METABOLISM AND TRANSPORT IN NONPHOTOSYNTHETIC PLASTIDS

Plastids in non-photosynthetic tissue are the site of fatty acid, star ch and amino acid synthesis. The intermediates to support these activi ties are imported from the cytoplasm or generated by carbohydrate oxid ation within the organelle. This review considers the current understa nding of the nature of the substrates which are transported into such plastids, the interaction between pathways within the organelle which have a supply and demand relationship, and pathways which potentially compete for substrates.
