Chloroplast Replication and Growth in Tobacco

Abstract

Tobacco etioplasts replicate at least twice during light-induced development. Their size is doubled over the same period. The two processes do not show the same kinetics. 5-Fluoro-deoxyuridine inhibits chlorophyll synthesis during the normal course of "greening" by inhibiting chloroplast growth. This compound also inhibits cytokinin-induced chloroplast replication.
