DNA-DNA hybridization experiments using labelled cloned wheat mitochondrial DNA fragments showed that the mitochondrial DNA organization of embryogenic subcultures derived from embryogenic parts of Chinese Spring calluses is closely related to that of the initial Chinese Spring calluses whilenon-embryogenic subcultures derived from non-embryogenic fragments of Chinese Spring calluses exhibit a mitochondrial DNA organization similar to that found in non-embryogenic callusesCollection: Reprints Collection
