| Abstract: | Summary The existece of plasmid like DNA was demonstrated in senescent mycelia of Podospora anserina (strain s) by biophysical and electronmicroscopic methods. According to their contour length of about 1.4 and 2.7  m respectively the molecular weight for the monomer is in the range of 3·106.This work was supported by the Deutsche Forschungsgemeinschaft. The sojourn of P.A.L. for six months in Bochum was made possible by a Senior U.S. Scientist Award of the Alexander von Humboldt Stiftung (Bonn). |
