White rot fungi efficiently degrade lignin, a complex aromatic polymer in wood that is among the most abundant natural materials on earth. These fungi use extracellular oxidative enzymes that are also able to transform related aromatic compounds found in explosive contaminants, pesticides and toxic waste. We have sequenced the 30-million base-pair genome of Phanerochaete chrysosporium strain RP78 using a whole genome shotgun approach. The P. chrysosporium genome reveals an impressive array of genes encoding secreted oxidases, peroxidases and hydrolytic enzymes that cooperate in wood decay. Analysis of the genome data will enhance our understanding of lignocellulose degradation, a pivotal process in the global carbon cycle, and provide a framework for further development of bioprocesses for biomass utilization, organopollutant degradation and fiber bleaching. This genome provides a high quality draft sequence of a basidiomycete, a major fungal phylum that includes important plant and animal pathogens.
白腐真菌能高效降解木质素,木质素是木材中的一种复杂芳香聚合物,是地球上最丰富的天然材料之一。这些真菌利用细胞外氧化酶,这些酶也能够转化存在于爆炸物污染物、农药和有毒废物中的相关芳香化合物。我们使用全基因组鸟枪法对黄孢原毛平革菌RP78菌株的3000万个碱基对基因组进行了测序。黄孢原毛平革菌基因组揭示了一系列令人印象深刻的编码分泌氧化酶、过氧化物酶和水解酶的基因,这些酶在木材腐烂过程中协同作用。对基因组数据的分析将增进我们对木质纤维素降解(全球碳循环中的一个关键过程)的理解,并为进一步开发生物质利用、有机污染物降解和纤维漂白的生物过程提供一个框架。该基因组提供了担子菌门的高质量草图序列,担子菌门是一个主要的真菌门类,包括重要的动植物病原体。
