2.1 The genome characteristics of G.lucidum
The genome sequence of G.lucidum was sequenced by whole genome shotgun strategy and produced 3，738 megabases(Mb)clean data.The assembly was performed by SOAPdenovo，firstly generated 1，724 contigs with an N50 of 80，796bp and then assembled into 634 scaffolds with an N50 of 322，982bp.The length of scaffolds ranges from 1004bp to 1953398bp.Finally，we got a 39.9 megabases(Mb)draft genome sequence for G.lucidum.Although we could not assemble these scaffolds into chromosomes，by using k-mer analysis，the expected genome size was 42.53Mb，so these scaffolds covered 93.92% of the whole genome.The G+C content of the G.lucidum genome was 55.56%.The features of the assembled genome sequences are showed in Table 1.
