Abstract

The COP1 (CONSTITUTIVE PHOTOMORPHOGENIC 1) gene has been identified earlier from dicot species namely Arabidopsis, tomato and pea. The protein encoded by this gene acts as a molecular switch that negatively regulates the transition from the skotomorphogenic to the photomorphogenic mode of plant development. We have isolated and characterized the COP1 homolog from a monocot species, i.e. rice (var. Pusa Basmati 1). All the functional domains (Zn-binding RING finger motif, coiled-coil region, WD-40 repeats? cytoplasmic/nuclear localization sequences and protein-protein interaction domains) thatare known in the COP1 proteins from dicots are conserved in COP1 from riceas well. The transcript levels of COP1 vary in various tissues of the riceplant. These variations were found to be development-dependent and do not solely depend on the light conditions.
