Abstract
The rpoB gene for the beta subunit of rice chloroplast RNA polymerase was found to be highly expressed in unexpanded immature leaves that co ntained proplastids, indicating the specific expression of rpoB at an early stage of chloroplast development. A putative transcription start site (tss) was identified, but the 5' upstream region of the tss had no sequences resembling typical -35 and -10 elements. A palindromic se quence and high AT-content were recognized.
