Elimination of plastids during spermatogenesis and fertilization in the plant kingdom

Ultrastructural and genetic investigations involving diverse species of plants have demonstrated that plastids may be transmitted either biparentally or maternally during sexual reproduction. In species in which plastid transmission is maternal, elimination of plastids from the paternal parent may o...

Summary:Ultrastructural and genetic investigations involving diverse species of plants have demonstrated that plastids may be transmitted either biparentally or maternally during sexual reproduction. In species in which plastid transmission is maternal, elimination of plastids from the paternal parent may occur in a number of ways: exclusion from the male gamete during spermatogenesis, loss from the motile sperm, exclusion during fertilization, or degradation within the zygote. These diverse ways in which maternal inheritance of plastids is achieved suggest that this inheritance pattern may have evolved independently many times in response to different selective pressures in different phyletic lineages.
