Molecular Cloning and Characterization of a cDNA for the r Subunit of a G Protein from Rice

Abstract

We isolated a cDNA for the rβ subunit of a heterotrimeric G protein from rice (Oryza sativa L. cv. Nipponbare). The amino acid sequence deduced from the cDNA was 76% and 94% homologus to the sequences of the rβ subunits from Arabidopsis and maize (AGrβ1 and ZGrβ1), respectively.
