摘要：
The Norway spruce (Picea abies (L.) Karst.) mitochondrial DNA has been extracted from embryonal suspensor masses. In addition to a master chromosome, a family of plasmid-like DNAs were identified. These latter shared cross homologies but had no evident sequence homology with the master chromosome. The occurrence of mitochondrial plasmid-like DNAs was investigated in trees from different provenances. A vast majority of trees displayed extrachromosomal DNA elements of variable stoechiometry. For some trees, the sequences homologous to the extrachromosomal DNA elements were found associated with high molecular weight DNA.
