Abstract
The Arabidopsis seedling can follow two contrasting developmental programmes, photomorphogenesis in light and skotomorphogenesis in darkness. CONSTITUTIVE PHOTOMORPHOGENIC I (COP1) is an essential regulatory gene required for repression of seedling photomorphogenic development in darkness. Recent mutational and overexpression analyses of the COP1 gene suggest a central role for COP1 in light control of seedling development and point to functional implications of its structural domains. Cell biological studies of COP1 have provided a clue to how light regulates the repressive activity of COP1 and thus seedling development.Keywords
