-rot fungi family, which has a unique ability to break down recalcitrant lignin polymers to CO2 and water, and they have enormous potential to biodegrade a wide range of toxic environmental pollutants. Because of its industrial potential, the identification of lignin-degrading enzyme systems in Trametes is an important area of research. Development and utilization of industrial value genes are suffering due to deficiency knowledge of genome available for their manipulation. Results: In the present study, Homokaryotic strains of T. trogii S0301 were screened and sequencing by PacBio Sequel II platform. The final draft genome is similar to 39.88 Mb, with a contig N50 size of 2.4 Mb, this was the first genome sequencing and assembly of T. trogii species. Further analyses predicted 14,508 protein-coding genes. Results showed that T. trogii S0301 contains 602 genes encoding CAZymes, include 211 glycoside hydrolase and 117 lignin-degrading family genes, nine laccases related genes. Small subunit ribosomal RNA gene (18S rRNA) sequencing confirms its phylogenetic position. Moreover, T. trogii S0301 has the largest number of cytochromes P450 (CYPs) superfamily genes compare to other fungi. All these results are consistent with enzymatic assays and transcriptome analysis results. We also analyzed other genome characteristics in the T. trogii S0301genome. Conclusion: Here, we present a nearly complete genome for T. trogii S0301, which will help elucidate the biosynthetic pathways of the lignin-degrading enzyme, advancing the discovery, characterization, and modification of novel enzymes from this genus. This genome sequence will provide a valuable reference for the investigation of lignin degradation in the Trametes genus.
