[Detection of multiple Ophiocordyceps sinensis mutants in premature stroma of Cordyceps sinensis by MassARRAY SNP MALDI-TOF mass spectrum genotyping].

Coexistence of the three known Os genotypes indicates the existence of possible transition point mutations within Os genes during germination and early maturation of Cs. Simultaneous detection of at least two unknown genotypes coexisting with those known mutants possibly evidences the transversion mutations within Os genes.
