✦ Synopsis

Tobacco chloroplast DNA contains a large inverted repeat sequence of 26 kilobase pairs (kbp). The inverted repeat is separated by 20 kbp small single-copy and 90 kbp large single-copy regions. We have cloned four DNA fragments containing each junction between the inverted repeat and the single-copy regions. The sequence analysis revealed the exact edges of the inverted repeat. A putative coding region for a ribosomal protein CS19 was found 4 base pairs (bp) away from the inverted repeat on the left margin of the large single-copy region. A sequence AGGAG, which is complementary to the 3' terminal sequence of tobacco chloroplast 16S rRNA, was found within the inverted repeat. A tRNA his gene was found 5 bp away from the inverted repeat on the right-hand margin of the large single-copy region.

In order to determine the localization of ribosomal protein genes on the chloroplast genome of Spirodela, we have followed two different approaches: First, antisera were prepared against purified 30S, 50S and 70S chloroplast ribosomal proteins from Spinacia. These antisera react with about two third
