Insertion polymorphism in pea chloroplast DNA

Abstract:
The chloroplast DNA of higher plants is suitable for restriction endonuclease analysis due to its size and homogeneity. We have analysed 48 different cultivars of pea (Pisum sativum) with EcoRI and HindIII. Of these, only 24 show the standard genotype, the remaining 24 comprise four different classes of short insertions, three of which are found at the same site. Even though this kind of insertion polymorphism has not been detected elsewhere in the plant kingdom, it is consistent with the discovery that the chloroplast DNA of pea is destabilised through the loss of an inverted repeat.

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.
