Geographic Genetic Diversity Study published

Late 2009 a study by Chinese researchers on the genetic diversity of Cordyceps/Ophiocordyceps sinensis on the Tibetan Plateau was published. Very interesting. I have not really studied it in detail, but the conclusion is that polymorphism of nrDNA ITS sequences suggested that O. sinensis spread from a center of origin in Kongpo (Nyingchi / Linzhi Prefecture) to Himalayan influenced southern regions of Tibet AR and subsequently spread to northern areas, where the diversity is much smaller.
