title: Sequencing of the 16S-23S spacer in a ribosomal RNA operon of Zea mays chloroplast DNA reveals two split tRNA genes.
abstract: The nucleotide sequence of th 16S-23S spacer from a ribosomal RNA operon of Zea mays chloroplast DNA has been determined. It contains two tRNA genes, coding for tRNAlle (AUCU) and tRNAAla (GCGA), which are split by intervening sequences of 949 and 806 base pairs, respectively. Homology between the two introns suggests that they have a common origin.
