is a wood-decaying fungus with great potential to be used in the bioconversion of agro-industrial residues and to obtain high-value-added products, such as biofuels. Nonetheless, the lack of high-quality genomic data hampers studies investigating genetic mechanisms and metabolic pathways in , hindering its application in industry. Herein, applying a hybrid assembly pipeline using short reads (Illumina HiSeq) and long reads (Oxford Nanopore MinION), we obtained a high-quality genome for the CCMB561 and investigated its genetic potential for lignocellulose breakdown. The new genome possesses 143 contigs, N50 of 1,009,271 bp, a total length of 46,748,415 bp, 14,540 protein-coding genes, 22 secondary metabolite gene clusters, and 426 genes encoding Carbohydrate-Active enzymes. Our CAZome annotation and comparative genomic analyses of nine spp. genomes revealed CCMB561 as the species with the highest number of genes encoding lignin-modifying enzymes and a wide array of genes encoding proteins for the breakdown of cellulose, hemicellulose, and pectin. These results bring to light the potential of this isolate to be applied in the bioconversion of lignocellulose and will support future studies on the expression, regulation, and evolution of genes, proteins, and metabolic pathways regarding the bioconversion of lignocellulosic residues.
是一种木材腐朽真菌,在农业工业残留物的生物转化以及获取高附加值产品(如生物燃料)方面具有巨大潜力。尽管如此,缺乏高质量的基因组数据阻碍了对其遗传机制和代谢途径的研究,进而妨碍了它在工业中的应用。在此,我们应用了一种使用短读长(Illumina HiSeq)和长读长(Oxford Nanopore MinION)的混合组装流程,获得了CCMB561的高质量基因组,并研究了其分解木质纤维素的遗传潜力。新基因组拥有143个重叠群,N50为1,009,271 bp,总长度为46,748,415 bp,14,540个蛋白质编码基因,22个次生代谢物基因簇,以及426个编码碳水化合物活性酶的基因。我们对九个物种基因组的碳水化合物活性酶组注释和比较基因组分析表明,CCMB561是编码木质素修饰酶基因数量最多的物种,并且拥有一系列编码用于分解纤维素、半纤维素和果胶的蛋白质的基因。这些结果揭示了该分离株在木质纤维素生物转化中的应用潜力,并将支持未来关于木质纤维素残留物生物转化相关基因、蛋白质和代谢途径的表达、调控及进化的研究。
