Maternal inheritance of plastids in Encephalartos Lehm. (Zamiaceae, Cycadales).
The mode of inheritance of chloroplast DNA has been determined in Encephalartos by employing a restriction fragment length polymorphism analysis of chloroplast DNA. Artificial F1 hybrids were produced between a female specimen of E. natalensis and a male specimen of E. woodii. The hybridization patterns of all hybrids correspond, in all cases, with that of E. natalensis, and are different from that of E. woodii, thus indicating the maternal inheritance of cpDNA in cycads.
