sp. DC2 is an endophytic fungus that was isolated from the stem of (L.) G. Don in Hanoi, Vietnam and is capable of producing vinca alkaloids. This study utilizes the PacBio Sequel technology to completely sequence the whole genome of sp. DC2The genome study revealed that DC2 contains a total of 34.58 Mb spanned by 156 contigs, with a GC content of 46.5%. The identification and prediction of functional protein-coding genes, tRNA, and rRNA were comprehensively predicted and highly annotated using various BLAST databases, including non-redundant (Nr) protein sequence, Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), Clusters of Orthologous Groups (COG), and Carbohydrate-Active Enzymes (CAZy) databases. The genome of DC2 has a total of 149, 227, 65, 153, 53, and 6 genes responsible for cellulose, hemicellulose, lignin, pectin, chitin, starch, and inulin degradation, respectively. The Antibiotics and Secondary Metabolites Analysis Shell (AntiSMASH) analyses revealed that strain DC2 possesses 20 biosynthetic gene clusters responsible for producing secondary metabolites. The strain DC2 has also been found to harbor the gene encoding aromatic L-amino acid decarboxylase enzyme. Conclusively, this study has provided a comprehensive understanding of the processes involved in secondary metabolites and the ability of the sp. DC2 strain to degrade plant cell walls.
DC2菌株是一种从越南河内的(L.)G. Don茎中分离出的内生真菌,能够产生长春花生物碱。本研究利用PacBio Sequel技术对DC2菌株的全基因组进行了完整测序。基因组研究表明,DC2的基因组全长34.58 Mb,由156个重叠群组成,GC含量为46.5%。使用包括非冗余(Nr)蛋白质序列、基因本体论(GO)、京都基因与基因组百科全书(KEGG)、直系同源簇(COG)和碳水化合物活性酶(CAZy)数据库在内的各种BLAST数据库,对功能蛋白质编码基因、tRNA和rRNA进行了全面预测和高度注释。DC2的基因组分别有149、227、65、153、53和6个基因负责纤维素、半纤维素、木质素、果胶、几丁质、淀粉和菊粉的降解。抗生素和次生代谢产物分析软件(AntiSMASH)分析表明,DC2菌株拥有20个负责产生次生代谢产物的生物合成基因簇。还发现DC2菌株含有编码芳香族L-氨基酸脱羧酶的基因。总之,本研究全面了解了次生代谢产物的相关过程以及DC2菌株降解植物细胞壁的能力。
