The complete mitochondrial genome of huperzine A-producing endophytic fungus <i>Penicillium polonicum</i>

Abstract

Huperzine A-producing fungus <i>Penicillium polonicum</i> Hy4 (CCTCC No.M2010086) was isolated from <i>Huperzia serrata</i> (Thunb) Trev. The complete mitochondrial genome of <i>P. polonicum</i> is 28 192 bp in length, containing 15 protein-encoding genes, 27 tRNA genes and two rRNA genes. The whole mitogenome is high in AT content (74.40%) and low in GC content (25.60%). The mitochondrial gene order and arrangement of <i>P. polonicum</i> are identical to those of other <i>Penicillium</i>. Phylogenetic analysis based on 14 concatenated protein-encoding genes showed that <i>P. polonicum</i> was close to <i>P. solitum</i>. This study reports the complete mitogenome of <i>P. polonicum</i> for the first time and provides valuable information for further exploration of mitochondrial evolution.
