sequences. In a previous work (Stern, DB, and Gruissem, W.(1987) Cell 51, 1145–1157), we
have shown that their role may be in RNA stabilization and as a processing signal that
establishes the mature mRNA 3′ end. In this report we have investigated the stability and
protein interaction of chloroplast mRNA 3′ IR-RNA sequences in more detail. Progressive
deletions into the 3′ IR-RNA sequences for the chloroplast cytochrome b 6/f subunit IV …
