We mapped and sequenced a novel chloroplast gene encoding a protein (348 amino acids) which shows a high sequence identity with both the decoded nuclear cs(ch‐42) gene product of Arabidopsis thaliana , and the C‐terminal half of the decoded ‘ crt A’ gene product of Rhodobacter capsulatus . The chloroplast gene ( ccs A) is split (two exons) and transcribed into a stable mRNA of about 1200 nucleotides. The putative protein may be involved in the biosynthesis of photosynthetic pigments.
