Location of the single gene for the large subunit of ribulosebisphosphate carboxylase on the maize chloroplast chromosome.

Abstract

The structural gene for the large subunit of ribulosebisphosphate carboxylase (E.C. 4.1.1.39) in Zea mays is shown to be contained within a 2500 base pair sequence of chloroplast DNA. One copy of this DNA sequence is present in each circular maize chloroplast DNA molecule. It maps approximately 30,000 base pairs from the 5' end of the closest of two sets of rRNA genes and approximately 71,000 base pairs from the other set of rRNA genes.
