    <div><p><i>Lentinula edodes</i>, one of the most popular, edible mushroom species with a high content of proteins and polysaccharides as well as unique aroma, is widely cultivated in many Asian countries, especially in China, Japan and Korea. As a white rot fungus with lignocellulose degradation ability, <i>L</i>. <i>edodes</i> has the potential for application in the utilization of agriculture straw resources. Here, we report its 41.8-Mb genome, encoding 14,889 predicted genes. Through a phylogenetic analysis with model species of fungi, the evolutionary divergence time of <i>L</i>. <i>edodes</i> and <i>Gymnopus luxurians</i> was estimated to be 39 MYA. The carbohydrate-active enzyme genes in <i>L</i>. <i>edodes</i> were compared with those of the other 25 fungal species, and 101 lignocellulolytic enzymes were identified in <i>L</i>. <i>edodes</i>, similar to other white rot fungi. Transcriptome analysis showed that the expression of genes encoding two cellulases and 16 transcription factor was up-regulated when mycelia were cultivated for 120 minutes in cellulose medium versus glucose medium. Our results will foster a better understanding of the molecular mechanism of lignocellulose degradation and provide the basis for partial replacement of wood sawdust with agricultural wastes in <i>L</i>. <i>edodes</i> cultivation.</p></div
