  • To study the light-induced expression mechanism and protein transport into the chloroplast, a rice genomic clone (GrbcS) for the small subunit of ribulose 1,5-bisphosphate carboxylase (rbcS) was isolated and its nucleotide sequence was determined. Nucleotide sequence analysis of GrbcS revealed that the gene consists of two exons interrupted by an intron, encoding a protein of 175 amino acids including a transit peptide of 47 amino acids. These structural features of GrbcS are consistent with those of other rbcS genes from monocot species. Genomic Southern blot analysis suggested that the rbcS genes are present as a relatively small multigene family in the rice genome. Comparison of the nucleotide and deduced amino acid sequences to other rice rbcSs shows close sequence similaritiy. Conserved DNA sequences present in other light-responsive genes are also found in the 5’ upstream region of GrbcS such as G-box, 3AF1-binding site and GATA site. The possible function of these putative regulatory elements are discussed.
