WebSep 28, 2004 · Most of the angiosperm plants studied exhibit maternal inheritance of cpDNA, but about one-third of the genera investigated display biparental chloroplast inheritance to some degree (reviewed by Mogensen 1996). Much less is known about the inheritance of plant mtDNA, but it seems to be commonly maternally inherited. WebThe number of recombination events in the genealogy of the chloroplast suggests that recombination, and thus biparental inheritance, is not rare. Consistent with the evidence of recombination, we find that the ratio of the number of nonsynonymous to the synonymous polymorphisms per site is lower in chloroplast than in the mitochondria genome.
WebSep 29, 2009 · Biparental inheritance of chloroplast genes in Pelargonium was demonstrated at the level of DNA by Metzlaff et al. ( 1981 ). We extended the investigation of organellar inheritance in Pelargonium by including mt markers, and we show here that mtDNA is also inherited biparentally. WebFeb 4, 2024 · Most organelle genomes are inherited from the mother (1, 2), but biparental transmission of plastids has evolved independently multiple times.Approximately 20% of all angiosperms contain chloroplasts in the pollen generative cell, indicating at least a potential for biparental transmission (2–4).Although reasons for this are controversial (2, …
