Abstract excerpt

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...
