Maternal inheritance of plastids and mitochondria in Cycas L. (Cycadaceae)

Molecular Genetics and Genomics, 2011
Cycas is often considered a living fossil, thereby providing a unique model for revealing the evolution of spermatophytes. To date, the genetic inheritance of these archaic plants is not fully understood. The present study seeks to document the process of organelle inheritance in an interspecific cross of Cycas species.
