Arabidopsis FUSCA5 encodes a novel phosphoprotein that is a component of the COP9 complex.

The Plant cell - 1 May 1999

Karniol B, Malec P, Chamovitz D A

Abstract excerpt

The COP9 complex is a regulator essential for repression of light-mediated development in Arabidopsis. Using partial amino acid sequence data generated from purified COP9 complexes, we cloned the Arabidopsis cDNA encoding the 27-kD subunit of the COP9 complex and showed that it is encoded by the previously identified FUSCA5 (FUS5) locus. fus5 mutants exhibit constitutive photomorphogenic phenotypes similar to...
