abstract：:In the multicellular red alga Antithamnion spec. both rubisco genes (rbcL and rbcS) are encoded on the plastid DNA (ptDNA). Both genes are separated by a short A/T-rich spacer of 100 bp and are cotranscribed into an mRNA of approximately 2.7 kb. These findings are in extensive agreement with those obtained from two un...
