Sažetak
The process ofamyloplast-to-chloroplast and leucoplast-to-chloroplast transformation in potato microtubers (solanum tuberosum L. cv. Istra) exposed to light was studied. After 12 h of light exposure, the characteristic chlorophyll fluorescence was already detectable usin a fluorescence microscope. At the same time, HPLC analyses showed the presence ofchlorophylls a and b. Simultaneously, the assembly of the LHCII protein complex was detected by Western blot analysis. The formation of the LHCII protein and appearance chlorophylls and carotenoids confirmed the development of the LHCII pigmented multiprotein complexes during light-driven differentiation of the chloroplasts. Electron microscope analyses showed the development of thylakoids in amyloplasts and leucoplasts leading to the formation of chloroplasts.
