Abstract:
In a study of pollen ultrastructure in Chlorophytum comosum plastids were found to be present and apparently unaltered in both vegetative and generative cells. These ultrastructural data are consistent with the biparental transmission of plastids in this genus. However, mitochondria appear degenerate when compared to leaf mitochondria, exhibiting small myelin-like figures in addition to an abnormal cristae system. Since the plastids are not degenerate in the pollen of this species it appears that the transmission genetics of the mitochondria are determined separately from that of the plastid in higher plants.

Protein Transport to the Outer Chloroplast Membrane
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.
