Abstract

Organelle DNAs (orgDNAs) in mitochondria and plastids are generally inherited from the maternal parent; however, it is unclear how their inheritance mode is controlled, particularly in the plastids of seed plants. Chung et al. identify two factors that affect maternal inheritance in tobacco plastids: cold temperature and DNA amount in pollen.
