De-etiolation is Almost Color Blind: The Study of Photosynthesis Awakening under Blue and Red Light.

ABSTRACT: The synthesis and assembly of functioning photosynthetic complexes in chloroplasts developing from etioplasts during the de-etiolation of angiosperm seedlings are imperative for the plant's autotrophic lifestyle. This study compared the de-etiolation process under monochromatic red or blue light of equal photon flux density during a 24-h illumination period of etiolated Arabidopsis seedlings. The aim was to elucidate the impact of these light wavelengths on the etioplast-to-chloroplast transformation and the initiation of light-dependent photosynthetic reactions. Both treatments led to the formation of functional young chloroplasts; however, the etioplast-to-chloroplast transition and the assembly of photosynthetic complexes occurred unevenly, with individual steps tuned by red or blue lig
