摘要： The first dikaryotic genome of Ganoderma cultivar Zizhi S2 (56.76 Mb, 16,681 genes) has been sequenced recently. 98.15% of complete BUSCOs were recovered in this genome assembly and high-confidence annotation rate improved to 91.41%. Collinearity analysis displayed the nuclear genome were 80.2% and 93.84% similar to reference genome of G. sinense at nucleotide and amino acid levels, which presented 8,521 core genes and 880 unique orthologous gene groups. Among that, at least six functional genes (tef1-alpha, beta-tubulin, rpb2, CaM, Mn-SOD and VeA) and a newly discovered fip gene were highly similar 99.27%similar to 100% to those in reference genome. And the mt-LSU, mt-SSU and 13 PCGs in their mitogenome were also highly conserved with 99.27%-99.87% and 99.08%-100% identity, respectively. So that, this cultivar Zizhi S2 is confirmed conspecific with Ganoderma sinense (NCBI: txid1077348). The new fip gene (MN635280.1_336bp) existing a novel mutation which can be reflected on the phylogenetic tree and 3-dimensional model topology structure.
