Protein nucleocytoplasmic transport and its light regulation in plants.
Light exerts a great influence on gene expression, physiology and development pattern in higher plants. Protein factors involved in these processes, such as the photoreceptor, phytochrome B, a key regulatory protein, COP1, and some bZIP transcription factors have been identified and their light-regulated movement between the cytoplasm and the nucleus has been demonstrated. These findings imply that nucleocytoplasmic transport plays a crucial role in light regulation in higher plants. This review summarizes recent investigations into plant nuclear transport systems and specific cases where nucleocytoplasmic transport is subject to light regulation.
